Eidos Interactive announced today that Tomb Raider: Underworld, the latest installment in the Tomb Raider franchise developed by Crystal Dynamics, has been released as part of the Classics range for Xbox 360 and Platinum Hits range for PlayStation 3. In Tomb Raider: Underworld, using every weapon in her arsenal - from her signature dual guns and expanded kit of archaeological tools to her own physical prowess and the environment itself - Lara leads a quest that circles the world to uncover the secrets of the Norse underworld and a forgotten power, that if, unleashed could lay waste to all civilization.
