Treyarch officially confirms Black Ops zombies

Freely admitting it’s one of the game’s “worst kept secrets,” Call of Duty: Black Ops developer Treyarch has today formally announced the inclusion of zombies in the shooter’s cooperative mode.

Up to four players can take on the hordes in what’s referred to as “brand new zombie experiences” while the essentials from World at War remain intact; “We’ve taken extra special care to retain the essential ingredients of our Zombie game,” studio head Mark Lamia assures, “and have also crafted a nice surprise for the fans.”

In addition, a new co-op game will be available in the multiplayer mode with Combat Training. “Up to six players can rank up in this dedicated and exclusive multiplayer mode battling against enemy AI,” says the news burst.

This is in addition to the four updated World at War zombie maps that’ll be included in the Hardened and Prestige editions of Black Ops then.

The fun begins worldwide on November 9th.
