One of the early details on Call of Duty: Black Ops was that it would feature four-player co-op, but if you thought that'd mean playing through the main campaign with three of your friends, you can give up that dream right now. Treyarch has confirmed that the co-op in Black Ops will be entirely separate from the single-player story campaign, and will instead be in "unique" modes built specifically for multiple players.

"Single-player is the epic, cinematic, seat-of-your-pants thrill ride that you star in," said Treyarch head Mark Lamia to MTV Multiplayer, breaking down the main modes of Black Ops. "Then there's multiplayer, when you want to play competitive with your friends and really chisel and hone your skills and do that addictive experience. And then co-op is for when you want to have a blast with your friends, just sitting on the couch and having an awesome co-op experience.

"We're crafting unique co-op modes around that experience, but it is different than what people think," Lamia continued. He wouldn't give much detail about Black Op's co-op modes, but he confirmed they would be different than the Spec Ops mode in Modern Warfare 2. He also wouldn't confirm whether there will be a return of the Zombies co-op mode from Treyarch's last Call of Duty game, World at War.
