I have a theory for Nuketown zombies that may lead to an easter egg, i dont have a youtube account and im not very good with elite and theater so i will do my best to describe my theory.

on the sides of both houses there is an electrical meter with faint writings on it. (hard to make out)on the house with the fallout shelter the meter is next to the garage on the side of the house, if you examine it the meter has a wire coming out of it and it runs up the house and connects to the electrical poles and continues down the street. on the other house (the yellow one). it has a meter on the right side of the house (if looking at the front door from the outside)this meter has the same wire that connects to the electrical poles but it also has a wire connecting to the giant generator next to it. if you knife either meter then it will fly open and spark, same with the generator if you shoot it. most of the electrical poles are destroyed or on fire yet there is obviously a flourescent light still on in the kitchen of the yellow house. the power/electricity was very important in tranzit, turbine, both tower of babble etc. so maybe this is important as well. im thinking that maybe if you do something with the power than the fallout shelter may open or maybe something else idk. i know its not much and a little confusing but i feel like i might be on to something. please comment and let me know what you think!

one of the main people behind zombies recently tweeted about a possible second ending to zombies (other than just dying) this has caused a lot of controversy and everyone ive seen has tried to link it to tranzit but i believe its related to nuketown. maybe at the end, when the bomb drops you can somehow get in the fallout shelter and survive?!
