Fallout London, the long-awaited total conversion mod for Fallout 4 that might as well be an entirely new game, is finally here. Installing it requires quite a few steps, though, so here’s everything you need to do to download, install, and play the Fallout London mod.

As it stands now, players can only install and play Fallout: London if they own a copy of Fallout 4 on GOG or Steam. Epic Games owners will have to wait a little longer, as the platform does not support rollbacks. Fallout: London is not playable on the next-gen version of Fallout 4 and therefore will not work on the Epic Games launcher. Hopefully, the mod's creators can adapt the mod to the latest version of Bethesda's post-apocalyptic RPG so that everyone can enjoy it to the fullest.

Please note: You will need all DLCs for Fallout 4 to play the mod, regardless of platform.

The creators of Fallout: London have partnered with CD Projekt's GOG.com storefront to distribute the mod. Players who own Fallout 4 on the platform can simply navigate to Fallout: London via the GOG Galaxy launcher, and it will seamlessly download and install after downloading Fallout 4 itself. Those who own the game on Steam will need to take a few additional steps to ensure the mod runs smoothly on their copy.
