->''You know, it's a little disturbing how little I've seen the aliens fight the soldiers and soldiers fight the aliens. Everyone's just trying to kill me and unarmed civilians. It's like they think that if they kill me all their problems will automatically be solved.''
-->--- '''[[VideoGame/HalfLife Gordon Freeman]]''', ''FreemansMind''

You're playing a multi-player game with one player and several computer opponents, set to free-for-all. You'll probably see the AI players fighting each other quite a bit, right?


In many games which feature AI players, those players usually gang up on the human player(s). Even if it would be to their advantage to attack each other, they'll go for the human player every time. Can be an effect of SpitefulAI

This is usually done to discourage the player from hiding and letting the computer players weaken each other and swoop in for easy kills. Also, in a deathmatch that scores by kills made, having the AI gang up on you is preferable to them staying away from you because you are in the lead so the AI players can catch up.

Naturally enough, this trope can also be [[InvertedTrope inverted]] when multiple humans play in a free-for-all and gang up on the AI before dealing with each other.

[[folder:Action Game]]
* The ''VideoGame/{{Bakugan}}'' game on the DS. In a battle royal, any time your bakugan is in combat, expect to see two of the following on the opposing side of the power meter: 2P, 3P, 4P. They NEVER aid you, and they do nothing when two computers are battling. you can attempt to return the favor, though, by aiding someone who has fewer captured gate cards to stall for turns.
* ''VideoGame/{{Bomberman}} 64: The Second Attack!'' has Battle Mode AI that HATES human players, especially in the Challenges. The ones that get killed off and return as ghosts almost ALWAYS chase a human player if they're alive. This gets very annoying when two of them take turns grabbing you, forcing you to drop bombs, and holding you near those bombs, inevitably long enough for you to die because you can't escape.
* In ''StarWarsBountyHunter'', there is a level in which the player has to escape from a prison during a riot. Theoretically, the guards and prisoners are supposed to be fighting each other, but in reality, they all gang up on the player for some reason.
** [[JustifiedTrope Possibly justified]] because Jango, the eponymous Bounty Hunter and Player Character, is [[HoistByHisOwnPetard the one who]] [[FridgeBrilliance put them there.]]
* The AI in ''VideoGame/{{LEGO Adaptation Game}}s'' mostly only shoots at the human-controlled character(s), even if there's friendly AI-controlled characters shooting at them. [[ItsUpToYou It doesn't help that the human-controlled characters are the only ones that can deal or take damage.]]

[[folder:Action RPG]]
* In all of the ''VideoGame/MonsterHunter'' games, your job is (usually) to take out a large wyvern or something similar. However, there are often normally peaceful animals (such as pig-like things) that will, should they be attacked by the boss monster (or even hit by a gust of wind), turn on the players, charging into them and knocking them down.
** Although, in ''Tri'' at least, you can occasionally see an attacked peaceful monster turn on the wyvern instead of the player, but if it leaves the range then the monster will turn on you instead.
** One mission in ''4 Ultimate'' tasks the player with hunting a Gyceperos and a Nerscylla. Both will readily gang up on you even though Nerscyllas generally not only kill and eat Gyceperoses, but ''wear their skins'' too.
* In ''MarvelUltimateAlliance 2'', all the enemies will attack the guy that you're controlling. Combine this with the fact that you can block indefinitely without taking damage, and the [[AIBreaker game gets a lot easier]].
* For some reason in ''VideoGame/TalesOfGraces'', the CPU will focus on whoever the player is controlling. Play as Pascal and try to use her spells? They'll run right for her and interrupt them, ignoring Asbel and Hubert running around wreaking havoc. Play as Sophie or Cheria? every time you try to heal they go right for you. Try to play as Richard and go as far as you can from the enemies to cast Holy Lance? Then (at least one) will run ''right on over'' and interrupt you.
* Most bosses in the ''VideoGame/KingdomHearts'' series focus entirely on you instead of your party members, and the ones that don't still heavily favor attacking you over them, to the point where you have to ignore them completely for a while to get them to attack your allies for a few seconds. Doesn't help when if you get KO'd, no matter who is still up, [[WeCannotGoOnWithoutYou YOU LOSE BY DEFAULT!]]
** By default, the enemies (both bosses and standard enemies) in the ''Kingdom Hearts'' games were programmed to always go after the player, but if your allies manage to make them flinch, the enemies will get sidetracked and draw their attention to them, instead. This happens all the time with standard enemies, but not so much with bosses, as the attacks of allies '''''[[MillionToOneChance rarely]]''''' cause them to flinch. Anyway, if an ally is able to make an enemy flinch, a single attempt at attacking your ally will be made. Whether it fails or succeeds, the enemy will draw its attention ''back to you''.

[[folder:Board Game]]
* Electronic Board games often do this when they're not [[TheComputerIsACheatingBastard slanting dice rolls]]. They'll often slant the dice rolls for the human player(s) but never versus themselves. This is especially true for ''Monopoly'' games, which often have CPU-players somehow get the best rolls so they manage to dodge all your squares or even go to jail if it means avoiding that line of hotels. If you're playing versus three [=CPUs=], they'll basically try very hard to make ''you'' lose, but not each other.

[[folder:Casual Game]]
* ''MS Hearts'', a card game that comes default on many MicrosoftWindows systems. The point of Hearts is for four players to compete in a series of games until someone gets over 100 points, at which time the player with the lowest score wins. One would think it would be every man or woman for themselves but the AI players seem to pick one of themselves to be your rival, with the other two acting as sacrificial lambs, soaking up as many points as possible to help the one win.

[[folder:Eastern RPG]]
* It wouldn't be much of a stretch to state that every turn-based RPG does this, as they force groups of enemies into the same encounter against the player, even if they would not have a reason to even consider it. Such examples as pairings of [[CarnivoreConfusion predator and prey]], [[ElementalEmbodiment elementals of opposed elements]], or even [[EnemyMine soldiers of opposed armies]].
* Notably averted, however, in ''VideoGame/FinalFantasyXIII'', in which you'll often come across two or more enemies fighting each other. Usually, neither side will attack you until you either attack them first or the other side is killed.
* Also averted in Horde Battles in ''VideoGame/PokemonXAndY''. If Zangoose and Seviper appear in the same horde, they will attack each other, [[SlidingScaleOfGameplayAndStoryIntegration since they are sworn enemies]]. Similarly, one possible horde consists of four Durant and their predator, a Heatmor, who will attack the Durant first.

