The '''''Halo: Spartan Assault'' co-op missions''' form the [[Cooperative play|co-op mode]] found in the [[Xbox 360]] and [[Xbox One]] versions of ''[[Halo: Spartan Assault]]''. With five missions, the mode focuses 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. Unlike the series' other co-operative modes, [[Firefight]] and [[Spartan Ops]], the Flood missions cannot be completed alone; players must play with a co-op partner over [[Xbox LIVE]]. 

The mode's respawning mechanics work similarly to those in the campaign co-op of the other games in the series. If one player is killed, a countdown begins until they will respawn on their partner. Players can shorten this countdown by purchasing modifiers before the mission begins. Unlike other games, the living player does not have to be out of combat in order for respawning to occur. If both players are killed, the mission will end in failure, and the lead profile will have the option of restarting the mission or quitting.

==Transcript==
''Today [[Roland|I]] need to talk to you about [[2552#November|November 17, 2552]] and the [[Battle of Kenya]]. The official story is that the [[Covenant]] [[glassing|glassed]] the area in a sneak attack, killing thousands before [[United Nations Space Command|we]] could stop them.''

''Truth is... we '''let [[Fleet of Retribution|them]]''' do it.''

''The glassing was a last-ditch attempt to stop an alien infection called the [[Flood]]. Had the plan failed... the [[Earth]] would have fallen in hours.''

''Officially the Flood's all gone. Kaput. But if [[Human|humanity]] encounters the Flood again, [[Spartan Operations|Spartans]] are our first line of defense.''

''You need to know what you could be up against, and you need to train to deal with it. I've loaded up a [[Forerunner]]-themed [[X-40|test location]] and set it to be infested by Flood. Good luck, Spartan.''
