"You are a pilot. A time fighter, fighting a battle against aliens that are attacking the world in the air, on land and in the seas. A Time-portal, secretly invented by the great Leonardo da Vinci, will send you into the future to help fight the battle in 5 different time periods. Beware of the weather. For it can be rough in the Snow and Lightning Rain. Tornados can blow your plane out of control forcing you to go the direction of the wind. The greatest battle of our planet begins. Make sure that you are up for the challenge!! Mouse to move, left mouse to shoot, space to drop bombs and end to pause."
