Every new Freddy's game that releases pretty much takes a rusty hatchet to the Game Theory episode based on the previous one and I think that's beautiful
FNAF 1 GT: You are the killer and this is nightmares before death row
FNAF 2 GT: Phone guy is the killer and somehow kept his job
Fnaf 3 GT (Probably): The guy in the suit isn’t actually the killer but a child who didn’t actually die and grew in the suit until he died. And you are the killer, returned after 40 years.
