Atari released a demo for The Chronicles of Riddick: Assault on Dark Athena on Xbox Live yesterday (available for Gold users) and a demo on Playstation Network is coming soon. The demo features single player gameplay on the main deck of Dark Athena and will allow players to take control of the slave drones a band of mercs are creating on the ship. No firm date for the PS3 demo has been announced and there seems to be no plans for a PC demo at this time.
