I'll admit it—I pulled the trigger. The game had instructed me to follow the lead of my fellow terrorists, and I had been told that preserving my undercover status was important for the country. But after an introductory gun burst, I couldn't do it anymore. It was the most powerful emotional experience any video game has ever given me. I don't know that I cried, but I was knocked off balance by emotions that I thought I had tucked away. As the travelers screamed and fled from the indiscriminate slaughter, I strolled through the airport. I didn't fire my weapon anymore, but I watched the three Russian terrorists kill. One of the men shot a passenger as he crawled along the blood-streaked floor and pleaded for his life.
