RayCity has a new city, which was released last year. What's interesting about this city is that it is some night driving and the traffic is totally different some any other traffic found in other games.
Dark City features zombies aswell as all new missions and their are no NPCs around to talk too or to accept missions and deliveries compared to the main city Seoul in the client.
I included a video of a drve around (in HD of course). I think I'll let you guys form an opinion of the town yourself and the traffic orderly driving around.
