Work as a forensic investigator, performing real-world investigation on a military-grade conspiracy. Yes, in the real world! The game redefines the way you play. It doesn't run on software. It runs on evidence, on your brain. You start with a SMS message from Mark. From there, you'll replicate his mission, find what he found, live the adventure he lived. You're on your own. You just have your own device. You set your methods, your pace, your tools. A piece of evidence helps you discover a part of the story, leading to more evidence, making you progress. Your challenge is to find the truth. The truth is out there, on the Internet. The Internet is millions of times bigger than a computer game sandbox. Are you up to the challenge? You might find answers in a news story on CNN or the New York Times. Something about a real company or person might help you proceed. The president might be involved. It's so intertwined with reality you'll be left wondering if it didn't really happen.
