Plays somewhat like the Assault Suit series. Fun gameplay, can switch out your three weapons and melee attack, voice acting for all the dialogue (though it is in Japanese). Very short. The five stages offer variety but two of them have you in very small areas. Scoring system to unlock new weapons is terrible, requiring scores that forces you to grind, by the end of the games five missions you might have reached 3,000,000 points for the first unlock, with the next needed twice as much and the last needing 99,000,000. Annoying zero gravity gameplay that is only used for final two bosses, giving you no time to get used to it unless you do the training mode and giving you no time to use it against regular enemies to change up the gameplay.