[[folder:Fighting Game]]
* In ''VideoGame/SuperSmashBros'':
** The final match before Master Hand in ''Brawl'' is a Battle Royal… except for the fact that it's not. CPU characters focus on beating ''you'', instead of each other. This is even more evident with the Dragoon and Smash Ball: the CPU opponent getting it always focuses on a player.
** In fact, this seems to be the case in a regular free-for-all match. There will always be at least one guy who will stalk you no matter how much you try to distance yourself and when they do, it attracts attention from the other AI players, thus you get caught in the "[[IncrediblyLamePun brawl]]." Nor is it limited to the AI's use of items. If you aren't there to hit, the CPU players tend to just jump around and occasionally take a pot shot at each other. Also, if you hide behind a wall in a custom stage, which the [=AIs=] have trouble with, in free-for-all, they will ignore each other and attempt to hit you, even though they ''can't'', or they'll just pace back and forth together.
** Most glaringly, a computer controlled ''ally'' will [[ArtificialStupidity occasionally target]] ''you'' with a Dragoon (which [[FriendlyFireproof can't hurt you]]) or with a Bob-omb (which can), or even worse use their Final Smash on you when they cannot find a hostile AI (such as if they were KO'd and still on the respawn platform).
** In a team battle where you're partnered-up with one or two [=AI=] allies and the remaining [=AI=] opponent(s) grab a Smash Ball, they will completely ignore your allies and try to hit YOU with their Final Smash, even if it'd also benefit them to hit your allies!
** If ''Brawl'' didn't make it obvious that it hates humans, you can occasionally see the CPU players chuckle at you by taunting right after you get KO'd… ''by another CPU.''
** It's egregious enough that CPU players will self-destruct at the chance to get closer to the player. This can be seen by making the human spawn on a platform the AI's can't reach. In this case they'll all run and try to get under or over the player's platform even if it costed them stocks in the attempt.
** The AI has also been known to do things like use unusual amounts of teamwork. If an AI grabs a Smash Ball and has a Final Smash that covers a large area of the screen in a particular direction (Samus, Mario, Ganondorf), another computer will sometimes grab and hold you to make sure you can't get out of its way.
** The trophy tussle events in ''Melee'' were absolutely horrible. One CPU camped out in a set location, while the other two fought the player. When the player goes, they wouldn't bother attacking each other. Really, those were more team battles with Friendly Fire enabled.
** In ''Melee'', when the battle starts the AI will attack each other as much as the human. But the moment a human player gets a lead in KOs or stock, the AI will turn their attention to that person and chase him/her everywhere, hardly attacking each other.
** Mercifully, [[DownplayedTrope the fourth game seems to have eased up on this]]: CPU's still prefer to hit you, but will usually use it on someone else if you aren't around. Of course, there are also observed cases in team battles, where the player's AI partner gets the Smash Ball and then will simply hold onto it, refusing to use it on anybody.
* ''VideoGame/GuiltyGear'' Isuka can have up to four players fighting at the same time. However, if it's a free-for-all, the CPU players will almost always attack you rather than each other.
* In ''VideoGame/WWEAllStars'', in a Triple Threat or 4-Man match, the AI will almost always zero in on you, but it's still good enough to fight each other if it kicked your ass or the match just started. But there are still instances where all computer characters relentlessly walk towards you for ''minutes''.
** Tornado Tag Matches avert this, though. More often than not, one of the AIs will focus on you and the other on your partner, never any ganging up.

