Co-op is a multiplayer gametype found in all ''[[Halo]]'' games except ''Halo PC'' and ''Halo 2 for Windows Vista''. It allows two or more people to play the campaign together. If one character dies, he or she will respawn with the weapons they begin the level with. The player who dies has to wait until the player who is still alive is not engaged in combat and is at a safe location to be able to respawn. If both players are killed, both you restart at the last checkpoint. Additionally, in ''[[Halo 2]]'', if you are playing on [[Legendary]] and either of you die, both of you have to start at the last checkpoint. Though in any of the other ''Halo'' games, nearly all players will do Legendary on co-op, because Legendary is often too difficult to attempt solo. Although in Halo 3 where it is different, you dont respond at the last checkpoint when both players die.
In Halo and Halo 2 co-op when playing as the Master Chief, both players will be in control of identical SPARTAN IIs. This out right contradicts many messages for these two games that state that the Master Chief is the ''last SPARTAN'', not one of the last. The "Other SPARTAN" does not appear in Halo 3, being replaced by the Arbiter. Similarly, when playing Arbiter missions in Halo 2, both player will control identical "Arbiters."

In ''[[Halo 3]]'', when there are two players, one player is the Master Chief and the other is the Arbiter. It is somewhat the same with three players, with the addition of [[N’tho ‘Sraom]] as another playable character. If a fourth player is available, the Elite [[Usze ‘Taham]] will be playable. It should be noted that the players can not choose who they play as and the game will randomly select who plays as who. Co-op can be played on split screen on ''Halo'' and ''[[Halo 2]]'', but can be played either split screen or over Xbox Live in ''[[Halo 3]]''.

==Co-op Game-play==
Co-op game play is very different from single player, there are several things that you can do (with the exception of ''Halo 2'') in regards to game play, many people don't realize how different co-op play is from single play, for instance, when you die in co-op play in ''Halo 3'' you respawn with two Frag Grenades/Plasma Grenades (depending on if you are an Elite, or if you are the Master Chief), a full Battle Rifle/Carbine and Assault Rifle/Plasma Rifle. In Single play, however, you start off most often with different weapons, such as a Pistol and Assault Rifle. In single play the Arbiter has a range of devices and weapons (anything from the Energy Sword to an auto stealth unit in his armor). Conserving ammunition is a big part of single player as well, as running out of ammo is a common problem. Brute Chieftain's are generally extremely difficult to kill, as they are surrounded by [[Brutes]], and any one Brute can kill you, and they carry weapons of enormous fire power, often only needing one shot to kill you.

==Strategies==
===Coward Method===
First and foremost, the "coward" method is basically having player A hides in a safe spot while player B charges forward and kills everything with impunity. This method is frowned upon greatly, and is used commonly, though it cannot be used in ''Halo 2'' on Legendary. The best way to use this method is to play as the Arbiter in ''Halo 3'', because he has Plasma Grenades to stick enemies with, and to alternate players so that everyone gets a turn, or you can have one sniping, so the player is not necessarily safe, and is contributing.

The variation to this method is single player, where it is actually one person playing on co-op, using the method stated above.

===Full Shotgun===
Both players charge the enemy, though this method is harder, it will make a more enjoyable playing experience, and will be a true test of skill to get through levels, though this is useless for single player experience. To use this successfully, you will both need to coordinate movements with each other so that splash damage attacks and/or friendly fire does not hurt the other player

===Run and Gun===
Attempting to get through the level as quickly as possible while also trying to get the most points possible. This method often involves vehicles and ignoring many enemies that you may otherwise be inclined to shoot. The reason players do this is generally because they want the Legendary symbol for their Xbox Live Account, or they may wish to get the meta-game achievement by relying mainly on the time bonus for the level.

-'''Co-op''' is a [[multiplayer]] gametype found in all [[Halo#Video Games|''Halo'' games]] except [[Halo: Combat Evolved (PC port)|''Halo: Combat Evolved'' for PC]], [[Halo 2 (Windows Vista)|''Halo 2'' for Windows Vista]], and ''[[Halo: Spartan Strike]]''. It allows two or more people to play together through the [[campaign]] or dedicated co-op modes.

+Co-op is a multiplayer gametype found in all ''[[Halo]]'' games except ''Halo PC'' and ''Halo 2 for Windows Vista''. It allows two or more people to play the campaign together.

