Eidos has teamed up with Microsoft to offer two Tomb Raider: Underworld levels available only on the Xbox Live Marketplace. Xbox 360 owners can grab Tomb Raider: Underworld - Beneath the Ashes at Christmas with Tomb Raider: Underworld - Lara`s Shadow following in early 2009.

The new DLC may make it more difficult for gamers with multiple consoles to decide which version of Tomb Raider: Underworld to purchase. It`s great for Eidos considering that the 360 will have exclusive DLC and the Wii version has controls tailored to the Wiimote. It will be interesting to see if Sony gets its own exclusive features or content adding more incentive for gamers to buy multiple copies for different special features. Eidos will also be offering a demo through XBL in October so keep an eye out for it. Tomb Raider: Underworld is due out in November in North America.
