It looks ok, but there are so many better shooters already out there -- Call of Duty, Halo, Gears of War, Bioshock, Half Life, etc. Not that the first one was a bad game, it just wasn't a great game.
This fall in particular is packed with good games -- LittleBigPlanet, Gears2, Rock Band 2, Guitar Hero: WT, Bioshock PS3.
