If you want countless new hours of fresh game play in Call of Duty Black Ops, then the just-released Annihilation DLC pack is what you need to purchase on Steam: four new varied maps to play on, plus a brand new zombie experience that appears to be the cherry on top for this new DLC pack. Below are details for all the new goodies introduced by the Annihilation DLC pack:

• “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.

You should head over to Steam to download this DLC pack and prepare for a hot weekend this weekend (29th-31st July) because Treyarch will be hosting a cool Double XP event!
