During Ayane's story mode when you get up to the stage where you vs Kasumi, instead of falling down the large gap in the snow lvl where you vs her, you stay on the where you are and beat her there. So instead of doing a fire ball you'll do this kind of ice blast thing.

With each of the 15 fighters again, you must obtain their last unique 'rare' item, and upon doing so, you unlock all costumes, cg gallery and the DOA3 booster pack (for those that don't already have it). My thanks to the DOA boards.
Vertical pain
You can change the way attacks, throws, and counters are performed by being near a wall. Which all characters can do as in the moves that are throws. The attack and counter moves do not change for all characters when near a wall. This involves the oppents back to be facing the wall or your charcters back to be facing the wall and you have to fairly close to wall with some of them and lined up to the wall in a fairly straight line. Refer to command list for each character at the pause menu to see how to perform each move. EX: kasumi's nagi (throw move)that results in her jumping up on top of the oppents head and gives several downward kicks to them in the head as go to the ground. When preformed with her back to a wall it becomes adachi-shizuka. Which results in her grabing the oppents arm slaming the front of their body into wall the and finishes it with a kick to the middle of their back. With attack moves I only really saw difference in the moves. That involve the character to do jump flip backwards when their back is to a wall and then at the right momment in the jump pressing one of the attack buttons. For the throw moves I only saw a difference when your characters back is to the wall and are countering a mid punch.
