For generations, stories have been told of the fearsome weapon of the Norse god Thor. Legend holds that he who wields the hammer has the power to smash mountains into valleys and the strength to destroy even the gods. For more than a thousand years it has existed only as a myth…until now.

In an ancient ruin on the floor of the Mediterranean Sea, Lara Croft uncovers proof of the Norse underworld and the mythical hammer. As she attempts to unravel the secrets behind these myths, Lara’s perilous journey leads her toward a forgotten power that, if unleashed, could lay waste to all civilization.

Offering entirely new content specifically designed to extend the Tomb Raider: Underworld experience, Tomb Raider: Underworld – Beneath the Ashes and Tomb Raider: Underworld – Lara’s Shadow will deliver two very different single player gameplay experiences. Tomb Raider: Underworld – Beneath the Ashes takes place after the Underworld story has finished and will feature an incredible new environment to explore, additional secrets to unlock and different enemies to fight. Tomb Raider: Underworld - Lara’s Shadow will introduce players to a new kind of playable character and create a unique Tomb Raider experience.

The first new chapter, Tomb Raider: Underworld – Beneath the Ashes, will be available for download exclusively on Xbox LIVE Marketplace this Christmas. Tomb Raider: Underworld – Lara’s Shadow will follow in early 2009.
