As a professional diver named SILT, we'll explore a disturbing, monochrome world with dark undertones that make it even more terrifying! He tells disturbing stories about the underwater world and strange creatures simulated with real images. The journey to the ocean floor will not only be dark but also dangerous, as threats lurk everywhere: monsters, gigantic creatures, and raging currents. We'll also witness the rise of giant creatures. In these dark spaces, the only way to escape these waters is through telekinesis. Once activated, by searching for nearby fish, it will be useful for unlocking passages, but it will also render us helpless! Once unlocked, simply disconnect and continue! If we don't quickly find a way out, we'll be forced to face gigantic sea monsters. We'll be able to admire truly evocative scenes and participate in special puzzle-solving activities. New discoveries will help strengthen our self-confidence and courage. Along the way, a series of details related to the "power of Goliath"—the giants and ancient secrets—will be revealed.
