Tomb Raider: Underworld: Lara's Shadow

In Lara's Shadow, the player takes control of the Doppelgänger. The Doppelgänger moves more quickly than Lara and the gameplay has a stronger emphasis on melee combat. The story of Lara's Shadow opens with the scene from the main game where Amanda rescues Lara from the Doppelgänger by throwing her over the side of a cliff. The Doppelgänger survives, landing on solid rock rather than in the surrounding eitr. When she regains consciousness, she proceeds to find Natla. Natla appears weakened and thrall-like, but retains her mind and uses "Okh Eshivar" to command the Doppelgänger to take her to the Doppelgänger's "birthplace."
