Red vs. Blue Timeline

"Time...line? Time isn't made out of lines. It is made out of circles. That is why clocks are round."

- Caboose in Let's Come to Order

This is a timeline listing all of the most important events of the RvB universe. Many of the events revolve around Project Freelancer and the Blood Gulch Crew.

Events prior to the Project Freelancer Saga

 * The Great War begins; this results in the UNSC losing their jurisdiction over the recently colonized planet Chorus.
 * Leonard Church and Allison meet and start a relationship; Carolina is born.
 * Sarge enlists in the UNSC, where he jumps out of high orbit and develops a fear of heights. At some point, he unknowingly becomes a simulation trooper due to poor test scores.
 * Felix and Locus enlist in the UNSC and form a rivalry. Their squad soon become involved in a harsh battle, where the two fight together to survive.
 * Allison enlists in the UNSC Marine Corps and leaves for the war. She is presumably killed in action a short time later.
 * Carolina and York meet at Club Errera.
 * After years of fighting, the UNSC rely upon many top-secret projects and operations created to help ensure their victory in the Great War. This results in the creation of Project Freelancer.

Project Freelancer

 * Leonard Church becomes lead Director of Project Freelancer and receives permission from the UNSC Oversight Sub-Committee to create the Alpha A.I. for his experiments. The A.I. is modeled after the Director himself and co-works with Aiden Price, who becomes the Counselor to Project Freelancer.
 * Freelancer agents North Dakota, South Dakota, and Carolina infiltrate an Insurrectionist Research facility in the Arctic to recover a data file.
 * A newly inducted Freelancer, Agent Texas, easily defeats agents Maine, York, and Wyoming in a training match, establishing the Freelancers' suspicion over her. Carolina is made jealous of her prominent skill. York is also injured during the match, leaving his left eye permanently maimed.
 * The Freelancers are sent on a mission to recover the Sarcophagus and a briefcase from the Insurrection.  During the mission, Agent Maine is shot several times in the throat, causing him to lose his ability to speak.  Nevertheless, the Freelancers successfully obtain both the Sarcophagus and the briefcase.
 * Through the use of the "Sarcophagus", an AI fragment, designated as "Delta", is harvested from the Alpha A.I.  More fragments are then harvested.
 * Agent Washington suspects Agent Connecticut is conspiring with an Insurrectionist. Around this time, Sharkface, an Insurrectionist who faced the Freelancers, is hospitalized due to his severe injuries and is later taken into custody.

A.I. Implantations

 * Carolina is assigned the Sigma A.I., which she later gives to Maine so he could communicate after his previous throat injury; around this time, Tex, York, and Wyoming obtain their own A.I.
 * The Freelancers (excluding Maine, Wyoming, Texas, and Florida), infiltrate an Insurrectionist-held space station at the UNSC Scrap Metal Recycling Station in search of their leader. During the infiltration, C.T. deserts Project Freelancer and is revealed to be working with the Insurrection.
 * North Dakota is assigned the Theta A.I. and is later put through a trial to test its ability in combat along with North Dakota. The UNSC Oversight Subcommittee is later formed and Malcom Hargrove becomes a member.
 * The Freelancers attend a class on A.I. theory, where Sigma obtains an interest in the fourth stage of A.I. rampancy: Metastability, and creates a "Meta" symbol, consisting of multiple A.I. symbols.
 * Florida and Wyoming are sent on a reconnaissance mission at an old shipyard at Longshore occupied by Insurrectionists.  Both agents spot C.T. and relay the information to the Director of C.T.'s affiliation with the Insurrection.
 * The Freelancers infiltrate the Longshore Shipyards, killing most of the soldiers along with C.T., who is injured by Tex.  However, C.T. and the Insurrectionist Leader escape before she dies and, as a result, the Leader takes C.T.'s identity along with important information regarding Project Freelancer.
 * Sigma and Gamma, manipulate Carolina into asking the Director for an A.I. implantation by using her jealousy of Tex.  Carolina does so and acquires two A.I. fragments - Eta and Iota.  This, in turn, halts the implantation of agents Washington and South Dakota.
 * The Freelancer A.I.'s are briefly exasperated due to hearing Allison's name from the Director during an unscheduled match between Agents Texas and Carolina.  This causes severe pain for Carolina, as she has two A.I. fragments implanted within her, and as a result, slips into a coma.
 * The Director and Counselor, with the help of A.I. fragments Sigma, Gamma, and Omega, harvest the Epsilon A.I. from the Alpha, who of which is severely deteriorating. The Director and Counselor then use a Huragok concealed inside the Sarcophagus to complete the process.

Freelancer Break-In

 * Washington undergoes neural surgery in order to acquire the Epsilon A.I. Upon entering Washington's mind Epsilon reveals several memories of Allison at once.  Washington's sanity is pushed to the limit, resulting in him being restrained and put under observation.  Epsilon, as well as all other assigned A.I., are scheduled for "decommissioning".
 * Agent Texas discovers from a data file, provided by C.T., that she is the Beta A.I., a byproduct of the torturing process conducted on the Alpha A.I.  She also learns of the Director's many crimes during the project.
 * Texas and York disband from Project Freelancer; Gamma forcefully removes himself from Wyoming causing him mental harm and it is rumored that Tex attacked him for his A.I.
 * Sigma fully manipulates Maine into becoming the "Meta" (a tool) in order to acquire all A.I. fragments into becoming one, meta-stable artificial intelligence. During this time, the UNSC give several locations to Project Freelancer to use for their simulation tests.
 * Tex recruits the help of York and North Dakota, who also learn of the Director's ulterior motives, in initiating a break-in upon the Freelancer frigate, Mother of Invention, hub of all operations for the project. During the break-in, York tries to convince Carolina to join them, but she doesn't listen, while Tex finds the Alpha and briefly speaks to him. During the mayhem, the Mother of Invention quickly loses orbit and crash lands on a frozen planet, where the Meta steals Eta and Iota from Carolina. She is then thrown off a nearby cliff and Tex then flees the area.
 * The Director and the Counselor decide to relocate the remains of the Alpha A.I. to a remote place where no one will find him or know who he is. They give Agent Florida the responsibility to look after Alpha.

The Blood Gulch Chronicles

 * The Alpha, now known simply as "Church", is stationed in Blood Gulch. He is deployed as a Blue Team member along with Tucker and Butch Flowers, who is head of the Team. Church is under the guise that he is fully human and not an A.I.
 * Grif, Simmons, and Sarge are the Red Team members who occupy the other side of the canyon from the Blue Team.
 * Sarge begins building a robot named Lopez.
 * During this time, Church from the future appears and shoves dirt on Lopez's switch, later causing his leg motors to short out.
 * Butch Flowers mysteriously dies of a heart attack; Tucker takes his armor for himself before burying him.
 * Butch Flowers' death is caused by Future-Church, when the latter gives him aspirin to prevent his fatal heart attack, not knowing that Flowers is allergic to the medication.
 * A new Warthog arrives at the Red base and Sarge leaves to see Command; Church and Tucker spy on the Red Team at this time.
 * Donut arrives at Red base as the team's newest member. Caboose arrives at Blue base as the Blue team's newest member, joined by a Scorpion-class battle tank.
 * Grif and Simmons send Donut on a fools errand to retrieve fake items. Donut inadvertently retrieves the Blue Team's flag after thinking their base was a "store".
 * Future-Church causes Donut to go to Blue base when he points him to the area, not knowing of who Donut is until a few moments later.
 * The Blues fail in retrieving their flag back from Donut during his way back to Red base. The Reds attack the Blues with the warthog after spotting the commotion. Caboose attempts to save his team with the tank, meeting Sheila, the tanks training AI, in the process. However, Caboose "kills" Church in a failed attempt to save his friends. Episode_8.png
 * Church's "death" is caused by his future self, when Church (from the future) disables Sheila's friendly fire protocol, unknowingly allowing her to kill friendly forces. Prior to this, Church overrides Sheila's name; changing it from F.I.L.S.S. to Sheila.
 * Caboose attacks the Red base, but Sarge having returned from command, uses a dropship to destroy Sheila forcing Tucker and Caboose to retreat.

Tex's Arrival

 * Tucker calls Blue Command for reinforcements. Vic, the Red and Blue teams' command assistant, sends Freelancer Tex. A "ghost" of Church warns the Blue team about the Freelancers and how Tex is one of the worst. He further explains Tex being involved in killing all the Blue team members on Sidewinder (except Church) and is the reason that Church never married his girl back home.
 * Tex arrives, infiltrates the Red base, and gets the Blue team's flag back, sticking Donut with a grenade in the process. Tex then gets captured by Lopez and Sarge, but Church quickly saves her by possessing Sarge after revealing that Tex is a female and is the girl he was going to marry back home.
 * Future-Church leaves his sniper rifle unattended when Tex attacks Red base, leaving Caboose to find it and later shoot it at a Church-possessed Sarge.
 * In all the chaos, Caboose shoots a Church-possessed Sarge, and nearly kills him, but the latter is quickly revived by Grif. Donut returns to Red base, now fully recovered, and has been given pink armor. Sarge installs a speech unit into Lopez; although a static surge damages the speech unit and causes Lopez to only speak Spanish.
 * Tex repairs the tank and uses it to attack the Reds once more. Unfortunately, Tex gets killed by Donut in the process. Due to Tex's "death" the Omega A.I., also known as O'Malley, leaves her body and enters into Caboose's.
 * Church inhabits Lopez's body and the Blue team have a eulogy for Tex and Church's old body. Tucker and Caboose then spray paint Church's armor (Lopez) blue.
 * Future-Church, under the guise of Capt. Flowers, contacts Vic who misunderstands him, causing Vic to think Red and Blue are the same and sends Frank Dufresne to Blood Gulch when told not to.

