Total Chaos Legacy - Flatpak Build

Retro Edition v1.40 on GZDoom Legacy v3.8.2

This project contains files to build Total Chaos - Retro Edition as a Flatpak app.

Retro Edition has reduced texture resolution and poly-counts for improved performance. Save files from other versions of Total Chaos are not compatible.

The game runs using the GZDoom Legacy v3.8.2 engine to ensure more compatibility with old computers. It requires OpenGL 2.1 or later and at least 1GB of free RAM.

This project is based on com.moddb.TotalChaos.
