Hey!
For ADOC 2006 we have created a small video that demonstrates the physics technology used in Penumbra: Overture. For those familiar with the tech demo of Penumbra most is familiar, but you do get a first peak at some ingame action from Penumbra: Overture.
Download locations
Here are a couple of locations where you can see the video, the locations hosted at frictionalgames.com will be removed as this years ADOC event ends.
