After years of development and a last-minute, Bethesda-induced delay,Fallout 4megamod Fallout: London is finally here. A “DLC-sized” undertaking, Fallout: London takes the series' post-nuclear apocalyptic setting and transports it all the way across the Atlantic to dear old Blighty. It’s even enlisted aformer speaker of the House of Commonsand Baldur’s Gate 3’s Astarion—voice actor Neil Newbon—onto its voice acting crew. You canadd it to your GOG libraryright now, completely for free.
It’s also a bit of a bear to install, depending on where you own it. You can thank Bethesda for that: When Todd Howard and co released FO4’s next-gen patch, it thoroughly borked Fallout: London’s compatibility. That means you need apre-next-gen version of Fallout 4, and all of its DLCs, for the mod to work. If you own them on GOG? That’s easy as eel pie. If, like me, you have FO4 on Steam, it all gets a bit more complicated.
How to install Fallout: London on Steam
We’ll start with the harder (and more popular) option. Those of us who own FO4 on Steam have no easy way to access the game’s pre-next-gen version, which means you’ll have to make use of the Fallout: London Team’s Downgrader Tool to roll the game back.

How to install Fallout: London on GOG
You should do it this way if you have any choice in the matter. Heck,FO4 is even on sale on GOGfrom now until August 2, 2024, if you want to fork over some money to save yourself the headache of a Steam install. Anyway, here’s a (much shorter) guide to install Fallout: London on GOG, which isn’t too different to the guide on the mod’s GOG page (it really is much simpler).
And then you’re off to the races. Like I said, you’re really better off doing this the GOG way if you can, but either way you’re in store for a meaty and thoroughly British Fallout experience. Do note that you won’t be able to play base FO4 with the mod installed. If you ever want to return to Fallout 4’s Commonwealth, you’ll need to uninstall both Fallout: London and FO4, then reinstall FO4.
