After starting a new game, go to the arena, lose 10 times to the first AC then win. You must do this with what you start with. Do this to all AC and you will get the ultimate weapon that will kill any of the opponents in one hit.
Well this code isint exactly wrong, if you beat the #1 AC then you win a hand-shaped weapon that is very powerfull. it shoots 5shoots at once and kills most story mission enimes fast and has lots-a-shots!
