To the Earth

You are on a mission to save the Earth. You are the commander of a highspeed astro cruiser. Meteors are crashing. UFO's hurtle towards you at astro speed. Deadly alien vessels take a collision course. Use your Zapper® Light Gun to blast back. Your weapons snap and flash as wave after wave of extraterrestrials attack! Saturn and Jupiter may hide more treacherous aliens. Zoom past them, but don't relax your guard - not until you've fought your way - The The Earth!
