|A vertical shoot-em-up that places the player's helicopter against multiple attacking targets in the air, sea, and land. Collecting the weapon and speed power-ups throughout the game is vital since the gameplay is quite difficult.|
The object of the game, which is not explained, is to avenge your brother (which means that you are Joe!). To do so, you must destroy the fortress on the very last level. When you start the game and it scrolls onto the starting screen, the background contains the different levels that you must survive. The starting position of the various enemies does not vary from game to game.
