History

Cosmic Swarm is a simple little 16K game that I wrote in 1983 alongside Megapede, Robon and Repulsar. The game was submitted for publication, but as far as I know never released and has been considered MIA, though it did appear in a few magazine ads at the time.

Like many of those earlier games it features single screen, character-based movement and was written in compiled BASIC for the 16K Spectrum. Since I have now have the source, I've recompiled it with Colt for the 48K model and added multiple key input rather than the limited single key, INKEY$-based input of the original. Gameplay remains unchanged.

I don't think it ever had a proper loading screen - at least not on the C15 tape I discovered from 1983 - so I knocked one up in ZX-Paintbrush for the occasion.