Although in Halo 3 where it is different, you dont respond at the last checkpoint when both players die.
-Co-op gameplay consists 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 or one of the players who are still alive are not engaged in combat and are at a safe location before they are able to respawn. When a player respawns in ''Halo: Combat Evolved'', they are always equipped with an [[MA5B assault rifle]] and a [[Type-25 plasma pistol]]. In the sequels, each level has a designated pair of weapons that respawning characters start with. 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 (similar to the effect that the Iron Skull has on cooperative play).
+In Halo and Halo 2 co-op when playing as the Master Chief, both players will be in control of identical SPARTAN IIs. This out right contradicts many messages for these two games that state that the Master Chief is the ''last SPARTAN'', not one of the last. The "Other SPARTAN" does not appear in Halo 3, being replaced by the Arbiter. Similarly, when playing Arbiter missions in Halo 2, both player will control identical "Arbiters."
-In many of the other ''Halo'' games, players will often attempt to beat [[Legendary]] in co-op instead of single player, because they consider Legendary too difficult to attempt alone. In ''[[Halo: Reach]]''  this tactic is less feasible, because difficulty "scales" in co-op; the more players, the greater the difficulty. Scaling is also found in ''[[Halo 4]]'', albeit to a less noticeable degree than was present in ''Reach''. ''[[Halo 5: Guardians]]'' also has scaling. Generally however, the benefit of added players more than makes up for the increased difficulty.
+In ''[[Halo 3]]'', when there are two players, one player is the Master Chief and the other is the Arbiter. It is somewhat the same with three players, with the addition of [[N’tho ‘Sraom]] as another playable character. If a fourth player is available, the Elite [[Usze ‘Taham]] will be playable.

+==Co-op Game-play==
-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]]''<nowiki>'</nowiki>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.

+==Strategies==
-[[File:Halo 3 - Cooperative.jpg|thumb|400px|''[[Halo 3]]'' allows players to assume the role of John-117, Thel 'Vadam, Usze 'Taham and N’tho 'Sraom in cooperative play.]]
+===Coward Method===
-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 the Arbiter's lines of dialogue outside cutscenes are removed. In three or four player co-op, player three controls [[N’tho ‘Sraom]] and player four becomes [[Usze ‘Taham]], though these characters do not appear in cutscenes, and are not referred to in dialogue. Player one, as the Master Chief, begins most level and respawns after dying with Human weaponry such as the [[BR55HB battle rifle|battle rifle]] or [[MA5C assault rifle|assault rifle]], while the other players, as Elites, begin most levels and respawn with Covenant weaponry such as [[Vostu-pattern carbine|Covenant carbine]]s and [[Okarda'phaa-pattern plasma rifle|plasma rifle]]s. 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]], with at least two Xboxes with two players on each.
+First and foremost, the "coward" method is basically having player A hides in a safe spot while player B charges forward and kills everything with impunity. This method is frowned upon greatly, and is used commonly, though it cannot be used in ''Halo 2'' on Legendary.

-=== ''Halo Wars'' ===
+The variation to this method is single player, where it is actually one person playing on co-op, using the method stated above.
-Co-op is available in the ''[[Halo Wars]]'' campaign, both via system link and over Xbox LIVE. However, unlike in other Halo games where co-op can be played on a single console, it is not possible to play local co-op in ''Halo Wars''.
-In ''Halo Wars'' co-op, two players effectively control two separate armies that work in tandem. Players utilize the same bases and spawn buildings and units from a single pool of resources.
+===Full Shotgun===
+Both players charge the enemy, though this method is harder, it will make a more enjoyable playing experience, and will be a true test of skill to get through levels, though this is useless for single player experience. To use this successfully, you will both need to coordinate movements with each other so that splash damage attacks and/or friendly fire does not hurt the other player
-=== ''Halo 3: ODST'' ===
+===Run and Gun===
-Co-op is also available in ''[[Halo 3: ODST]]''; 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. In the [[Mombasa Streets]] sections of the campaign, where player one controls [[the Rookie]], players two through four each control an identical [[Orbital Drop Shock Trooper|ODST]]. During flashback missions, player one controls the main character of the flashback, but the other players still control generic ODSTs, even if the flashback character is accompanied by other members of [[Alpha-Nine|the squad]]. For example, in [[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 in levels where more members of the squad are available.
+Attempting to get through the level as quickly as possible while also trying to get the most points possible. This method often involves vehicles and ignoring many enemies that you may otherwise be inclined to shoot. The reason players do this is generally because they want the Legendary symbol for their Xbox Live Account, or they may wish to get the meta-game achievement by relying mainly on the time bonus for the level.
-In gameplay terms, each player can access the map and drop their own waypoint, which will show up on everyone's map, but only on the compass of the player who placed it. In addition, all players download all [[Audio log (Halo 3: ODST)|Audio Logs]], no matter who actually accesses the terminals. Only one log can play at a time, and any player can stop the playback or start the playback of a different log.

