Posing Characters
After you win a battle, you can zoom in, out, and rotate your character. Just hit the L1 button when the replay is over and your character starts to pose. Now you can use the left stick rotate, and the right stick (using the up and down of it) to zoom in and out. NOTE: This does not work for every mode of play like tag battle, or team battle. It does work for story and vs. Just play with it.

Game Hint:
In survival mode open the cd lid after the game has loaded.....Now when you KO your oponent he wil not be replaced but he wil stay on the ground.
Now do a down move to get up to 3 items out of one oponent....close the lid and let the game load again...Open the lid ko victim down move 3 times close lid ...this way you can ern 3 times as many items than you normally would.
