This game takes place in a country that is in the grip of a civil war. You are in command of a heavy Fortress which is under attack by another fort captured by rebels. To destroy the fort you have to hit it 4 times with your main gun, but the wind will blow your shells off target. While you can adjust your firing force to allow for the wind, the wind speed or direction can alter while the shell is in the air (there is a reading of the current wind speed and direction at the bottom of the screen). Unfortunately, the wind has carried several shells over the border into a powerful neutral country and they have sent their air force to bomb both forts. The planes have lasers that can explode your heavy shells in the air, but not your anti-aircraft shells. If you shoot down a plane, it allows a supply truck to reach you with some repair materials.
