Archrebel
"A strategy game heavily inspired by Julian Gollop's Rebelstar, released back in 1986 for the ZX Spectrum and Amstrad CPC remaining as my favorite title on the ZX Spectrum computer. Unfortunately, due to the hardware limitations of the ZX Spectrum, Rebelstar suffered from severe constraints and nowadays standard features, including the lack of a map and line of sight, no menu options, and had only one playable map.
Archrebel is my attempt to capture Rebelstar's essence, sharing the same sci-fi setting while expanding its formula through a large campaign offering more content.", developed by Ularis Badler
