Mobile Suit Gundam Extreme VS Maxi Boost ON is an update to the arcade game Mobile Suit Gundam: Extreme Vs. Maxi Boost, released in March 9, 2016 and July 30, 2020 worldwide for the Playstation 4. Its theme song is No Future by SiM. It would finally be succeeded by a proper sequel in 2018: Mobile Suit Gundam Extreme Vs. 2.
The gameplay remains identical to its predecessor, but it once again revamps the EX Mode system, merging it with the Overdrive. It also adds a third EX Mode option called Extend along side the original Shooting and Fighting modes. While it offers no stat bonuses, it allows the user to escape combos without the gauge needing to be full. 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 also includes 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. Unlike the previous games' mission modes, mobile suits are not leveled up individually. Instead the player does. Leveling up increases Upgrade Slots, which allows for an increased number of bonuses and these are automatically assigned to any currently selected unit. Missions are grouped into Areas, each more progressively difficult. At the end of each Area is a powerful Boss. By completing Break Missions, the boss can be weakened to make the challenge easier.
