At this year’s E3, developer Treyarch recently showed off some of the explosive single-player campaign for the upcoming Call of Duty: Black Ops. set in several decades during the height of the cold war between the United States and Russia. While the campaign will take players from the Viet-Cong tunnels of Vietnam to snowbound Russian mountaintops, the studio has been tight-lipped regarding the game’s multiplayer. A new teaser trailer has been released, revealing several of the maps, weapons, perks, and all the Call of Duty goodness fans have come to expect. Our excitement is best summarized by one thing: crossbow. Other added features include a recording functionality, allowing players to save some of their best (or in our case, worst) moments.

Call of Duty: Black Ops releases November 9, 2010.
