The plot of this game is quite 'cheesy': you fight your own comrades in order to become the ultimate fighter, the 'DonPachi elite team!'.

An excellent vertically scrolling shoot'em up. The player assumes the role of a pilot who is sent by their squadron to fight their former allies until one side destroys the other, all of which is a part of a mission to strengthen the military power that controls each side. The player flies their selected fighter over 5 areas of various terrain, encountering a number of land, sea and air enemies. The player's ship has two modes of fire: by tapping the fire button, shots are fired; holding it down produces a concentrated vertical beam, but also reduces the ship's speed.

Notes :
The default high score table contains a hidden message: read vertically, the initials will read, TOAPLAN.FOREVER.
The US version is slightly different, it has the "Winners Don't Use Drugs" screen.
