Outdoor escape game by Outside Escape โ not a physical escape room, but a puzzle route through Scheveningen that you play at your own pace with an envelope full of assignments and your phone. Dr. Otto Everhart allegedly worked in secret on a dangerous experiment in the bunkers beneath Scheveningen after World War II, with the plan to destroy Scheveningen and Den Haag with a superbomb. Players find an old suitcase with objects and a map and follow the clues to locate and neutralize the device in time.
