Installing Guild Wars 2 on Linux can be done using Steam's Proton compatibility layer or by adding the game as a non-Steam game. Here’s how to achieve this:

Option 1: Install Guild Wars 2 via Steam using Proton

1. Enable Steam Play for all titles:

Open Steam and go to Settings.

Navigate to Steam Play.

Enable the checkbox Enable Steam Play for all other titles and select the latest Proton version from the dropdown.

2. Download Guild Wars 2 setup:

Go to the official Guild Wars 2 website and download the Windows installer (Gw2Setup.exe).

3. Add Guild Wars 2 as a non-Steam game:

Open Steam.

Go to Games > Add a Non-Steam Game to My Library.

Click Browse and locate the Gw2Setup.exe file you downloaded.

Add it to your library.

4. Force compatibility with Proton:

Locate the added Gw2Setup.exe in your Steam library.

Right-click it and select Properties.

Under the Compatibility section, check Force the use of a specific Steam Play compatibility tool and select the latest Proton version.

5. Run the Guild Wars 2 installer:

Launch the added game from Steam. The installer will open.

Install the game in a desired directory.

6. Configure the game executable:

Once installed, replace the shortcut for Gw2Setup.exe with the actual game executable (e.g., Gw2-64.exe) by right-clicking the entry in Steam, going to Properties, and editing the Target field.

7. Play the game:

Launch the game through Steam. Proton will handle compatibility.
