Activision have let us know when PC and PS3 players can arrive at the Call of Duty: Black Ops "Annihilation Map Pack" DLC party, fashionably late, as usual.

“With Annihilation, the team at Treyarch and Activision has shown its continued commitment to bringing new and unique content to our fans,” said Treyarch Studio Head, Mark Lamia. “Players are getting four of the best multiplayer maps to date with Hangar 18, Drive-In, Silo and Hazard. They also get a brand new dose of thrills in Shangri-La, our latest Zombies offering, packed with deadly traps and dark secrets buried within the shifting walls of an ancient and mysterious temple.”

According to ATVI local, you'll be able to grab the content on the 28th of this month. We've hit them back for specific pricing, so watch this space for details.
