Hideo Kojima's interactive teaser P.T. has been a hot topic of discussion for the past week and a half. While part of the talk has been centered around the great experience and the reveal of Silent Hills, many have just been trying to clarify what exactly is happening with P.T.'s final puzzle.
There are a lot of different methods circulating as to how exactly players can trigger P.T.'s end sequence. The problem is that none of them are really consistent. This video may have it all figured out, applying reasoning for the steps instead of blindly stabbing in the dark. There may be a few leaps in logic, but at least it all seems plausible -- especially for something that Kojima created.
