Asteroid Force is a simple arcade style game. You are the pilot of a space ship with one mission, protect the Earth. As the levels progress, more and more asteroids show up. Asteroids vary in size and speed. There are also power-ups in each level that allow you to upgrade weapons, heal the Earth, add extra time, and earn extra lives.