Doc's Arrival

 * Three months later, Medical Officer Frank DuFresne arrives at Blood Gulch; Caboose begins to act strangely and shows more aggression.
 * The Red team then attack Blue base and make demands for supplies.  The Blues refuse their demands and ask for a negotiation.  After the two teams negotiate, Frank DuFrense, now nicknamed "Doc", is given to the Red team in exchange for Grif to humiliate himself.
 * The Blue team attempt to activate Lopez's repair sequence in order to fix Sheila, but they inadvertently activate the warthog by remote control, causing it to nearly eliminate Sarge.
 * Tucker pulls out a wire on Lopez's body which causes Church to loose connection to the warthog and his legs.
 * Simmons and Grif attempt to return Doc back to the Blues, but the Blues refuse to take him back.  Simmons and Grif then refuse to let Doc back to Red base and abandon him in the middle of the canyon; Doc stays in a nearby cave.
 * Church leaves Lopez's body in order for him to fix his legs and Sheila, however Lopez attempts to rejoin his team.  The Red team mistakes Lopez for a Blue and attack him, causing Lopez to destroy the Warthog and defect to the Blue team.
 * Grif spies on the Blues, discovering Lopez fixing Sheila; this causes the team to vote for Simmons to become a cyborg. After fixing Sheila, the two fall for each other before Tex possess his body, having returned as a "ghost".

Conflict with O'Malley

 * Tex explains Caboose has been possessed by the Omega A.I. and tells them of her plan to kill it: Church and Tex will enter Caboose's mind, while Tucker attempts to have the Reds turn off their radios.
 * Church and Tex begin their search and meet Caboose's mental images; at Red base, Sheila runs over Grif, injuring him, and Donut warns the Reds of the "attack".
 * At some point, Future-Church tries to convince Lopez and Sheila not create their own robot army, but his words are what inspire them to rebel. He then tries to fix the Reds' teleporter, but when Sheila runs into the base during the "attack", it causes the teleporter to become damaged.
 * Tucker is able to make the Reds turn off their radios using Lopez's love song for Shelia; Church and Tex successfully force O'Malley out of Caboose's mind, but unfortunately O'Malley infects Doc after the latter was abandoned by the both the Reds and the Blues; Tex then disappears.
 * In the cave, Doc finds an "alien relic" and begins showing signs of O'Malley's possession. Grif is saved after Sarge transfers Simmons' organs into him after the latter's surgery. Sarge then informs the Red team about the need of getting Lopez back in order to access important information stored in Lopez's head that could change the war.
 * Sheila and Lopez decide to disband from the Blues, due to unfair treatment and create a robot army for themselves. As Sarge sends Grif and Donut to spy on Blue team, Donut discovers Doc and O'Malley discussing their plan to eliminate both teams, but as he leaves he is captured by Caboose and Tucker.
 * The Reds negotiate a trade with the Blues in order to get both Donut and Lopez back, in exchange for two robot bodies that Church, in Donut's body, demands for himself and Tex.
 * The Blues discover a note that Shelia and Lopez had left, informing them of their disbandment and plans for a robot army. Sarge then creates the two robots: one of which contains a microphone to spy on the Blues and the other contains a bomb.
 * At the trade-off, Shelia and Lopez arrive on their own, confusing everyone and resulting in a tense standoff. Sarge contacts command when Tucker learns that Vic works for both sides, making him believe that the war is fake. Before he can reveal this information, Tucker is hit by an explosive when Doc/O'Malley attack and kidnap Lopez. After Church inhabits the cobalt armored robot (which contains the bomb), O'Malley and Lopez escape through the teleporter, forcing both teams to join forces in order to retrieve Lopez (so the Reds obtain their information) and Doc (to heal Tucker).
 * Future-Church attempts to kill Doc/O'Malley with a rocket launcher, but ends up hitting Tucker instead.
 * Leaving Donut, Sheila, and the black armored robot behind, the Reds and Blues follow O'Malley through the teleporter, but end up in separate locations. In Blood Gulch, Tex inhabits the black armored robot and meets Donut; Church and Grif discover themselves on Sidewinder and are soon captured.

Into the "Future"

 * The teams are split apart due to a malfunction in the teleporter: Sarge and Caboose end up at Battle Creek where endless fighting between the Red and Blue Grunts takes place; Simmons is sent to the Teleporter Nexus; Church and Grif are imprisoned by a Red team on Sidewinder. Meanwhile, Tucker awakens from his injuries at Blood Gulch.
 * Simmons is able to rescue and reunite with Sarge and Caboose; Wyoming appears at Sidewinder and obtains a contract from Vic to kill Tucker and aid O'Malley.
 * Tex warns Tucker of the Freelancer that was hired to kill him, while Vic tricks the Reds' into believing Tucker's knowledge of the Reds and Blues being the same is a deception. Tex, Donut, and Tucker at Blood Gulch contact Sarge, Simmons, and Caboose, where Caboose unwittingly activates the bomb in Church's body.
 * Wyoming kills all the Reds on Sidewinder and leaves Church and Grif to starve to death; the teams reunite after Simmons and Donut reprogram their teleporters in order to get to Sidewinder. Tucker appears covered in black stuff (which prevents Wyoming to kill him as he can't identify him) while the doors to Church's and Grif's cell opens mysteriously. Tex, alone, tries to ambush Wyoming, but is captured by O'Malley.
 * Future-Church appears before Sheila and tells her something before departing to Sidewinder; there, he opens the door to Present-Church's and Grif's cell, freeing them. He then meets another Future-Church which tells him to meet "them" at the top of the ramp, confusing him.
 * The remaining Reds and Blues join forces and confront O'Malley as he activates the weather control device in Lopez; Simmons forms a plan to use the Grunts to defeat O'Malley, but a lightning strike from Lopez's weather device strikes Church, causing the bomb to be unable to be disabled. When the bomb detonates, everyone, except Church, is sent into the "future" while Church is sent to the "past", where he meets a computer named Gary. Church_&_Gary.png
 * Another Future-Church frees Tex before the bomb detonates and attempts to defuse the bomb by using a lightning strike from Lopez's weather machine, but in fact damages it, preventing it to be disabled.
 * A group of Future-Churches discuss a plan at the top of Sidewinder; the "last" Church decides to improvise and simply join the others when the bomb goes off, ultimately sending him to the point after the teams attack on O'Malley's fortress.
 * Gary tells Church of the Great Prophecy, which states the Great Destroyer will come take the Great Weapon, kill Gary, and bring doom the universe. Church deduces the Great Destroyer is Caboose and, with the aid of Gary, he leaves a message for Caboose to warn him, while he goes back to Blood Gulch in an attempt to change time by preventing certain situations from occurring (see previous secondary bullets).
 * The Reds, Tucker and Caboose find themselves in a wasteland and discover a destroyed jeep; meanwhile, O'Malley and Doc find Lopez as a disembodied head and establish a new base at Zanzibar.
 * O'Malley enlists the Red Zealot to become one of his henchmen, as Tex spies on him; The Reds, Tucker, and Caboose are able to fix the jeep and later contact Tex on the radio, who tells them of O'Malley's location. The Reds, Tucker, and Caboose reunite with Tex, who has created a bomb to be dropped in the base; the group begin making a plan, but are spotted by the Red Zealot who tells O'Malley.
 * The Reds and Blues attack O'Malley fortress, but are put under fire from the Red Zealot and Lopez. After Tex snipes Lopez, Tucker finds a mysterious sword and uses it to kill the Red Zealot; O'Malley/Doc then retreats and escapes. Caboose, having carried the bomb into the base, finds a computer which has a message from Church which states it's 1,856 year old.
 * The Reds and Blues learn from the message of the Great Prophecy and Church tells Caboose not to bring the Great Weapon into the complex as it will result in the base to lock down, but Tucker brings it in unknowingly; worst is that Caboose has already set the bomb down allowing it to countdown. Before the bomb detonates, however, Church appears out of nowhere and convinces Gary to deactivate the bomb.
 * Church discusses with the Blues about the weapon Tucker found and later Caboose discovers that the bomb, named Andy, is sentient, while the Reds discover a distress signal from a surviving Red team and decide to locate them; unknown to either team, they are being spied on by a unknown character.
 * As the Red team prepares to go search for the surviving Red team, O'Malley/Doc and Lopez have created an army of robot duplicates, which O'Malley orders them to kill everyone and retrieve a "device". The robot army proceeds to attack Zanzibar; the Reds leave Donut behind due to the warthog only having three seats, but Donut steals O'Malley's motorcycle and catches up with his team, only to discover the signal led them back to Blood Gulch.
 * Tex steals the sword from Tucker, but can't get it to activate; O'Malley and his army are defeated by an unknown figure, and as Church begins questioning Gary who the destroyer is, he is attacked by the figure, whose in fact an Alien.

