Can you beat life?
Perhaps only by dying. Perhaps you can only beat toribash by quitting.
Naw, you can't beat this game. It's not a single player game with a campaign. Same applies to most MP games. Can you beat tf2? Can you beat Garry's mod?
I guess some goals you can have are get to custom belt, get you tori totally customized how you want, meaning you don't need one of every force, just one of the force you like.
Join a clan....
Have fun.
Most people get tired of the game after a while though. Like now that I have my personal goals achieved, there isn't much point to tb, it's just for fun.
