Cooperative play: Difference between revisions

Co-op gameplay basically involves two or more people playing through the campaign as a team. If one player dies, they can come back to life, or "respawn". The player who dies has to wait until the player(s) who is/are still alive is/are not engaged in combat and is/are at a safe location before they are able to respawn. If all players are killed, they will restart at the last saved checkpoint. Additionally, in ''[[Halo 2]]'', if two players are playing on [[Legendary]] difficulty and ''either'' of them die, then both of them have to start at the last checkpoint. In any of the other ''Halo'' games, nearly all players will attempt [[Legendary]] on co-op, because Legendary is often too difficult to attempt alone. When a player respawns in ''Halo: Combat Evolved'', they are always equipped with an [[MA5B Individual Combat Weapon System|Assault Rifle]] and a [[Type-25 Directed Energy Pistol|Plasma Pistol]]. In the sequels, each level has a designated pair of weapons that respawning characters start with.

In ''Halo: Combat Evolved'' and ''Halo 2'' co-op, when playing a level involving the [[John-117|Master Chief]], both players will control two identical copies of the Chief; when playing a ''Halo 2'' level involving the [[Thel 'Vadam|Arbiter]], both players will control identical Arbiters. The presence of a second version of the character is non-canon, and is never referred to or reflected in any of the cutscenes, with the singular exception of the opening cutscene of ''Halo: Combat Evolved''/''Halo: Combat Evolved Anniversary'', in which two "Master Chiefs" are depicted emerging from cryopods in the ''[[Pillar of Autumn]]'''s cryo-bay. ''Halo 2'' was planned for online co-op mode for up to two players on Xbox Live, but due to time constraints Bungie was not able to perfect online co-op for ''Halo 2'', the user interface still contains clues as to how ''Halo 2'' would have had co-operative game mode, and it's even more apparent modders were able to activate this game mode.

In ''Halo 3'', when there are two players, player one plays as the Master Chief and player two controls the Arbiter. Certain cutscenes and lines of dialogue are altered to reflect the fact that, unlike in the single player mode, the Arbiter never leaves the Chief's side. In addition, all of the Arbiter's lines of dialogue outside of cutscenes are removed. In three or four player co-op, player three controls [[N’tho ‘Sraom|N’tho 'Sraom]] and player four becomes [[Usze ‘Taham|Usze 'Taham]], though these characters do not appear in cutscenes, and are not referred to in dialogue. Player one, as the Master Chief, begins each level and respawns after dying with human weaponry such as the [[MA5C Individual Combat Weapon System|Assault Rifle]] and [[M6G Personal Defense Weapon System|Pistol]], while the other players, as Elites, begin levels and respawn with Covenant weaponry such as [[Type-51 Carbine|Covenant Carbines]] and [[Type-25 Directed Energy Rifle|Plasma Rifles]]. Two player co-op can be played in split-screen mode in all three primary ''Halo'' games, but three or four player co-op in ''Halo 3'' is only available over system link or [[Xbox LIVE|Xbox Live]], with at least two Xboxes with two players on each.

Co-op is also available in ''[[Halo 3: ODST]]''; in the [[Mombasa Streets]] sections of the campaign, when player one controls [[the Rookie]], player two controls an identical [[Orbital Drop Shock Trooper|ODST]]. During flashback missions, player one controls the main character of the flashback, but player two still controls a generic ODST, even if the flashback character is accompanied by other members of [[unidentified Shock Trooper squad|the squad]]. For example, in [[NMPD HQ (level)|NMPD HQ]], the flashback is from the perspective of [[Kojo Agu|Romeo]], who is constantly accompanied by [[Edward Buck|Buck]]. In co-op mode, player one controls Romeo, but player two controls a nameless ODST, leaving Buck as an NPC. The same goes for players three and four. Just as in ''Halo 3'', two players can play on one Xbox with split-screen, but up to four players can play at once via Xbox Live or system link.