The Sacred Quest

 * Church (as a "ghost") tells his team about the Alien and they attempt to face it, but are scared away when seeing it; meanwhile at Blood Gulch, Simmons, Grif, and Donut discover that Sheila is still active, but Sarge doesn't see her.
 * Simmons tries to convince Sarge that Sheila is real, but Sarge disregards his statement and demotes him, believing he has gone insane. At Zanzibar, Tex attempts to kill the creature, but is unsuccessful and returns as a "ghost"; the Blues send Caboose to distract the Alien, while Church and Tex get their bodies back.
 * Caboose is able to befriend the Alien, but the team is unable to understand him. At Blood Gulch, Simmons, having been banished, is about to commit suicide but Sheila cheers him up, shows him the Blue base, and reveals she has lost some of her memories.
 * Simmons tries to earn the Red team's trust back by telling them he has captured the Blue base and Sheila, but Donut, now second in command, won't let him to speak with Sarge.  Simmons then joins the Blue team and paints his armor partially blue.  Tucker and Caboose try to teach the Alien English, but upon using his sword, Tucker is attacked by the Alien while Tex convinces Andy to translate.
 * Andy translates for the Alien and reveals that he was sent on a quest to retrieve the sword, but is unable to use it as the sword has locked itself to Tucker, making him the only one able to use it; Tucker is then forced to join the Alien on the quest along with Andy and Caboose.
 * At Blood Gulch, Simmons attacks the Reds with the aid of Sheila; Grif tries to talk him back to join Red team, but Simmons takes Grif hostage.  As a result, Sarge and Donut attempt to rescue Grif, but Church returns to Blood Gulch and knocks out Sarge.
 * Meanwhile, the quest team pass through the "Great Burning Plains" and soon reach the "Great Swamp," where they find Tex, who joins them in exchange for the sword when the quest is completed.  At some point during this time, the Alien implants Tucker with a parasitic embryo.
 * Simmons and Church negotiate with Donut to trade the Red's jeep for Grif and Sarge while the quest team reach the "Great Freezing Plains" and discover that the fortress is being guarded by the Battle Creek Grunts.
 * Tex attempts to use her cloaking to take the fortress, only for the Grunts to realize her and the team's location; Tucker uses the sword to unlock a door, revealing a ship that the Alien takes before being shot down by Wyoming.  Wyoming flees and Tex then chases after him, leaving Tucker, Caboose, and Andy to return to Blood Gulch.

Out of Mind

 * At the "Great Freezing Plains", Tex confronts Wyoming and demands to know where Omega is located. Wyoming, however, escapes and tells his boss that Tex took the bait.
 * In order to gain access into Omega's fortress Tex finds and recruits York and Delta. After explaining her plans to capture Wyoming to them, Delta and York help Tex infiltrate the fortress, eliminating numerous Grunts at the roof of the fortress during a firefight. After killing all of the Grunts, Tex and York battle Wyoming.
 * Unfortunately when Tex's rifle jams, York attempts to cover her, but is shot by Wyoming. Delta decides to stay with York as he dies, and briefly distracts Wyoming so Tex can interrogate him. Wyoming tells Tex that Omega has moved himself into a new host and is heading back to Blood Gulch. Tex then knocks him out and attempts to search his communication logs, but Wyoming suddenly teleports away.

Return to Blood Gulch

 * Church tells Simmons his thoughts about each Red team member and later reveals to Sheila that he knows that the "new blue" is Simmons, and begins to manipulate him. When Simmons challenges his authority, Church unknowingly makes contact with Vic Jr., an "descendent" of Vic.
 * Simmons returns to Red base to reveal the info he obtained from Vic Jr., while the remaining quest team return to Blue base, revealing the events that had occurred as Tucker starts to show signs of "sickness". The Blues decide to contact Doc/O'Malley and Lopez to diagnosis the ill Tucker, resulting in the three returning to Blood Gulch. Meanwhile, Simmons, after changing his armor back to maroon, rejoins the Reds.
 * Donut finds Lopez and Sarge makes Lopez replay a secret message sent by Command, but it's played in Spanish. At Blue base, Doc reveals that Tucker is pregnant.
 * To translate the message, Sarge kidnaps Andy, who was with Caboose, and replaces him with a skull. Caboose returns to Blue base and tells the Blues that Andy is dead. Church, as a result, takes Sheila to confront the Reds, as Tucker is about to give birth.
 * The Reds discover that the message is generic instructions, depressing Sarge before Church attacks them with Sheila. As Sarge calls for reinforcements, Andy reveals to Church that aliens infect other organisms with parasitic embryos, in order to reproduce. Caboose tells Church that O'Malley has vanished and Doc has successfully delivered Tucker's alien baby, causing Church to return to Blue base. Donut attempts to go see the baby, but a ship, presumed to be the Red's reinforcements, lands on him.

Sister's Arrival

 * Sarge retreats to Red base to obtain equipment to rescue Donut, while Simmons and Grif watch the ship. Meanwhile, Church retreats to Blue base, where he is informed that the alien baby is causing havoc and has consumed some of Caboose's blood, with the aid of Doc, leaving the latter unconscious.
 * With Sheila's aid, Church attempts to take the ship from the Reds, but Sheila leaves after Sarge returns, causing him to retreat as well. Afterwards, Church finds Doc taking care of Junior, Tucker's alien child.
 * As the Reds attempt to save Donut, the ship opens revealing Grif's sister. It is also revealed that Donut fell into the Underground Caves under Blood Gulch. Sister reveals that she was sent to Blood Gulch to also replace a dead commanding officer, with Sarge believing that Command has made a mistake. However, Grif convinces Sarge that Command "never make mistakes" and Sarge is then buried alive as a result.
 * Caboose and Tucker recover from their injuries, and Church fills Tucker in on the events that have happened while he was in a coma. Meanwhile, with Sarge now buried, Simmons attempts to take control of the Red team, but Sister reveals that the "blue guys" were the ones that sent her to Blood Gulch. Grif then confesses that Sister is color blind and sends her over to the Blue team.
 * Simmons then tells Grif that Sarge is missing and the two discover a cave under his grave, which they believe Sarge fell into. Because they are undermanned, the two enter the cave to find Sarge.
 * At Blue base, Tex returns and begins attacking the Blue team, as Tex believes one of them is affected by O'Malley. She ultimately calms down after meeting Sister.
 * Sarge, having fallen into the caves, finds Donut (as well as another Red and Blue base) and later is able to contact Simmons and Grif on the radio. As they set a point to reunite at, Simmons and Grif are drugged by an unknown group and Grif is kidnapped.

Recovery One

 * At Omega's fortress, Freelancer Washington, now known as Recovery One, arrives to the deceased Agent York to recover Delta and take York's enhancements to prevent it from being stolen. As he obtains Delta, Wyoming appears and attacks Washington, but Wyoming retreats before York's armor detonates. Washington escapes, planning to take Delta back to Command, but Command reveals that another agent is gravely injured and Washington must go to check it out.
 * Washington later discovers that North Dakota has been killed and South Dakota has been knocked unconscious. He awakens her to find out what she knows, only to figure out North's equipment and Theta, his A.I., have been stolen. Wash then fakes South's death in order to have her help him and reveals that three other agents were killed by an assailant and are currently being followed by the latter.
 * Washington and South are then attacked by the assailant, thus South is forced to have Delta implanted in her armor to increase their chances to survive. When they attempt to attack, however, South shoots Washington in the back in order to escape from the assailant with Delta. As she leaves with Delta, she reveals that she's Recovery Two, and is abandoning Project Freelancer.

