so you’ve already got the .rar file, which is good, but you’ll need a way to extract the game files. i dont use arch, but theres probably a multitude of ways to extract the files.

Once thats done, you’ll need a way to run the executable. you can either: use windows (self explanatory) Use proton and steam: get steam, get proton up qt, get the latest proton GE version, add the .exe to steam as a game. then in the game page settings, go to properties and then compatibility. once there, choose a specific steam compatibility tool, and use whatever proton version you just downloaded. normally it should work, but linux is weird sometimes, and with a game this big, nothing is certain. you can also try lutris, but youll have to look for tutorial on yt or smth for that
