The initial Atari offering on Impulse that sports the highest profile is The Chronicles of Riddick: Assault on Dark Athena. A sort-of sequel to Escape from Butcher Bay, Assault on Dark Athena includes an enhanced version of the original stealth-FPS by StarBreeze Studios, as well as a new adventure that takes place aboard mercenary ship Dark Athena. Assault on Dark Athena was originally released in April of 2009.

In other Impulse news, casual gamers can check out developer Digi Ronin's new puzzle game, Mary Kay Andrews - The Fixer Upper, also available this week. In the game, you play a Washington lobbyist Dempsey Jo Killebrew who flees to the small town of Guthrie, Georgia after being framed for a crime and getting fired. Bring your boss to justice while renovating a recently-inherited Victorian mansion. Just like real life!

The Chronicles of Riddick: Assault on Dark Athena and Mary Kay Andrews - The Fixer Upper are available on Impulse for $19.99, though Riddick's latest adventures are only available to customers in North America.