Omega's Final Assault

 * Back at Blood Gulch, the Blues notice a problem with Sheila, so Caboose is voted to distract her while the others deactivate her, believing she is possessed by the rouge A.I. Caboose attempts to distract Sheila, but when she is about to reveal who the Omega A.I. is in, she is deactivated by Tex.
 * When Simmons awakens, he is met by Sarge and Donut, and knowing that Grif has been taken, the Reds go search for him, eventually finding him unconscious with Sarge's shotgun. When Grif awakens, he tells his team of his captors, one of which was Andy, and what they may be planning.
 * Meanwhile, as the Blues transfer Sheila to the dropship in order to learn where O'Malley is, Tex ultimately reveals her journeys and that Wyoming disappeared after she knocked him out. Upon learning that Wyoming was also given an A.I. named Gamma, Church deduces that Gary was, in fact, Wyoming's A.I. and has tricked them.
 * When Vic Jr. contacts the Blues to tell them to attack the Red base, they split into different teams: Church, Tex, and Tucker will cross the canyon to Red base; Doc, Sister, and Jr. will go through the caves; and Caboose will watch over Sheila during her transfer. Back in the caves, the Reds find a room with a large computer screen which shows a majority of Blood Gulch and wonder who would have made and used it.
 * Church, Tucker, and Tex arrive at Red base. Sheila is completely uploaded into the dropship, and tells Caboose that Omega has affected the "blue leader", which causes the team to assume Church is affected.
 * Sarge contacts Vic Jr. for support, but Simmons hears an echo in the caves, discovering Vic Jr. before he disappears, causing Simmons to believe that he has deceived both teams. The Reds then make plans to occupy Blue base and begin to exit the caves.
 * Church tells his team that he was never promoted to leader of the Blue team, but then realizes who Sheila truly meant. Meanwhile Doc, Sister, and Junior find Lopez in the caves, but are soon captured by a Green Alien and Captain Flowers, now possessed by Omega.
 * Red team soon find Andy, who tells them Omega's plan before the Reds leave in order to take Blue base. At Red base, Wyoming ambushes the Blues and holds them at gun point. Church contacts Caboose unnoticed, in an attempt for him to take the tank and come rescue them. The tank arrives, but Gary (Gamma) is in control of it.
 * As Caboose comes to help, Wyoming uses his time distortion enhancement to prevent himself from losing (in two of which where Caboose dies), but Tucker is immune to the distortion due to his sword and then kills Wyoming. However, the time distortion effect creates numerous Wyoming "clones", who, along with Gamma, then attack the Blues. The Reds see this and realize that the Blues will need help.
 * Tucker, Caboose, and Sheila formulate a plan and succeed in removing Gamma from the tank and putting him behind a firewall in the Pelican. The Wyomings begin to overrun the Blue team, but the Reds (except Donut) arrive in the Warthog, saving them and killing the majority of the clones. The last (dying) Wyoming reveals they plan of using Junior and the sword to take over the alien race and end the Great War, which convinces Tex to aid them.
 * In the caves, the Green Alien takes Junior to the ship as Omega attempts to rejoin Tex, leaving Sister and Doc, who heals Flowers and uses the computer to monitor the situation, behind. As Tex gets into a tense conflict with Church and Tucker, Omega ends up jumping into Simmons. Tex and Church meet with Red team, forcing Omega to jump into Caboose with Tex following him. Church, realizing the risks, tells Sarge to disable the Pelican, but the Reds instead plan to destroy it.
 * Church then enters Caboose's mind and finds Tex and Omega. As the teams reunite, Flowers is shot in the head and the Reds plant Andy in the ship. After Church forces them out and leaves, Tex takes the sword from Tucker and Omega jumps into Donut, Sarge, Grif, Doc, and Church (who doesn't feel different after being infected), until finally reaching Tex. Omega/Tex then leaves in the Pelican with the helmet of Wyoming, but Andy detonates after takeoff. Church depressed, returns to Blue base with his team and the Reds do the same.

Events prior to the Recollections

 * Washington, who survived his wounds because of York's armor enhancement, is recovered by Command and begins to recover from his injuries.
 * The Great War ends and Malcom Hargrove becomes the Chairman of the UNSC Oversight Subcommittee as well as the CEO of Charon Industries.
 * Those on Chorus attempt to govern themselves, but a Civil War erupts between the New Republic and the Federal Army of Chorus for control over the planet. The factions later employ Felix and Locus to help them win the conflict, but they and many other mercenaries are hired by someone known as "Control" to escalate the war.
 * The Reds and Blues (with the exception of Sarge, Lopez, and Sister) are relocated to new bases in order to keep the Alpha's location secret once again. Simmons, Grif, and Caboose are sent to Rat's Nest; Church is sent to Outpost 48-A; Tucker and Donut are sent to unknown locations. Doc also leaves Blood Gulch around this time.
 * At some point, "C.T." join forces with Smith and forms a group to find alien artifacts in a desert.
 * Though heavily damaged, the crew on the Pelican survive and crash land on Valhalla, after a year passes (due to Wyoming's armor enhancement). Omega then possess the Blue soldiers of Valhalla.
 * After the Blues at Valhalla destroy their own radio tower, Omega infects the Red soldiers. The Meta arrives at the location and kills all the remaining Blues, in order to capture the A.I. The Meta then kills the remaining Reds, leaving only one soldier alive, and captures Omega, Gamma, and Tex. Due to recent events, the Chairman and the UNSC begin to investigate Project Freelancer.

Pursuit for the Meta

 * Recovery agents Six and Nine are sent to Valhalla to investigate the recent tragedy, but are ambushed and killed by the Meta.
 * A recovery team arrives at Valhalla and find Private Walter Henderson, who tells Command what happened. Washington is then sent to Blood Gulch in order to obtain help from "specialists" who've dealt with Omega.
 * After obtaining information from Sarge, Washington goes to Rat's Nest to obtain information from Caboose. Caboose joins Wash on his search and suggests help from a friend to aid them; as they leave, the Meta kills all the Rat's Nest Blues and begins to follow them.
 * Arriving at Outpost 48-A, Washington and Caboose meet Church; Church at first denies joining them, but upon learning about Tex's ship, he reconsiders. As they leave to Valhalla, the Meta contacts Sarge and tricks him to stop Wash, while South, who has also been following Washington, reveals herself, and Delta, before the Meta attacks.
 * After hearing the Meta's false message, Sarge leaves Blood Gulch to reunite the Red team. When arriving at Rat's Nest, Sarge saves Simmons and Grif from being executed by their own squad and learns that Grif is now a Sergeant. Simmons and Grif then join Sarge to track down Washington and the Blues. After Sarge had left Blood Gulch, Lopez kills Sister at some unknown point.
 * Wash, Church, and Caboose then arrive at Valhalla, which is under Recovery Force investigation. They secretly investigate the crashed Pelican and discover Sheila operating it at minimum capacity. They also discover the last audio log recorded before the ship's crash, detailing that the Green Alien and Junior escaped and Tex, Omega, Gamma, and Andy occupied the ship when it crash landed. Suddenly, Washington gets a recovery beacon from Command, detailing that South Dakota and Delta are under attack. As a result, Wash, Church, and Caboose head for their location.
 * Back at Outpost 48-A, South Dakota and Delta take refuge from the Meta within a Domed Energy Shield. South attempts to abandon Delta and save herself, but Washington, Church, and Caboose interfere and engage the Meta. After Caboose prevents South from escaping by shooting at her, Church tries to kill the Meta with a Rocket Launcher, but the Meta stops him with a Time Distortion unit and escapes because he is running low on power. As Washington, Church, and Caboose approach South, Delta explains to Wash that South was going to betray him to save herself, as she did to her brother North Dakota. As a result, Caboose inserts Delta into his helmet and Washington kills South.
 * Afterwards, Delta begins to explain the history of the A.I., including Alpha. Wash stops Delta short and comes to the conclusion that the Meta is 'malfunctioning'. Wash is then informed by Command that the Meta is Freelancer Agent Maine and asks where the Meta would go to 'recharge'. Caboose and Church realize that he would most likely be heading to Zanzibar.

Joining Forces

 * When Wash and the Blues arrive at Zanzibar they find and attack the Meta while he's recharging, causing him to retreat. As Wash and Church chase him the Reds arrive and interfere and Caboose, who was separated, is knocked out by the Meta and loses Delta to him.
 * Washington realizes that Caboose is injured and tries to negotiate a truce with the Reds using their codeword, but Grif ignores this and confronts the Meta, believing he is also a Red. The Meta begins to attack them, causing the Reds to join with the group before Washington goes to check on Caboose and uses a machine gun turret to chase the Meta away.
 * The group try to awaken Caboose, but to no avail. Simmons then distracts Washington as Church enters Caboose's mind to wake him up but finds a message from Delta who tells him "Memory is the key," but he is seen by Washington in his 'ghost' form after leaving Caboose.
 * Church soon explains to Washington on what happened to him and what he is but causes an argument between the two teams. Washington stops them and reveals that their war are "tests" for Freelancers, before sending the Reds to find vehicles to use. Wash then hears Church's message from Delta, and realizes they must go to Command.
 * The group head to Valhalla in order to steal military vehicles to sneak into Command, but are soon discovered by Recovery soldiers causing Simmons and Wash to destroy two vehicles to kill them. Seeing an opportunity, Church leaves them to find Tex at Blue base, but finds nothing.

Project Freelancer Destruction

 * After Washington scorns Church, the group unite and Sarge states that the Reds will continue to help if Grif is demoted, which Wash does. They begin to discuss a plan to sneak into Command, in which Caboose suggests that they simply "look" like Freelancers and use a tank to enter Command without being noticed. The plan succeeds and the group enter the base, but the Meta has followed them into Command as well.
 * Washington and Church go alone to locate the 'key' to stopping the Meta and Project Freelancer while the Reds and Caboose are tasked with surveillance. Sarge decides to have Simmons hack into command's files to erase the Blues. Meanwhile, Washington and Church enter the A.I. Containment Facility and discover Epsilon, the key.
 * After Simmons hacks into Command, Sarge quickly erases all files regarding Blue team, and Grif finds a message from Tucker. Meanwhile, Washington begins to explain the origin of the A.I., where Alpha was tortured in order to split into multiple A.I. fragments, and then reveals that Church is the Alpha, explaining his situation and other occurrences.
 * Church soon argues with Washington that he isn't an A.I., but is interrupted when an alarm goes off. The two escape with Epsilon and return to the Reds and Caboose. Freelancer soldiers begin to attack them, but the Meta reveals himself and soon kills them, giving the group a chance to find vehicles for them to escape command.
 * Washington decides to stay behind and trick the Meta to follow him while the Reds and Blues escape with Epsilon. Wash ventures deeper into command in order to activate the base's EMP which will destroy the A.I. and physically shut down Project Freelancer. As he is activating the EMP, the Counselor and Director attempt to stop him through negotiation, but they allow the Meta to kill Washington instead. Suddenly, Church appears next to Wash and distracts the Meta long enough for Wash to activate the EMP, which destroys all technological equipment, including the A.I., in the area. Fortunately, the Reds and Caboose escape with Epsilon intact.
 * The Reds and Caboose are awarded the Valhalla bases from the UNSC for helping bring Project Freelancer to justice, but Caboose keeps Epsilon to try to make a new best friend. The Chairman, who had been messaging the Director during the events, reveals that the Director will be imprisoned for his past crimes before the Director reveals why he committed the crimes. At some point, the Director avoids custody while the Counselor is arrested.

