We've heard scant details on the upcoming Treyarch title Call of Duty: Black Ops[/url], but a new magazine feature is letting loose with much more information than we had before. The latest Official Xbox Magazine (via WePlayCOD ) breaks down the new additions. As expected, players will spend at least some of the time fighting the North Vietnamese, but the lead character has a secret agenda as well. In the trek through Vietnam, the player will enter water engagements with a trusty knife, provide intel from an SR-71 Blackbird, and even take control of a helicopter. The spread also shares more details on the multiplayer aspect. The co-op mode will feature separate levels, built specifically for it. Treyarch strongly hinted at a beta, and said they'll be improving this game's multiplayer based on player feedback from World at War. The developer also promises improved matchmaking, along with an enhanced Create-a-Class for added character customization.
