The deep is awake — and it’s hungry.
Starry Studio has officially unleashed Isles of Abyss, the largest free expansion yet for the open-world survival hit Once Human, live right now across PC, PS5, Xbox Series X|S, Android, and iOS — and you can dive in completely free. Build your ark, sail into a haunted ocean, face terrors from the deep, and uncover the secret of the Sunken Lord.
Your Ark, Your Fortress, Your Lifeline
Everything begins with your ship — a fully modular floating base you design, upgrade, and command:
- Freeform Shipbuilding — mix hulls, decks, engines, and decor to create a vessel uniquely yours. Sails, electric drives, and boosters power you across the waves
- Arm It for Battle — harpoon cannons, long-range deck guns, rapid-fire batteries, frost launchers, and naval mines. Phase 2 unlocks rocket launchers and oil drum deployers
- Living Base — research benches, storage, crafting stations, and defences all at sea. Upgrade from a humble raft to an armoured dreadnought
Five Regions, One Sentient Ocean
This isn’t just water — it’s a living, predatory entity known as The Sunken Lord, and it’s watching you:
- Five Distinct Ocean Zones — from sun-dappled shallows to lightless abyssal trenches, each with unique resources, threats, and biomes
- Three Layers of Survival — sail the surface, explore island chains, and dive into the crushing dark below. Treasures and terrors wait at every depth
- The Sea Reacts — ghost ships drift in the fog, unblinking lighthouses pierce the dark, and storms shift without warning. The ocean itself is your greatest foe
How It Plays — A 21-Day Cycle
The scenario runs in roughly 21 days, split into two evolving phases:
| Phase | Focus |
|---|---|
| Phase 1 | Explore, gather, build, and unlock the map. Purify the ocean to advance — the faster your server progresses, the sooner Phase 2 begins |
| Phase 2 | Face deadlier threats, unlock advanced ship weapons, and unite with your entire server to confront the Sunken Lord itself |
Team up with friends or join forces with strangers — some challenges demand coordinated effort.
New Gear, New Horrors
- Combat Ready — all-new weapons and armour forged from ocean resources
- First-Person OTS View — new perspective option for closer, more immersive encounters
- Halloween Wonder Night — limited-time seasonal event running alongside the expansion
- RaidZone Mode — a brutal condensed version of the ocean challenge for faster, harder runs
Ready to Set Sail

- Cross-Platform — PC, PS5, Xbox Series X|S, Android, iOS — all progress carries across
- New & Returning — fresh players jump straight into the expansion; veterans can pick up right where they left off
The horizon is calling. Build your ark, sharpen your harpoons, and find out what lies beneath. But remember — the ocean isn’t empty. And it’s not alone.
