The sunken pirate treasure

Hidden in the depths of the sea lies the pirate ship of Captain Jack Rackham. After a lost battle, everything he once possessed sinks: his ship, his crew, and also his treasures collected over the years. According to legend, his treasure is cursed and now belongs solely to the sea. However, you are adventurers and rise to the challenge of finding 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 only have one hour to return to the surface before you run out of oxygen and the sea swallows you forever.
