We're currently in the process of testing Linux support for Steampunk Graveyard and have set up Steam Beta builds.
To opt in, players will need to right-click the game in the Library, select Properties, go to the Betas tab and select the appropriate beta version.
If anyone encounters any problems, please let us know in the Forums or email [email protected]
We hope to make Linux support official very soon.
This is all possible thanks to our friends at https://linuxgameconsortium.com/
