Everblue , released on the PlayStation 2, is an action-adventure game that follows the journey of Leonardo, a professional salvager and diver. After washing up on a Caribbean island after a storm, Leonardo and his partner Zucco must repair their boat to escape the tropical paradise. However, they soon discover that a large corporation is planning to buy out the island, ousting its inhabitants and using it for their own money-making schemes.
As Leonardo explores the ocean in first-person using radar to find valuables, he encounters various environments such as sunken ships and crashed airplanes. By collecting these items, he can improve his gear and enhance his ocean exploration capabilities.
The game features a unique system where players must manage their health (HP) and air meters while traveling underwater. If the air runs out, HP will decrease, leading to an inevitable outcome. Players must navigate this delicate balance to progress through the game.
