The fighting system works around a four attack button configuration, consisting of punch, kick, slash, and heavy slash. Additional buttons allow the player to perform taunts, and throw enemies in the air. When a character causes damage or moves toward its adversary, a tension gauge charges. However, when a character moves backwards or uses defensive moves often, its tension gauge is reduced. Once a character's gauge is filled super moves called Overdrive Attacks, or a variety of special techniques—"Instant Kill", "Faultless Defense," "Dead Angle Attacks" or "Roman Cancels"—can be performed.
