I got over this game when I played the demo. Don't get me wrong, it upped the anti on Duke Nukem features, it also feels a little like Shadow Warrior, it's got the 3D Realms cheese factor. The graphics look sort of like greased rubber. And for the swearing - the F word a couple of times doesn't make a game more mature, it only adds to the cheese level. Don't get me wrong, I say the F word like the word "I" or "the". Oh and the gravity? We've played Descent. Probably a good game for early teens, though - if they can get it.
