History WeUsedToBeFriends / VideoGames

* Shepard and the Virmire Survivor in ''VideoGame/MassEffect2''. Joining up with terrorists (no matter how noble your intentions) after [[LockedOutOfTheLoop apparently faking your death]] will do that. Especially when the leader of the terrorist group in question does not want your old friends anywhere near you.

* ''VideoGame/MetalGear2SolidSnake'': Solid Snake and Gray Fox. Not that they didn't still respect each other. There wasn't much ill will at the end of their climactic battle, either. [[spoiler:It's subverted in ''VideoGame/MetalGearSolid'' where Snake declares he and Fox were still dear friends in spite of being on opposite sides of the war, and [[NothingPersonal that trying to kill each other over differing allegiances didn't mean they had to end their friendship]], much to the utter confusion and eventual HeelFaceTurn of Naomi (Fox's ''sister'') who had spent the better part of her life hating Snake and plotting revenge on him for "betraying" and killing her brother.]]
* ''VideoGame/MetalGearSolid4GunsOfThePatriots'': [[spoiler:Big Boss and Major Zero's We Used To Be Friends is partially the cause of the Metal Gear Saga. Over time, they went from close friends to the most bitter of enemies. Why? Because they were both so arrogant in their opposing (wrong) beliefs about what their idol, the Boss, wanted for the world that they each [[StartOfDarkness went to extremes to fulfill their personal interpretations]], dividing The Patriots and causing Zero to create Solid and Liquid. Whilst at the end Big Boss no longer feels hate for his old comrade, it is far too late for them to repair their friendship as [[DownerEnding Zero's advanced age had left him a brain dead shell]].]]

* Red and Blue from ''VideoGame/PokemonRedAndBlue'' were friends however as they grew they became rivals due to their similarities (same height, same age, etc). Future games depict them as having mended their friendship.

* In ''VideoGame/ShovelKnight'' the titular character and Polar Knight used to be friends. Both encourage the other to change allegiances before fighting, and even after his second defeat the Polar Knight still believes Shovel Knight should join the Order.
** There's also Black Knight. [[spoiler:Prior to the events of the game, they were in the same team as Shield Knight, and Black Knight's attempts to hinder Shovel Knight were meant to prevent him from killing Shield Knight (who has become possessed by The Enchantress).]]

* ''VideoGame/SpiderManPS4'':

** This trope ended up tragically happening between Atreus and [[spoiler:Sindri]] at the end of ''Ragnarök''. Beforehand, the two used to be close friends especially after Atreus helps [[spoiler:Sindri and Brok reconcile with each other]] where the latter helps him in the 3-year search for Týr as well as accompanying him in talking to Freya behind Kratos' back, even comforting him after an argument with his father. However, their friendship ended up taking a hit when Atreus decides to go defect to Asgard as well as striking [[spoiler:Sindri]] during his bear-induced transformation but despite resentful about it, he still cared for the kid to the point that he gave Atreus a way home if he needs it when he decided to return to Asgard again. Unfortunately, their friendship ended up being completely shattered after [[spoiler:Brok was murdered by Odin disguised as Týr, a "Týr" that Atreus unwittingly invited to Sindri's home. The latter in his grief-stricken state blames Atreus for his death to the point of not only rejecting his apology but also denouncing their friendship to the point of telling him to "get the fuck out of his sight". While they fight alongside one another in Ragnarök, the dwarf makes his bitterness to the boy very clear to the point of rebuking his attempts to help him before disappearing to parts unknown (but not before finishing off Odin without asking Atreus or anyone else of their opinions)]].

* ''VideoGame/GodOfWarPS4'': In the Norse saga, Kratos' companion Mimir used to be [[BigBad Odin's]] closest advisor, and the two became good friends. However, over time, Mimir realized just how cruel and manipulative Odin truly was, and Odin didn't appreciate Mimir suddenly gaining sympathy for those he hurt: as such, Odin imprisoned Mimir in a tree and had him tortured every day. Mimir, throughout both games in the saga, talks with utter contempt about Odin and never misses an oppurtunity to mention how evil Odin is. In ''[[VideoGame/GodOfWarRagnarok Ragnarök]]'', Odin is much better at hiding his feelings, but when he talks to or about Mimir, there's nothing short of spite in his voice.

* ''VideoGame/MetalGear2'': Solid Snake and Gray Fox. Not that they didn't still respect each other. There wasn't much ill will at the end of their climactic battle, either.

** In ''VideoGame/{{Deltarune}}'' after beating the BonusBoss, you have the option to tell Seam the shopkeeper about it. Seam will wistfully say that they and [[spoiler:Jevil]] were friends who enjoyed each others' company and played games together, but one day [[spoiler:Jevil was driven mad after being told that the world he resides in is a game]], and Seam had to lock him away for the good of the kingdom. [[spoiler:Jevil]] took this in stride, while how Seam took it is up to player intepretation.

-->'''[[spoiler:Rios]]''': I've changed my mind. I don't want to see that fucker's face again.\\
'''Alpha''': You managed to even make [[spoiler:Rios]] hate you, you evil sack of shit.

-->[[spoiler:'''Vergil''': ''[after defeat]'' I loved you, brother...]]

-->[[spoiler:'''Zeke:''' [[MeaningfulEcho Half as long...]]\\

--->'''James Vega''': You know the Commander?\\
'''Virmire Survivor''': [[BrokenPedestal I used to.]]

