Eidos has announced today a deal between themselves and Microsoft to bring two exclusive downloadable chapters to the Xbox 360 starting this winter. The two chapters will contain around six hours of gameplay to the upcoming game.
"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."
Beneath the Ashes will be available this Christmas with Lara's Shadow following in 2009.
