Fog offering rework
I personally have never noticed a difference between the fog levels. What if the fog offerings could actually substancially change the thickness of the fog, for example purple reagent would make the fog closer to Silent Hill kind of fog levels. Just imagine how the killer would walk out of the fog. If it's not too much but if the change is at least noticable that could bring some small amount of good variety to gameplay.
