South Night City area is basically an heavily industrialized port city with one of the last oil refinery terminals in the area, a container shipping port, the Night City Municipal Sewage Treatment Plant and miles and miles of cheap, shabby housing constructed at the turn of the century by Mob-controlled contractors.
It is a dangerous place. If you're not taken in a dark alley by one of the many gangs that roam the urban sprawl, it is quite likely you'll be shot by some trigger happy local mistaking you for a member of one the aforementioned gangs. It's always a good idea to travel here during the day. At night the fireworks start, and usually the ambulances don't come till the morning. Security here varies by location; some places are literal fortresses, with heavy firepower protecting them, while others just seal themselves in behind thick doors.
