It’s definitely an awkward lead-in, but the game is content to give you next to no power as the new Overboss. Kill him and suddenly you’re the new Overboss, despite the fact that the Raiders didn’t even know you existed 10 minutes ago.
One of the chief complaints about Nuka-World will no doubt be the rather hurried set-up to the concept, where you, a wanderer, are tricked into visiting Nuka-World on a presumed quest, only to fall into a trap the Raiders call “The Gauntlet,” which has you running through a booby-trapped maze and fighting the Overboss of the entire encampment at the end.
