Just Until Morning is a first-person horror game set during a single night shift at a 24-hour rural gas station. From 23:00 to 07:00 the player serves customers at the register, restocks shelves, takes out the trash, resets a faulty pump and watches four CCTV feeds that sometimes show people who are not there in person. There is no health bar: unanswered calls and ignored camera intrusions put the station's lamps out one by one, and a station left too dark ends the shift early. A full night takes about 80 minutes and can end in seven different ways.
