I dunno if this is well known, but I was driving down the bridge in Utah when I heard weird noises, like, either a wild animal or some sort of native american call. Sort of a Chirping/yelling.
Thats what I thought. Maybe someone could data-mine the game to find hidden sound files or something?
what do you think? --- Post updated --- I keep listening to the sound, but the more I listen, the more I can't understand and goosebumps... --- Post updated --- It may simply be that the developers put animal sounds that are unknown to us.
