Space Gnats is an interesting combination of alien shooter game and interactive screen saver. In Space Gnats, the further you progress in the game, the more scenes the screen saver will play. Blast your way through 6 levels of alien mayhem or kick back and watch some amazing 3D graphics while listening to your favorite music. Shoot all Gnat fighters on each level before you run out of time, or it's back to the start of the level again. Blow up all the Gnats, and you'll move on to the next level. Make it through all 6 levels (3 on land, 3 in space) and you'll find a time tunnel leading you back to your own dimension.
