Heavy is the head which wears the Overboss helmet. The game then encourages the Sole Survivor to go along with this, help the Raiders reclaim Nuka World then proceed to start settling the Commonwealth with outposts.
The premise is the Sole Survivor is invited to a sick gladiatorial game under the guise of rescuing someone's family, only to kill the leader of the Nuka World bandits in single combat before being declared their new leader. However, it is that very need to work with the deplorable and blunt their efforts which makes an intriguing path for those who don't simply want to have their Sole Survivor crack and go Raider. Indeed, there are only a handful of quests which do not require working with complete scum. It's an absolutely beautiful spectacle and blows the main game out of the water but it's also something which has been controversial for the fact it favors an 'evil' playthrough. I've mentioned my absolute love for Nuka World before and that remains to be the case.
