You actually play as the entity? (for killers anyway)
This has probably been speculated a thousand times, as I used to think about this but never discussed it. However with the new release of Pyramid Head, I pondered a bit. So to cut to the chase, Pyramidboi can get flashed. Even though you know, his face is covered.. I think this is because you are in actuality playing as the entity, looking through the "eyes" of the killer. This is confirmed with the red glow, obviously. ALSO.. when you do your mori as a killer, the "camera" goes in a 3rd person perspective, watching the killer take a life by their hands. Just a thought!! lmao
