SOS is a survival game for the Super Nintendo where players assume the role of a character aboard a 20th-century passenger liner that encounters a storm and capsizes. Players must navigate the wrecked ship's flooded corridors, rescuing passengers and guiding them to safety while managing the rising water level and limited time. The objective is to save as many passengers as possible.
