Sam Fisher- Photosensors

  I decide to begin at the end of the complex near the lake—the Tirma building and Basaran’s office—and then make my way back this way. The key is to stay in the shadows. My uniform is embedded with photosensors that detect and let me know how much light falls on me. When I switch on the OPSAT meter, I can see exactly how invisible I really am. At the moment I’m at thirty-two percent. It’s very luminous throughout the compound, and my only screens are the broad shadows of buildings, cast by the floodlights. Walkways between buildings are so bright it’s like daylight.
