Treyarch will follow the trend set by Infinity Ward in regards to the Call of Duty franchise and its implementation of co-op in Call of Duty: Black Ops. In a recent interview, studio head Mark Lamia dropped the bombshell that Black Ops will have no co-op campaign but will feature a range of "unique co-op modes" instead.

"Single-player is the epic, cinematic, seat-of-your-pants thrill ride that you star in. 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."

At a recent Activision press conference Lamia also said:

“The game will also feature distinct multiplayer and co-op modes, and though specifics regarding our co-op mode have not yet been revealed I can tell you that we’ll be delivering a unique online co-op mode for up to four players, with local split-screen for two.”

We're quite sad that we won't be able to blast through the game with friends, but it's going to be interesting to see what Treyarch does have planned. It better be good!
