Video rendered using the opengl32dll.hack that disables walls illustrating the cheating going on by Adrian.  When you see his point of view without walls it becomes really clear how he operates without any sound cues.  This video illustrates just two examples, but overhwelmingly.  The demo is riddled with alot of content like this, and it would be an excercise in futility to go through it all and show the countles examples in the demo.
