Something I think would be super cool is for example you are a survivor trying to reach out to other survivors and you find an old radio station that could be broken that you can find equipment to fix it and broadcast on a frequency to allow other players in maybe a certain radius or even through the entire map to search the radio stations on an in car radio and find your frequency to hear what you have to say, maybe use a voip system for this. I think it would be an awesome way for people the recruit others or make a small town of their own kinda like the governor on the walking dead :P. I hope this is possible I personally would love this kind of feature in the game. You could even maybe have graffiti options or write on a wall with a message to let people know of your broadcast.
