In this game, you are an American fighter pilot. Your mission is to shoot down enemy planes, shoot at enemy ammo dumps (which look like little black houses) and enemy anti-aircraft guns (which look like sundials). If you stay in the air too long, you will receive a warning for flying too low. If you don't correct it, you will crash. You can also be shot down by anti-aircraft guns or enemy planes. Press left or right to go in that direction, up to go down and down to go up. Press the fire button to fire the machine gun.
In this game, you have entered subway caves on another planet. You proceed to destroy the enemy spaceships and force fields. You move the target reticle by moving the joystick, and fire your weapon by pressing the red button. You will see the spaceships coming from far away, but if you get too close they will bombard you and you will lose energy. When you see the force field, you will see a square on the right side. Shoot that square and the field will deactivate. If your ship collides with the field, you will lose energy. Destroying your ship or disabling the force field will increase your energy. Use the map at the top of the screen to determine which direction to take. If you choose the wrong path or run out of energy, the game is over.
