It's your basic first-person shooter. The gameplay looks very similar to Gears of War, at least from what I've seen. The difference is that you can control time by slowing it down or even stopping it, kinda like Prince of Persia: Sands of Time. The function is also available in multiplayer mode through the means of a time bomb, but I think it can be deflected with a time shield.
GameSpot has a preview of it and the demo from E3 on the website. Anyway, check it out if you enjoy playing FPS games.