-Finally, ''ODST'' adds a new co-op multiplayer gametype called [[Firefight]], in which players are allowed to pick their character, choose their personal emblem, and decide whether or not their character is wearing their helmet (with the exceptions of the Rookie, who must wear his helmet, and of [[Avery Junior Johnson|Sergeant Johnson]], who cannot wear one). For more details on Firefight, see its main article.

-=== ''Halo: Reach'' ===
-''Halo: Reach'', like its predecessors, has full co-op features, but unlike the previous games, no player's appearance is set. Each player can extensively customize the appearance of [[SPARTAN-B312|Noble Six]] in Campaign mode, and this appearance is applied to their character in co-op as well. No changes are made to Campaign dialogue to reflect the fact that there are up to ''four'' "Noble Sixes".
-The number of enemies is determined by how many players are present. For example, on the final section of the level ''[[Winter Contingency]]'', there would be two [[Sangheili Zealot]]s in total on campaign solo. However, if there are two players on cooperative play, there would be three Zealots in total.
-When playing co-op through System Link or Xbox LIVE, each player can see their own version of Noble Six in cutscenes. During split-screen co-op, cutscenes depict the version of Noble Six belonging to the player who triggered the cutscene.
-=== ''Halo: Combat Evolved Anniversary'' ===
-[[File:AnniversaryCoop.png|thumb|400px|Cooperative play, as shown in ''[[Halo: Combat Evolved Anniversary]]''.]]
-''[[Halo: Combat Evolved Anniversary]]'', unlike the original ''Halo: Combat Evolved'', supports 2-player co-op through Xbox LIVE, as well as split-screen and System Link.
-=== ''Halo 4'' ===
-Like its Xbox 360 brethren, ''[[Halo 4]]'' features the standard co-op version of the campaign, with two players able to play locally on one Xbox 360, and up to four players playing via System Link or over Xbox Live. Because the game opens with the Master Chief isolated in the ''[[Forward Unto Dawn]]''<nowiki>'</nowiki>s cryo-bay, there is no contextual reason for other characters to be present, so, like the original ''Halo'' and ''Halo 2'', all players in co-op mode control duplicate "Master Chiefs". It is unclear exactly what governs which weapons a player will respawn with; players have been reported spawning with a wide variety of weaponry, including cases where a respawning player will be holding a weapon with a partially-emptied clip. During the {{Pattern|Karo'etba|Ghost}} escape sequence at the end of the level [[Forerunner (level)|Forerunner]], players who die will actually respawn in new Ghosts, so it will never become impossible to finish the level.
-''Halo 4'' also introduces the new [[Spartan Ops]] mode, a story-based set of missions taking place after the end of ''Halo 4''<nowiki>'</nowiki>s campaign intended to be played co-operatively with up to four players. Non-interactive cutscenes focus on the story of [[Fireteam Majestic]], and gameplay levels focus on [[Fireteam Crimson]], which is made up of the player's customized Spartan-IVs from Infinity mode.
-=== ''Halo: Spartan Assault'' ===
-The '''''[[Halo: Spartan Assault co-op missions|Flood missions]]''''' form the co-op mode found in the Xbox 360 and Xbox One versions of ''[[Halo: Spartan Assault]]''. There is no co-operative version of the campaign. With five missions, the Flood missions focus on preparing [[SPARTAN-IV Program|SPARTAN-IV]]s for the hypothetical return of the [[Flood]]. Unlike the campaign mode, which represents a recreation of canonical events, the Flood Missions are pure simulation. Like the series' other cooperative modes, [[Firefight]] and [[Spartan Ops]], players fight together against waves of enemies to record a high score. Unlike Firefight and Spartan Ops, the Flood missions cannot be completed alone; players must play with a co-op partner over [[Xbox LIVE]].
-=== ''Halo 2: Anniversary'' ===
-''[[Halo 2: Anniversary]]'', unlike the original ''Halo 2'', supports 2-player co-op through Xbox LIVE, as well as split-screen and System Link.
-=== ''Halo 5: Guardians'' ===
-In ''Halo 5: Guardians'' co-op, the players can choose to play as John-117, Fred-104, Kelly-087, Linda-058 or Jameson Locke, Holly Tanaka, Olympia Vale, and Edward Buck respectively. Each Spartan spawns with a different loadout with different abilities. The number of enemies is determined by how many players there are. Unlike past ''Halo'' games there is no splitscreen co-op. Dialogue can be altered depending on which character is present for events. Similarly each character will give and receive different dialogue to and from NPCs in the weapons-down missions.
-In addition, players not playing as John-117 or Locke can hear additional dialogue from these characters that would otherwise never be heard in solo play.

