History Main / CoOpMultiplayer

* ''VideoGame/GoldenAxe'': The 2-player co-op of the UsefulNotes/SegaGenesis version was removed from the otherwise enhanced UsefulNotes/SegaCD version.

* ''Street Smart'', {{Creator/SNK}}'s first FightingGame, was also the first FightingGame to feature simultaneous two-player co-op.
* ''VideoGame/SuperSmashBros for Wii U'' has introduced 2-player cooperative Classic and All-Star modes, as well as co-op event matches for ''Brawl'' and ''Wii U''.

* A {{pinball}} example: ''Pinball/TeenageMutantNinjaTurtlesStern'' has a cooperative mode where every player in a multiplayer game shares points and progress in modes.

* ''Quartet'': Originally a four-player UsefulNotes/ArcadeGame, hence the title.

* ''[[VideoGame/TaleSpinSega TaleSpin]]'' (UsefulNotes/SegaGenesis)

* ''Bloodwych'', a ''VideoGame/DungeonMaster''-like game with a split screen to accommodate two players simultaneously.

* ''VideoGame/SplinterCell'' Since the third game onwards.
* The [[FarmLifeSim farming simulator]] ''VideoGame/StardewValley'' is designed to allow for co-op play with up to four players. It also has exploration and combat modes in the vein of ''VideoGame/{{Minecraft}}'' or ''VideoGame/{{Terraria}}''.

* Creator/MidwayGames' ''VideoGame/{{Xenophobe}}'' handled three players on a split screen. Most ports supported two players only.

* ''Videogame/DeathSpank''

* [[MultipleHeadCase Cho'Gall]] in ''VideoGame/HeroesOfTheStorm'' is the first and only co-op ''character'' in a [[MultiplayerOnlineBattleArena MOBA]] game. One player controls Cho, who controls the actual unit's movements and has his own set of close-range abilities, and another controls Gall, who has a set of highly damaging long-range spells. The two of them have some abilities that require some coordination to use effectively.

* ''VideoGame/TheLegendOfZeldaTheWindWaker'' lets a second player connect a UsefulNotes/GameBoyAdvance to the game in order to help the main player by dropping bombs on his local field of view and letting him buy some items, as long as Link collects a certain object early on in the game. This feature was removed in the UsefulNotes/WiiU VideoGameRemake.

* The canceled ''Videogame/MechWarrior 3050'' was planned to feature possibly the strangest example, allowing a second player to take on half of the controls used in single-player mode to act as a �weapons officer.�

* ''Franchise/StarWars Arcade'' has player 1 play as the pilot of an X-Wing; their cursor is fixed in the center of the screen and they must move around in order to aim. Player 2 can play alongside player 1 as the gunner, and can freely move their cursor around the screen.

* Creator/SegaPinball's ''Pinball/BatmanForever'' has a "league" option, where up to six players form teams of two, then play for a combined score against the others.

* ''VideoGame/ZombiesAteMyNeighbors'' and its sequel ''Ghoul Patrol'' let Zeke and Julie walk around independantly, although they're stopped by the edge of the screen and have to contend for the limited available supplies.

* ''[[VideoGame/LennasInception Lenna's Inception]]''

[[folder:Beat Em Ups]]

* ''VideoGAme/FightingForce'' 2 Players can fight along side each other split screen to defeat Zeng and his men!

* ''VideoGame/SvenCoop''

* ''VideoGame/ModernWarfare 2/3''[='=]s Campain missions are cut and made into "Spec Ops" Missions
* Also in ''VideoGame/CallOfDuty'', VideoGame/NaziZombies. Four players vs endless horde of undead in a weird hybrid of an FPS and maybe Tower Defence.
* ''VideoGame/NoOneLivesForever 2'' had a separate co-op campaign from the main campaign.
* ''VideoGame/OverkillsTheWalkingDead'', developed by the ''Payday'' creators, had elements of both ''Payday'' and ''Left 4 Dead''
* ''VideoGame/PaydayTheHeist'', ''VideoGame/{{Payday 2}}'', and ''VideoGame/{{Payday 3}}''.
* ''VideoGame/PerfectDark'' and ''Perfect Dark Zero''. The original created a blonde as the second player's default skin (though in-story characters could be unlocked), while in the prequel any second player usually took control of a character who was already in the story (e.g., the third mission is an EscortMission of Joanna helping her dad escape Hong Kong - the second player would be her dad). The original also [[InvertedTrope inverted]] this trope with a "counter-operative" mode, where the second player would be one of the level's mooks.
* ''VideoGame/SecondExtinction'' was a dinosaur-themed [[WideOpenSandbox open world]] co-op shooter by the makers of ''Generation Zero'', which was sold in Steam Early Access for a few years but cancelled just before official release due to "insufficient profitability".
* ''VideoGame/{{Borderlands}}''
* ''VideoGame/TimeSplitters'': A second player can tag along to help with the missions.
* ''VideoGame/TeamFortress2''[='=]s Mann vs. Machine mode pits one team of 3-6 against a swarm of computer-controlled AIs.
* ''VideoGame/UnfortunateSpacemen'': Most of the players are spacemen working towards a common goal: escape the failing space outpost. They must do this while trying to avoid being killed by [[AsymmetricMultiplayer the one player playing the killer alien]].
* ''VideoGame/{{Unloved}}'', an indie horde shooter based on the ''VideoGame/{{Doom}}'' mod of the same name.

