You play as "crazy-haired emo with an over compensating sword #1" and you're trying to stop "crazy-haired emo with an over compensating sword #2" from summoning a meteor to destroy the earth or some crap like that. And in the meantime, #2 whines about about his mutant mother, acts excessively fruity and kills #1's girlfriend while in the meantime #1 breeds giant, yellow, inbred birds. Oh, and there's the token black guy who never stops cussing (although admittedly that last part's a bit cool)
Yeah, you'd have to be really stupid to spend money on a game like that.
