Voll Unter Wasser [Fully Underwater]

Permanently Closed - In 1959 we are in the middle of a secret exercise to test the new and very quiet submarine Nautrion. After completing all exercises, you as the crew of the Nautrion have the task of bringing your submarine back to its home port undetected. If there wasn't a loud noise that thwarts your plans. One of your crew members follows the sound and finds a technical problem. You look at your instrument panel and realize that something is wrong with the oxygen levels and your rescue gauge has gone out. You run to the bridge in a panic and discover your crew drunk and asleep on the ground. All efforts to wake her up fail. The oxygen reading decreases every minute. You waste no more time and take the problem into your own hands. You calculate that you still have 60 minutes to trigger the alarm. To do this, you have to solve the technical problems. Can you make it in time?
