Penumbra Overture monsters probleme

[Sexbad]

Those monsters were only available in the tech demo.

And the second monster never even actually made it in-game. Its designer left before it was animated fully, I believe.

Though I think I recall it's actually in one of the TD levels, but it requires some noclipping to reach. One user here named tonewww(wwwwwwww(wwwwwwww?)) took the creature's files and copied them to BP and replaced the Tuurngait's with them. The end result was the model you see in the second link, but with Tuurngait sounds, Tuurngait AI, and completely fucked bipedal animations applied to a quadrupedal model.
