Tomb Raider: Underworld - Lara's Shadow

Lara's Shadow is the second and final add-on for Tomb Raider: Underworld and just like the first add-on, Beneath the Ashes, exclusive to the Xbox 360 version of the game. You play as the Doppelganger, an evil duplicate of Lara, and the events take place in a new level after the ending of the original game. The Doppelganger has shadow powers which give her super-human speed and strength. They can be used for a certain amount of time before the shadow meter runs out, which refills automatically after a short amount of time.
