With the occasion of updating Penumbra's moddb details, media etc I found one of Frictional Game's first games on the HPL engine. It's called Unbirth and it was never released, the game never managed to pass alpha stage. My friend Cheesezorz got motivated by it and decided to remake the game on the Source engine. I immediatly wanted to help, so I started filming the levels, which crash quite a lot. I managed to film all the levels, except some of the rooms. Regarding to the story, I think we must contact someone who worked on the game to ask him about it. So far, the original content is very usefull, especially the sounds and a few textures.
Here's what I managed to film:
