Guardian II: Revenge of the Mutants

The mutants are back and this time they're faster. In your Mk.II Fighter you have to stop the Raiders flying across the planet and picking up Earthlings and turning them to Mutants when they reach the top of the screen. When all Earthlings are gone then it's game over.

If you shoot a Raider holding an Earthling then it will drop him. You have to catch the Earthling and place him back on the surface. Other aliens to worry about are Hive, Dynamo, Technofighter, Firebomber and Lure.
