Chernograd is a story-driven simulation game with multiple endings based on the player's decisions. The player takes on the role of an employee of the Citizen Tranquility Agency, monitoring the residents of the 15th district of Chernograd. Each apartment is equipped with a system that tracks citizen activities, and any detected violations allow the player to connect to the home and apartment using video and audio recorders to find the violator, compile a report, and send it to the Department of Truth Inquiry along with all the evidence.
