A 3D take on Asteroids that finds you defending an orbital space station from damage.
You will have to deal with the deadly 5th waves (wave 5, 10, 15, etc.). A mother ship approaches your space station and you have to enter through an access tunnel in the rear of the ship and destroy its reactor core ... very difficult. As you progress through levels you can update various systems on your ship (to improve your engines, lasers, etc.). Also, more and varied types of enemy ship begin to swarm in on your space station - attacking you, pulling off segments of your space station, etc.
