imagine a killer with the holo pilot skill from titanfall 2

That's why I think FNAF would be a great addition (gameplay / mechanics wise):

Gameplay:

• 4 animatronics on the map.
• With a button press you can make them all do an idle animation while they say something creepy and they face the next survivor near them (like hag).
• If you stand still your animatronic will do the same animation, but you can also use it while moving to make the others do the animation.
• Doing it while standing still you get the undetectable status.
• After charging the animation for at least 3s standing still you can swap into any animatronic.
• After swapping or moving, all animatronics will have a terror radius, move 33% faster and chase the nearest survivor (straight line) for 3s. After that they turn off with a creepy animation.
• You can also turn off yourself which makes you undetectable but decreases FOV to 50% (like a black screen with a little hole in the middle)
• Survivors can "temper" with turned off animatronics (takes 15s) completely disabling them for the next 45s

This would be terrifying and you could do really cool mindgames.

Survivor strategies:

• Survivors can counterplay it by bringing any obstacle between them and any animatronic near them
• They can just hide once the animation starts
• They can disable the turned off animatronics

Killer strategies:

• Killers can fake turn off luring survivors to them who try to turn them off
• They can fake play the animation to swap
• Or actually swap bodies and chase someone
• Or swap bodies fake chase someone for 3s and turn themselves off so nobody knows who the real one is. (This can be done multiple times to confuse survivors and "patrol" between gens)
