hey who is this guy?

[Yuhaney]

This is The Hunter.
It was developed to be released with the Technology Demonstration of HPL engine.

However, the guy who worked with The Hunter, left the team before he got it finished and therefore, Frictional Games never included it into any of the games.
Since it's files are still located with the Tech Demo of Penumbra, The Hunter can be viewed in the model viewer and CAN be added to the game itself, but since it doesn't have animations of any sort, it doesn't do anything.
