Fallout London Steam Deck Installer

About the Script

This automates as many steps as possible to set up Fallout London on your Steam Deck.

The only prerequisite is installing Fallout 4 GOTY in English on your internal SSD.

This script performs the following actions:

• Downgrades the Steam version of Fallout 4 to the right version (pre-NextGen).
• Installs GOG through Heroic Launcher.
• Automatically moves the necessary files to the correct paths.

Note: Right now, this script applies the optimized .ini by @krupar101.

While this tool asks for your Steam credentials, it does not keep them locally, nor does it send them to any third party outside of Valve. Instead, it uses SteamCMD, a command-line version of Steam provided by Valve.
