Hint: Bukaryu: Super combo:
Press Up + Square, Forward, Circle(5), L1. This will take a large amount of health from your opponent. It can kill someone if you do damage before you execute it. Sometimes during the Circle part of the combo, the opponent will turn around and thus it will not work.

Hint: Jenny: Extra damage with Beast grapple:
When in bat form, when you grapple, hold Triangle to do double damage.
Justin.

Hint: Mitsuko: Wall slam attack:
Keep pressing Down + Circle, then when you want to do the move press Down/Forward + Circle. This does major damage if done frequently. It is most effective in survival mode because the opponents will barely have time to attack you.

Glitch: Jump out of arena:
On the second (if you won) or last (if both opponents won once), knock someone out of the arena. Just before the person hits the ground out of the arena, press Up + Circle. You should jump out of the arena. If not, you were either too far from the edge, at the edge, or did not do it at the correct time. You must do it close to the edge, but not on it. On some arena's you will catch on fire while doing the winning pose.
