Aircraft, such as helicopters, create sounds that you can hear over head.


Every now and then a random event will occur creating sounds similiar to that of a helicopter that can be heard overhead, zombies are attracted to the sound and will try to follow it. This random event can be good or bad as it migrates zombies either away or towards your base.
