Just wanted to let you know, on the bridge that drops down into the spawn room with jug, if they are not random spawn perks. The windows are free to jump on and you can just sit there completely safe and zombies will come to the windows and just sit there. the right windows facing the hole is the one i jumped onto. easy to do, no stupid glitches or tricks literally just jumped up and sat there. if you fall you die eventually cause it probably detects you are outside the map.
