If you haven't seen it yet, I strongly recommend checking out the latest trailer for Mirror's Edge. This game is being put together by Battlefield series developer DICE, and I think it looks awesome. Just watch:
Visually, this looks to me like a cross between Portal and Assassin's Creed, but with skyscrapers, gunfights, and much more visceral, first-person free running. The trailer also has nice cinematic music, although I don't know if it'll actually end up in the game.
Mirror's Edge is apparently coming out late this year the PC, Xbox 360, and PlayStation 3, and I'm really looking forward to it—especially after having read Shacknews' first impressions, which tell me DICE has worked hard to come up with innovative gameplay mechanics.
Also, I saw on Joystiq yesterday that the game will be based on Epic's Unreal Engine 3.0, so the PC version should hopefully scale reasonably well on today's machines. I can't say as much for Assassin's Creed, which I had to play at 1440 x 900 on my own machine (which packs a Core 2 Duo, GeForce 8800 GT, and 4GB of RAM) to get smooth frame rates.
