Your country has been invaded by rebel forces who want to overthrow the government. The rebels have won many battles and your country's defenses continue to crumble. Now you are your country's last hope. The enemies will come at you with tanks, attack helicopters, cruisers, fighter planes, and mobile fortresses. Destroy every enemy by taking control of the powerful helicopter known as Thunder Blade. You're equipped with a rapid-fire 30mm automatic gun and unlimited Straight Line air-to-ground missiles. Four stages that include a total of 12 rounds will have you flying through cities as well as over deserts and oceans. Some levels provide an overhead view while others provide a third-person view from behind the helicopter.