-===''Halo Wars 2''===
-''Halo Wars 2'' co-op works largely similar to the first ''Halo Wars'' with players sharing resources and not featuring splitscreen.
-===''Halo Infinite''===
-In ''[[Halo Infinite]]'', campaign co-op was not available at launch. Like ''Halo: Combat Evolved'' and ''Halo 4'' all the players play as John-117. Due to the open world nature of ''Halo Infinite'', players can not get more than a thousand feet from each other before hitting a kill barrier. On September 1, 2022, 343 Industries announced that splitscreen for the campaign was canceled. Flighting for network co-op took place from July 15, 2022 to August 1, 2022. The full release of network co-op released in the [[Winter Update]].
-=== Differences ===
-Co-op gameplay is very different from single-player gameplay; there are several new strategies and alterations present. Players who stray too far apart will be teleported back together once a player hits a loading zone. Starting and respawn weapons tend to vary between single-player and co-op, as do the starting weapons of each character and the strategies that can be used in co-op—some of which are documented below.
-== Strategies ==
-=== Coward Method ===
-The "coward method" is basically having one player hide in a safe spot while the other player charges forward and kills everything with impunity, charging again and again as they die until no opposition remains. This method of progressing is generally frowned upon in the community, but it is still commonly used to beat the campaigns on Legendary. It cannot be used in ''Halo 2'' on Legendary, however, as if one player dies, both must restart from a checkpoint. This tactic is also rendered useless with the Iron skull active.
-This method can also be used by one person playing as two characters on co-op, provided that they can place the "coward" in a safe, unreachable place.
-In many ways, it is very much the same as the "cannon fodder galore" strategy, in which the "brave person" throws enough of themself at the enemy until they go down. Whilst not the most creative or innovative idea, it is still a valid strategy just not a very ''good'' or realistic one.
-=== Full Shotgun ===
-This method involves all players charging at the enemy. This method is rather foolhardy, and much more difficult than standard play. To use this technique successfully, players will need to coordinate movements with each other to avoid wounding or killing each other with splash damage or friendly fire.
-=== Run and Gun ===
-This method consists of attempting to get through the level as quickly as possible, while also trying to get the most [[Campaign Scoring|points]] possible. It often involves using vehicles and ignoring many enemies that the player may otherwise be inclined to shoot. The reason players do this is generally because they want the Legendary symbol for their service record; they may also wish to get the [[Campaign Scoring#Achievements|meta-game achievements]] by relying mainly on the time bonus for the level.
-=== Combat Roles ===
-This method makes up for the 2 or 3 weapon limit and has players focus on specific aspects of combat, such as enemy types or positioning. One of the most ideal strategies utilizes one of the players using weapons less resistant to [[energy shielding|shielding]] while another player uses weapons less resilient to non-shielded enemies. This way, shielded enemies would lose their shielding rather quickly and become vulnerable to the other player who would have the proper weapon equipped to finish off the enemy, effectively removing the need to constantly switch weapons. Ideally, the player assigned to shielded enemies would utilize [[Type-25 plasma pistol|Plasma]] [[Type-54 plasma pistol|Pistols]] for their overcharged shot while the player assigned to take out the non-shielded enemy would utilize headshot weapons, namely a [[Battle rifle|Battle Rifle]] or [[Vostu-pattern carbine|Covenant Carbine]], forming a two person [[Noob Combo]].
-=== Two-Way Attack ===
-Plan is simple: one player attack the enemy from the front, whilst the other player goes round and either flanks the enemy from behind or attack them from the side. Can be used against the more powerful enemies in which two or more players would gang up to take a powerful enemy down or, can be used to eliminate large groups of Covenant using combined Assault or Battle Rifle fire.
-Alternatively, two players may not be needed for this method. It can be done using the UNSC Marines as a distraction for the Covenant whilst the lone player attacks from the side (or flanks). One example of this strategy actually being ''used'' is in the level "Tayari Plaza" in Halo 3 ODST, Australian marine Chips Dubbo suggests to Buck "flank the Covenant on the streets" whilst Dubbo and his team-mate distract the Brutes.
