Spartan Ops is a mission-based cooperative mode in Halo 4 in which up to four players work as part of a team of SPARTAN-IVs known as Fireteam Crimson performing various objectives. Players' customized loadouts are available during each Spartan Ops chapter and completing a mission gives players XP towards their next rank. Episodes 1-5 are contained in Halo 4's second disc, and episodes 6-10 are available as free downloadable content from the Xbox Live Marketplace. 

Spartan Ops in Halo 4 requires an Xbox Live Gold membership to play, but the Spartan Ops in Halo: The Master Chief Collection does not.

343 Industries will not be developing a second season.[1]


This section requires expansion.

The story takes place in February 2558, 6 months after the events of the Halo 4 Campaign and mainly revolves around SPARTAN-IV Fireteams Majestic and Crimson, who are deployed on the shield world Requiem. There are ten episodes which contain five mission-based chapters each. Each episode is accompanied by a short CGI movie which explains the story.
