An adventure game for the SuperNintendoEntertainmentSystem developed by Human Entertainment. Known as ''Septentrion'' in Japan, the U.S. version was released by Creator/VicTokai. Basically take {{The Poseidon Adventure}} and turn it into a side-scrolling platformer and this is what you'll end up with. The Lady Crithania capsizes during a storm and it's up to you to escape with your life. Along the way you will encounter other passengers and crew who you must try to rescue... [[VideoGameCrueltyPotential or not]]. You have to escape within [[TimedMission one real life hour]] or it's game over.

You play as one of four [[MostGamersAreMale adult males]] trying to escape. Each character starts in a different part of the ship, and must rescue a certain person to get their good ending. Depending on your character's personality, passengers may come with you right away or refuse to come along at all; you must balance time spent rescuing people with time spent escaping. In general, [[EarnYourHappyEnding the more people rescued]], [[MultipleEndings the better the ending]]. With the exception of drowning, the only penalty for getting hurt is to Lose 5 Minutes, which is also the only time you get to see how much time you have left.

The game was hardly advertised at the time and not very popular.

!!Tropes associated with SOS:
* ArtificialStupidity: People in your group, once called, will all take the same path in the same way, even if that involves jumping to their death after seeing someone else do it or just getting stuck in the floor for five seconds before continuing normally.
* BlackoutBasement: After 30 minutes the ship's sinking speeds up and the power goes out on the upper (now lower) decks.
* {{Backtracking}}: If you are dedicated to saving certain people, you must sometimes go away from the exit to get to them.
* CoolOldGuy: Jeffrey Howell is a doctor in his 60's, yet can still jump, swim, and save survivors as well as anyone else.
* CrouchAndProne: You're required to crouch to get through small areas.
* CutAndPasteEnvironments: The staterooms.
* DeathCryEcho: The scream your character lets out when you Lose 5 Minutes.
* DownerEnding / BittersweetEnding: Depending on who your character is and who else you rescue, you don't always end up surviving even after you “get out.”
* EarnYourHappyEnding: If you want to get the best ending for each respective character, you'll have to escort many people to the engine room, as well as save one (or more) critical characters per individual.
* EscortMission: The whole point of the game.
* GameplayAllyImmortality: Played straight and averted. Straight in that people in your group are immune to some things that would cause you to Lose 5 Minutes, like fire and falling chairs, but averted in that they are not immune to falling or drowning.
* GuideDangit: Some of the survivors are very well hidden, and won't come with you if you don't do certain acts in a very specific way. There's also a dialog scene before the boiler room where you will lose all the survivors if you don't answer it correctly.
* HideYourChildren: Averted. You can rescue children, and they can die if you are not careful.
* InUniverseGameClock: You have one hour to escape the ship. After the 30 minute mark, some people can't be rescued, and others can only be rescued after it.
* ItsUpToYou: The rest of the people on the ship are perfectly happy to sit in one place as the ship fills up with water around them. Only you can convince them to actually try to get out.
* LargeHam: Redwin at times.
* MultipleEndings: Depending on who your character is and who you rescue.
* NeverSayDie: The word “perish” pops up entirely too often. Only averted twice – in the opening scrawl, and in one throwaway line where the character says “die” only because “parish” wouldn't fit on the screen.
* OptionalCharacterScene: Marie/Mary and her mother. Jack and his cousins. Luke and the captain. Capris and his sister. There are a lot of them.
* PaletteSwap: You'll encounter many dead passengers on the ceiling (now the floor) who look the same except for the color of their hair and clothes. Sometimes even passengers in your group will exhibit this.
* PointOfNoReturn: The boiler room.
* RunDontWalk: Averted. You can't run, you just move at a brisk walk
* SinkingShipScenario
* VisibleSilence: All the time in your conversations with passengers.
