From introduction(user translated):
The city in 2089 is a self-sustained world with sparks of life and light that hides in the darkness of crime. Steel and glass constructions glow in the light of the neon signs, and the streets and bridges are set on fire by the sweeps of the searchlights.
In this chaotic world the mega cartels are about to drown in their own automated swamp. What would happen if an even bigger disaster then the current one, would break ut.
