Hi, this is my first post so it may have a crap load of flaws with it. I have been lurking here for about 3 months, but have finally decided to join. So, my theory is about how the crew gets to the maps, considering there is not a teleporter in every one of them ( like ascension).
Ok, my theory is that Richtofen has a pocket teleporter that expands when put on the ground so everyone could fit on it. The reason that they have to stop at a map is because the teleporter needs 115 to operate. Since there is a wonder weapon in every level, I believe that each one has some 115 in it, so they have to shoot in into the teleporter, kinda like how the wonderwaffe overrides the teleporter in der riese. Once they do that, they can teleport to somewhere else when they are being over taken by zombies or an instance like that.
