Ok, in the new video there is a QR code which leads to this website. The images fade and you get a glimpse of the background which look like this. And there is also a clue in the source code: "Forbidden Knowledge doesn't come easy. To unzip these lips you'll need to take a long hard look inside."
So, I opened the image with winrar and found this image.
It is called insanity.png. I can't seem to find anything in there. Maybe it means that Wilson has a mental illness which makes him hallucinate the monsters? The filename and the shadows of the monsters instead of the monsters seems to point in that direction at least.
Here is the QR code for anyone who wants it: http://imgur.com/fRw8oljRead more >
I decompiled the scripts some time ago and haven't done much with them. Anyone who wants to add information from those scripts can find them here (outdated).
