The game can be played on three difficulty modes: easy, medium, and hard. In the game, you'll control Shamu, taking instructions from Horatio. You'll need to manage Shamu's health bar, oxygen bar, and agility percentage meter. A higher agility percentage will allow you to perform more animal behaviors. Gameplay involves swimming around, collecting items like krill balls and oxygen to replenish your resources, while avoiding sea mines, solving puzzles, battling the kraken, and exploring Atlantis.
