The first bout of episodic content for the Spartan Ops gamemode of Halo 4 has arrived on Xbox Live this morning. This second episode, titled Artifact, will feature five new missions that further the storyline of the UNSC Infinity.
This is the second episode of a planned ten weeks of additional cooperative content for Halo 4. The Halo 4 update also brings the SWAT game mode from Halo: Reach. Very similar to how it played in the last Halo game, SWAT narrows player options and focuses solely on getting headshots with either the Battle Rifle or DMR and getting one shot kills.
The playlist is currently live, no downloads required, just head to the appropriate game mode and play.
