Since the game is based off of a fighting game's game style the story and level progression are very straightforward. Battle one enemy after another in the single player, or battle your friends with multiplayer or over Xbox Live. Players choose from one of the 8 available characters, each one with their own specific moves and abilities. Attacks are performed using either the main weapon, the sub weapon, the barrage weapon, or special moves that are accomplished by performing specific button motions similar to a fighting game. Successful attacks increase a special gauge that when it's full allows you to transform your robot into a giant B.O.S.S. robot similar to a boss in a traditional shmup game that lets you launch super attacks.
To ensure the game is more than simply launching attacks against one another, various defensive maneuvers are available including a dash for quicker movement around the arena. Special combo and close up attacks are also available when you're in the proper distance from the enemy.
