Far beyond the shipping lanes, the offshore platform LEVIATHAN drifts alone.

Years ago, a catastrophic industrial disaster tore through the massive drilling installation. Fire consumed entire decks. Systems failed. Compartments flooded. Workers vanished behind emergency lockdowns. Rescue efforts recovered only a fraction of those who had been aboard.

The company eventually abandoned the crippled platform and wrote LEVIATHAN off as a total loss.

But it never sank.

Now, weathered by years of storms, corrosion, and the relentless ocean, the enormous derelict continues to drift across the Blackwater region. Its decks should be empty. Its generators should be dead. Its corridors should contain nothing but rust, seawater, and whatever the recovery crews left behind.

They aren’t empty.

Lights sometimes appear aboard the abandoned platform.

Radio transmissions have been reported where no transmitter should still function.

Locked compartments remain untouched since the night of the disaster.

And deep inside flooded sections of LEVIATHAN, some of the missing crew may never have truly left.

Explore an open-ended maritime horror sandbox where industrial disaster, psychological terror, supernatural mystery, exploration, survival, investigation, and the unforgiving ocean collide.

Become anyone you choose: a sailor, investigator, engineer, retired offshore worker, researcher, rescue specialist, journalist, salvage operator, saturation diver, ROV pilot, or a character entirely your own.

There is no predetermined path.

There are no provided choices.

Your words, decisions, relationships, discoveries, mistakes, and actions belong to you.

Survive LEVIATHAN. Investigate its past. Search its forgotten compartments. Descend into its flooded pontoons. Discover what happened to those who were never recovered.

And if the ocean finally claims LEVIATHAN...

the story doesn’t have to end at the surface.

Some things remain trapped long after they reach the bottom.
