Obtain each character's "Ultimate Weapon":
1. Finish the "Edge Master Mode".
2. Let the credite run.
3. The game will return to your character standing on Spain.
4. Travel to the countries adjacent to Spain and defeat the opponents there again.
5. The Ultimate Weapon will be randomly hidden in one of those countries. You will be given your weapon when you win in the stage where it was placed. If you lose, the weapon will move to an random adjacent location.

Alternate endings:
There are two different endings (the sequence when you finish Arcade Mode) for each character. One of these plays automatically. Here's how to see the other one: Finish Arcade mode as anybody then wait for the ending to play. When it goes widescreen, rotate the D-pad (any direction) and randomly press the attack buttons. If it works, a different sequence will play.
