Cyber Rats

Cyber Rats is an arcade shooter released in 1981 for the Sinclair ZX Spectrum. Developed by Iain Hayward and published by Silversoft Ltd, it challenges players to survive an unending metallic-rat menace.

The gun moves across the bottom of the screen while rats advance from above. Grass scattered across the playfield deflects the rats downward when encountered. Destroy each wave to trigger the next, continuing for a high score until all lives are lost.
