Endless Ocean: Blue World (known as Endless Ocean 2: Adventures of the Deep in the European version) is the sequel to the first game. The game expands on many of the ideas in the original, such as providing a larger story, and expanding the map into several different regions. Though the game takes place in the Republic of Paoul, some hints to the first game are made, suggesting that this game occupies a similar timeline.
The introduction starts right before the Cavern of the Gods is discovered. Before the dive starts, Jean-Eric asks if you are ready. Choosing "I'm the girl," or "I'm the boy" chooses your gender. You then customise your diver through information given. When diving, the basic controls are given. After swimming through the tunnel and seeing the entrance to the Cavern of the Gods, the prologue is over.
Chapter One, The Song of Dragons
A college student studying folklore is intrigued by the Song of Dragons , and by chance begins working for the L&L Diving Service. You start diving with Oceana Louvier in Gatama Atoll. During the dive, she drops her pendant that her father gave. It makes a weird sound and a humpback whale rushes at you. Oceana then decides to go by herself and find a piece of the pendant her father lost at Deep Hole. Jean-Eric gives you the pulsar for safety since a tiger shark patrols the area. After shooting the shark with the pulsar, it leaves and Oceana is revealed to be safe. She finds the pendant and returns to the boat. When joining Oceana's pendant and the new pendant together, a mysterious verse is found written on it reading "The road to the truth is the Song of Dragons."
Chapter Two: Phantoms of the Castle
When going to Nineball Island , your first dolphin partner, a short-beaked common dolphin, has been showing itself at the island many times before you joined. Ringing the Dolphin bell will give you the first training session.
The mysterious verse found on the pendant hints to the Valka Castle, a set of ruins at the Ciceros Strait in the Aegean Sea. While at the Strait, GG the famous salvager meets you, looking for the Valka Castle himself. He makes a bet, saying whoever finds it first makes the loser eats a sea slug (scrubs the underside of the boat with a toothbrush in the American version). While at a set of ruins, you run into GG, who quickly goes back to his boat. The answer to why comes when a fierce shark named Thanatos swims by. The pulsar has no effect on it and Oceana decides to hide in a well, but the well is actually part of the ruined Valka Castle. While exploring the castle, a picture of a flat earth leaves a huge impression on Oceana. Then, a wierd whale sound is heard: the Song of Dragons, and a door closes, locking you and Oceana in a room.
After finding out how to escape, a secret room is found containing a tablet made of lapis lazuli. You safely make it back to the boat. GG, having lost, never actually ate a sea slug.

Changes from the Predecessor:
- While the first Endless Ocean restricted players to a circular part of the map referred to in-game as the "targeted dive area" (with its position depending on where the boat was parked), and would not let them leave the boundaries of this area, Endless Ocean: Blue World allows players to explore the entire location upon diving from any point on the map, no matter where the boat is parked. (Though this is assuming that you've completed the main objective of the area in order to advance the story).
- Most of the more dangerous and hostile sea creatures from the predecessor make a return, where unlike the first game, they now pose a threat to the player, and most of them cannot be interacted with unless they are pulsed.
- While the first game only had one location to explore, (along with a total of four sub-areas each sporting their own map), Blue World has a total of six different locations to dive in, along with six sub-areas, making for twelve locales in all. Additionally, while the first game focused mainly on tropical coral reefs, the locales here are more diverse, allowing players to dive in areas such as the arctic, and even in freshwater. It is also worth noting that some of the types of areas present in the first game are now accessible without having to enter a sub-area, (such as Cicero's Strait's shipwrecks being scattered around the entire coral area instead of only being viewable in one spot).
- In the first game, whenever the player would grab onto a dolphin partner, they had no control where the dolphin went. Here, though the dolphin will still swim forwards automatically, players can control its direction. Also, riding on the dolphin now provides a speed boost.
- Some of the returning sea creatures from the previous game have updated and/or more realistic models/animations.
- Additionally, the habitats where some of the returning animals are found are different in order to replicate their real-world counterparts as closely as possible.
- Also, the game places a larger emphasis on cutscenes that depict animals performing their natural behaviors.
- Players can now take pictures in different lighting styles, (black and white, sepia, etc.).
- Endless Ocean only allowed players to keep up to three dolphin partners. In Blue World, players can keep one of every species, (11 species in total).
- Befriending dolphins in the first game was rather easy, as simply petting and feeding a dolphin enough would make it like you, and then you could enlist it as your partner. In Blue World however, befriendable dolphins only appear at specific points during the game, and only certain specimens (distinguished by unique markings) can be enlisted as diving partners. Also, the conditions that need to be met in order to befriend a dolphin are much more complicated now.
- In the previous game, the player could zoom in on just about any spot on the sea floor, while in the sequel, only certain spots can be zoomed in on.
- Blue World now enables players to dive at four different times of day instead of just day and night.
- When training dolphins, tricks can now be selected, unlike the first game, where the dolphin performs tricks randomly upon being given the command.
- Additionally, when performing a trick, only the dolphin you've selected to train will perform it, while in the first game, all three enlisted partners could be seen performing the trick in unison at times.
- The game has a lot more legendary sea creatures.
- In Endless Ocean, petting/feeding any animal for a long enough time would make it like you. As a result, animals who have been pampered enough will often follow the player around. In Blue World however, animals do not do this, and feeding and petting them enough will only enable the player to learn more information on it.
- The same goes for learning the animal's species. In the first game, the player had to rub the animal enough in order to identify its species, while here, the animal's name can imediately be learned upon clicking on it.
- In the previous game, upon spotting a treasure, you could immediately tell what it was. Here however, the game tells you that you found a generic item, and collected items must be appraised in order to identify them.
- The player now has infinite fish food to give to animals, and the camera has unlimited film.
- Unlike the first game, where the player could only dive alone or with a befriended dolphin, this game allows them to dive with humans, with each human partner having unique strengths beneficial for completing the game 100%.
