A Call of Duty teaser video has appeared on the game’s official YouTube channel. Many speculate it has something to do with zombies for Black Ops 2, which Treyarch has teased, hinted at, dangled, and sort of confirmed on and off since the game was announced. Zombies are going to part of the game somehow, now, whether that is just in multiplayer, or single-player, or hell, both, remains to be seen for now. Keep hope alive, etc. Enjoy the tease for whatever it is below.