Relocated

 * At Valhalla, Caboose attempts to build a new best friend using Epsilon, while the Reds try to contact Lopez to come help Sarge make a new weapon for their Warthog.
 * Simmons confronts Caboose about his actions, but obtains no info. Meanwhile, Grif climbs up the Red base in order to regain power for it and finds segments of a ship blocking the tower. He tosses a grenade to destroy the debris, but is caught in the explosion and falls off the base.
 * Sarge then contacts Lopez, in which Lopez informs him that he killed Sister, winning Blood Gulch for the Reds, but Grif finds it unlikely. When Lopez arrives, he builds a Hologram Chamber to test the new weapon: an EMP cannon for the Warthog, but the team realizes that it has a far lower firing rate than the original turret. Suddenly, Grif finds Donut, in which the latter warns him that "He needs help. It's under the sand," before going comatose.

Caboose's Mission

 * With Donut still in a coma, the Reds realize that Command lacks any information on the Blue team, due to Sarge erasing them from their systems. Meanwhile, Caboose continues his 'secret best friend project' to no avail and begins telling Epsilon (inaccurate) stories about the past.
 * Donut eventually awakens, confronts Caboose and informs him of a message he found from Tucker meant for Church, before fainting; as the Reds attempt to retrieve Donut, Simmons realizes Sarge has no respect for him and disobeys Sarge's orders.
 * After Caboose drives off the Reds, Donut regains consciousness and the two explain their adventures before contacting Washington at the UNSC Maximum Security Detention Facility via video phone. Caboose reveals to Wash that he was relocated to Valhalla and is in possession of Epsilon, leading Wash to ask permission to speak with the Chairman. Wash confronts the Chairman, revealing to him that he knows who is in possession of Epsilon and will return the A.I. to the Chairman, in return for his freedom.
 * After the call ends, Donut returns to Red base and Caboose, remembering what Sarge and Donut said about a hologram room, sneaks into Red base with Epsilon. Caboose enters the Reds' holo chamber, allowing Epsilon to use the chamber's power to take the form of Delta. Epsilon-Delta suggests that they go find Tucker, in order to rescue him and hopefully obtain a chance in getting large power that could aid in resurrecting Epsilon.
 * After Epsilon-Delta returns to storage, the Reds discover Caboose and, upon hearing him going on a mission, Grif and Sarge decide to go with him to ensure the Blues be added back into Command's database. Simmons refuses to join and stays with Lopez and Donut at Valhalla.
 * Caboose, Sarge, and Grif take the EMP Warthog and travel to the desert, but enter a minefield. Suddenly, a man on an intercom tries to save them. Meanwhile, Simmons takes command of the remaining Reds and plans to destroy Blue base to prove a point to Sarge.
 * With (some) help from the man on the intercom, the desert team escape the minefield at the cost of their Warthog; they then meet the intercom man, C.T. (really the Insurrection Leader) and his partner Smith, an alien. Meanwhile, Simmons' plans are halted when he discovers, from Donut, that Caboose plans to use Epsilon to build a robot best friend, when he was suppose to give it to the UNSC. Simmons also accidentally insults Lopez in the process.
 * Simmons tries to contact Sarge about Caboose still having Epsilon, but can't contact him. At the desert, C.T. tells the desert team that they must leave as soon as possible, as they are a military dig team of paired humans & aliens, and the group could threaten a peace treaty between the two species. Though suspicious, the desert team agree and begin preparing to leave on a loan Warthog.

Old Friends and New Enemies

 * As Sarge and Grif prepare to leave, Caboose enters the dig team's Elephant. C.T. then confronts Sarge and Grif and plans to kill them if they don't reveal who they 'really' are, until the Elephant's alarm goes off.  The desert team is captured by the dig team, but suddenly Tucker attacks the dig team and rescues the group, taking them inside the temple.
 * At Valhalla, as Lopez creates two motorcycles, the Meta arrives at Blue base and is discovered by Donut and Simmons. After Simmons (and eventually Donut) retreat to Red base, the Reds defend and fortify the base against the Meta.
 * After the desert team secure the temple, Tucker explains that the dig team the group met are imposters who killed the original team, and Tucker (and Junior) is now an ambassador to both groups. Caboose soon discovers a monitor in the temple which he installs Epsilon into, giving him Church's personality, but Epsilon has trouble remembering the group (due to Caboose's stories) and his own past. Eventually, Epsilon takes command of the desert team.
 * At Valhalla, the Reds eventually run out of ammo. Donut, believing Lopez came up with the idea, suggest they should try to find the Meta's vehicle and take it to escape. With no other choice, Simmons decides it's their only hope and leads the group in a suicide run to find the vehicle.
 * After C.T.'s group break into the temple to face the desert team, the aliens begin to worship Epsilon, as they believe he's a holy relic/figure. However, when one of C.T.'s soldiers deactivates Epsilon, the aliens betray the human party. C.T. then steals the downed Epsilon, leading the desert team and Smith to pursue C.T. in a tense vehicle chase. The desert team eventually defeat C.T.'s men and disable C.T.'s vehicle, forcing him to flee as Tucker follows him. Tucker is soon cornered by C.T. on top of the temple, but Epsilon appears and, learning from a video, fires a laser from his eye to kill C.T., leaving only the aliens left.
 * At Valhalla, Simmons finds the Meta's vehicle, but the Reds discover that the Meta removed the starter and is approaching them. Suddenly, Washington arrives, orders the Meta to stand down, and then demands Epsilon from the Reds. Confused by the two working together, the Reds don't answer him. Growing impatient, Wash shoots Lopez in the head and Donut in the chest, presumably killing them. Afterwards, Wash and the Meta, now working together to find Epsilon, take Simmons prisoner.

Secret Archives

 * The Meta and Wash force Simmons to call a medical officer to check the Meta, resulting in Doc arriving and being taken prisoner as well. At the desert, Epsilon is worshiped by the aliens until he suddenly gets a vision, seemingly of Valhalla. Sarge, fearing what it could mean, attempts to contact Simmons.
 * With Epsilon's aid, Sarge and Grif are able to contact Valhalla; as Simmons explains the events to Doc, he is forced by Wash to answer the call and trick the group that things are fine. However, Simmons (accidentally) sends a secret message, allowing Sarge to deduce what has happened. As a result, Sarge and Grif (and Epsilon) head to Valhalla in order to rescue Simmons from captivity.
 * When Sarge arrives at Valhalla, Washington goes to confront him while the Meta watches the prisoners, but Simmons comes up with a plan to use Doc's medical scanner to overload the Meta. When Sarge is confronted by Wash, he gives Grif a signal to use the Warthog to incapacitate Washington.
 * Doc is able to weaken the Meta using Simmons' plan, causing the Meta's time distortion to overload. However, the Meta punches Doc into a wall, forcing Simmons to abandon him. He then joins Sarge and Grif, but the Meta destroys their Warthog; Epsilon then arrives and is able to aid in their escape before fainting.
 * At the desert, the aliens begin to attack Caboose and Tucker for the disappearance of Epsilon. The Reds return and hide Epsilon before Epsilon-Delta appears to tell the group to ensure Epsilon doesn't pursue all his memories or it will "repeat the cycle". At Valhalla, Washington and the Meta interrogate Doc.
 * When Epsilon-Church awakens, he and Caboose leave the desert, as the others follow, and discover a Freelancer Offsite Storage Facility where they meet F.I.L.S.S. Meanwhile, Doc reveals all he knows to the Wash and Meta and the two head to the desert with Doc as their captive.
 * At the Freelancer storage facility, Epsilon uses a robot body to 'resurrect' Tex when the Reds and Tucker arrive, forcing the group to fight against her. At the desert, the pursuit team arrive and find C.T.'s armor, before they are confronted by the aliens.
 * After the ex-Freelancers free Doc from his wall, they try to negotiate with the aliens, but when the aliens insult them, they kill the remaining aliens. As Epsilon-Tex beats the Reds and Tucker, Epsilon possess a robot body for himself and Caboose activates armor lock to stop her, but also locks everyone else.
 * The Reds' and Blues' armors are soon unlocked by F.I.L.S.S. and Epsilon is able to convince Epsilon-Tex to help them, unlocking all team units' armor, including Donut. Meanwhile, the pursuit team search the desert temple before the Meta discovers the Epsilon unit.
 * When the Meta reluctantly reveals the unit, the pursuit team begin modifying it to capture Epsilon and prepare to leave, but don't know how to track the A.I. At the storage facility, the teams begin finding info about Project Freelancer and Simmons discovers some armor enhancements that the group could use.

