Instructions
Inflict heavy damage on your opponent during the Inferno match. This damage will steadily raise the temperature of the ring, which has to be 500 degrees Fahrenheit or hotter before you can throw your opponent out of the ring.
Use the left control stick when prompted to drag your opponent to the ropes. This may take a few tries, as he will have to be severely weakened for this to work.
Press the "Circle" button and the direction of the nearest ropes (i.e., push the control stick left if you're close to the left side of the ring, right if you're close to the right side of the ring, and so on) to perform an "Irish Whip" maneuver. This will throw your opponent over the ropes and out of the ring.
