With the change of hardware from Neo Geo to Atomiswave, the number of buttons is now increased to five. In addition to the standard four attack buttons used in the previous games, a fifth button is now added which is used to activate the Heat Mode. Heat Mode will cause the character to blink red and increase their offensive strength, with the side effect being that the character's health will begin to drain. The player will return to normal after getting hit by the opponent or by pressing Heat Mode button again to deactivate it, and the player must wait until you lose a round to activate it again. The player cannot use Heat Mode when the life gauge is low.
