I agree with you it was that very same part that scared the ba-jesus out of me I like you started the generator and got the H3LL out of there ASAP. My second scariest part was in the in the bottom of the goldstone building where you see all the clickers….That part was very nerve racking especially on survivor mode.
That was pretty scary. But I think it was mostly for unexpected jump scares. However, I felt that the basement full of clickers and that one bloater was the scariest. they seemed to be the most unpredictable. You never know when they spot you. It also has a strange psychological scare to it as well
