This game is a few months old, but I just finished it and LOVED it.
If you know nothing about this game - watch this first (lots of swearing) - http://www.youtube.com/watch?v=SH0KH9F4He8
If that didn't make you laugh, then Bulletstorm might not be for you.
Me? I laughed through the whole game. The dialogue is hilarious. The dick jokes aren't as prevalent as the youtube clip makes it look - they're spread out throughout the game. But, when they come up they are pretty well played.
Beyond the language, the gameplay is very fun. The weapons are fun and offer a lot of variety and the whip is pretty damn cool.
You earn points which you use to upgrade weapons and buy ammo and you get extra points for doing special kills - such as whipping a guy which pulls him towards you in slow motion and then kick him into a wall of busted metal which he gets impaled on......yeah, it's like that!