* ''VideoGame/BangOnBallsChronicles''

* ''VideoGame/{{Tetris}} Party'', ''[[VideoGame/TetrisTheGrandMaster Tetris: The Absolute - The Grand Master 2 PLUS]]'', and Tengen's unlicensed NES version of ''Tetris'' have a mode in which two players co-operate in dropping pieces onto the same field. ''Tetris Kiwamemichi'' has a mode like this, but for '''four''' players.

[[folder:Shoot Em Ups]]

* ''VideoGame/MassEffect3'', although allies are FriendlyFireproof, handwaved the same way as in the singleplayer.
* ''VideoGame/DragonAgeInquisition''

* Various single-player games like ''VideoGame/{{Rune}}'', ''VideoGame/SystemShock2'', ''VideoGame/CommandAndConquerRenegade'' and ''VideoGame/{{Unreal|I}}'' have had their original campaigns superbly [[GameMod modded]] for coop MP by fans.
* ''VideoGame/AWalkInTheWoods''
* ''VideoGame/AWayOut'' and ''VideoGame/ItTakesTwo'' require two players to even play the game, and both must accomplish tasks to aid each other.
* A {{pinball}} example: ''Pinball/TeenageMutantNinjaTurtlesStern'' has a cooperative mode where every player in a multiplayer game shares points and progress in modes.
* In the pinball game ''Pinball/TheMandalorian'', changing the mode to "Co-op" before starting a multiplayer game causes everyone to share a score and Beskar (though any purchases made with the latter are still individual).

* ''VideoGame/GrandTheftAutoSanAndreas'' featured co-op missions and freeroaming in this form, though the PC version requires a GameMod to enable it.
* ''VideoGame/DriverSanFrancisco'', Wii edition only. P1 drives, P2 shoots.
* ''VideoGame/StreetFighterXTekken''. You can manually switch characters, Launchers automatically switch the current character out, and there are two super move types that incorporate co-op gameplay- Cross Arts, where both players use a powerful move to deal huge amounts of damage, and Cross Assaults, where both players can fight together simultaneously. In single-player mode, the player controls both characters and their switching, while the AI fights with them during a Cross Assault.
* ''VideoGame/UrbanReign'': in the game's Challenge Mode Co-Op works more like the games under the Individual header, while a cheat code will allow the second player to control the helper character in the Story & Free Mission modes. Under this circumstance the camera still only follows the 1st player, and it's Game Over if they lose while the second character can be knocked out without consequence.
* The co-op mode in ''VideoGame/AceCombatAssaultHorizon'' basically takes the single-player levels starring Col. Bishop (the main PlayerCharacter) and lets three players play as him and two unnamed members of his squadron, who are little more than {{Attack Drone}}s in single-player. The host of the game always plays as Bishop and basically directs the gameplay. Weirdly, one of Bishop's three wingmen, Guts, remains computer-controlled even in co-op.
* ''VideoGame/ArtemisSpaceshipBridgeSimulator''. It can be debated whether Helm (moves the ship) or Captain (no actual ship controls, but coordinates the other players) is the "main" player, but e.g. Engineering's only effect is to make other stations' tools stronger or weaker (preferably boosting the ones that are currently or about to be needed), and Comms can seem like TheLoad.
* ''VideoGame/TheBindingOfIsaac'' lets another player join the game as a co-op baby at the cost of one heart container from the player. They're fairly basic and work like a controllable familiar, which can fire tears and fly, but there are some special co-op babies with unique effects. ''Repentance'' increases the player cap to 4 and adds a true co-op multiplayer mode to the game.

* ''VideoGame/SinAndPunishmentStarSuccessor'' allows a second person to control another gun. The second player doesn't have any charge shots or melee attacks, and doesn't take damage. This does, however, mean that [[WeCannotGoOnWithoutYou the death of Player 1 is a Game Over for both players]].

