Hunter Mod for Penumbra: Black Plague?

[GoreGrinder99]

Hey everyone, I have seen multiple posts around here and there about this "Hunter Mod" in which the first two Tuurngate Infected are replaced with the Hunter creature from the Penumbra Tech Demo. Is there still a valid link somewhere or does anyone know which files to replace to get the creature? But I also have another side question. When playing the Demo I had only seen two of those crawling/flying monsters and no Hunter. Is the Hunter only in the Demo after installing the 1.1 patch? I'd love to get the Hunter into the game, would spice things up a bit.
