Minecraft.
You're stuck in a world, alone or maybe not. There's the undead, the angry wildlife and the THINGS coming from all directions. There's a corruption god you can summon to fight that kills you in a horrifying way. You can enter Hell, talking to rotten pigman undead and playing WIPEOUT tennis with giant screech-voiced jellyfish things, oh and skeletal minions of said corruption god. You can even go to the edge of existence and fight a big dragon-like god to be granted a way out of this ungodly zombie stew.
Seriously the game is full of fridge horror so much it's not funny. Think about it.
