We're Certain Treyarch's Got Plenty More To Spill About Call Of Duty: Black Ops.

They haven't — there's plenty more to announce according to developers Treyarch.

One such element, is Call Of Duty: Black Ops' co-op mode. While we already know zombies will make an appearance in some manner, community manager Josh Olin was keen to stress that there's plenty more to talk about.

“We haven’t revealed the co-op mode yet,” Olin told GamerZines at GamesCom.

“I confirmed that part of the Prestige and Hardened Edition copies of the game is the four World at War Zombies levels playable in Black Ops co-operatively, but that’s all we announced.”

He added: “As for what our actual co-op mode is that ships with the game, we’re not ready to reveal that just yet.”

If Treyarch's put the same amount of thought into co-op as they have Black Ops' main multiplayer component, we're certainly in for a treat.
