Call of Duty: Black Ops 2 developer Treyarch is teasing new content for the game with a new video called "Origins."
The studio began teasing a reveal on its Twitter account yesterday, posting a Vine and a screenshot from the video above. The trailer includes silhouettes of four men and a brief clip of trench warfare that ends with a giant robot.
Treyarch has released three downloadable expansions for Black Ops 2 — Revolution, Uprising and Vengeance — so this teaser is presumably related to the fourth and final add-on for the nine-month-old shooter. The tone of the video suggests that Origins may be related to content for Black Ops 2's Zombies mode.
