The official Call of Duty YouTube channel released a preview of the upcoming zombie mode for Call of Duty: Black Ops II. The video shows zombies attacking a tour bus. Black Ops II is the latest game in the popular Call of Duty first-person shooter franchise. Two previous entries in the video game series–Call of Duty: World at War and Call of Duty: Black Ops–featured a “zombie mode” during which players worked together to battle waves of undead soldiers. Other than confirming that zombies will return for Black Ops II, not much else has been revealed about the latest iteration of the zombie mode. According to the preview video, more details will be revealed when the Black Ops II zombies make their world premiere on Wednesday, September 26th. Be sure to stay tuned to Black Ops’ Facebook page for the latest information. Call of Duty: Black Ops II arrives on PlayStation 3, Xbox 360, Nintendo Wii U, and Microsoft Windows this November.
