Mirror's Edge..
 

I have died like 1,000,000 times but it is super fun..

is this any good?

'sokay. The gameplay is fun but doesn't really always work like it should, the story's just kinda there as an excuse for you to jump around rooftops (and yes I know the same can be said for just about any game, but they could at least make an effort), and the indoor sequences kind of suck.

It feels more like an extended tech-demo, waiting for someone else to come along and incorporate it into a more complete game. Still, though, it's worth renting.
