"The Quantum organisation has people everywhere: your friends, your colleagues, your boss. M needs your help. Phones are compromised. The secure BlackBerry network is no longer trusted. Something new has to be tried. Twitter. No one quite knows who to trust anymore, but there will be allies and there will be traitors."

The game is one you can dip into or out of, or play all day. An unlimited number of players can play, following M on Twitter and then solving the missions over time to get more clues about who the evil mastermind is, what they're planning and how you can stop them. You won't be alone, allies and enemies will follow you, and capture is never far away.

You'll need an internet connected phone with a good Twitter client so you can get your missions by direct message and can reply to M. Sometimes you'll need to send a photo back to HQ as well.
