I love Amnesia: The Bunker to bits. It's a stressful as hell, suspenseful, and downright terrifying game that mashes up immersive sim experimentation with classic survival horror resource management. One of my favorite parts of the game, though, didn't directly involve the monstrous creature that pursues you throughout the story. Spoilers for The Bunker from here on out.
It's pretty early on in The Bunker when you first start hearing scuttlebut about the haunted Roman catacombs underneath the titular French military installation. I didn't even need to find the later journal entries by a guy hearing whispers from unspeakable terrors down in the depths to conclude "Ah crap, I gotta go down there eventually, don't I."
