I beat the campaign once and that was enough for me. You need to fly around to collect ammo (little blue dots on the screen) while dodging and killing enemies to get to your real goal, the asteroids. Destroy all asteroids in a level and move on to the next. There are powerups as well, which help, but you will mainly be flying around collecting ammo and blasting away at asteroids.

I enjoyed the one play through i did, it was a fun two hours, but i would NOT pay more than $1 for this. The campaign is short and It's too repetitive for the high-score game modes to be fun.
