While there’s no official announcement, Treyarch has released a new trailer titled “Origins”, which may suggest more upcoming DLC for Black Ops II.

The “Origins” teaser features younger versions of the original four Black Ops: Zombies characters Nikolai, Dempsey, Takeo and Richtofen. With the tagline “Every story has a beginning…and an end,” and a black-and-white filter, this could very well be a hint at a new Zombies-themed DLC, set in the past and future, in correlation with Black Ops II‘s campaign.

If “Origins” truly is DLC for Black Ops II, it would be the fourth DLC add-on, and presumably the last, before the release of Call of Duty: Ghosts later this year.
