The Undead Are Now Officially Confirmed For Call Of Duty: Black Ops.

The studio describes the "anticipated feature" as one of COD's "worst kept secrets" — which is becoming a catch all for any announcement which gets leaked early.

"Zombies have been such a hit with our community that we were committed to bringing brand new zombie experiences to Call of Duty: Black Ops," studio head Mark Lamia said. Once again, the mode will boast four player co-op, in which players attempt to stave off waves of the undead.

Four of the original maps from Call Of Duty: World At War will return in the Prestige and Hardened editions of the game. There's no word as to how many maps Black Ops' zombie component will have in total, but we imagine there'll be a couple.

Still, it's officially announced now.
