The trailer to the upcoming addon "First Strike" for Call of Duty: Black Ops has just been released. The new addon features four new multiplayer maps for the video game: Berlin Wall, Discovery, Stadium and Kowloon, and a new Zombie. From checking out the video myself in high defintion, the new maps look incredible. Expect this First Stirke addon to be downloadable on February 1st for only $15. The graphics one the new maps are quite incredible, I think they live up to the Call of Duty name quite well.
