The Chronicles of Riddick: Assault on Dark Athena is an action, stealth, first person shooter set in the futuristic, sci-fi world of the Riddick film saga. The game is a follow-up to 2004's The Chronicles of Riddick: Escape from Butcher Bay where Riddick must now flee onboard the Dark Athena, following his harrowing escape from the notorious Butcher Bay prison. During the adventure, he must escape the predatory Merc-ship Dark Athena using stealth and action to overcome its merciless crew and challenge the nefarious Captain Revas.
Due to the fact that the first game wasn't backwards compatible with the Xbox 360, developer Tigon Studios decided to fully remake The Chronicles of Riddick: Escape from Butcher Bay and include it with the release of the sequel.
