The obligatory month of Xbox 360 exclusivity is up, so Call of Duty: Black Ops players on PlayStation 3 and PC can now download the new Annihilation downloadable content for $15.
As has been said many times before, this pack includes the Hanger 18, Drive-In, Silo, and Hazard maps for competitive multiplayer, in addition to the new zombie level Shangri-La. That last one does look legitimately fun, and that's coming from someone who is mostly burned out on both zombies and this style of shooter.
For the occasion, Treyarch is activating double experience points across all Black Ops versions. Gotta get that prestige, or else the kids won't think you're cool.
