Using alien technologies, a military force has swept to power on Mars. This totalitarian regime must be stopped and its robodroid armies destroyed. You are an elite pilot in charge of a VacFighter, an experimental craft equipped with both air-to-air and air-to-ground weapons.
To successfully complete your mission you will need to master your fighter and its weapons. New weapons, bonuses and surprises will be available as you progress across the Martian battlefields!
This is a basic, top-down shooter that came pre-installed on many Macintosh systems. There is litter in the way of story once the game begins - it is all arcade action. It is also the sequel to "Mars Rising".
