The game can be played on three difficulty modes: easy, medium, and hard. In the game, you'll control Shamu and take instructions from Horatio. You'll also need to manage two bars: a health bar that needs to be replenished, an oxygen bar that needs to be filled up to keep going, and an agility percentage meter that affects how many Animal behaviors you can perform. Your goal is to swim around, collect items like krill balls and oxygen, and explore Atlantis while avoiding sea mines, solving puzzles, battling the kraken, and more.
