Fallout London Proton Installer

An unofficial installer for Fallout London for the Steam/Proton version of Fallout 4.

Prerequisites

• p7zip
• protontricks
• jq
• steamcmd
• Steam for Linux with Fallout 4 installed
• Fallout London installed via GOG/Heroic Games Launcher

Instructions

1. Ensure all prerequisites are met.
2. Run Fallout 4 at least once to ensure the game has created the expected files and directories (and Proton prefix)
3. Clone this repo with git clone --recurse-submodules https://github.com/afwolfe/fallout-london-linux-installer.git
   • The --recurse-submodules argument is important to clone the downgrader.
4. Run ./install-folon.sh and answer all prompts.
5. Verify that the script completes successfully.
6. Install the FalloutLondon-$BUILD_ID.7z file using your preferred mod manager.
   • rockerbacon/modorganizer2-linux-installer - provides an automated way to install MO2 for Proton games
   • If using MO2 - ensure that you either disable profile-specific INIS or copy the recommended configurations into the profile
7. Launch the game via f4se_loader.exe

Advanced Usage

You can run the downgrade unattended by setting all of the required CLI arguments and logging into steamcmd ahead of time. The following arguments the script will attempt to autodetect if they are not specified:

• Fallout 4 installation (--f4-app-path)
• Fallout 4 Proton prefix (--f4-prefix)
• Fallout London path (--folon-path)

The other arguments must be provided or else the downgrader will prompt you for them when it gets to that part of the script.

$ ./install-folon.sh --help
Usage: ./install-folon.sh [OPTIONS]
