APT. 407 is a first-person psychological horror game that immerses you in the atmosphere of an abandoned house with a disturbing past. There are no monsters here — only sound, silence, and anticipation, which is always a little closer than you'd like. Whispers under the ceiling Explore an old Korean high-rise, where empty corridors and strange noises lead to a story long lost to time. Knocking from above, clicking sounds in the walls, a chill from the empty apartment above — the details add up to a disturbing picture. Read discovered notes, open locked rooms, and explore interior details. No loud jump scares, no action — just bone-chilling anxiety. The audio and visuals faithfully replicate the atmosphere of real old-style apartments. Game features Atmospheric development: each room is modeled on real prototypes. No interface - just you and the space. Two different endings, each revealing a new plot point. The effect of presence due to minimalistic sound and light.
