Press Select on controller two to advance frame by frame. Set the controller two type to "Camera" to allow it to change camera angles, while using controller one to zoom.
Controller two can be used to set the camera angle to view the fight from below ground level. The floor will be invisible. This particular camera angle can only be set while the game is paused. Press Start to continue playing using this unique view.
Press X + Triangle + Circle + Square + Select to re-display the options menu; or press Start to play without the energy gauges and scores.
To fight Sho, the true last boss of the game, finish the game without using a continue on the normal difficulty level or harder. Sho has Kayin's, Eiji's, and additional moves. The game's real endings will appear after Sho is defeated.
When the game is finished on a difficulty below Normal, Gaia must be defeated. If Gaia is beaten, a "desperation" move will be received. If the game is finished on a difficulty of normal or harder, and Sho is reached by not using any continues and beaten, a secret move will be received. Continues may be used while fighting against Sho.
