POTENTIAL SPOILERS:
Just entered zone Eden and got to the playground area. As soon as I descended the stairs into the playground area, an ear piercing static noise that occurs about 3 times per second, continuing seemingly indefinitely, will not cease. It is such a loud, high trebble, high pitched, raspy static noise, that I instinctively flung my headset off instantaneously and shouted expletives in my apartment for minutes on end. Must have been the same frequency as the “brown noise” because I think I sh*t myself. Happens with multiple headsets, my sound bar, my 2.1 Logitech speaker set, ear buds, you name it. Definitely a fault of the game because it only does it after that playground area. If I backtrack up the stairs, it stops.
This game has some really strange bugs. Like some real off the wall sh*t.