Revelation

 * Epsilon discovers audio files of the Director revealing Tex's origins before he and Epsilon-Tex leave the facility to Sidewinder, the location that was in his vision, to discover the truth. Afterwards, Simmons begins testing the enhancements (a speed unit) on Grif but discovers that they can't function without an A.I.
 * At the storage facility, after F.I.L.S.S. inputs the Blues back into command's data, the Reds discover that the events in Blood Gulch were all a simulation test and that the Reds and Blues are in the 10% of worst soldier scores, depressing Sarge to the point where he quits the army. Meanwhile at Sidewinder, Epsilon-Tex tells Epsilon about the break-in before shooting him in order to attract the pursuit team to their location.
 * The pursuit team, having followed Epsilon's recovery beacon, arrive at Sidewinder and prepare to capture him, but are caught in Epsilon-Tex's trap. At the facility, Caboose learns of Epsilon's injury and begs for the others to come help, with Sarge replying he'll help, to the others shock. Sarge then gives a passionate speech about each character's positive traits and states they are the only ones who can stop what's left of the Freelancers from getting away with their crimes, which convinces everyone to go. Simmons then reveals a Pelican they can use to get to them quicker and Grif is chosen to be the pilot.
 * Upon recovering from the blast, Wash and the Meta begin to fight Epsilon-Tex as Doc and Epsilon watch. During the fight, Epsilon-Tex uses several weapons and destroys the terrain to face them, but her strategy ultimatley fails, as the Meta eventually captures her with the capture unit. Now having an A.I., the Meta betrays the group and uses Epsilon-Tex to operate his armor enhancements, but before he can kill Washington, the Reds and Blues arrive in time and crash land on the surface.
 * As the teams regroup, they discover the unit is damaged, forcing the teams to work with Wash as they go look for supplies to prevent it from shutting down. Epsilon soon reveals to Wash that Tex was based on failure, which means that no matter what the situation, she will always fail and believes he's the only one that can save her.
 * However, the Meta rises out of the snow and incapacitates Epsilon and Washington. The Reds and Tucker soon fight against the Meta and Grif takes his brute shot during the battle. Wash gives Sarge the tow hook of the warthog and he confronts the Meta face to face before being grabbed. However, by using the same strategy at Valhalla, Sarge connects the tow hook to the Meta's armor as Grif and Simmons push the damaged warthog over the cliff, taking the Meta down as well, killing him.
 * Upon regaining the Epsilon unit, Epsilon enters it to find Epsilon-Tex, but the unit shuts down, trapping him inside. After Doc treats Wash's injuries, the teams decide to fake his death and have him join the Blue team so he can avoid life imprisonment before a squad of UNSC Police arrive to inspect the area. Inside the unit, Epsilon realizes that he just needs to be patient to find Tex and be happy, so he begins to relive the events of the Blood Gulch Chronicles with memories of the Reds and Blues inside the memory unit.

Events after the Recollections

 * The UNSC confiscate the Epsilon unit for evidence and store it at a UNSC storage facility; somewhere else, Carolina, who survived her fall using her grappling hook, begins to search for the Director for revenge.
 * Doc leaves the teams and returns to Valhalla, where he discovers Donut before treating his injury. After Doc saves his life, Doc and Donut begin living together at the base.
 * On Chorus, Control has the Space Pirates kill several leaders of the New Republic and Federal Army of Chorus in order to escalate the Civil War to the point the planet's inhabitants are eradicated.
 * Vanessa Kimball becomes the fourth leader of the New Republic.
 * The Reds and Blues at some point meet Carolina who ask for their help to rescue Epsilon and later find the Director, which they accept.
 * The UNSC label the Reds and Blues as wanted criminals due to hiding Wash as well as their attempts to rescue Epsilon, but the teams do not learn of this.

Inside the Memory Unit

 * Inside the Epsilon unit, Church joins the memories of Caboose and Tucker on spying on the Reds, but notices several differences from the original events before confronting the Reds to 'correct' it.
 * When Church confronts the Reds, he realizes that each of the Reds' personalities (except Simmons) is different and tries to reason with them to change; meanwhile, Tucker and Caboose return to Blue base, in which Caboose calls Command for reinforcements, believing Church is dead.
 * After Donut shoots Church in the foot, the latter returns to Blue base and learns of Cabosse calling for reinforcements and believes Tex will be sent. At Red base, the Red's slowly obtain their original personalities. Sarge builds Lopez to aid the team, but Simmons becomes jealous of Lopez as he begins to take his duties. Meanwhile, at Blue base, Church explains to his team that their world is actually inside a memory unit.

MIA

 * One day, Grif suddenly goes missing and Sarge and Simmons discover a "ransom" note stating Grif will die unless they meet their demands. At Blue base, Caboose is trying to organize the Blues' supplies while Tucker, having spied on the Reds, believes they are acting suspiciously.
 * After contacting Vic and obtaining Doc's support, Sarge and Simmons confront the Blues, believing they have taken Grif, but realize they aren't responsible. The Blues agree to help the Reds' in return for their supplies.
 * When the Blues, Sarge, and Simmons try to go to a city for help, they get lost in a forest and find the Blue team Grunts. There, their leader gives them directions on how to get to the city.
 * When they arrive at the city, the group meet Tucker's Informant Guy, who gives them little to no information. However, Caboose and Church find Grif with Donut who had taken him so he could go shopping and the note was a misunderstanding; thus, when they return home, the Blues take the Reds' supplies but don't have enough room to hold it at their base resulting in the Blues returning the supplies back to the Reds.

The Wall

 * At some point, Sarge becomes suspicious about a wall near Red base and makes it the team's current objective to find out what's behind it. At Blue base, the Blues obtain a new falcon and consider what they can use it for.
 * After Grif fails to ram through the wall with the warthog, Sarge sends Simmons and Lopez to steal the Blues' tank to destroy the wall and forces Grif to climb it. Meanwhile, Tucker and Church argue about who should pilot the falcon and decide whoever Caboose picks will pilot the vehicle.
 * Caboose picks Tucker and Church tries to bargain him with the sniper rifle. However, Simmons comes to the conclusion that the falcon will benefit them better than the tank. So, he steals the vehicle with Lopez and discovers the falcon is named Phil. Yet, he crashes Phil through the wall as Grif reaches the top, only to discover another wall.

Moving Forward

 * At the UNSC Archives, a rescue team consisting of Carolina, the Reds, and Blues find the Epsilon unit and begin trying to remove Epsilon from it, causing "tremors" to occur in Epsilon's memory of Blood Gulch.
 * Inside the Epsilon unit, Simmons tries to get rid of Lopez due to his growing jealousy but harms himself, and the latter takes his identity to obtain equipment to study the tremors occurring in Blood Gulch. Meanwhile at Blue base, Tex arrives and, after Church lies about a killed team mate to have Tex stay longer, decides to help them kill one of the Reds.
 * Disguised as Simmons, Lopez gathers data on the tremors using the equipment he obtained, but is shot by Tex, deactivating him. After Simmons recovers, he studies Lopez's data and reveals to the other Reds that the "planet" is breaking apart and they may die in the process. Back at Blue base, the Blues try to keep Tex there longer, but when she's alone with Church, she reveals that she knows what she is and Church has a realization as well.
 * Sarge comes to the conclusion that in order to stop the planet from breaking apart, they must detonate a bomb in its core. Sarge then orders a large excavator online to dig to the core and Grif goes to Blue base to insult the Blues, to the point they will make a bomb, which Tex does, creating an Epsilon version of Andy. She then takes him to Red base while he's active in hopes that he kills them. However, Andy doesn't explode, causing both parties' plans to fail.
 * The Reds decide to contemplate what they assume to be their last moments, while Tucker and Caboose leave the canyon with the tank. At Blue base, Epsilon tells Tex that sometimes you have to let things go to be at peace; thus he "forgets" Tex so that he can finally be at peace with himself.
 * Suddenly, the memory unit rips open and reveals the original Caboose and Sarge, who forcefully extract Epsilon from the unit, while the others (outside the archives) defend against UNSC forces. When Epsilon is removed from the memory unit, he soon meets Carolina, who reveals to him that she needs his aid to help her find and kill the Director.

