This game has an essential difference - instead of firing ahead, you lay gas clouds behind you to destroy the aliens. The aliens are made of anti-matter, so as they rush headlong into your vapour clouds they're anihilated. You must score 1000 points within 40 seconds to get to the next level, an idea which makes this game extremely addictive to play. Wrap around screen, 8-directional movement in a very crowded screen. Hiding inside one of your vapour clouds is a sneaky way of avoiding death. Joystick: Kempston, AGF, Protek, Fuller or Mikrogen II. Good value.
