The gameplay remains identical to its predecessor, but it once again revamps the EX Mode system, removing the Drive System in favor of EX Bursts. It also adds a third EX Mode option called Extend along side the original Shooting and Fighting modes. The ON in the title represents the newly added online functionality which allows players to play together or against each other.
Alongside the arcade mode, called Branch Battle, the Playstation 4 version will include Free Battle along with local multiplayer splitscreen play. Returning from the Extreme Vs. series is a mission mode called Maxi Boost Mission where players can take on various battles with unique stipulations and challenges. Completing these missions will also award GP which can be used to upgrade units.
