Ubåden [The Submarine]

In the submarine, your group is divided from the start and trapped at each end of the submarine. There is at least one person from the group who must crawl through a pipe, have a normal build and not be afraid of small spaces. The submarine differs from our other escape rooms as there are several puzzles going on at the same time. That's why communication is the key to success, and if you can master this, you might get out before the 60 minutes are up!
