Hello there.
I had made a small bash script for myself some time ago for installation/patching/verifying files, thought I should share it, even though I haven’t played in a long time. It is kinda slow and barebones but it does the job, maybe someone will find it useful while there is no official launcher for linux.

You will need to install the following packages for script to work:
jq xdelta3
Please read the script before executing it!
Run.sh launches the game using Proton experimental. You will need to install it via Steam.
You might also need to download https://lutris.net/files/tools/dll/d3dcompiler_47.dll to compile shaders on first launch. Put it in Renegade X/Binaries/Win64 folder.
