One main feature of the combat system is the "EX Gauge", which can be filled in a variety of ways, such as inflicting damage on opponents, taking damage from opponents, and obtaining EX cores scattered around the field of play. Once the EX Gauge is filled, the character can enter their "EX Mode", significantly increasing their power and enabling new attacks, including the "EX Burst", an unavoidable and very damaging special attack similar to the Limit Break mechanic seen in many games in the series. The player on the offense charges up the attack by following the on-screen instructions, while the player on the defense can reduce the amount of damage taken by continuously pressing the circle button.
