In true Fallout tradition, Fallout 4 is filled with moral dilemmas and weighty choices, with one of the game's most infamous coming in the form of the Devil's Due quest. Hopefully you're not afraid of Deathclaws.
Fallout 4 The Devil's Due Quest Guide Delivering and Returning the Egg and Deathclaw Friend
The Devil's Due will pit you against some of the Commonwealth's most formidable foes, namely the Deathclaws that have been terrorizing the Wasteland's inhabitants since the very first Fallout game. You'll want to make sure you're leveled up and well-equipped before embarking on this quest, but the rewards can be proportionately large… if you choose the right path, that is.
You can start this quest by heading to the town of Salem (not to be confused with the online game) in the Southern Commonwealth, but I highly recommend hanging around Diamond City first to get the intended start. Talk to one of Diamond City’s talkative guards enough and he’ll eventually mention that something strange is going on in the Museum of Witchcraft, which will place an objective marker at the specific location you need to visit and save you the trouble of combing through the city.
The journey to Salem can be a tough one. Just keep heading towards your objective marker, hopefully avoiding all the creatures that want to sever your head from your shoulders along the way – you'll have more than enough of them. The objective marker will lead you to the body of a soldier named Hart, a Gunner mercenary who has apparently been tasked with a special delivery. The story gets more complicated.
