This one website is in their open beta stage of a Mirror's Edge flash game. I haven't played the actual console game, but I will soon. The beta of this though is more less a training/feedback level, also helping get players familiar with the controls. This thing is awesome, and also in third person. I do recommend trying it, especially if you haven't rented the console Mirror's Edge, but are wanting to.
