The player must shoot towards the enemies, and if the player is hit, they lose a helicopter. The player has limited fuel and ammo, and must land at their base to refuel. The player has 3 helicopters, and it's game over when all are lost. There's 4 levels of difficulty, and the player can chose 8 levels of helicopter speed.
