Atari’s Chronicles of Riddick: Assault on Dark Athena demo is available on Xbox live, and it’s a slim 638MB, so get it while it’s hot.

Dark Athena is the sequel to the award-winning Xbox game, Chronicles of Riddick: Escape from Butcher Bay. You’re Riddick, voiced by the always entertaining Vin Diesel, in what’s pretty much a futuristic sci-fi prison stealth action game.

The game kicks ass and you will too when you watch our trailer here.

Go get it.
