Discovery, Exploration
Samantha Rhodes finds a map and a book and learns of her grandfather's quest to find Atlantis, and tricks the Deep Sea Salvage Crew into helping her look for the lost city and find the magical keys that will unlock the Portal to Atlantis. After completing their quest and making their way into the city, as well as recruiting Dr. Brains into the salvage crew, finding the lost submarine the USS Ocean Odyssey and seeing that the Aqua Raiders had been very close to the lost city, they discover that Atlantis has been trapped in eternal darkness by the Dark Guardians, who have kept the Golden King prisoner since his capture by Hypaxxian forces. After finding all of the Golden Treasures of the city, the crew is captured by the guardians and taken the king's palace, who is a prisoner of his own dungeon. In an attempt to escape the palace and defeat the guardians, Samantha hatches a plan to send a remote-control submarine to the surface world and attaches her grandfather's journal to explain the situation. After receiving an unknown source of help, the five crew members defeated the guardians and helped rescue the city from darkness, and returned the Golden King to his rightful place as ruler of Atlantis.
