Nexuiz headlines this week's Xbox Live update.

The fast-paced arena shooter draws its inspiration from the classic Quake, with CryEngine 3 powered visuals and a futuristic Victorian-influenced art style. Download it for 800 MS Points (£6.80 / $10).

Full retail games Harry Potter and the Deathly Hallows Part 1, Madden NFL 12 and Shadows of the Damned are now available for download, as is 'The Lost Archive' DLC for Assassin's Creed: Revelations and a demo for FIFA Street.
