Hardcore survival, facing natural disasters and monsters head-on
Resist a variety of bizarre calamities such as whirlpools, corruption, poisonous fog, and acid rain, managing life, hunger, thirst, and sanity, surviving each day and night in desperate situations.
Encounter Cthulhu-style mutated monsters of various forms, sneak to avoid them, or use weapons, traps, and items to slay them, collecting monster organs as essential resources.
Build freely, create your own custom ship
Deep-sea fishing, exploring sunken ships and ruined islands, salvaging survival supplies, rare treasures, and strange materials.
Craft weapons and equipment, expand your living ship, unlock new cabins and special functions, turning an ordinary boat into an indestructible sea fortress.
Endless exploration, immersively unveiling the Cthulhu worldview
Explore uniquely styled isolated islands and ruins, visit bizarre sea inhabitants, confront insane cultists, each voyage facing unknown dangers.
Gradually recover lost memories, peel back the ultimate truth of the world layer by layer, and ultimately face a Cthulhu-style ultimate choice: escape the abyss or become a part of it.
