Raging Breath Cheats (PlayStation 2)

Beat the game with each of the four characters in Normal or Hard mode. After that, a new
character, Aria/Iria, will be available for you to play in Story mode.

To unlock characters in Duel mode you must beat the game with at least one character on
any difficulty. After that, you get the option to save. Save the game and then the next
time you start a Duel game, you will find that most of the monsters you encountered
previously will be characters that you can use in Duel mode.
