First release of EngiQuake, includes one proper map + start map. Installation like any other Quake mod. Due to an error you should use either FTEQW or Quakespasm-Spiked.
You need to extract the zip to your Quake folder, so that you have .../Quake/engiquake/pak0.pak etc, then you can run the mod with launch paramaters -game engiquake. Due to an error in the code, the mod can crash with some engines, the engines I developed and tested with are Quakespasm-Spiked (regular QS crashed) and FTEQW.
