What surprises can be waiting for you when you are working as a security guard in a Japanese office building? Strangely, but this time you won’t be facing any robbers or any other sort of criminals. Something more appalling and perilous is lurking in the darkness of the offices that are supposed to be closed.
The game combines awfully realistic situations and an uncanny presence of the unknown. The way you will be dealing with the problems of this weird shift fully depends on you. Interact with various items and accomplish the tasks, contemplating creepy detailed surroundings at the same time.
Travel from one floor to another, closing the rooms and kicking out the workers who stayed late and refused to go home. However, at some point, something will seem odd. What is constantly following you and how to drive it out without being captured?
