You stay on the guard of Galaxy trade ways. Your task is to destroy all dangerous asteroids on your way. You have missiles of different colors. Use them for asteroids of the same color. If you shoot the asteroid with the missile of another color it simply changes its trajectory and your missile becomes a new dangerous asteroid. Asteroids can attract some space garbage and grow in size. When asteroid becomes too big or you shoot the big asteroid it is crushed into two fragments that become new asteroids. Do not allow asteroids to approach your space ship and crush it. Lets go to clean Galaxy ways now!!! Want more fight? Try now!
