It's not really based on anything more than the fallout wiki. It's just a boilerplate "vague sci-fi flavoured plot" slapped onto Popular Franchise - actually it's kinda like Star Wars 7 (can't remember the name, don't care).

They've heard of this thing called "lore", and know it gets the line to go up, so they got a guy to add in the maximal lore references and another guy to taze the first one when they start to talk about consistency.

Amazing prop work though, and I liked the actors.
