Endless Ocean: Blue World

Take part in an underwater adventure in search of the mysterious Song of Dragons, which is said to be cursed...but also leads to a fabulous hidden treasure! Trek across the world with R&R Diving Service to exotic locales, including Pacific reefs, a South American river, sunken shark-infested shipwrecks, the icy Antarctic and even in the inky black depths well below the Red Sea.

The game features a main story to follow, but players can take it at their own pace, or decide to try some of the side-missions, such as dolphin training, filling an aquarium with fish to display, managing your private reef, mapping out areas you've visited and selling the maps for profit, salvaging treasure, pursuing special requests and treasure rumours, taking on photo requests for magazines, and even taking guided tours around locations you've already visited. Completing certain milestones in the game awards you "titles", which act as an achievement system. You can give yourself any title that you've unlocked to use as an identifier, and even mix and match them.
