Riddick better get all those dark, monotone soliloquies out of his system before assaulting the Dark Athena crew on April 7 in North America, and April 24 in Europe. Atari sends word that The Chronicles of Riddick: Assault on Dark Athena will be available for PC, PS3 and X360, with demos releasing in March for the console versions.
Don't forget that Dark Athena also comes with an enhanced Escape from Butcher's Bay, so there'll be plenty of Riddick packed onto the disc come April.
Update: Big Download has word that a PC demo is in the works. No word of when it'll release, though.
