While the headline could have been "get a taste of Lara Croft" or something that would've driven up the inadvertent porn-seeking traffic, we didn't feel like insulting your intelligence, o beloved readers. So here's the straight, unsexy news: a playable demo of Tomb Raider: Underworld is now available on Xbox Live.

The demo was announced by Eidos last week. Major Nelson confirmed this morning on his blog that it had gone live. It's available in all regions and allows you to play a portion of the Thailand level of the full game.

A PC version of the demo will be released on Friday. No word on whether PS3 owners will get one as well, though there's a few weeks to go. Underworld is set for a November 18th release.
