Things get pretty stupid in the funniest way. You can shoot, grab a frying pan, smack someone with a high heel, or just throw a phone at whoever's nearby. Baseball bats are fun too, especially when someone goes flying across the room. The ragdoll physics make every fight a little unpredictable.
The full version is already unlocked, and there's plenty of random stuff to mess around with. It's the kind of game I play just to have a laugh rather than worry about winning. I do wish there were more open maps where you could freely explore, pick fights, and try out all the ridiculous weapons.
