There is definatly a reason why this game is famous, at least in the retro gamers circuit. Nope, it's not for it's awesome gameplay or even colorful anime type intro, but rather for the worst translation ever known in video game history. The game itself is actually kinda fun, not the best shoot'em'up I ever played but definatly not the worst either. You have 4 different types of ammo to use throughout the stages each of which can be powered up, sadly none of the power ups really look all that cool when your shootin, but its still fun none the less and a little challenging, but because there isn't much else to this shooter to set it apart from others of it's era gameplay starts to feel bland by stage 3. Graphically the gameplay is not as cool as the intro, M.U.S.H.A. has much better graphics or even Grindstormer but still, just the intro alone is reason enough to have this in your collection. Watch this video to see the worst(and most hilarious)game translation ever, at least imo.
