As for the laundromat-door: I wouldn´t spent too much attention on this, (well i actually can´t pay attention to it since i´m on ps3) beacause i honestly think this is some kind of glitch either for xbox or ps3.
What I´m focusing on and what I´d suggest you to focus on too, are the orbs arround pylon/traffic light/mystery box.
I recently did the Richthofen side of the EE, like everyone I got a glowing box-weapon like in every single game and always killed bunch of zombies with it but never recocgnized anything special, anyway...
Yesterday i was logged into one of the accounts i did richthofen with and tried to do maxis´ side of the ee... i gotta say we died pretty often and didn´t manage do get it done,
BUT the second time we tried it, after the power was on and back off I saw the blue orb around the traffic light in town... we died soon that game and in the next the light was gone but i recognized something that might be important:
there are sparkles coming out of the traffic light that had the orb around it WHILE the power was turned on, they dissapeard after power was fully on and it was only on the one traffic light(the one across the curch).
Actually I have no Idea what it could mean but i think we could find out what triggered the orb to appear: It was obviously nothing that we did in one particular game because we did excactly the same stuff for 3-4 games and had the orb only once... So maybe it appears when you´re trying to switch sides? Like Richthofen telling you to stop ? Or does it appear after a certain ammount of time? Like when you did the easter egg you get the orb around traffic light excactly 1 week after(Im pretty sure it was 1 week on my game)?
Sorry for the huge post, but i just wanted to share my theories and I hope this might lead us to something :mrgreen:
