I don't know what to put here for a description--Read more >
According to one of Scott's announcements(which is now deleted to avoid confusion), whatever will come on Halloween will not expand on FNAF 4, meaning that the case or Nightmare will never be explained, and that it won't be a sequel, or a prequel. If it won't be any of those, then it's safe to say that it will not be FNAF related, but we could hope for it expanding on one of the other FNAF games, although that seems unlikely.
So I suppose all we can do is theorize what those two secrets are, and by extent, Shadow Freddy and Shadow Bonnie.Read more >
Both of them include Springtrap, and both utilize the need to change the contrast. I choose Springtrap because not only is he my favorite, but also because there's plenty of hints about him surviving Fazbear's Fright's fire. Everybody knows that, anyway.
And yes, the second one is a homage to FNAF 3's first teaser. Hope these look good.
