It hasn't been mentioned above but I think the bus in the middle of the map in nuketown is the bus used in tranzit. That's why it sounds close by when you hear it hoot. Also nuketown is pre tranzit. The zombies eyes are blue from the start in tranzit but are yellow to begin in nuke. I'm sure Richthofen says "I knew I should have invented a head moving robot" meaning the driver for the bus?? Maybe you need to create the robot in order to use the bus? There are two small wooden clocks upstairs in the house with the bunk beds. They are both on ten to 2. Anyone know if it's possible to move the hands of the big clock to match?
