nanoUFOIf you want to play that whopping Fallout London mod you'll need to downgrade Fallout 4's "next gen" version
EdanGreyI play on steam, or on console, I guess I won’t be playing this mod!
SturgiesYrFaseIt says in the article that it comes with a downgrader packaged in the installer. That said they’re working with GoG, so the downgrader might not work for the steam edition.
Downgrading should be possible on steam via steam console commands. I noticed large collections on Nexus usually tell you to use some sort of downgrader program but I’ve always just used the steam console instead and been fine.
