Zombies are basically humans with a partial brain and consist of a large nation with a monarchy having a Zombie King to rule over all of the zombies. Since they were born after the noobs, many of the zombies weren't able to steal much advanced modern technology from the humans and instead had to develop mostly everything from the ground up. Even though this is considered a huge disadvantage, the zombies were still able to compete directly with the noobs even now and they often run their kingdom.
