The cities of the world have grown into enormous metropolitan areas. To keep control of the ever-expanding population and the running of the biggest of these huge new city-jungles, the government has sealed it off completely. Each living soul in the city is a registered citizen, whose every step is watched over and directed by an Artificial Intelligence hive in charge of the city’s functioning.(Storyline via IGDB)
