All Killers are in first person perspective. This gives the feeling of dominance on their world and limited field of vision. Their main objective is to prevent Survivors from escaping and hang them on the Meat Hooks found throughout every level. Each killer has a unique mechanic of gameplay that differs them from the rest.
Killers can not scavenge for items, but they can complete their own Daily Rituals.
These things differ from time to time. But each acts in a similar manner, and with similar human traits. But they are reminiscent to beasts of burdens even though I can spot some flicker of humanity. With scars and marks on their skin and body. As if they have been self-mutilating themselves. They even look dead. I fail to see some humanity inside of them. They are bent in finding me. But somehow they refrain from killing me. Instead I'am hung from one of those dreaded hooks. I keep asking myself why they do not snuff the life out me themselves. But someone must control them. Might they do someone else's bidding?
— Benedict Baker's Journal, Nov. 1896
I keep trying to understand them at the same time as they stalk me. I try finding something that can pinpoint their purpose. I wonder if they might be punished? But in that case, am not I in the same position? Being punished for something, as I try to escape and find some way out of here. They play their role. Without any diversions, they are like finding a machine that is set on finding any living soul. Are they without hope? Who do they serve? Is there even a monster? I have never seen them rest or stop. They hunt until the hooks are occupied. But where do they go after that? Trying to find some answers is one of the few things that keeps me sane. For now. If you stumble upon one of these beings you must run and you must hide. Without any sound.
