Since February of 2013 we imprison voluntarily groups of friends, families, colleagues and students in the underground of Bern for an experience unique in Switzerland. Completely on their own, the group needs to explore the rooms, find hidden places, secret doors, and the meaning behind mysterious objects and devices in order to open the doors and finally regain their freedom.

Similar situations are known from films or computer games, but here the participants themselves are the main actors and you work with real, not virtual objects.

Do you accept the challenge?
