'Call of Duty: Black Ops 2' zombie video teases bus survival mode

A new video on the official Call of Duty YouTube channel teases what sort of zombies may be coming to Call of Duty: Black Ops 2 when it hits this fall.

A new video on the official Call of Duty YouTube channel teases what sort of zombies may be coming to Call of Duty: Black Ops 2 when it hits this fall.

In the video we catch a glimpse of a rusted out tour bus and lots of very angry zombies attacking it. It appears that the bus could be traveling through a post-nuclear Nuke Town. It also appears that the bus' windows are boarded up and that at least some aspect of the game's zombie mode will have survivors defending themselves on a moving bus.

Black Ops 2 Zombies makes its world premiere on September 26th, according to the YouTube video description.

Not much is known about what role zombies will play in upcoming Treyarch shooter Call of Duty: Black Ops 2, beyond the fact that the game will include a zombies mode.

The developer has said that the zombie mode will use the Black Ops 2's multiplayer engine and support up to 8-player co-op.

Zombies have become one of the trademarks of Treyarch's Call of Duty games. Call of Duty: World at War was the first game to include a zombie survival mode. Call of Duty: Black Ops amped that mode up quite a bit, adding back stories and a number of major downloadable updates.

Today's video teaser is the second released this week. Yesterday's was simply an old television showing a static-filled image of something on fire, perhaps a reference to an easter egg ending found in Black Ops' zombie mode.
