A discharged veteran takes a job as a night security guard at a local school, hoping the quiet hallways and still night air will finally bring him some peace. Late Night Duty is a short, linear psychological horror walking simulator set in Malaysia, following his first shift. Report to the security post, collect your flashlight and patrol scanner, and check in at all designated points around the school. As the shift deepens, the line between hallucination and reality grows harder to find.
