This game manages to annoy before you've even grabbed your joystick. The futuristic insert belies a screen that's really bare and boring, and the sci-fi story on the cover does nothing to tell you why you're zapping.

Oh well, better make an effort. Apparently, you're one of a small number of men surviving on a planet completely overrun by robots. Or maybe you're a robot? Anyway, there are mines, and things that could pass for robots to zap. That puts up your score. Then there's the little men walking across the screen. Do you zap them too, or are they robots that look like men? Trouble is, I can't be bothered to find out.