[[folder:First Person Shooter]]
* In ''VideoGame/CallOfDuty:'' ''World at War'' as well as the ''VideoGame/ModernWarfare'' series on [[IdiosyncraticDifficultyLevels Veteran difficulty]], the AI will do what it takes to kill you, no matter if they have to aim for you as soon as you're seen, how many allies you've got next to you, [[SpamAttack or how many grenades they've thrown has failed to]].
** ''Modern Warfare 2'' also has a specific instance of this, where you're told to let two armies battle each other, but if you move faster than a crawl, they'll drop the ongoing battle and shoot at you.
* Likewise, the A.I. in ''VideoGame/MedalOfHonor: Airborne'' would auto-target you the moment you popped out of cover, regardless of how many allies you had running around next to you.
* ''VideoGame/{{Resistance}} 2'' has this in spades, particularly during Grim swarms. Thankfully the ally AI is competent enough to continue shooting at the freaks.
** Happens in the first game too. Enemies will go for you unless there's a much closer target or they're already engaged. One easy place to observe this is the first encounter with Gray Jacks. Kill the first one quickly to save the soldier it's attacking -- you'll then find that the remaining Gray Jacks prefer you to him by a wide margin.
* In the ''Franchise/{{Halo}}'' games:
** The Covenant will always target ''you'' in favor of the various marines. Granted, this does make sense if you're surrounded by infantry, as you're a {{supersoldier}} and thus are a greater threat than the marines. This gets a bit more ridiculous when the Scarabs target you, instead of the tanks that are shooting it. It's even more ridiculous if you have reasonable cover, and itty bitty you would be much harder to see as opposed to the big ass tank that's not making any effort to hide, and they still go for you.
*** This becomes even more annoying - because it's blatantly obvious - in ''VideoGame/HaloReach'' where your NPC team mates are Spartans just as you are. You're not even the team leader but merely the latest addition to the squad - a replacement, no less. Yet the Covenant act (and aim) as if you're the only viable target on the battlefield.
** When the player runs into the Flood, things get hairy because they ''also'' ignore everything else and try to turn Master Chief into metallic paste. However, not initially entering their vision range gives the player a nice rare opportunity to sit back, grab a snack and watch The Covenant and Flood duke it out for a few minutes.
* ''VideoGame/{{Bulletstorm}}'' is a pretty egregious example, as enemies will almost never go after your teammates. Even if you're fairly far away and in cover, and your teammates are standing out in the open firing, the enemies will still aim their shots at you.
* ''VideoGame/TimeSplitters'' is actually good about avoiding this. There are plenty of times when you can see the AI "distracted" by another target, and as expected, once you start attacking them, they start shifting their attention to you.
* Completely averted in the ''VideoGame/{{STALKER}}'' series, in which members of various factions will fight each other and dangerous wildlife whether you are present or not, and your arrival doesn't alter their priorities at all until you get involved. In the first game there is even an arena where the final battle is a 'free for all'… but the other combatants all start near each other and far from you, causing them to kill or severely wound each other before you can even make it to them.
* In ''Borderlands'', skags will attack just about anything human, including your enemies. However, if you get close to them or shoot them, it's very likely they'll drop everything and come after you.
** This trend continues in ''Borderlands 2''. In fact, one enemy type, known as Goliaths, will kill everything in a psychotic rage if you shoot its mask/helmet off. This is subtly recommended by the game, since the experience points for every enemy a Raging Goliath kills is tripled and then added to the Goliath's experience points, which you then get when you kill the Goliath. Only problem is, he's healed to full every time he makes a kill, and can one-shot you with his ShockwaveStomp attack if you don't have a considerable advantage (in health, shields, and/or weaponry) over him.
* Normally avoided in ''{{VideoGame/Doom}}'' and other [[GameEngine Doom-engine]] games, due to [[SetAMookToKillAMook monster infighting]]. Some complications go towards this trope though, as lost souls will only make a single attack on on an enemy that hit it before turning their attention back to the player. ([[ArtificialStupidity which still leaves that enemy angry at the lost soul]]). And in ''Doom 2'', enemies will ignore any damage taken from the [[DemonicSpider arch-vile]], though arch-viles will kill (and then resurrect) any enemy that hits them by mistake.
* A more blatant example would be in ''Goldeneye 007'' for the N64. In the second run on the Bunker area, the game introduces you to your fellow prisoner Natalya whom you can free by killing the prison guard and taking the cell key. The troops in the Bunker will be absolutely focused on you and no one but you, completely ignoring the other prisoner that is following you around. She can get damaged, but sometimes you can never tell since in most cases she never even flinches from stray shots. Not that it matters since they're all dead set on you. In fact, if you get to the main room and not take out the guards watching over the computer, they will act if Natayla isn't there at all as she makes her approach to it and turns it on.

[[folder:Massively Multiplayer Online Game]]
* This occurs all the time in ''VideoGame/CityOfHeroes''. If you interrupt a battle between two AI groups that should by all means be mortal enemies, not only will they immediately team up to defeat you but they will also suddenly be the best of friends and not kill each other while you're coming back from the hospital.
* Hostile creatures in ''VideoGame/WorldOfWarcraft'' actually treat you and their current opponent the same way, basing it on the Threat system, though it's possible AI threat is reduced. It's just that the player is usually much more effective at dealing damage than the creatures, so you quickly exceed the threat posed by their other enemies. If one of them is particularly damaged it's impossible to draw threat from them before the damage kills them (barring healing threat, high threat moves, and taunts.)
** In the ''Cataclysm'' expansion, there are a number of quests where creatures spawn into perpetual battle with other creatures or [=NPCs=], which you are then required to kill. In many of these cases, they can whale on each other for hours but never deplete each others' health bars, but as soon as you deal a single point of damage, they come right for you.
*** Even worse, though, is when they don't. If you kill a Restless Soldier or Restless Infantry ghost before hitting his opponent, the opponent will suddenly heal to full health -- even if he's been below half health since he spawned.
* Similar to the above example, ''GuildWars''. You might often see enemies fighting each other. But the second you come into range or lay a finger on one of them, they immediately drop all grudges they had against each other and attack your team.
* ''VideoGame/BattlestarGalacticaOnline''. Your enemy and the unaligned drones have no love for each other, but that doesn't stop them from calling an informal truce to go after you if you blunder into the way.
* In ''VideoGame/TheLordOfTheRingsOnline'', creatures which are mortal enemies (such as deer and local deer hunters) will both gang up on you. This happens most often in Dourhand dwarf regions, where animated combat between invading [[BigfootSasquatchAndYeti Yeti-like creatures]] and Dourhand dwarves will end on your arrival, so that both of them can attack you.
* [[AvertedTrope Averted]] in ''VideoGame/{{Firefall}}'' : the aggressive wildlife, bandits/Ophanim and Chosen will all fight each other. Humanoid targets will also stop attacking players to fight back against wildlife that wandered by. This is even [[LampshadedTrope lampshaded]] in an early mission where you drop pheromones in a bandit camp. There's a mission where you need to [[EnemyMine bolster the bandit's morale]] against the [[BigBad Chosen]]. Later on, the Chosen will deploy mining thumpers and be completely swarmed by angry wildlife, just like it would be for players.

[[folder:Party Game]]
* Attempting to complete the game and get everything in the single-player modes of ''VideoGame/CrashBash'' got particularly obnoxious in many stages. In a stage like 'Ballistix' where a ball simply needs to be hit into a goal to register a win, the AI will simply prioritize protecting their goal, much like the player will. In 'Pogo Pandemonium', however, you can be absolutely sure that you will be their only target and their most common target. The AI even seems to team up in a very specific: One character will focus on getting points. They will take as much area as they can in any way they can, even if doing so will be risky. The second character will try to take items from you whenever possible, making it hard for you to fight back. The third character will work in conjunction with the second to try to keep you away from character #1, and use items to stop you whenever they can. Play enough times in a row, and you'll notice that the #1 spot will almost always go to the first character. Coupled with the fact that you'll need to win each minigame three times ''in a row'' for 201% completion, and you'll almost certainly be throwing controllers.

