OK No! I've just found a video showing where the button is but it is absolutely NOT on my screen. The doorframe is completely blank, nothing at all to be seen so what the fuck do you have to do make the stupid button appear. If the entire plot direction is intended to go along this secret path why make it so fucking hard to open and why doesn't mine even have an opening mechanism. Everyone keeps talking about this Hiberheim place but I figured that was after the forest (zone 2) where the fuck is it otherwise?
Seriously there is no goddam switch in the game I'm looking at.
