Though Call of Duty: Black Ops' Cold War setting is a new feature for the series, one element of the game will stay true to the franchise's norms: the game's campaign will only be a single-player experience. Speaking to MTV, Treyarch studio head Mark Lamia explained, "single-player is the epic, cinematic, seat-of-your-pants thrill ride that you star in," while the game's cooperative offerings will be packaged in completely separate "unique co-op modes."

Sounds fairly reminiscent of Modern Warfare 2's Spec Ops missions, though Lamia quickly clarified that Black Ops' co-op mode will be "different" from that of the last game in the series. Could we possibly see more zombies added to the mix? Hopefully, we'll find out more when we check out the game at E3.
