The four of them seemed to be having a conversation, but one of them wasn't wearing clothes (other than underwear) and he had his hands up in the air. Another was wearing what seemed to be a white BDSM outfit that barely covered his privates. Naturally I shot him first, but I really want to know what the hell was going on. At first I assumed the guy with his hands up was a captive, but it turned out he was just a nearly naked raider... I'm so confused.
Throughout the game there are certain locations where you trigger random encounters upon entering from a certain angle.
This was one of those random encounters.
If you had waited a bit, the raiders would have started beating the unarmed dude with baseball bats and stuff.
Common theory is that this is supposed to be some kind of raider initiation ritual.
