Instructions
Select "Play" on the Main Menu, then "One on One," then "Inferno Match." This match-type can only be played one on one.
Execute moves on your opponent to raise the temperature to 500 degrees Fahrenheit. The temperature meter drops steadily, so use power moves to get the temperature up quickly.
Slam your opponent near the ropes so you can easily control him when he stands. Winning this match is much quicker when you don't have to drag him far while the temperature is dropping. Lift your opponent with the "Y" button to take advantage of his groggy state.
Strong grapple with the "B" button and the Left Analog stick. Drag your opponent to the ropes while grappling with the Left Analog stick and the "burning" animation should play, causing you to win the match.
