A mysterious suspect is terrorising the city, and it falls to you to follow the clues like a real investigator and unmask them. With a GPS smartphone you make your way to locations around town, solve riddles and decipher, step by step, a GPS code that brings the unknown figure into view. Secret phone numbers, a helpline and hidden clues put you back on the right track.
The catch: every investigating group is given too little information to reach the culprit on its own. The missing pieces sit with the other groups, who have exactly the same problem. So you negotiate. Which answer do you give away, what do you ask in return, and with whom do you form an alliance that will still hold later on? Playable in Dutch, French or English, or in a combination of the three.
