1999: the luxury liner King Windsor has been struck in a collision and is sinking. Players alternate between the ship's navigator Gerhard Brown and chief engineer Carter, working to reach each other and rescue as many passengers as possible. The simulation takes the physics of a sinking ship seriously — the King Windsor tilts as it descends, and players must follow safety protocols to avoid sliding to their deaths. A map indicates where passengers are sheltering. The game tracks every person saved, and the number of survivors determines the ending.
