Have you? 'Blacksite: Area 51' demo

I meant to ask this a few weeks ago, but forgot.

Have you played the 'Blacksite: Area 51' demo available on Xbox Live?

GOOD LORD, it's scary cool and WAY too short. But, if the final game is anywhere near as cool as the demo (minus the chuggin' graphics), this will be the next big hit on the 360.
