ZX-Galaxians is a version of the famous arcade game. You are being attacked in deep space by formations of hostile Galaxians and it is your mission to prevent them from attacking Earth. You are provided with three spacecraft armed with powerful laser-bolts with which you must fight the Galaxians, BUT be warned, the Galaxians will swoop from the formation showering bombs as they go.
This is an unlicenced clone of the arcade classic Galaxian. Although the outside cover of some versions states "For The 16K ZX81", the inlay states that it only requires 4K of memory.
