Thanks to a post on Major Nelson’s Blog, we now know that a Tomb Raider: Underworld demo has been unleashed unto the world, available on Xbox LIVE right now in all LIVE regions. The tag line reads; “Explore everything. Stop at Nothing.” A further bit of blurb describing the motivation behind the game is as follows:

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

Indeed. The full game is out on almost every platform November 18th in the US and November 21st in the UK and Europe.
