Did you know that there was a horror side-quest in the open-world RPG sensation that is Fallout 4? No, neither did I. You just know I hauled ass over to it as soon as I found out, though, low level be damned.
Fallout 4 is set in Boston, which is close to the town of Salem, well-known as the location of many an execution back in the times of suspected witches. It is also home to the Museum of Witchcraft, which Bethesda have kindly included in the game, and is where you'll need to go if you want to bring some fear into your Fallout 4. The side-quest is called "The Devil's Due," and whether you hear about it in Diamond City, or go in search of it in the North-East of the Commonwealth like I did, it will completely change the genre of the game for a moment.
When you get to the museum, which I did just as dusk was setting in (for atmospheric effect more than anything else), you’ll find a dismembered corpse. It belongs to Private Hart, and if you listen to a holotape on her body, you'll discover that the rest of her team ran inside the museum. Something was chasing them. Naturally, you’ll want to go inside via an entrance to the basement.
Once you're inside, you're in a horror game. It is dark, blood drips from the ceiling, and mannequins make you jump thanks to a well-timed shriek in the soundtrack. Oh, and there's some growling coming from upstairs, too. Damn you, Bethesda.
That’s all I’m going to tell you. The reason I loved this side-quest so much, even if I was nowhere near powerful enough to complete it, was the complete and utter surprise that it existed in the post-apocalyptic world of Fallout 4. Mutants and giant mosquitoes, sure, but horror? Surely not. If you love horror, and own this game, check it out. Hint: Take a big gun.
