I found a demo for a game called Fazbear Eternal. The game takes Doom's 3D-looking, retro level design and combines it with FNAF's dark and atmospheric aesthetic. I recommend trying this demo.

Silent Trench is a singleplayer horror game set in a dark facility deep in an oceanic trench. Pinging with your visor for snapshots is the only way to see, but it may also get you seen.

Demo available now, free on Steam: https://store.steampowered.com/app/5333270/Silent_Trench/
