The heart of the pirate (Der versunkene piratenschatz)

Hidden in the depths of the sea lies the pirate ship of Captain Jack Rackham. After a lost battle, everything he ever owned sinks: his ship, his crew, and also his treasures accumulated over the years.

According to legend, his treasure is cursed and now belongs solely to the sea. But you are adventurers and take on the challenge to find the pirate treasure. With a small submarine, you dive down and explore the wreckage of the ship. It seems as if the spirit of the pirate is still present, and you have only one hour to return to the surface before you run out of oxygen and the sea swallows you forever.