[[folder:Platform Game]]
* In ''VideoGame/ShadowTheHedgehog'', aliens have invaded and human soldiers are apparently trying to fight them off. And the aliens you would be expecting to be killing off the soldiers. Except they don't; all they do is gang up and fire rapidly at YOU, even when you're on their team. Way to persuade Shadow to save humanity, G.U.N.
** Justified in that G.U.N. has orders to bring him in dead or alive. And in the only stage before they get those orders, they actually DO ignore Shadow. Black Doom, however, given he is trying to get Shadow on his side, has no such excuse.
* ''VideoGame/ConkersBadFurDay'''s mini-games can have this on its bad days. Although it is probably unintentional in mini-games other than ones based around killing free-for-alls (such as the multi), mini-games that feature teams which can include computer and player characters, including War (both Color and Total), Heist and Raptor, there are sometimes incidents computer-controlled characters can gang up and attack the player while ignoring each other, and other times even the computers who were supposed to be on your team can join the witch hunt as well (this can happen regardless of how smart/inbred you set their AI level to).
** In Color!War, it can play this trope even more straight. Normally, if you shoot down at least 4 of your allies for whatever reason, your entire party will brand you as a traitor and start opening fire on you on-sight while the opposing party will no longer harm you (this can happen regardless of if you were initially a Squirrel or a Tediz). Because you're still on your side despite being a traitor, however, you can ''still'' take your opponent's flag, in which case now ''both'' sides will be after your ass (yes, even while you're carrying your enemy's flag, your own party will still recognize you as a traitor and try to kill you for attempting to give them a point.)
* Averted in ''VideoGame/{{Iji}}'', where the two alien races, Tasen and Komato, are hardcoded to prioritize shooting the other race over shooting you.
* In ''Videogame/TokyoJungle'', computer-controlled animals will sometimes go after each other, but are just as likely to band together to attack ''you''. This can reach absurd levels, such as a tiger, a bear, a pack of hyenas, and a crocodile all chasing after a tiny house cat while utterly ignoring each other.
* The ''VideoGame/{{Touhou}}'' fan-game ''Mystical Chain'' has the second boss battle feature two eternal-rivals who could care less about your characters who are caught in their (perfectly countered) crossfire.

[[folder:Racing Game]]
* ''Destruction Derby 2'' for the PC was notorious for this. In the Total Destruction mode, from the moment the game started, every single AI car would immediately smash ''your'' car, without even attempting to play against each other.
* ''VideoGame/MarioKart'' is a fine example on the higher difficulties of this, where coincidentally every single item seems to hit just you.
** This also applies in team VS matches, where your own AI teammates seem to save their items solely to attack ''you'', with no effect. They'll even ram into you when you have shells circling your kart in order to waste them, and will also often try to ram you off the track.
** In VideoGame/MarioKart DS, this part of team VS matches was even more common, due to the fact the team aspect simply added up the points of characters on said team, not disable friendly fire. Hence it's more like a free for all than a team game.
** In ''VideoGame/MarioKart Double Dash!!'', every AI player on the track will get items, and use them on you. And only you. They never even try to attack each other.
** There have been recorded cases of enemy AI firing Red Shells ''backwards towards you'' in games where they only home in going forward, they're in striking range of the place ahead, and it could mean the difference between 1st and 2nd.
** Throughout the series, the computer opponents are programmed to finish the races in the same order (selected at the start) so that one racer will accumulate the most points, making it the racer the player has to beat. If the player can take out the leader at the end of a race and cause them to lose their place in the standings, that racer will fall back and let the new leader win the races in order to beat the player.
** In ''Mario Kart 7'', the CPU racers are known to waste their items solely to get you instead of using them for something that could actually help them win. One example is on N64 Luigi Raceway, where you can hop onto an upper path with booster panels, a path the CPU almost never takes, even on the higher difficulty settings. The CPU has been known to throw Bob-ombs up there to blow up you and ''only'' you.
** The team battle mode of ''Mario Kart 8'' is particularly frightening in that you can't go near ''anyone''. Your team members will almost certainly throw boomerangs and shells in your direction when you pass by them and there's no way to know when they will or won't decide to be a traitor. Ironically, however, this may be intentional, as it's sometimes difficult to tell who's on your team. The only thing that differentiates the two are the colors of the balloons which you almost certainly won't be able to see from a long distance, thus making a frightening ordeal when you see a racer approaching and you have no idea whether or not it's an opponent who you should be trying to line up an attack with, or a partner that you should avoiding so as not to get in their way. Chances are the human players will be accidentally hitting their partners just as often as the AI.
*** The Team Race mode is also pretty nasty about this. The AI seem to either not notice or not care about the team race function and will simply attack whatever racers get near them, basically treating it as a normal race.
* The AI-controlled opponents in ''[[TwistedMetal Twisted Metal 2]]'' would rarely, if ever, attack each other, being almost exclusively concerned with attacking the player.
** The first game is guilty of this as well. They'll drive around aimlessly, but if you come into sight they'll usually drop everything and make a beeline straight towards you. You can actually get your AI opponents to drop into one of the lower areas in the final level and then watch them just drive around in circles and occasionally run into each other, not opening fire again until one of them figures out how to get back up to where you are.
* In ''VideoGame/NeedForSpeedMostWanted'', even if the police started chasing you in the middle of a race they will never, we repeat: NEVER give even the slightest of darns about pursuing the other racers during the chase afterwards. They get off scot-free while you take all the heat.
* In ''VideoGame/JakXCombatRacing'' all the A.I. racers seem to be zeroed in on you (including your ''team mates''), heat seeking missiles are targeted at you 90% of the time, and you will most likely find yourself at the far last place most of the time.
* The AI in ''ForzaMotorsport 3'' will drive in tandem to prevent you from passing and gang-rape you when you try to pass.
* The final race of the first ''SnowboardKids'' game is particularly brutal as a solo race; not only are you against a [[FinalBoss ninja with maxed-out stats]], [[SpitefulAI the other 2 AI players will endeavor to stay behind you]] ''at all costs'', just to make sure they can keep hitting you with forward-firing weapons and let Shinobin coast to victory. They will do this shamelessly, even if you are going comedically slowly just to make it more transparent.

