You have to destroy puny little creatures which wander around the screen trying to catch you. When they do you lose a life. For your protection you are given lasers but you can only use four on the screen at any one time, which means certain death when you have five or more creatures, otherwise known as Cyborgs, closing in on you.
The instructions have had more time spent on them than the game, and the loading describes the game accurately, simple!
A word of warning should you intend buying the game: disconnect your Datasette once the game has loaded, because the motors keep running.
The game can be played using one or two joysticks and not keys. This may be a good thing. The sound deserves credit, and is a good standard. You get the chance to join the Cuthbert Club.
