Xbox Live Update: Black Ops Annihilation DLC

Leading the charge this week is the Annihilation map pack (1,200 Microsoft points, or $15) for Call of Duty: Black Ops. The content brings four new multiplayer maps and one new zombie level to the Cold War-era shooter.

The new killing spaces included in the downloadable content are Hangar 18, Silo, Drive-In, and Hazard. The zombie level is titled Shangri-La, described by Activision as "an exotic and mysterious map."

Debuting tomorrow on Xbox Live Arcade will be three new games, the first of which is NaturalMotion's Backbreaker Vengeance (1,200 Microsoft points, or $15). Whereas the original Backbreaker focused on simulation gameplay, Vengeance will include arcade elements based on NaturalMotion's iOS release, Tackle Alley, which has sold more than 1 million copies.

Though it does not feature officially licensed NFL teams or athletes because of EA Sports' exclusivity deal, NaturalMotion touts Backbreaker's realistic play experience, due to the flexibility of its game engine. Backbreaker Vengeance will offer an expanded version of the Tackle Alley iOS title, featuring "hundreds" of challenge levels.

The other two new XBLA games debuting tomorrow are Marvelous' action role-playing game Half-Minute Hero: Super Mega Neo Climax (800 Microsoft points, or $10) and Namco Bandai's Galaga Legions DX (800 Microsoft points, or $10).

Gamers looking to pick up a full Xbox 360 title this week from Xbox Live have three new titles to choose from via the Games on Demand hub. Capcom's Bionic Commando ($20), Gamecock's Legendary ($25), and BlazBlue: Continuum Shift ($30) are all now available as full-game downloads.

Lastly, gamers can get their hands on NCAA Football 12 via a new demo released today. The sampler lets gamers try out EA Sports' latest college football simulator in two matchups: Alabama vs. Florida State and Oregon vs. Texas.
