Zynaps is a smart side-scrolling shoot ’em up, developed by Dominic Robinson, John Cumming and Stephen Crow (with music by Steve Turner), and published by Hewson Consultants for the ZX Spectrum in 1987.

The graphics are colourful and smooth-moving, and the gameplay is quite tough.

Zynaps is definitely one of the better shooters on the humble Speccy and is still played and enjoyed by games-players today.
