These games run on tension more than gore. You walk through empty rooms, check every corner and try to figure out where the danger is coming from before it reaches you. Most ask for patience and good ears: stop when something moves, remember the way back, and don't run blind into a hallway you haven't seen yet.
Start with Backrooms: Exit Protocol 0 if you like hunting for a way out of yellow rooms while something follows you. Backrooms Craft mixes that same maze with blocky building, so you can shape the place a little instead of only running. Sprunki in Backrooms takes the singing characters and drops them into that same gloomy setting, which is strange in a good way. If you prefer company, Imposter 3D online horror puts you in a group where one of you is not what they seem.
