I have been a long time Linux user, and playing Windows Games on here can be difficult at times. It has been getting better with time. Wine and Proton having been making strides. I believe with the release of the Steamdeck things will continue to improve for us.
Unfortunately, Gods Unchained is not on Steam. So, we will have to do some additional work to get it running on Linux.
My past guides on this subject have been nitty-gritty do it yourself adventures. The good news is this is no longer the case. Let me introduce Lutris it is a powerful game launcher that allows to hook into your existing collections on Steam, Humble Bundle, GOG, and others.
First we need to install Lutris. Please be aware you will need root access to install this program with these instructions.