[[folder:Real Time Strategy]]
* Happens in ''StarCraft'' if you're fighting against multiple computer opponents without explicitly setting teams beforehand. They actually ally each other and proceed to throw endless waves of doom down your throat.
** One particular level of ''[[ExpansionPack Brood War]]'' [[AvertedTrope averted]] this. It's the simplest level in the entire game, because the computer-run Protoss and Zerg forces are too busy fighting each other to launch that many attacks against the player-run Terrans. The fact that this is a very dull and unchallenging level probably highlights the reason why this trope exists.
** This is actually somewhat pragmatically done in the original Terran Campaign. The second to last level involves a three-way between the Terrans, Zerg, and Protoss, in which you, the Terrans, will lose if the Zerg lose even one building, even if it's an easily replaceable defense colony. The Protoss and Zerg do not attack each other, in fact, the odd Protoss will actually ''walk through'' the Zerg base to get to you. It's not so irritating though, because the Protoss hardly attack at all (they're down to their bare basics on the tech tree) and it'd be even more of a pain to defend the Zerg bases while they're trying to kill you if the Protoss too were trying to kill them. Sure they suck, but they'd probably get a lucky building kill and screw you over.
** In skirmish mode, setting immutable teams beforehand will have the AI partner up with you, if that's what you set. (They're marginally helpful, but the AI really does not understand teamwork AT ALL.) In "Melee" Mode, it's Humans VS Computers, no exceptions. In "Free For All" Mode, it's every man (or AI) for him/her/itself, and the computers will happily frag each other into oblivion.
** In fact, by default the scenario editor doesn't even let you sort yourself into the same team as an AI player if you don't use triggers.
** In ''VideoGame/StarCraftII'', the AI tends to be more hostile towards human players, at least on the highest setting (Insane). To test this, create a Free-for-All game with 8 Insane AIs on Megaton so that they start very close to each other. They won't start attacking each other until they built a few army units. Now make the same game but replace one of the AIs with a human player. The AIs closest to the human player will immediately send a few workers to attack them while the others will ignore each other until they build army units.
* ''VideoGame/CommandAndConquer'':
** In every game before ''[[VideoGame/CommandAndConquerRedAlert2 Red Alert 2]]'', the AI would gang up on you once you defeated one AI opponent unless you change the "Paranoid" setting in the rules.ini file.
** The "Paranoid" setting in ''[[VideoGame/CommandAndConquerTiberianSun Tiberian Sun]]'' is even more unfair: the only requirement is that an AI opponent be defeated ''at all'', regardless of who defeated them. Even if a player has remained hidden from the AI opponents the whole match, the moment one of them defeats the other, the player will have ion cannons, hunter-killer drones, and multi-missiles raining down on their base.
** ''Red Alert 2'' initially followed this trope as by default, only Battle mode was available in skirmish (ie. all AIs versus the player). A patch added Free for All but it wasn't until the expansion pack that the player could be allied with AIs (in Battle and Team Fortress mode, the latter incorporated special maps designed for team games).
*** Oddly in ''[[VideoGame/CommandAndConquerRedAlert3 Red Alert 3]]'' enemies are more likely to go after you at medium difficulty than at hard difficulty.
* ''VideoGame/{{Homeworld}}'' has a setting for how often the AI players will attack the human player in the skirmish match setup screen. At the extreme ends, they will either always or never attack each other.
* This is the normal behaviour of the AI in ''VideoGame/WarcraftII'' when playing skirmish games. The AI players never attack each other, only you.
* ''VideoGame/WarcraftIII'' takes it even further -- not only will AI players gang up on any humans, but if there are multiple humans, they'll gang up on the ''host'', specifically. There's no gameplay-based reason to do this.
* ''VideoGame/AgeOfEmpiresII'' had this, if you did not lock teams and set the difficulty at Hard or higher, the computer teammates would within 10 minutes all un-ally you all at the same time and then gang up to kill you in some instances.
* The AI's priorities for troop deployments, war declarations, spying, diplomacy and trade can all be edited in ''HeartsOfIron'', at least from the second game onward. This includes parameters for special behaviour toward human players, usually limited to having them deploy more troops on your border because the human player is more of a wildcard as well as better at using his/her army to begin with, but, either with AI files or events, it's entirely possible to invoke this trope [[UpToEleven even up to the point where you're at war with the whole world from day 1 no matter which nation you play.]]
* In the ''VideoGame/TotalWar'' series, particularly ''VideoGame/RomeTotalWar'' with its awful diplomatic system, every single AI faction is scripted to attack the player, no matter the players strength or economy. The only thing it takes into consideration is how much money it has. This is especially blatant if you keep tabs on the diplomatic relations between factions in the game, as sometimes if two factions are at war and you attack one of them, they will end their war, declare an alliance, and attack you.
** ''VideoGame/TotalWarShogun2'' has "Realm Divide," which is essentially this trope incorporated as a legitimate game play mechanic. Basically, once your clan controls about 15 provinces (out of 65,) ''every other clan'' will ally against you. You're given a severe diplomatic penalty, meaning your former allies will abandon you and you'll be unable to establish trade relations, killing your economy. To make matters worse, the clans allied against you will be [[NotPlayingFairWithResources given large stacks of veteran units every turn.]] To add insult to injury, [[TheComputerIsACheatingBastard AI players never trigger Realm Divide]], no matter how many territories they own.
** Also goes for the actual battle AI. Here's a fun experiment: try creating a custom battle with one player faction and several AI factions (that are opposed to each other), preferably on a very large map and watch how AI troops from all parts of the map start attacking the player while completely ignoring all other enemies around them, even if they would be a very easy kill (i.e. French knights riding next to enemy English archers).
* ''VideoGame/SupremeCommander'' does this in Skirmish mode. If you set, for instance, a free-for-all game with you and 3 AI players, they will make the barest show of fighting each other while sending all their heavy units and experimentals in a beeline straight for you.
* ''VideoGame/{{Pikmin}}'': Despite the fact that you're on a planet with its own ecosystem, with a vast range of creatures of all shapes, sizes, and species, the enemies will only ever go after the captains and their Pikmin, despite the fact that it's implied in the first game that Pikmin have been extinct for a long time at that point.

