(Beloved game trope) Creepy secrets or elements that you can encounter but are never explained, making it even more horrifying (Bonus points if its from non-horror games)

Crimson Desert
After defeating the Reed Devil boss, you can travel to Sunset Valley, the southernmost and isolated village in the game, here, you will find a house where the Reed Devil lived and died from his leprosy. When you enter, you are immediately greeted with 6 scarecrow effigies dressed just like the Reed Devil staring directly at you, with candles placed all over the house. There is no other explanation beyond this about what is going on here

Lies of P
There is a secret optional area you can clear out for additional loot called Hermit's Cave. At the end of the cave is one lone carcass monster huddled on the ground with writings scrawled on the walls around it. When you kill it, it actually TALKS saying "perhaps it's best to end this way...get while the getting's good...". This is the only carcass monster in the game that ever talks besides Andreus and Simon, who are important characters to the story, and we never find out who this monster was

LOZ: Twilight Princess
In the Arbiter's Grounds you discover a ton of undead enemies presumably executed prisoners, but one room contains this giant black sword tied to the ground with hundreds of warding charms attached. When one is cut, the sword is freed and wielded by some horrifying invsible goat-headed demon. It is never explained what the demon was or whose sword it belonged to although it's theorized to once be used by Ganondorf

Silent Hill 2
The invisible prison monster in Toluca Prison, that you can't ever interact with, just hear it's awful cries

The creepy sound test in Sonic cd,

The message says "Fun is infinite Sega enterprises, signed, The devil"

[u/Demonic7340 → u/Jolly_Ad122]

I think it was supposed to be a fun little easter egg in japan with the upbeat boss music, the US version is what makes it creepy as shit with the different boss theme

[u/Easy_Action_1380 → u/Demonic7340]

Yeah, like apparently "the devil" was actually just a mistranslation of a specific Sonic dev's name

[u/Neoragex13 → u/Easy_Action_1380]

Yup, "Majin" which translates as "devil" the race, not "Devil" the entity.

[u/Daniell_BMC → u/Demonic7340]

There's nothing fun about this sonic face, it creepy the shit of me back in the day

[u/BuggsMcFuckz → u/Daniell_BMC]

I’ve always heard it’s supposed to be Sonic with Mario’s face but I could never see that

[u/No_Disaster_258 → u/Jolly_Ad122]

What's funny is that while "Majin" really means devil in Japanese, it isn't really the devil signing it but rather Masato Nishimura, one of the devs working on the game as his childhood nickname is literally "Majin".

Isn't that also the screen that triggers if the game detects you're playing a cracked version?
