At the EA DICE event during GDC last week (the same one where we saw Battlefield Heroes and Bad Company), we had a chance to watch a trailer and a one-level walkthrough of Mirror's Edge, a stylistic first-person game reminiscent of both Parkour and the Bourne movies. DICE went for a more realistic perspective by slightly tilting the camera back and forth depending on how fast you move.
The level we saw had the character jumping over fences, sliding under pipes and traversing through and over buildings like a crack-addicted monkey looking for its next fix. Items and platforms turn red while you run to provide context clues for what you can use to keep your momentum going and move forward (e.g. a swinging rope you can grab jumping off of the side of a building).
As for combat, it seems the point of the game is rather nonviolent; when our hero did steal a gun from an opponent, she quickly disassembled it and kept running. The game looks promising, but we can't help but wonder how it would have looked if they used the same camera/blur effects and moved the camera back to third person.
