Press X when choosing a fighter at the selection screen.

Get your opponent's life to a certain point (red zone). Then, press Down + A + X or Up + X + Y. This is useful when your goal is to break that person's arm.

Hint: Break leg:
In order to break your opponent's leg, he must be one hit away from defeat. Then, press Right + B + Y.

As soon as your opponent gets back on his feet, execute a punch combo. You only have a small amount of time to hit him when he is not blocking you. Kicks do not work as well, as they usually duck faster and can sweep you on the ground. A good combo would be X, Y, X, Y.

Survival mode allows you to gain 1,000 CDP points on your first victory, and it increases by 250 points with each win. However, the more fights you win, the tougher your enemy becomes.
