Beyond the Doors is an atmospheric, immersive horror game set in the surreal setting of a dilapidated apartment building. The protagonist, a reclusive technician, has set up operations in a cramped basement, from where he maintains total surveillance of his neighbors. The oppressive architectural setting, with its gigantic abyss in place of a courtyard and a strange glass ceiling, creates a persistent feeling of isolation and paranoia. Nighttime forays to the upper floors to plant bugs or search for documents in the trash become a true test of the nervous system. Terrifying secrets lurk behind ordinary apartment doors, and reality around the protagonist gradually distorts, hinting at the presence of otherworldly forces.
