Been reading Fallout Equestria: Project Horizons.
What the... See, this fic takes all the grimdark that's in FO:E and... doesn't add new elements. Instead, it just takes what's there and takes it to its logical conclusion.
I've just witnessed an interrogation by raider. Not somepony being interrogated by a raider. No, it was by the hero. The interrogation was made
using a raider. I said Littlepip was like the Hobo With A Shotgun. Security is like Marv from Sin City, except even more ruthless, once you piss her off. Our protagonist, ladies and gentlemen. And the worst part is, the circumstances warranted that.
The amazing thing about this fic is that it found a reasonable explanation for the raiders' absurd violence.

They weren't just evil drug addicts. They're infected by a biological disease that sponges their brains.
And the Enclave is trying to turn it into a bioweapon, if they haven't already.
