About the game

Descend into a breathtaking alien ocean and uncover secrets lost for over 11,000 years.

In Sinking Eternity, you awaken from cryosleep alone on a small island with no memory, only the distant echoes of an ancient mystery waiting beneath the waves. You must explore a vast, dangerous, and beautiful underwater world to survive.. and to discover the truth.

Explore the Unknown

Dive into sprawling biomes teeming with life, from vibrant coral forests and volcanic trenches to the haunting ruins of a forgotten civilization. Each location holds resources, dangers, and clues to an ancient story that connects you to this world.

Survive Beneath the Waves

  • Gather food, water, and crafting materials to endure the deep.

  • Upgrade your diving gear to withstand crushing depths of down to 2500m+ / 8200ft+ in Early Access.

  • Manage oxygen, pressure, and the ever-present threat of hostile creatures.

Build Your Ocean Refuge

Construct and expand your shelter on a small island. Craft tools, upgrade stations, and even invite friendly creatures to share your space. Your base is more than safety, it’s your lifeline.

Uncover an Ancient Mystery

Discover survivor logs, investigate strange artifacts, and unlock the hidden history of a long-vanished expedition. Every clue brings you closer to the truth, and deeper into danger.

Key Features

  • Vast single player world with handcrafted, vibrant environments.

  • Immersive first-person exploration with survival and RPG progression.

  • Varied biomes, from serene shallows to abyssal trenches.

  • Engaging main storyline with optional side quests.

  • Unique blend of peaceful exploration and tense encounters.

The deeper you go, the stranger, and more dangerous the world becomes.

Will you survive long enough to uncover the truth hidden in the Sinking Eternity?
