Halo 4's Spartan Ops promises to continue the fight after the campaign finishes. Each week, 343 Industries plans to release five short canonical missions set six months after the end of the main storyline, which will eventually add up to a 50-mission season told through ten 'episodes.' Better yet, Spartan Ops will also be free, with the first five missions included on-disc.
This new trailer helps to give some context to the action and introduces some of the characters you'll encounter as part of Crimson Team.
Halo 4 is set to release on November 6th. Look out for our full review later this week.