Finding the Director

 * After being freed by Carolina and the Reds & Blues, Washington reveals to Epsilon that he has become the new leader of the Blue Team. Sarge and Caboose also explain to Epsilon of Carolina's motives to find the Director. After Grif kills two UNSC soldiers, the teams regroup and begin to move out.
 * The team takes a break at Zanzibar, much to Carolina's chargin. While the Reds and Caboose discuss their role in Carolina's "mission" and realize they might be wanted criminals, Epsilon and Tucker spy on Washington and Carolina's discussion about Sigma and Maine, along with the Director's influence on their pairing, before Epsilon and Tucker are discovered. After leaving, Carolina assures Wash that she can lead the squad and later decides they must find "C.T."
 * The group later arrives at the desert, where the Reds and Blues decide to work together in order to discover Carolina's motives. Simmons suggests they implant Epsilon into her Mongoose. Meanwhile, Washington leads Carolina to C.T.'s helmet, in which Carolina tells Washington of the events at the Longshore Shipyards and how exactly it came to be here. She then receives a data pad from the remains.
 * Carolina returns to the group after Simmons and Caboose install Epsilon into her Mongoose. Washington, meanwhile, searches the data pad within the Elephant and discovers information on Epsilon's monitor. After Tucker and Caboose tell her of its location, Carolina becomes furious and decides to temporarily leave in order to finish some "business", unknowingly taking Epsilon with her.
 * Carolina arrives at the abandoned fortress where York died and apologizes for not listening to him, before Epsilon reveals himself. He states that the others just want to make sure they can trust her but Carolina tells him that she doesn't trust anyone anymore, because of her past. Epsilon, however, shows her York's data logs of him speaking with Delta about Carolina; at the end, York states that he understood Carolina's actions and only wishes she could let things go. Thus, Epsilon earns Carolina's trust and she decides to give the others a chance.
 * At the desert, the Reds and Tucker are nervous about their situation, but Sarge tells them that they'll be fine as long as they stick together. Meanwhile, while spying on Washington, Caboose tells him that they are friends and that the teams trust him, to his surprise. When Carolina and Epsilon return, they reveal that they are going back to Valhalla.
 * When the group arrive at Valhalla, Tucker and Caboose confront Epsilon on his relationship with Carolina, but Epsilon states that she's a complicated person. After warning Carolina of a possibility of an ambush, Simmons and Sarge look for Lopez to repair him, but find Doc and Donut living in a hut near Red base.

Redemption

 * After Wash, Carolina, and Epsilon search the Pelican and find only dog tags, Carolina becomes irritated and orders Wash to gather the others to leave, much against his resentment. After he leaves, Carolina confesses to Epsilon she feels inferior to Tex and discovers the dog tags are actually C.T.'s which contain files of Project Freelancer; Epsilon then enters it and finally "remembers everything" upon returning.
 * As Washington gathers the Reds and Blues, he hears Simmons and Grif discuss "why they are here?" and come to the conclusion the Director is responsible. However, Sarge states that although true, the teams are reunited again and are in a safe location, but if they go after the Director, things will only get worse.
 * The teams are gathered into the Holo-Chamber, where Epsilon and Carolina reveal the Director's location. Carolina and Epsilon explain that the Reds and Blues will be the distraction, while they go kill the Director, but the teams argue that they only agreed to find him and aren't willing to die for their vendetta. Carolina soon threatens them, but Wash forces her to stand down and orders the two to leave to protect his friends. Enraged, Epsilon blames the group for all his problems and states they are nothing but problems. Hurt, the Reds and Blues leave in response, as Epsilon and Carolina feel guilty for what they have just done.
 * After Carolina and Epsilon leave, the two teams try to continue their daily shenanigans, but they soon argue over the Meta's brute shot, which Grif kept. However, Doc stops them and tells them how much they've changed and in the end, everyone got what they wanted. Moved by this and realizing they've always won by staying together, the group decide to go help Epsilon and Carolina. Then, the UNSC Police arrive at Valhalla to arrest them, but the Reds and Blues steal their hornets to get to the Director's location quicker.
 * When Carolina and Epsilon arrive at the storage facility, they meet F.I.L.S.S. and discover that the Director has created hundreds of Tex-drones in his attempt to resurrect Allison. Carolina, with Epsilon's aid, soon fights them, but is eventually beaten. However, before the Tex-drones can kill Carolina, the Reds & Blues arrive in time to save her and they reconcile their relationship before fighting the Tex-drones. As the group gets overwhelmed by the remaining drones, Epsilon enters every drone and is able to put them to rest after saying goodbye to Tex.
 * Epsilon and Carolina finally go confront the Director, who is watching a video of Allison. Epsilon tells him that he must pay for all the people who were harmed by his actions, but Carolina, seeing the Director already suffering, comforts him and reminds Epsilon that the past doesn't define you. As the two rejoin and leave the facility with the others, the Director orders F.I.L.S.S. to erase all Freelancer files, including herself, and he commits suicide with Carolina's pistol.

Events after the Project Freelancer Saga

 * The UNSC pardon the Reds' and Blues' crimes and honor them as heroes due to their actions of bringing Project Freelancer to justice as well as stopping several major threats. As a result, the teams become known as some of the greatest military soldiers in the galaxy and their exploits in taking down Project Freelancer become common knowledge across the galaxy.
 * Several armor enhancements of Project Freelancer become accessible throughout the galaxy; specifically to the inhabitants of Chorus.
 * Donut and Doc decide to stay in Valhalla while the others go on a UNSC spacecraft to return to Blood Gulch. At some point, Donut and Doc somehow reactivate Lopez (who now lacks a body).
 * During the spacecraft's flight, it rips in two and crashes on the faraway planet Chorus, with the only known survivors of the crash being the Reds, Blues, and Carolina.
 * Carolina and Epsilon decide to leave the group to continue to redeem themselves by stopping others who've stolen Freelancer equipment without saying goodbye so that they're "not gone, just somewhere else."

Crash Landing on Chorus

 * The Reds and Blues use the wreckage of the spacecraft to create two bases to live in and a communication tower in order to contact anyone for rescue. Sarge also discovers a robot kit in the ship's wreckage.
 * Washington soon orders Tucker to do training drills for his negligence behavior and Sarge decides to keep one half of Red base to himself and forces Simmons and Grif to share the other.
 * Depressed due to Epsilon's disappearance, Caboose goes for a walk alone and discovers a damaged war robot. At Red base, Simmons becomes frustrated due to his team disorganization and uncleanliness.
 * Sarge builds Lopez 2.0, who speaks in Spanish, from the robot kit to help work on the communication tower. As Wash and Tucker work on the tower, Caboose begins to repair the war robot.
 * The Reds go to the tower to offer their aid to Wash and Tucker, but they soon argue. However, Lopez 2.0 fixes the tower, allowing them to contact Donut and tell him of their situation. After Donut confirms he'll gather a team to rescue them, Caboose introduces the others to Freckles, the war robot.
 * When the Reds and Blues contact Donut, they unknowingly alert the Federal mercenary Locus and Rebel mercenary Felix of their presence, who begin to search for them. At Valhalla, Donut informs Doc and Lopez of the others' situation and the three obtain the help of a pilot to take them to Chorus.
 * At the crash site, the Blues discuss what to do with Freckles before Wash decides to send them to do drills while he searches the ship. Sarge, paranoid of Freckles, sends Simmons and Grif to spy on the Blues, but Simmons decides to stay with the Blues due to Wash's superior leadership methods.

Internal Conflicts

 * Wash returns to Blue base, but becomes annoyed by Tucker's lazy behavior and Simmons being with them. When Grif returns to Red base and informs Sarge that Simmons decided to stay with the Blues, Sarge overreacts and attacks Blue base using the warthog and Grif, causing an fierce argument to erupt.
 * During the argument, Freckles mistakenly promotes Caboose to Blue Team leader and takes Simmons hostage when he tries to return to Red Team. Sarge then attacks Freckles, but the latter destroys the warthog just before Donut, Doc, and Lopez arrive. Although happy at first, the group becomes furious when they learn that Donut allowed the pilot to leave with the ship and proceed to attack the "rescue team." Unknown to them, Locus finds their location and begins to spy on the Blood Gulch Crew.
 * Back at their respective bases, the Blues (and Simmons) are forced to follow Caboose's orders, in fear of Freckles, while the Reds and Doc formulate a plan to destroy Freckles once and for all. To do this, Sarge, Grif, and Doc enter the ship and find several items: a Sticky Grenade launcher, Teleportation Cubes, and a large Mantis.
 * Suddenly, the three spot Washington passing by inside the ship and quickly dismantle the large Mantis without being seen, with Grif personally taking the "future" cubes with him. Meanwhile, Wash constructs an unknown object inside the ship and fires at a crate in search for a conductor. Felix also discovers the group's location during this time.
 * At Blue base, after discovering the ship provides a nearly endless amount of power, Simmons creates the internet and Basebook (a social interactive website) in order to communicate with those across the canyon while being held captive by Freckles. Afterwards, Washington and Tucker reconcile their relationship when Tucker confesses he misses Church and Wash admits he doesn't know how to lead.
 * At Red base, while Lopez tells his experience with the Red Team to his successor to convince him of their stupidity, Sarge begins to reconstruct the large Mantis and Grif begins to experiment on teleportation cubes to learn more about them. Elsewhere, Locus returns to his base and gathers a small team of federal soldiers to go "test" the Blood Gulch Crew.
 * At the crash site, Wash soon confronts Caboose and tells him that he has replaced Church for Freckles to cope with the pain of Church leaving them, but also apologizes for not being a better friend. As a token of goodwill, Wash gives him a new helmet, which Caboose accepts and gives Wash back his Captain position, moving the others. At Red base, Sarge completes the construction on the mantis, nicknamed "C.C.", despite missing several parts. She soon malfunctions and targets everyone in the canyon before shutting down, but Donut notes she targeted 16 individuals, despite the fact that all together they're only 11.

