Requirements for installing and playing Fallout London

Before proceeding with the installation of Fallout: London, it is important to understand the requirements for both downloading and playing the game.

It is essential to note that upon its release, Fallout: London will not be compatible with the versions of Fallout 4 available on the Epic Games Store. Therefore, it is necessary to possess either a Steam or GOG.com version of Fallout 4. Fortunately, the mod is being made available through GOG.com.

To play Fallout: London, it is imperative that you have a PC copy of Fallout 4, complete with all its downloadable content (DLC). This includes the expansions Automatron, Far Harbor, Nuka-World, and all workshop packs. If you do not currently own these, you may want to consider acquiring the Game of the Year edition of Fallout 4, as it contains all the necessary DLC.

Fallout: London will require 33.8 GB of space, however, it is advisable to have additional space available for a smooth installation process. We suggest reviewing the drive where you intend to install the mod and deleting any unnecessary programs.

It is essential to highlight that, as stated on the mod’s GOG store page, ‘Fallout: London will entirely take control of your Fallout 4 installation’ and ‘introduce irreversible modifications’. As a result, if you intend to play Fallout 4: GOTY Edition, you will have to remove and then reinstall this version of the game. Furthermore, you will need to turn off cloud saves.
