Treyarch and Activision recently released the latest DLC map pack for Call of Duty: Black Ops 2. The pack, titled Vengeance, featured four new competitive multiplayer maps and a zombie mode map set in an underground old-west town. With three map packs now released for Black Ops 2 and the release of the upcoming Call of Duty: Ghosts less than three months away, Treyarch could be forgiven if Vengeance was the final bit of content to be released for Black Ops 2.

That is now the case, however. The developer today posted a new video to its YouTube page that teases some new content for the current iteration of the Call of Duty franchise. The teaser, titled “Origins,” shows four men, some fetishistic close-ups of their gear, and some cryptic images of varied architecture. The final 10 seconds of the tease shows some very rainy trenches and what appears to be an angry, fully-functional giant robot.

The video was published with the tagline, “Every story has a beginning…and an end.” No further information has been revealed, leaving Call of Duty fans to speculate. The odds are certainly in favor of this being a tease for a new zombies mode map, but it’s also certainly possible that Treyarch has something special prepared for its final DLC of this console generation.
