Activision announces the Annihilation content pack will launch first for the Xbox 360 edition of Call of Duty: Black Ops on June 28th, before presumably launching for Windows and PlayStation 3 at some point after that. The DLC will add four new multiplayer maps and more zombie action to the military shooter sequel. "With Annihilation, Black Ops fans will get four exciting and unique multiplayer settings with Hangar 18, Drive-In, Silo and Hazard," said Treyarch Studio Head, Mark Lamia. "Players will also enjoy an all-new Zombies experience, Shangri-La, an exotic and mysterious map filled with deadly traps, dark secrets and innovative gameplay that will challenge even the most daring Zombie hunters."
