You can change the way attacks, throws, and counters are performed by being near a wall. Not all moves will change though. 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 be 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: one of kasumi's throw moves that results in her jumping up on top of the oppents head and giving several downward kicks to them in the head as go to the ground. When preformed with kasumi's back to a wall. Results in her grabing the oppents arm slaming the front of their body into the wall 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 counter moves I only saw a difference when your characters back is to the wall and are countering a mid punch.
