this is not really a cheatcode more of a move you would want to use when you are in danger and close to dying. to use this move you should have al least 50 arts.first jump up and press the melee button to use a stun attack then press the R2 button and hold then press and hold the shot button and melee button at the same time if done correctly you should use a bullet dance that does charged up shots in slow motion and you will be unstopable. and also you should have no sheild left.
