If the game you wish to install is not available natively as a Linux/Steam Play game, you may be able to run it using Steam's built-in Windows game support.
Lutris is a central game manager which allows you to install games from multiple platforms easily: Windows games, GOG, retro emulators, the web, Linux games and more.
We would recommend installing Windows games using Steam with Steam Play/Proton enabled or Lutris (see above) for improved support.
If this is not possible for your desired game, please follow our instructions on how to install Windows apps & games.
