Playing Warhammer: Vermintide 2 on Steamdeck

Due to this game using Easy Anti-Cheat (EAC) and EAC having limited support for Linux, the game does not work out-of-the-box on the Steamdeck. Here are the tweaks I had to do to get it to work. Before diving in, make sure to read the note at the very end of this post about preserving settings.

• Delete Vermintide 2 compatdata directory  (It's here: ~/.local/share/Steam/steamapps/compatdata/552500)
• Do 'Verify game files' using the Steam client
• Delete WebView2Loader.dll and MicrosoftEdgeWebview2Setup.exe. ( By default they are both here: ~/.local/share/Steam/steamapps/common/Warhammer Vermintide 2/launcher. But the location is slightly different if you have installed the game on an SD card. You can find the exact location using Browse local files option in the Steam client. See the screenshot below.)
• Then run the game!

Note: The user settings and game saves are at the following locations. Back them up before deleting the compactdata directory if you don't want to lose them.

• .../steamapps/compatdata/552500/pfx/drive_c/users/steamuser/AppData/Roaming/Fatshark/Vermintide\ 2/user_settings.config
• ../steamapps/compatdata/552500/pfx/drive_c/users/steamuser/AppData/Roaming/Fatshark/Vermintide\ 2/save_data.sav

You can find more details on the ProtonDB page of the game here.
