The third downloadable add-on for Call of Duty: Black Ops, "Annihilation," hits next week (for Xbox 360, that is), bringing with it four new maps and one new zombie-slaughtering "experience." Want to see? Watch that video.

You'll get a new peek at those maps—Hangar 18, set in a highly classified military base of Area 51; Drive-In, a colorful, '60s era drive-in theater; Silo, a Soviet nuclear missile site; and Hazard, a Cuban golf course—plus Shangri-La, an exotic jungle map teeming with zombies and zombie monkeys. Hear what developer Treyarch has to say about those maps right here.

"Annihilation" for Black Ops hits Xbox Live on June 28. Expect it to hit the PC and PlayStation 3 later, after Microsoft's window of exclusivity closes.
