Black Ops: Annihilation launches on XBLMP

The third map pack for Black Ops, Annihilation, has launched on Xbox Live.

The pack, which comes in at a chunky 766Mb to download, is now yours for 1200MS points. You can get it at the game's page on the console Marketplace at the moment, as well as the online marketplace to queue it to your console here.

For your 1200 MS points, you'll get four new competitive maps in the form of Hangar 18, Drive-In, Silo and Hazard, as well as new zombie map, Shangri-La.

There's a video of the pack here. It'll launch on PS3 and PC once the timed exclusivity ends on 360.