[[folder:Shoot Em Up]]
* Easily used to the player's advantage in ''[[VideoGame/EscapeVelocity EV Nova]]''. Even if the player has a large pile of escorts, enemy ships will put top priority on targeting the player's ship. A player with a smaller, quick ship and a large number of better-armed ships as escorts can simply run in circles around the enemy fleets while the escort ships pound them into submission.

[[folder:Simulation Game]]
* Computer players in ''VideoGame/{{Civilization}}: Revolutions'' never attack each other, so it's always a 4-on-1 game. A standard strategy is for at least 2 rivals to constantly attack you while they leave another alone to pursue a win condition, thus requiring the human to spend valuable resources securing his own borders instead of advancing.
** ''Civilization 4'' also tends to see humans get diplomatically ostracized at a minimum, in part due to a design oversight. The diplomatic model gives relationship penalties if a nation refuses another nation's request or demand for help. The AI is also coded to never offer "impossible" deals to other nations, to avoid racking up needless penalties, but it can't tell in advance if human players will accept or reject any given offer. Therefore, the human players are the only ones who end up with these penalties, while AIs buddy-buddy up and eventually decide to take out the vile nation that refused to give them free handouts or help them in their wars of aggression.
*** Well, navigating diplomacy is part of the strategy. The AIs don't gang up on the player because they're coded to specifically, they gang up on you if you do things that they don't like. It's actually fairly easy to get on AI's good side to the point where they'll declare war on an enemy or give you a technology just because you ask them.
** The setting “Always War” is this trope in its purest form. No, it doesn't mean that everyone is at war with everyone. It just means that everyone is at war with ''you''.
** Civ 5 inverts it on the two easiest difficulties, and plays it straight from Normal upwards. Also, their soldiers will be so advanced over you on the highest difficulties that they'll feel more biased than they really are.
** In Civ 1, there was apparently a flag that when the game reached a certain year (1900 or thereabouts), all AIs would immediately declare war on the human player. Civ 2 had a similar problem where the AIs would eventually all form defensive pacts to "contain your aggression" and would never attack each other.
* When customizing A.I.'s in ''SidMeiersAlphaCentauri'', one option is "Intense Rivalry." The highest difficulty turns this on for every AI faction.
* In ''{{Mechwarrior}}: Mercenaries'', the player can enter an arena style fight that includes up to 8 other AI characters. Any of the AI characters who are near you will ignore other AI characters which quickly results in Gang up on the Human.
* Invoked in VideoGame/{{Touhou}} fangame, ''Sengoku Gensokyo''. During the story mode, all the other factions attack Reimu, and only Reimu, because [[spoiler: Yukari promised rewards to whoever brought her down first.]] In National Mode, everyone attacks each other, much like factions locked in eternal war ''should''.
* Played straight in the ''VideoGame/EscapeVelocity'' series. When demanding tribute from a planet, defense forces will target you to the exclusion of all else. This can lead to bizarre strategies such as the player simply flying in circles in an unarmed fighter while a fleet of destroyer escorts gradually pick off the enemies.

[[folder:Sports Game]]
* This happens in every single multi-man match in ''Wrestling/{{WWE}} Day of Reckoning''. A three or four-way rumble is just a fancy way to say "Handicap Match."
** This was fixed in Day Of Reckoning Two. The computer players only decide to gang up on the human half the time, other times they may just ignore the human most of the match. Even when they gang up on you, they will quickly turn on each other if eliminating you would allow one of them to win.
** By contrast, this trope was far worse in the rather mediocre WWE Wrestlemania X-8. (Seems the CPU was steadily improving)
** ''[[SmackdownVsRaw Smackdown vs Raw 2008]]'' [[AvertedTrope averts]] this by having AI opponents actually attack each other. You can be in a campaign Triple-Threat match between two guys who have been beating on you for the past ''month'', and they'll still be hitting each other just as much as you.
* In some editions of Pro Cycling Manager, the AI decides that the player controlled rider must do all the work during the classics, even when it would have been against the interest of the involved AI controlled teams.

[[folder:Survival Horror]]
* The zombies in ''VideoGame/DeadRising'' seem to prefer Frank to anybody Frank is escorting. Which is probably for the best, gameplay wise, seeing as the player can fight them off. Whereas the people you're escorting are [[ArtificialStupidity barely more intelligent than the zombies themselves]], and are prone to dying.
** Frank himself [[LampshadeHanging lampshades]] this in [[CapcomVsWhatever Ultimate Marvel Vs. Capcom 3]].
* This can get to ridiculous extremes in ''VideoGame/Left4Dead'' and [[VideoGame/Left4Dead2 its sequel]] when it comes to the Special Infected in single player mode. Most of the time, the Specials will all gang up on only you and [[SarcasmMode thanks]] to the sequel's dumbed down survivor AI reaction times, expect many restarts.
** When all human controlled survivors are killed in VS mode, the round ends, despite any survivor bots alive. Players on the infected team who know of this will focus their attacks only on the human players to end the match as quickly as possible.
** The inverse can also be a viable tactic. While the survivor bots will never fail to try to save another survivor, the humans players sometimes will. Further, the AI Director won't spawn more than three of the Special Infected that can pounce survivors (Hunter, Smoker, Charger, Jockey) at any one time. Thus if there's only one bot survivor it can be worthwhile to kill them first to make it easier to get the three humans, either all at once or one at a time while the others are distracted.

