Meet Lara Croft's doppelgänger, a (sorta) brand new playable character in Lara's Shadow, the newest expansion to the Tomb Raider Underworld franchise available for exclusive download on the Xbox 360. Imbued with "shadow powers" and Prince of Persia-like acrobatics and agility, this could perhaps be the shot-in-the-arm the series' gameplay needs to change things up a bit.

Lara's Shadow hits Xbox Live Marketplace March 10 with the price tag of 800 MS points ($10) -- just like Beneath the Ashes DLC that's currently available. Full details for Lara's Shadow after the cut.
