Everblue – a scuba diving adventure game – immerses users in the depths of an underwater setting, offering a unique and exciting experience. The plot centers on Leo, a novice scuba diver who, after joining a diving club, goes on a journey to discover secrets hidden beneath the surface of the sea. Leo is engaged in salvaging items from sunken ships, ranging from valuable treasures to necessary equipment. These finds can either be sold for currency in various stores, or used to improve Leo's diving equipment. Adding to the realism of the game is a complex dive simulation in which factors such as oxygen levels, depth and water pressure affect gameplay.

Above the water, gamers will find a lively city where they can interact with different characters, purchase items and complete tasks. The city reflects the dynamics of the setting, operating in a day and night mode with dynamic weather changes. Everblue's non-linear structure allows users to chart their own path across the ocean, discovering hidden kingdoms and secrets at their own pace. A distinctive feature of the video game is its extensive range of marine life, numbering more than 100 species, each with unique behavior. Leo's ability to capture these inhabitants through photography creates an additional layer of gameplay that allows you to earn rewards and currency from impressionable clients.
