Treyarch today released a new preview video of the already-leaked Zombie mode in Call of Duty: Black Ops II. The ominous trailer shows exactly nothing, which is par for the course I suppose. What we do know is that the mode is likely to feature zombies, as the name suggests. More details are due to come in a week from now, on September 26th. If you want to see a desolate landscape, a creepy bus, and a promise to show more of nothing in a few days, click the trailer below. Call of Duty: Black Ops II is due to meander its way into billions of dollars on November 13th for PC, PS3, and Xbox 360.
