Activision Publishing announces the release of the Windows and PlayStation 3 editions of the Annihilation DLC for Call of Duty: Black Ops, adding four new multiplayer maps and new zombie content to the military shooter sequel. "Annihilation delivers four of the best Black Ops multiplayer maps, and a mind blowing new Zombies experience with Shangri La," said Treyarch Studio Head, Mark Lamia. "With Annihilation, fans are really going to have a lot of fun continuing to play Black Ops online for a long time to come." Here's a reminder of the contents of the DLC:

• "Hangar 18," buried deep within the military black site Area 51, where gamers will battle through experimental weapons labs, the SR-71 test hangar and a mysterious autopsy room.
• "Drive-In," where players engage in close-quarters combat through a 1960s drive-in theater, complete with snack shack and a classic arcade.
• "Silo," a massive multilevel battleground tucked within a super-secret Soviet era nuclear missile site.
• "Hazard," perched on the verdant Cuban cliffside, where gamers traverse a coastal golf course fit for a dictator. This is the only set of links where the hazards shoot back.
• "Shangri-La," the all-new Zombies experience, which transports players to a mythical paradise overrun with the undead. Face off against new species of zombies and navigate a treacherous labyrinth of underground caverns, all set within a lost jungle shrine.
