JUST HORROR

P.T. centers on a protagonist who awakens in a house from which he cannot escape,[nb 1] in which he can only walk through a continuously looping hallway. On one loop, the radio in the home reports on two cases of familicide, in which fathers committed the act; one was chanting a string of numbers. Later, the radio addresses the protagonist and utters the numbers "204863", the string of numbers that one killer was reportedly uttering. The radio issues other messages in various languages.The protagonist soon encounters Lisa, a hostile female ghost, and upon entering the bathroom, obtains a flashlight and finds a fetus in the sink. Later, after being attacked by Lisa, the protagonist reawakens in the room, beginning the loop again; in the room, a bloody, moving paper bag speaks to him, revealing that the "gap in the door" is a separate reality and warns him that "the only me is me. Are you sure the only you is you?" Eventually, the protagonist hears a woman being killed in the bathroom as the radio urges her attacker on. Upon entering the bathroom again, the fetus addresses the protagonist, revealing that ten months earlier, he had turned to alcohol after losing his job. His wife had then found part-time employment because a manager felt physically attracted to her.

After another loop, a voice eventually utters "204863" repeatedly, and the game screen acts as if it has crashed. The protagonist awakens in the beginning room. After the final puzzle is completed, a caller reveals that the protagonist has been chosen. In the subsequent cutscene, a voice laments that his father had lived a life of regularity until he killed the speaker and others without any creativity; the speaker voices his intention to return with his "new toys".
