It is a good idea to implement this, I want to use the walkie talkie as a tool of distraction, to place a receiver in the street and in an emergency can say a few words to attract the zombies with noise. also a good idea for when you want to do a diary of recordings, mostly of interest to those who like to give an atmosphere of survival with a back story of our experiences, even for those who would make video on youtube can make good stories with this material, advice or any anecdote record. It would also be great to get Cassettes in houses or warehouses, with recordings of some survivors tell their stories or their goodbyes they could be scattered on the map, would be a good way to get some entertainment in a world without human contact.
