The Tomb Raider Underworld: Lara's Shadow downloadable content is now available on Xbox Live, giving players a chance to play as Lara Croft's harder, better, faster, and stronger doppleganger.

In an interesting twist on Underworld's main story, Lara's Shadow gives us a chance to see what Miss Croft's cleverly crafted copy would do if she were in control of here own actions. From the launch trailer, it looks like it would do exactly what Lara was doing anyway, only much, much better.

Lara's Shadow is now available via Xbox Live for 800 Microsoft points.
