Beginning in the in the SeaWorld Adventure Park, this underwater action-adventure sends players on a magical journey, in the role of the famous orca mascot, Shamu. For some reason, Poseidon, the god of the sea, seems a bit jealous of the magic and fun that the killer whale brings to his water-park home, and he wants to steal it away for himself. As the heroic killer whale, players must explore the underwater world, search for clues, solve puzzles, and eventually face Poseidon and his mythological minions in head-to-head combat.
