This mod also works on Linux!
Instead of using the .exe file:
1) Copy the included "BepinEx" directory to the Game's main directory
2) Copy (+ overwrite) the two dlls in the "Copy to game" directory to the game's main directory as well.
And use the following launch options in Steam:
WINEDLLOVERRIDES="winhttp=n,b" %command%
Make sure your SteamVR application is started before launching the game!
If you get a command-prompt window when you start the game it should have initialized correctly.
