The Chronicles of Riddick films weren't popular among critics, but the video game adaptation actually scored solid reviews. Steam has cut 75% off The Chronicles of Riddick: Assault on Dark Athena (a sequel to TCoR: Escape from Butcher Bay, but it includes the original campaign). Meanwhile, RTS fans might want to swing by Impulse to pick up the Dawn of War Collection at half off, and Microsoft is offering Alpha Protocol for 50% off.
