• The submarine begins stuck at the bottom of a pit on the seafloor with a broken ballast.
• The nuclear reactor has kept the most essential systems online but is critically low on fuel.
• You must fill the biofuel backup generator with spare fuel canisters to demonstrate the fuel system.
• The tutorial consists of familiarising you with the controls, ship layout, and repair mechanic with the goal being to repair the ballast.
• At first you will be unable to repair the ballast and must instead find an unusual method of increasing you buoyancy.
  • This phase would allow you to learn about navigation in a safe area before being exposed to the larger world.
  • Within the tutorial pit you are introduced to the resource collection mechanic. You must acquire scrap metal and collect/harvest local creatures to progress.
  • You will likely need to research and harvest the swim bladder of a large creature to gain the buoyancy.
• Once you gain buoyancy, you are able to ascend and leave the tutorial pit.
