Where better to start than with a shoot-'em-up? Atari owners may not be able to experience the joys of Uridium, but they can come close with this vertically scrolling blaster.

The plot is as simple as you could wish - zoom across the asteroid surfaces, wrecking any structures that get in your way and taking pot-shots at the swooping alien craft, which don't take too kindly to your wanton vandalism.

The asteroid graphics are great but the aliens look rather washed out. Still, they swoop around fast enough to keep you on your toes.