[[folder:Third Person Shooter]]
* In ''StarWarsBattlefront II'' almost as soon as the player manages to get a shot out, every enemy, regardless of how far away they are, will ignore all other threats and attack the player.
** This is actually the primary reason all AI teams usually fail. Whenever you waltz in all the enemies focus on eliminating you, which often leads them to either being bested by you or killed by your team mates. Even in competitive play you can still use this to your advantage because of the large number of computer players inherent in the game. If you yourself gang up on any enemy human, your friendly AIs will still have a big advantage over your opponents distracted AIs.
* The first ''GearsOfWar'' was really bad about this; all enemy A.I. units would instantly auto-target you the moment you popped out of cover to shoot, completely ignoring your A.I. teammates even if they had been locked in combat just moments before. This was particularly noticeable on [[HarderThanHard Insane]] difficulty, and made flanking and ambushing much less effective despite the game supposedly being centered around such tactics. Thankfully this was removed in later games, creating a more natural battle flow.
* ''VideoGame/KidIcarusUprising'' is a bit on-and-off about this. Underworlders and Forces of Nature are at each other all the time, especially in the air battles, and when the [[spoiler:Aurum]] show up, the fight instantly targets them. However, it is also completely possible for you to be attacked by, say, a Skuttler and a Rezda at the same time, without them doing anything to interfere with each other. It seems to be quite random.

[[folder:Turn Based Strategy]]
* In ''VideoGame/FireEmblemAwakening'', you can do "Paralogues," which are auxiliary stories to the main narrative. In one, you happen upon two rival bands of mercenaries who've been feuding over an area for a while before the Shepherds, that is, your party, arrives. You're given the option of allying yourselves with either faction, or neither, and if you [[TakeAThirdOption pick the third option]], both teams forget their enemity and will fight side by side if it means killing you and your friends.
* The popular Flash strategy game ''[[http://www.gamedesign.jp/flash/dice/dice.html Dice Wars]]'' has an interesting variation. The computer players usually attack any side indiscriminately. But if one side, human or computer, gains a clear advantage the rest of the computer players will all gang up on that side. A cunning player can exploit this to get zones without worrying about retaliation, but if you do too well then the others will inevitably gang up on you.
* In the first ''VideoGame/HeroesOfMightAndMagic'', you could set all the computer players (since every map had four players) to "King of the Hill", which would cause this. No other entry in the games had it since.
** However, ''Heroes of Might and Magic V'' had AI behavior that ends up doing the same. While it's FFA, none of the AI players bothers to defend their castle against other AI players, usually taking their entire force to attack another player (more often than not, the human). Sooner or later, it would be you against one single AI who has taken over everyone else. Assuming you managed to survive the suicide attacks coming at you, that is.
* While it may seem that SpaceEmpires suffers from this trope, it only ''sort-of'' follows it; enemies are just as likely to go to war (or already be at war when you find them) with each other as they are with you, not to mention make alliances, all dependent on their [[AIisacrapshoot diplomatic personalities.]] If however you're expanding out hugely, and at all sides at once, it may SEEM like they're all targeting you, but that's only because you're the first alien species any of them have met and they ''don't have any other targets yet.''
** Also, the AI doesn't do a very good job of estimating how dangerous a human player is; they can overestimate you if you do a lot of cheap research or underestimate you if you don't build as many ships and units. Either can lead to AI players thinking they should wipe you out before resolving their own differences.
** Finally, there's actually a hidden feature called the [[BigBad Mega Evil Empire]]: if any empire gets far enough past the second-ranking empire, everyone will gang up on them, declaring war on them and refusing all treaties. While active for both players and AIs, the AI can typically push their empire to a far greater margin of superiority (by default in SEIV, 250% of the second-ranking empire's score, compared to the human's 170%) before the entire galaxy turns on them. Also, it's not like you'll often see an AI run into this feature on their own in either case, given that [[ArtificialStupidity most experienced players can run circles around the AI]] without [[TheComputerIsACheatingBastard giving it some extra bonuses]].
** There is an actual "all AI against all Human" setting, but it's disabled by default.

[[folder:Western RPG]]
* In ''LordOfTheRings Conquest'', [[BossFight bosses]] ''will'' track you down, no matter what. Especially annoying is Saruman, who'll just stand around in his tower waiting for you to come up and get trampled, and maybe chase you for two feet.
* A minor version occurs in ''VideoGame/MountAndBlade''. In the arena melees, AI opponents will usually fight each other just as much as they fight you... but the moment you drop, they stop fighting and ''cheer''. It's like, "okay, he's out, we can stop pretending to be hostile now." This has been fixed in newer versions of the game.
** Also in arena fights, once you start winning the remaining enemies will often cease fighting altogether just to charge you, and ignore any opportunity to hit each other.
** There are two actually legitimate reason for this to occur in Warband; Kings and their Vassals will, in times of war, loot any weak enemy territory and ambush a force they have a numerical advantage over. A player meets this criteria when first joining a faction and getting a burnt-out fief in exchange. Secondly, they will prioritize going after the fiefs of enemies who have defeated them first; a player who has been hanging around in Calradia for about 200 days will have made plenty of enemies by then.
* In ''Franchise/MassEffect'', the likelihood of any enemies targeting your squadmates instead of you seems to be inversely related to the difficulty level. On Insanity, enemies will ''never'' target your squad, ''only'' you. Even if they're getting beaten to a pulp by your allies directly in front of them and you're behind cover halfway across the battlefield. Which rarely happens on higher difficulties, however - as this trait was introduced in the [[VideoGame/MassEffect2 second game]] and kept for the [[VideoGame/MassEffect3 third]], where there are ''specific stats'' governing how much weaker [[PlayerParty henchmen]] are than [[PlayerCharacter players]]. [[DangerouslyGenreSavvy Combine this]] with [[WeCannotGoOnWithoutYou the fact that Shepard hitting 0 HP]] means GameOver. Despite this, ''Mass Effect 3'' has an [[ArtificialBrilliance improved aggro system]] that ''will'' take down squadmates who are noticably bigger threats to enemy positions than Shepard.
** This can be [[ExploitedTrope exploited]] in ''VideoGame/MassEffect2'' by Infiltrators using [[InvisibilityCloak Tactical Cloak]] and some clever squad placement, especially against slow but powerful enemies like the [[BossInMookClothing Praetorian]]. Not so much in [[VideoGame/MassEffect3 3]]'s single player, where the enemy will ''hear'' Shepard's footsteps, and also feel him/her brushing up against them. The same thing does happen in [[CoOpMultiplayer multiplayer]], but the enemy are more likely to home in on the [[WeNeedADistraction fully visible enemy pelting them with bullets]], as they're also a PlayerCharacter, just like you. Applies fully when the [[spoiler: [[MightyGlacier Geth Juggernaut]]]] hits the field, as he has abilities that increase his aggro beyond even that of Shepard's - forcing enemies to home in on the one character in the game [[NoSell immune to]] [[OneHitKill sync-kills]].
** Invoked by [[BigBad Harbinger]]. Once he [[DemonicSpider 'assumes Control']], he will head right for you, regardless of anything put in his way.
* In ''VideoGame/TheElderScrollsVSkyrim'', you can see people attacking monsters (or even each other) but if you stay out of the way, they actually ''will'' kill each other and let you attack the survivor. Other times, they'll forget whatever they had and attack ''you''. There have also been reports of dragons [[GenreSavvy luring players into aggro radius of monsters]] and letting them cherry-tap the player.
** This is particularly noticeable when a dragon attacks while you're already fighting something else. On one hand, you'd think that anything that isn't another dragon would perceive the dragon as a bigger threat than you, and temporarily team up with you to take it down. [[GenreSavvy On the other hand]], seeing how the PlayerCharacter will probably coldly hand everyone their respective asses at the same time, they may be making the right decision in teaming up with the dragon.
* In ''VideoGame/FalloutNewVegas'', the two most commonly flagged always hostile enemy types, namely raiders and mutated animals, will gladly fight each other and not the player even if the player is in detection range. This isn't a guarantee though; some raiders will break from the fight to attack you even while a mutated lizard sets fire to their hair, but seeing as how most of the raiders are phenomenally high on chems, there's a hint of justification. Junkies don't exactly make the best choices.
** While an AI's fighting tactics are programed to be most effective against player characters, they don't prioritize the PC in any special way during combat. As far as hostility goes, each enemy is marked as part of faction, and not just like the NCR or Legion. For example [=RadScorpions=] and Fire Ants have their own separate factions and will fight each other because their factions are marked as hostile toward each other. If there is another wasteland human out, they will also be attacked ([[ContractualBossImmunity Unless they are Vulpes Inculta]]). You can even use Testing Cheats to make yourself part of these factions, and thus chum it up with whatever Raider, Robot, or Deathclaw you meet.

