Flat 9
About this game
Sent to investigate an abandoned apartment, you are tasked with documenting strange occurrences using the A.D.D. (Anomaly Detection Device)—a specialized tool capable of detecting and repairing irregularities.
At first, the apartment seems perfectly normal, but as you explore, reality starts to shift. Objects move on their own, shadows flicker unpredictably, and unnatural occurrences manifest around you.
Gameplay
You are trapped in a loop in which you must identify all anomalies in the apartment to progress to the next one. Missing even a single anomaly will send you back to the previous floor.
Your mission is to address every anomaly you encounter and find a way out of Flat 9.
Content Warning
This is a psychological horror game that may contain jump scares and intense moments. Player discretion is advised.
