So as many people are starting to believe, the ranking system in zombies is based mainly around your k/d ratio and various other factors. Well i was watching one of the first zombie trailers we got back when zombies and tranzit was announced and at certain points in the trailer it shows you the whole map of tranzit and like the bus going along route and when it stops at certain locations it is marked with what we have come to know as the zombie rank emblems. So im wondering maybe playing in a particular area more or doing certain things in a specific area of tranzit account to what emblen you get cos it seems the emblems go up for difficulty of the area. For example shotgun emblen being the hardest emblen is in fact the town and if you think about it there is no weapons in town on tranzit so it in fact would be one of the hardest places to survive plus it has the most fire then any other area. Its just a theory but let me know what you guys think.
