For those still waiting on the Black Ops: Annihilation DLC for PC and PS3 only have to wait until July the 28th before they can get their hands on the 3rd DLC pack.

Included in the DLC are four maps and one zombie map and here you will find the official site and trailer

"Jump in to battle on Multiplayer with: "Hangar 18," located in the highly classified military base of Area 51 where you will fight through experimental weapons labs, the SR-71 test hangar, and a mysterious autopsy room; "Drive-In," close quarters combat through a 60's American Drive-In theater, whose last showing was "Attack of the...", complete with a snack shack and a classic arcade; "Silo," infiltrate a massive secret Soviet nuclear missile site under construction in this multilevel battleground; and "Hazard", play through this coastal golf course fit for a Dictator, on the cliff sides of Cuba, where stocked clubhouses and manicured fairways meet snipers hidden in sand traps.

Zombies are back in "Annihilation", as players unearth the mysteries of "Shangri-La," a legendary shrine lost in an exotic jungle, where new undead species lurk within a treacherous labyrinth of underground caverns. Navigate through deadly traps and solve the dark secrets buried within the shifting walls of this zombie infested temple."
