Finally, the highly-anticipated Fallout London mod has been released, offering a complete overhaul of Fallout 4. The ambitious five-year project, developed by Team Folon, brings players into post-apocalyptic London. The process of installing Fallout London varies depending on whether you’re using Steam or GOG, but you’ll need the previous-gen version of Fallout 4. Also, installing the mod could potentially delete your existing Fallout 4 saves, if you’re not careful.

Downgrading Fallout 4 and installing the new mod can lead to irreversible changes that may impact save files and mod setups. This has sparked a lot of discussion on Reddit for those with extensive playthroughs and mod collections.

There are ways to keep your Fallout 4 save files

For GOG users, the process of installing Fallout London is relatively straightforward. A few months ago, when Bethesda announced the next-gen update of Fallout 4 was coming just weeks before the launch of the new mod, GOG stepped in to host the mod, a move that could be revolutionary for large-scale modding. Steam users have a bit more work to do, as they will already have the next-gen version of Fallout 4 downloaded by Steam. In short, the process involves manually downloading specific files and using the downgrader tool to revert to the previous-gen Fallout 4.

One of the concerns with the whole installation process is its impact on existing saved files. As you’ll need to replace your configuration files with those provided by Fallout London, this poses a risk of losing your saves and custom game settings. The ‘irreversible changes’, that have sparked a lot of debate on Reddit, seem to refer to the fact you won’t be able to play Fallout 4 if you place Fallout London files into your Fallout 4 folder.

To ensure you don’t lose any progress, make sure you back up and move your save and configuration files to another location before the installation. Once you’re finished with Fallout London, you can delete the new saves and place your backups in the saves folder. Using mod managers like Vortex or MO2 will help when it comes to sorting profiles for different sets of mods and configurations. Going forward, this means you’ll have an easier time when it comes to switching between Fallout London and your regular Fallout 4.