* In ''VideoGame/{{Portal 2}}'', [[spoiler:Wheatley]] attempts to [[ExploitedTrope exploit]] this to make Chell stop running away from his DeathTrap. Being [[spoiler:Wheatley]], it's not very subtle.
--> "Aw. Just thinking back to the old days when we were friends. Good old friends. Not enemies. And I'd say something like 'come back', and you'd be like 'no problem!' And you'd come back. What happened to those days?"

** ''VideoGame/{{Persona4}}'':

* ''VideoGame/{{Persona 3}}'': Happened to Akihiko/Mitsuru and Shinjiro, though without the FaceHeelTurn. The three were the founding members of SEES, but after an incident in which Shinjiro's Persona went out of control, [[spoiler:killing Ken's mother]], Shinjiro distanced himself from the group, resulting in many bitter quarrels with Akihiko. Later in the game, Shinjiro rejoins the team, but things remain tense between him and Akihiko until [[spoiler:Shinjiro dies protecting Ken]].
** ''[[VideoGame/{{Persona4}} Persona 4 Golden]]'': Under the right conditions, namely [[spoiler:getting the Jester Social Link to Rank 6 before November 5 and then confronting the killer alone]], you can invoke this on the killer when their identity is revealed. The killer calls you out on your naivete and threatens to shoot you.
** Also from the fourth game, there's Chie's friendship with Takeshi, whom you meet on Chie's Social Link. Chie and Takeshi have known each other a long time, but Chie is somewhat uncomfortable with Takeshi's infatuation with Chie's best friend, Yukiko, and it's clear that Chie and Takeshi are more distant than they used to be. Later on in the link, though, during an argument over Takeshi's refusal to admit that he ran away from a gang of bullies, Takeshi notices how Yukiko has changed and become more openly cheerful, laughing at the strangest things, and accuses Chie of causing this. Chie angrily points out that this is Yukiko's real personality, and the two part on bad terms, never to be seen together again.

** In the [[VideoGame/KnightsOfTheOldRepublicIITheSithLords sequel]], it is heavily implied that Atris and the [[PlayerCharacter Exile]] (Meetra Surik in canon) used to be good friends, with Atris even looking upon Surik as her personal hero (despite outranking her) and everything a Jedi should be. Surik's decision to defy the orders of the Council and join the Mandalorian Wars out of compassion for those suffering and utter conviction afterwards that she did the right thing shattered Atris' view of her and she began to intensely hate her former friend.

** In his arcade ending from ''VideoGame/MortalKombatX'', [[spoiler:Bo'Rai Cho ends his friendship with Raiden after learning about [[FallenHero the corrupted god's]] unprovoked attack on Outworld, training Outworld warriors to oppose him.]]

* In ''[[VideoGame/KittyPowersMatchmaker Love Life']]', if a villager misses their scheduled hangout with their friends or insults them while gossiping, they'll earn a Friend Strike, and getting three of them will make them enemies unless you salvage their friendship [[MakesJustAsMuchSenseInContext by playing pinball.]] The proposing villager being caught having an affair during a RelationshipUpgrade will also make their secret lover enemies.

* Kazuma Kiryu and his sworn brother Akira Nishkiyama from the ''VideoGame/{{Yakuza}}'' series; as shown in ''Yakuza 0'', Kiryu and Nishiki were BashBrothers when they were first starting out, the two of them fighting together against the Dojima family despite almost insurmountable odds. Then Nishiki killed Sohei Dojima in the opening scenes of ''Yakuza'', with Kiryu taking the fall so Nishiki could continue to support his ill younger sister. Unfortunately, Nishiki suffered a TraumaCongaLine soon after and without Kiryu to keep him level he became more and more ambitious, and by the time they meet again after Kiryu makes parole Nishiki is not above trying to frame and/or assassinate Kiryu if it means he'll continue to rise through the ranks of the Tojo Clan.

* In ''VideoGame/StarwarsKnightsOfTheOldRepublic'', Revan and Malak used to be friends, till they were corrupted by the [[spoiler:Sith Emperor]]. Then the dark side of the force did the rest.

* ''VideoGame/TheElderScrollsIIIMorrowind'': Nerevar, Dagoth Ur, Dumac, Almalexia, Sotha Sil, and Vivec were once friends who fought together in the rebellion against the Nords occupying Resdayn. When the War of the First Council happened, they were torn apart by what to do with Kagrenac's Tools, with the Tribunal ascending to godhood, Dagoth Ur seemingly destroyed, and Nerevar murdered by his friends. When the Nerevarine, reincarnation of Nerevar, confronts Dagoth Ur, he brings up their friendship saying "Come, Nerevar. Friend or traitor, come.", "Dagoth Ur welcomes you, Nerevar, my old friend." and [[spoiler:"I thought we might once again be friends... comrades... brothers in arms."]]
* ''VideoGame/TheElderScrollsVSkyrim'': Ulfric Stormcloak, Galmar Stone-Fist, and Legate Rikke were once friends who fought together in the war against the Aldmeri Dominion. In Skyrim's Civil War, however, Ulfric and Galmar lead the Stormcloak rebellion and Rikke works with the Imperial General Tullius to put said rebellion down. There is no happy ending for them. If the Stormcloaks win, Ulfric and Galmar all but plead Rikke to surrender so they won't have to kill her, but [[LastStand she refuses]]. If the Imperials win, Rikke still hopes to the bitter end that Ulfric will see reason and surrender, but is forced to fight him and Galmar to the death when he also refuses.
** Paarthurnax, in the ending of the main quest, grieves for Alduin with words very much like this.
