Call of Duty Black Ops: Cold War is growing its zombies mode with yet another map. For now, we don't know much about the new map, titled Mauer Der Toten, but that's going to change tomorrow. In a tweet, developer Treyarch Studios shared a small clip of the new map and announced that a full gameplay trailer would drop July 8.

The snippet, a four-second long clip, leaves a whole lot for imagination. Its first shot is of a large switch being flipped, and the second shows a seemingly underground concrete structure covered in gore. What appears to be a jugger-nog machine is shown, but it looks to be covered in some kind of mold.
