It runs with wine and proton and theres startup scripts to help along with this included with the game
i recommend using the gamescope version if you have gamescope since it preserves the appearance of what the game looks like on windows also it runs better
currently gamescope is broken on version 3.16.19-1 downgrade it to 3.16.17-1 to make it work right
All of these scripts are tested against arch based distros but we do ask people on other distros to report if they work for the game or not so far theres no issues other than gamescope doesn't work for LTS distros like ubuntu/mint
