Footage from the video game "The Suffering: Ties That Bind" released in 2005 and developed by Surreal Software. It's the sequel to "The Suffering: Prison is Hell".
This pre-alpha version is from Chapter 3. For reasons I forget, this was replaced with the truncated one in the final release: http://www.youtube.com/watch?v=KC0_Z06rTdU. Since all the original geometry still existed, it was fun to re-construct what the pre-alpha version was.
Be sure to have YouTube's Annotations on to read notes about each section.
In retrospect, both versions are a little too much like a cramped carnival ride -- a new event every few feet that you can only watch.