Battle at Crash Site Bravo

 * Suddenly, the small team of Federal Army soldiers attack Blue base, but are quickly killed by Tucker and Freckles. As the Reds regroup with the Blues, Locus nearly snipes Wash in the head, but the latter is saved by Felix, who makes his presence known to the teams. Locus injures Felix and also appears before the Blood Gulch Crew, asking them to come with him. The group refuse and have Freckles attack Locus, but Locus cloaks away before stating that he will return.
 * After Doc treats Felix's wounds, Felix tells the Blood Gulch Crew that they are considered to be some of the galaxy's greatest soldiers and have crash landed on the planet Chorus. He also explains that a civil between the New Republic and the Federal Army of Chorus is currently in progression and asks the group to help the New Republic win the war. Unfortunately, the Reds and Blues refuse, only wanting to leave the planet. Soon after, Felix radios the Rebels and informs them of his status. He then tells the Blood Gulch Crew to begin fortifying their bases and prepare for Locus' return.
 * At Red base, Simmons rejoins his team and creates a minefield to fortify the canyon while Grif and Doc discover that the teleportation cubes have different frequencies that change their effects, but Doc disappears after he's caught in one of their blast radius.
 * At Blue base, Felix informs Wash that Locus is a mercenary working for the Federal Army and explains that armor enhancements have spread across the galaxy. He then encourages Wash to rekindle his old habits, prompting the latter to return to his steel armor color. Suddenly, the group are attacked by Lopez 2.0, who snapped and took control of C.C.'s body because of Sarge's orders, and the Federal Army, forcing them to engage.
 * As Freckles battles Lopez 2.0/C.C. he becomes damaged. Donut utilizes a teleportation cube and Simmons' minefield to destroy Lopez 2.0/C.C., but is soon knocked unconscious by Locus. In order to recharge power to Freckles, Tucker races to Red base and destroys Basebook (which has been using all of the power supply), successfully allowing Simmons to power up Freckles. When Tucker is caught at gunpoint by a Fed, Lopez, now with Lopez 2.0's body, saves him and the two regroup with the others.
 * As the Blood Gulch Crew fight back, Locus uses his Railgun to incapacitate Sarge and Wash. In addition, both Lopez and Freckles are also downed during the battle, with the former getting sniped at by a Fed and the latter becoming severely damaged by Feds while attempting to protect the group. Luckily, New Republic reinforcements arrive through a cave, but many are are killed in battle.
 * With Locus and the Federal Army closing in, Felix, Tucker, Simmons, Grif, and Caboose retreat through the cave. As Wash recovers and sees the others escaping, he orders Freckles to "Shake!", prompting the latter to stomp on the ground and cause the cave to collapse, sealing off the entrance. Wash, Sarge, Donut, and Lopez are then taken captive by the Federal Army, while Freckles is destroyed.
 * Tucker, Simmons, Grif, and Caboose are then taken underground to the New Republic Headquarters, where they learn that the others were left behind and captured. The four are then gathered by Felix to see General Vanessa Kimball, the leader of the New Republic, who offers if they can help the New Republic take back Chorus, they can save their friends and leave the planet when the war ends. Kimball reminds them that the civil war has gone on for too long and has taken too many lives. She then adds that the young, inexperienced, Rebel soldiers are scared, yet have hope because of them, convincing the four to take on leadership positions and join the New Republic.
 * At a unknown location, Locus communicates with his "superior" and informs Control about obtaining a crate from the UNSC Crashed Ship. Locus then suggest executing the captured Blood Gulch Crew members, but his superior declines and challenges him, raising his suspicions. Control reaffirms for him to obey orders before stating that they would meet soon, who is revealed to be Carolina on the other end.

Leading the Armies

 * After Washington, Sarge, and Donut recover from their injuries, they spend some time in captivity at F.A.C. Outpost 37 before meeting General Donald Doyle, the leader of the Federal Army of Chorus. Doyle explains that the Federal Army are not a tyranny and believes the New Republic are a group of terrorists of Chorus. Doyle then promises Wash, Sarge, and Donut that he will allow them to leave the planet with their friends if they help the Feds defeat the rebels, which they reluctantly agree with.
 * When they repair and reboot Lopez, Locus reveals that Freckles was destroyed after refusing to surrender. As the Reds and Wash become uncomfortable due to Locus' presence, Emily Grey, a Federal Army doctor, asks Locus to leave them alone. Locus complies and gives Wash a storage unit containing Freckles' "heart and mind," before Grey gets acquainted with the group.
 * Simmons, Grif, Tucker, and Caboose are promoted to captains and each obtain their own squad in the New Republic. Weeks later, Simmons, Grif, and Caboose take part in a training exercise with their squads, but it goes poorly and they are scolded by Kimball.
 * Meanwhile Tucker, his squad, and Felix infiltrate F.A.C. Outpost 22, where they plant several C-4 explosives around the compound. While there, Tucker manages to gain information on the captured Reds and Blues but causes his team to be found out by the Feds, resulting in the deaths of Rogers and Jason Cunningham.
 * After Grif and Simmons tell the recruits how they defeated the Meta, Kimball assembles the captains after Tucker's group returns to the New Republic Headquarters. Informing them that she knows their friends are being held at a dangerous outpost, Kimball gives the captains five days to assemble a new squad, comprised of the best of their respective platoons, in preparation for a potential rescue mission.
 * The captains choose Katie Jensen (Simmons' lieutenant), Antoine Bitters (Grif's lieutenant), John Smith (Caboose's lieutenant) and Charles Palomo (Tucker's sole surviving recruit) for the rescue mission while Tucker is voted as the squad's leader. Despite their persistence, Felix refuses to aid the captains.
 * Carolina and Epsilon, who has now improved his capabilities as an A.I. and utilizing the memories of the other A.I. fragments, infiltrate an abandoned F.A.C. Munitions Facility with their armor enhancements. After stealing classified files of the Space Pirates, Carolina and Epsilon uncover data about prototype weapons along with an audio log detailing Locus and Felix's plot in the Chorus Civil War. Control orders them to kill the Reds and Blues if they reunite, resulting in Carolina and Epsilon deciding to rescue their friends after obtaining Teleportation Grenades.
 * Simmons and Jensen create the Helmet Camera for the rescue team and Tucker decides they'll capture Felix to prove they are ready for the mission. Although they improve overtime, the team is laughed at by the rebels as Felix continues to humiliate them, infuriating Tucker.
 * When Tucker argues with Felix, Kimball stops them and speaks with Tucker in private to offer her aid. She also informs him of Felix's past and that three previous leaders of the New Republic were assassinated before her. Meanwhile, Simmons notices that Grif is acting like Sarge unknowingly, horrifying Grif.
 * Tucker meets with the other captains and suggest they'll do the rescue mission on their own. Although doubtful, the four agree to the plan as they don't want to put their recruits in danger and leave a message explaining themselves. When the captains stop at the Desert Refueling Station, they find and spy on four dark-armored mercenaries speaking to Control and Locus about the "captured" Reds and Wash before the mercenaries vanish.

Battling the Space Pirates
To be continued...
 * At the New Republic Headquarters, the recruits discuss if their captains will return after finding their message before Felix leaves to stop them. Meanwhile, the captains arrive at F.A.C. Outpost 37 and melt some ice to break-in when Caboose suggest doing so. After distracting the Feds by damaging the base's pipes, the four unexpectedly run into Washington, Sarge, Donut, and Lopez, confusing both parties.

Inconsistencies

 * Church states that he was sent to Sidewinder prior to coming to Blood Gulch, but it's revealed he was sent to Blood Gulch immediately after the break-in. It's unknown whether the memories he has of Sidewinder are true or implanted memories.
 * This also brings to question if the Sidewinder Blues were real and if Tex killed them.
 * Throughout the timeline, the exact relations of the locations have been questioned, as they switch between being on the same planet and being an entire planet themselves.
 * The only "planets" named in the series are Earth, Sidewinder, and Chorus. A fourth "planet", where Blood Gulch is located, has varied in relation with other locations.
 * In Season 1, Omega jumps into Caboose after hearing the low chances of survival before Tex attacked Red base. However, in the episode Silver Linings, Omega is shown to possess Caboose after he notices Future-Church, which was after Tex's attack.
 * When York was first introduced in Out of Mind, he stated that his eye injury was caused by Omega, but in Season 9, Maine and Wyoming are shown to be real ones responsible.
 * Although MIA and Where There's a Will, There's a Wall have been confirmed canon, the period of time in which they take place is unknown as the events inside the Epsilon unit occur within a short period of time, with little jump cuts made, making the mini-series contradict in several areas of the timeline. However, because the Reds show their original personalities during the two mini-series and Tex does not appear in any episode of the two mini-series, it can be assumed that they occurred between Familiar Feelings and Captive Audience.
 * The amount of time the Reds and Blues have known each other has varied between a few years (3 to 4 by Season 10) to nearly a decade. This amount of time increases as seasons go on.

 * Season 12 takes place several weeks after the events of the Season 11 finale.
 * However, The Federal Army of Chorus and Long Time No See both take place between Lost But Not Forgotten and Oh Captains, My Captains.
