The latest episode of Xbox LIVE's Major Nelson Podcast has word that a new First Strike map pack will be released for Call of Duty: Black Ops on February 1, 2011, notes Joystiq, saying this will be a "timed exclusive," so this will not be available for other platforms right away. They say the pack will include a zombie map called "Ascension" as well as four competitive maps: "Discovery" set in an Antarctic research station, "Kowloon" set on the rooftops of Kowloon, "Berlin Wall" featuring a battle at Checkpoint Charlie, and "Stadium" set in an American hockey rink.
