Story

After being attacked by a colossal sea creature, a small nuclear submarine is thrown into a high-stakes battle and must reach the surface before air runs out. Players take on the role of either Pilot or Mechanic and must work together to keep the submarine stable by communicating with each other, fixing failing systems, and navigating through perilous waters. Survival depends on the pair’s ability to work together under immense pressure. Failure is not an option.
