A better video. It has been mentioned that the colour of the text displaying the main agent’s thoughts can be a little misleading. The colours actually refer to the spinning markers, and not the the enemy agents. This has been remedied in the latest build which is available on the downloads page. (VS2010 and DirectX10 required)
