As was widely suspected yesterday, Call of Duty: Black Ops will expand this month with an all-new map pack, due out first on Xbox Live.

　　Titled Annihilation, the new add-on for Treyarch's blockbuster hit will arrive on Xbox Live on June 28. The content will follow the precedent set by past add-ons First Strike and Escalation, in that it will be composed of four fresh multiplayer maps and one zombie level. Fight on a golf course in Black Ops' third add-on.

　　The new killing spaces included in the downloadable content are Hangar 18, Silo, Drive-In, and Hazard. Unfortunately, no further information was offered concerning the maps. The zombie level is titled Shangri-La, described by Activision as "an exotic and mysterious map."

　　Activision did not set a price for the Annihilation DLC in its announcement today, but previous map packs debuted for 1,200 Microsoft points ($15). There was no mention made of when the content will arrive on the PlayStation Network or for the PC.
