Just been having a look at the demo for WARP, which is a PSN/XboxLive title.
It's quite well made really.
Storyline is minimal but serviceable - You're a captured alien, you have to escape and evade recapture/death by avoiding or destroying the things you encounter.
Hm, it's like a puzzle oriented action/stealth game.
Pretty fun.
Have a look at the trailer, I reckon a few of you might want to play it.
