Spartan Ops

Spartan Ops is the Halo 4 Cooperative Mode replacing Firefight from Halo 3: ODST and Halo: Reach. It supports up to 4 players and ties into the SPARTAN-IV Program and the Campaign of Halo 4.

Spartan Ops mainly revolves around Fireteam Crimson; a team of Spartan IV's deployed on Requiem. The Storm Covenant and Prometheans are encountered in Spartan Ops.

Overview
Spartan Ops is a free episodic co-oporative series, taking place six months after the end of Halo 4's campaign. Seasons are made up of ten Episodes, containing five Chapters each, for a total of 50 Chapters per Season. Episodes are released in weekly, free DLCs. Each Episode contains short CGI movies, further explaining the story. Your customised loadouts are available for each Spartan Ops mission, and playing will increase your rank and earn you Spartan Points, unlike Campaign. You take control of a team of Spartan IVs known as Fireteam Crimson, and perform various types of objectives, including eliminating all enemies or activating consoles to progress. When it is finished, you are extracted by Pelican. You then gain your Rewards and move on to the next Spartan Ops mission.

Storyline
