It is possible to run GoldenEye: Source under Steam for Linux via Proton. This is generally a better experience than installing Wine and a separate copy of Steam to play your Windows games. GE:S will appear as part of your Steam for Linux library. Performance may be lacking compared to Windows, but the game will otherwise function normally.

Before you begin, see the Proton requirements on GitHub.

Like the Windows install, there are two main components to install: Source SDK Base 2007 and GoldenEye: Source.

Source SDK Base 2007:

• In the main Steam window, go to Library → Tools.
• Find Source SDK Base 2007, right-click it and select Properties, and then check Force the use of a specific Steam Play compatibility tool. Select Proton 3.16-X Beta and close the Properties window.
• Double-click Source SDK Base 2007 to install it.

GoldenEye: Source:

• Download the server archive. The server and client installs are the same, and only differ in the format (executable installer vs. zip)
• Extract the gesource folder from the archive to your steamapps/sourcemods folder, just as you would for Windows.

With that done, restart Steam and you should see GoldenEye: Source pop up in your games library. Double-click it and it should run normally.

1. Due to bugs in Proton, it is currently not possible to play online. You can play offline with bots by opening the developer console and typing sv_lan 1. Alternatively, check “Run on LAN” in the Create Server dialog. Although untested, you may be able to play online if the server was started with the -insecure option.
2. This may have reduced performance compared to running GE:S via Windows. Nonetheless, with a powerful enough machine, GE:S should be very playable through Proton.
3. You may crash more frequently than on Windows. If this is the case, try lowering the texture quality to improve stability.
