The gameplay revolves around mobile suits, which can be upgraded using UC points earned by completing missions. Players must manage ammo for their ranged weapons, as well as alternate fire modes, to maximize their effectiveness. Boosting and dashing can help avoid enemy attacks or create distance, but these actions deplete the player's fuel gauge. By weakening an enemy mobile suit, players can scavenge its armor and fuel for replenishment.
Completing missions rewards UC points that can be used to upgrade pilots, mobile suits, and weapons in Unicorn Mode. These upgrades also grant access to new mobile suits and generic pilots from the Laboratory, which can be used to build squads for Custom Cast Mode. This mode features timed combat arenas where players must score kills to clear stages, with the option to rename generic pilots.
