Protector

The planet Zargon is under attack from an alien invasion and you have been tasked to fly your craft and blast as many aliens as you can to beat their score from their bombing raids. The game is a horizontal side view shooter with the screen scrolling from left to right constantly. As you fly over the surface of the planet you will encounter various alien crafts and all must be destroyed with your limited amount of lasers but you can get more by landing on landing pads. If you are hit by an alien craft or it's weapons then you lose one of five shields and when they reach zero you lose one of five lives. Being hit by bombers or hitting the surface loses all the shields in one go and loses you one life. There are six levels to choose from (1-6) with six being the hardest.
