For those of you who haven't heard yet, the Main Menu background music holds a little secret.
Multiple people have reported hearing a 911 call for someone who was heavily injured after modifying the pitch and other things of the sounds in the background. This call has been traced back to a real 911 call where a person got their leg amputated in an industrial accident.
Just incase people didn't know this, I wanted to make a blog about it. I am also adding it to the Easter Eggs page.
I will add more to this if there is any info that is found later on, or any that missed.
