Tomb Raider: Underworld's not in stores yet but after it is released and you do finish it, you won't be done yet. Eidos has revealed that the Xbox 360 version will have two episodes of exclusive downloadable content.

The first chapter of DLC, Beneath the Ashes, will be available for download this Christmas. It will take place after the events of Underworld and feature new enemies and a new environment. The second chapter, Lara's Shadow will be released in early 2009. Interestingly, Shadow will feature "a new kind of playable character."

New kind, eh? I thought the "attractive, curvy British gal treasure hunter" was a pretty good kind of playable character, to be honest. Would backflips be as fun without the ever-present danger of knocking yourself unconscious with your character's Double-F knockers? We shall see. Maybe it'll just be an "evil Lara" with blonde hair.

Underworld will hit stores on November 18th for Xbox 360, PS3, PS2, Wii, Nintendo DS, and PC.
