I finished "Bulletstorm" last night. I'm surprised no-one else here is talking about it! It's a ton of fun. The graphics and settings are gorgeous. The game play really is different from your usual shooter; I don't know how I'm gonna go back to Halo where I can't leash the bad guys, send them flying through the air towards me in slow mo so I can shoot them better or kick them into a spike wall
The dialogue is also pretty funny. Not as good as the hype was suggesting but it's definitely entertaining. The story is much more interesting than something like Gears of War.
