In the designer notes for this map, Christen David Klie wrote, that his wife made a small contribution to this map. He wrote: "And on an unrelated point, my wife, Gerrilynn, created the first ambush in the long, brown "blinking lights" hallway-the first and last contribution she ever made to any of my WAD files."1
