I just got done play a public match where it started with 4 players but everyone but myself quit. Instead of progressing through rounds, I thought i would look around. When I went to turn on the power I heard Maxis talking to me, but the further I went away from the switch room Richtofen started to talk to me, and I was playing as Samuel. Well I had seen that if you shot the jetgun at the clock in the diner the sign would light up, so I decided to see if it worked and as I was building the jetgun I kept hearing the Richtofen dialogue as if I was completing the story (I have completed neither side in the story). When I completed the jetgun and tried it on the clock in the diner, the sign indeed did light up and the more jet gun power used on the clock the more letters and longer they lit up. I was going to try to destroy the jet gun at the clock but I did not get to it. I had heard the dialogue to bring the jetgun to the obelisk, so after a few more rounds I did so, and again the Richtofen story continued saying it needed to heat up the obelisk. Now, keep in mind, I have not built the table in my profile, but I have built it in a friends, so the table is not built in the game I was playing and neither story side is completed. I used the jet gun until it was destroyed and it continued the story with Richtofen saying I needed to kill a lot of zombies at the pyramid. I died in the process of getting the kills so I don't know what would of happened next. Aslo, I forgot to mention I had the morse code on the tower and the sparking lights on it during this.
Now for my theories that have came about from this game.
I had the thought that the jet gun maybe fried the card-reader since in previous EE guides it was used on it. Which results why the nav cards do not work. Also, maybe you can use the jetgun to harness the Avogadro's power or use it to kill him maybe? Maybe you need to fully restore the power to the diner and maybe bus depot and have the signs completely lit for a part of the EE.
Like I said I just finished the game that all that happened in and made me think that the table has nothing to do with the EE and is something extra that we have to figure out. I hope someone can use this to maybe figure out a solution. Then again it may be nothing at all. Sorry for the grammar. If someone wants proof of any of this and does not believe me show me how to take the game footage and upload it for the proof. Thanks.
