You are a guard at an abandoned school. Your task is to keep order in this uninhabited place.
Turn on surveillance cameras to survive. The battery of the camera may become low and they will turn off. Therefore, do not forget to put video surveillance devices on charging.
Try not to get scared in the dark rooms of the school. Carefully peer over cabinets, desks and doors. Beware of the danger that can jump out of you from around the corner!
