In the Subway Train on Level 2-Nano, you can use this technique to get huge combos. Simply push an enemy into one of the corners between the seats of the train and the wall, and then uppercut him (with R2). Now use regular attacks (with X) to keep him in the air. Time your attacks, and you can keep him in the air for as big of a combo as you want.

In 2-player mode, press X and SQUARE at the same time to get into a stance. Then have your teammate come next to you, face you, and then press X and SQUARE at the same time. You will perform a special team attack where you are thrown into enemies, hurting them.