[[folder:Wide Open Sandbox]]
* In the ''VideoGame/GrandTheftAuto'' series, even if you're with other gangsters out committing crimes, the cops will only target ''you'' once you have a wanted level. Additionally, if you are in line sight of a cop who's dealing with one of the random AI crooks in the game, no matter how egregious their crime is to your rather petty one, they will IMMEDIATELY stop chasing that criminal to chase you, hilariously sometimes in mid chase or beatdown.
** Taken to stupid extremes in the second game. Want to take the car that someone just stole from you back? [[MostAnnoyingSound "We've got a 10-24 in…"]]. Even worse, they don't care about what gang members are doing… even if it's [[ArtificialStupidity shooting their car until it explodes]].
* In the ''SaintsRow2'' activity, "Fight Club" you get in a cage match to the death with other fighters. The problem? ALL of them go after you; its very rare to see any of them fighting each other, which can make the higher levels ludicrous, especially when you're taking on six opponents at once (though it's VERY satisfying to take them all out).
** Somewhat justified in-story (although it's never explicitly stated) since your character is a well-known gang leader, and defeating you in combat would logically be much better for a fighter's reputation than some other no-name scrapper.
** This also happens in the Demolition Derby. After the initial pileup every single AI car will start coming after you excusively.
* ''VideoGame/InFamous'' on the evil route, as both the police and the bad guys will be out to get you, and it's not rare to beat down the police in the streets, only to have to deal with a rooftop sniper right afterwards, who didn't seem to be shooting when he could've hit the police. Justified in that an evil superhero really is much more dangerous to both sides.
** On the other hand, regardless of your karma, you'll sometimes run into two ''different'' gangs beating the hell out of each other, and only the nearest ones will attack you. There's even a side mission to stop a gang war; if you want, you can just let them fight it out and then mop up the leftovers.
* In the game ''VideoGame/{{Prototype}}'', one of the big features being touted was being the third side in a two-way war. Unfortunately, the Infected almost always target you unless they're under fire from the military, the military targets only the Infected unless you alerted them, but they always target the Infected ''closest'' to you first thus ensuring you'll get hit as well.
** In one boss fight, this is explicitly subverted. [[spoiler:After Greene pops up in OneWingedAngel form in Times Square, the attention indicator will turn red, meaning Alex is an active target of the military. Then the call comes in telling the military to focus ''only'' on Greene, and the indicator turns yellow, meaning that Alex isn't considered an active threat. The military then pays attention only to Greene and ignores Alex.]]
* In ''VideoGame/{{Bully}}'', if you decide to [[VideoGameCrueltyPotential put marbles in front of the door of the boy's dorm and pull the fire alarm]], this is why you should hide in the trash can because for some reason, the first person they go for is always you. Even if you jump out of the trash can when the riot had already started, they may sometimes just turn around and fire at you. This can also happen with other cliques.
** The prefects, however, zig-zag this - if others break the rule, even if you're around breaking rules they'll go after ''them'', too, they won't go after just you.
* In ''VideoGame/{{Minecraft}}'', mobs will not attack other mobs unless they hit each other, which can only happen when a ranged mob tries to hit the player. Even when this does happen, the mobs will wait until there are no players nearby before attacking each other.
** On multiplayer servers, mobs still prioritize players over other mobs, but once they begin following a player they will not switch targets as long as that player is within range. This can lead to large groups of mobs following one player and completely ignoring others.

!!Non-video game examples:
* In ''Anime/YuGiOh5Ds'', on villain unleashes an army of dueling robot, then sets it to Battle Royal mode, where anyone who loses, crashes the D-Wheel. Despite that the rules for battle Royale mode bing "every man for himself," the robots work together, even making themselves crash to help other robots.
