Do you have what it takes?
For centuries, an occult group has protected unpopular scientific ideas and the thinkers who shared them. Now it's time for a new generation of free-thinkers and puzzle-solvers to take up their mission. In order to prove yourself worthy, you must uncover the identity of their most famous member, known only as A Secret Sender.
In this outdoor escape-type game, clues embedded in the city's architecture and myths will lead you past popular landmarks and lesser-known places of interest. Along the way, you will discover Amsterdam's historic center and investigate one of the great mysteries of Amsterdam's Golden Age.
