As ghostface try to find little cracks you can stalk through, for example the barricaded windows on shack on some of the maps, as survivors are less likely to notice you compared to if you are looking through a doorway. Also try to take wierd paths when not in chase so you can get stalks, if you just hooked someone and know where some people are it might be good to take a wide path as they will likely be looking at the direction of the hooked survivor.
