I saw a video in which some characters of the Fallout tv show open a fridge and find an alien and just toss it out because they want the working fridge. I’ve never understood (or really bothered with) why Fallout had the nuclear “event” which triggered the use of the shelters. Was it an alien invasion?
Tbh that could be from pre-Bethesda lore. As far as I know the old “Fallout Bible” book is no longer fully canon, but some things still are.
