About 5 Nights at Mar-a-Slopo

Explore fifteen connected rooms in a dark estate with a flashlight and a map. Follow five nights of disturbing discoveries, find places to hide and escape its inhabitants. This is an early horror alpha with sudden scares, pursuit and original creatures.

18+ 18+ horror: disturbing creature imagery, pursuit and sudden scares. A fictional estate, not an affiliated product or a depiction of actual events.

Alpha 0.4. 5 Nights at Mar-a-Slopo is still being built. Expect rough edges, and expect them to move.

Latest update: Alpha 0.4, The doors open themselves

  • Real hinged doors in every passage. They swing open ahead of you, shut behind you, and a closed door hides you from the hunter.
  • The house plays tricks that change each night: doors that open on their own, a slam in the far wing, and the light dying for a few seconds.
  • Each room is haunted differently on alternating nights. The phone map now shows all 15 rooms.
