Activision announced via US Playstation Blog that the third Black Ops map pack Annihilation, will hit the PS3 on July 28th. The map pack launched first on Xbox 360 about a month ago due to a three-year exclusivity deal between Microsoft and Activision.

The pack contains four new competitive multiplayer maps and one new zombie map, Shangri-La. Activision has yet to announce a release date for the PC version, but chances are it will follow shortly after the PS3 version.