* ''VideoGame/F15StrikeEagle'' is a Jet Fighter game for the NES that practically NEEDED an assistant on the higher difficulties. On 'easy', the jet would practically fly itself (auto-speed, auto-level, auto-landing), you had 1 type of multi-purpose missile, and 1 type of counter-measure. On the hardest difficulty there were 3 types of missiles, 2 types of counter-measures, and you had to handle all normal flight controls (speed/leveling/etc...). Needless to say, with only 4 buttons there were LOTS of multi-button controls to switch which missile was loaded, or which C-M to launch, or how to adjust speed. The second player's controller did nothing BUT these secondary tasks.
* ''VideoGame/DriverSanFrancisco'' allows an additional player with a Nintendo DS to [[HackingMinigame take some police attention away from the other player(s), place roadblocks, search the map for power-ups, and place a movable marker on the map.]]
* ''Franchise/StarWars Arcade'' has player 1 play as the pilot of an X-Wing; their cursor is fixed in the center of the screen and they must move around in order to aim. Player 2 can play alongside player 1 as the gunner, and can freely move their cursor around the screen.
* An arcade game, ''Lucky & Wild'', features player one having to simultaneously drive a car and shoot enemies. Player two can join in but only as an extra gun.
* ''VideoGame/AffordableSpaceAdventures'' allows multiple players to split up the tasks involved in piloting the Small Craft; The game pad player always has control of the InventoryManagementPuzzle that is access to toggling the ship's individual systems, while a second player can take charge of actually flying the Small Craft in-game and a third player still can take control of the ship's searchlight/scanner.
* [[MultipleHeadCase Cho'Gall]] in ''VideoGame/HeroesOfTheStorm'' is the first and only co-op ''character'' in a [[MultiplayerOnlineBattleArena MOBA]] game. One player controls Cho, who controls the actual unit's movements and has his own set of close-range abilities, and another controls Gall, who has a set of highly damaging long-range spells. The two of them have some abilities that require some coordination to use effectively.
* ''VideoGame/Pikmin4'' has its co-op mode consist of the second player in the role of "Pebble Pitcher". As the name implies, this comes in simply throwing items onto the field, mainly pebbles that can stun enemies or help destroy obstacles, but also any items that Player 1 has in their inventory such as Scrummy Bones and Pikpik Carrots.

* ''VideoGame/SuperMarioBros1''
* ''VideoGame/DonkeyKongCountry''

* ''VideoGame/{{FarCry 3}}'' had a separate 4-player co-op campaign from the main campaign. Later games in the series let you drop into your friend's game as a second character.

* ''VideoGame/{{Redfall}}'', a co-op [[WideOpenSandbox open-world]] shooter.

* ''[[VideoGame/FirstEncounterAssaultRecon F.E.A.R. 3]]'' was designed around 2-player co-op, though it can be played solo.

* ''VideoGame/{{GTFO}}''

* ''VideoGame/HalfLifeDecay''
* Most ''Franchise/{{Halo}}'' games, namely: ''VideoGame/HaloCombatEvolved'', ''VideoGame/{{Halo 2}}'', ''VideoGame/Halo3ODST'', ''VideoGame/HaloReach'', ''VideoGame/{{Halo 4}}''

* ''VideoGame/AWalkInTheWoods''

* ''Warpman''
* Creator/MidwayGames' ''Xenophobe'' handled three players on a split screen. Most ports supported two players only.

* ''VideoGame/NewSuperMarioBrosU''
* ''VideoGame/NewSuperMarioBrosWii''

* ''VideoGame/TheLegendOfZeldaTheWindWaker'' lets a second player connect a UsefulNotes/GameBoyAdvance to the game in order to help the main player by dropping bombs on his field and letting him buy some items, as long as Link collects a certain object early on in the game. This feature was removed in the UsefulNotes/WiiU VideoGameRemake.

* The [[SimulationGame farming simulator]] ''VideoGame/StardewValley'' is designed to allow for co-op play with up to four players. (It also has exploration and combat modes in the vein of ''VideoGame/{{Minecraft}}'' or ''VideoGame/{{Terraria}}''.)

* ''Just One'' is a cooperative party game based on giving clues to help one teammate discover a mystery word, without giving the same clue as another teammate because duplicate clues are eliminated.

All players are on the same team, playing against the VideoGameAI; this only counts if it's the "main game" and not multiplayer with the teams set to be players vs. CPU. The characters played by additional players are almost always {{Canon Foreigner}}s, rarely making it past {{Road Cone}}s. Comes in several flavors:

* ''VideoGame/{{Pikmin}} 2''

* ''VideoGame/Pikmin4'' has its co-op mode consist of the second player being able to throw items, namely pebbles that can stun enemies or help destroy obstacles, but also any items that Player 1 has in their inventory such as Scrummy Bones and Pikpik Carrots.
