Plunge underwater and explore the sea in this diving adventure game. Accomplish tasks in the realistically-rendered ocean environment, diving down for underwater mysteries and swimming through the dangerous depths to complete challenging but necessary tasks. Hunt the sea's predators, bring up treasures and lost artifacts from the ocean floor, or photograph the previously unknown behaviors of aquatic life. The game features both arcade-style and simulation-style diving gameplay, with real diving equipment and a day-night cycle on 15 real dive sites for true-to-life experiences. A system of training and research video courses lets you know more about underwater diving.
