User Summary Cyber Rats was an early shoot em up game for the ZX Spectrum, in which the player controls a gun that moves across the bottom of the screen and tries to shoot down foes as they approach from the top. Unlike similar games such as Centipede, where the foe starts as a single chain which is shot apart by the player, in Cyber Rats the enemies start out as separate entities which move down the screen rapidly by bouncing off obstacles on the screen.
