weapon, except for grenades. Aim at an opponent, then press A + B

Press A + B at the same time to unleash powered-up versions of weapons in single player mode. In order to do this trick you must have fifteen of that type of weapon. Note: Press Z when guided missiles are under your control to fire a blue laser.
