Sea World: Shamu's Deep Sea Adventures is a Nintendo GameCube game released in 2005 in North America and later released in Europe in 2006. It was released prior to the new release of the Sea World Shamu show, Believe.

Plot
A vicious god of the sea has released the Kraken to take on Sea World. Horacio, a narrating manatee visits Shamu's show and tells him what he should do. Later, the Kraken from Atlantis was called from the Underworld and was about to take Sea World. Now our world ended many years, it's up to Shamu to destroy the Kraken and Poseidon.

Gameplay
Players take place at nighttime to play as Shamu, a killer whale named after the female deceased one. He must complete some missions and they are very similar to Game Center's achievements. Sea Mines will act as threatening obstacles in the game. Shamu must destroy the Sea Mines that Poseidon planted to stop him. He also has to destroy the minions of Poseidon to complete a mission. They are summoned from the Underworld and must be destroyed.

You also must collect all the Kraken Krystals as the mission states. You must solve the puzzles to open other doors. You can find the extra content to get a hundred percent to avoid wasting your score. You can also buy the extras if you're having trouble finding the Kraken Krystals.

If you lose on some levels, like when you're on the Kraken Chase, the Battle of Poseidon and following the characters, you won't be able to continue the mission. You must avoid losing and need to collect all the Krystals.

In addition in the City of Atlantis if you swim up, the guards will spot you and you won't be able to continue.
