In 2048, technological development has become unregulated, and dangerous technological developments have changed the pattern of crime. The police are defenseless and law enforcement has implemented new strategies to combat all types of crime, but not all people are created equal. The design concept of the DRN series of robots is to be as close to humans as possible. They are based on a project called "Synthetic Soul". Known as the "Mad Robots", they were all replaced three years ago and replaced by MX series robots. Today, all police officers, humans and robots, are fighting on the front line for human safety.
