During a duel, you can punch and kick your opponent, use special attacks, or employ a "taunt" to restore some health. The first combatant to win the set number of rounds wins the fight. If you lose, the game ends, but you can continue with a continue option. On the other hand, if you emerge victorious, you progress to the next opponent and get to watch an ending animation specific to the chosen character.
In console versions, special moves are unlocked after each successful three-bout win, but this feature is not present in computer versions.
