Ok so I downloaded this some time ago and just actually played it yesterday with my friend online. Now since I only thought this was a re-skin and nothing else I had thought nothing of it. But as I was playing No Mercy on Expert I was a little on edge. As I got around to the middle of the map cycle (before you enter the hospital) I would occasionally hear "Where is everybody?" and not knowing if I was hearing it correctly or going insane, I asked my friend which, he said, I was going crazy. But after freaking out I checked my Volume Mixer to see where it was coming from, that didn't help. After trying to ignore it we had left the area in which we were hiding (I was trying to figure it out) a Shrek appeared from nowhere. After we died I didn't hear it until sometime later which would result in another Shrek. I don't know what was worse, hearing "Where is everybody?" randomly in a soft pitch and not knowing what it was or "Where is everybody?" leading to a Shrek.
