A playable demo for The Chronicles of Riddick: Assault on Dark Athena has been released on Xbox Live. Gold account holders can download it now, though Silver account users will have to wait for a couple of days to be able to download it.

Dropping in at 639MB, the demo offers a sample from the “Athena Main Decks” level, implying that it is probably taken from the new campaign rather than the remade Escape from Butcher Bay campaign that is also featured in the game.

A PS3 demos is expected to drop on PlayStation Network sometime this month. PC users will also see a demo, though no release date estimate was givne.

Developed by Starbreeze, the full game will hit PC, PS3 and Xbox 360 on April 7.
