Press X while playing the game to bring up the team menu. Hold Select and press the Left Analog stick up and rotate it clockwise three times, then immediately rotate it counter-clockwise 3 times while continuing to hold Select. NOTE: The character will run while the code is done and there will be a new icon under the log icon in the lower right hand corner of the screen. Highlight the icon then select it. Doing so will bring up the cheat menu which unlocks all weapons and gives you unlimited health and weapon energy. It also gives you the ability or warping to the last level and level select.
