I want TWD in New York
Everyone above ground would be dead. Survivors living in the subway system with restricted travel in between stations. With a front entrance and a rear entrance constantly guarded 24/7 by armed individuals down both ends of a long length of tracks. Folks huddled together like the homeless in train cars that happened to get stuck on various lengths of tracks just as the undead attacked in mass. Basically an American version of the video game Metro: Last Light.
