Once Human: Isles of Abyss Launches on PS5

Once Human: Isles of Abyss launches on PlayStation 5 on October 22, 2026. Announced on October 21 on the PlayStation Blog, it is the largest free expansion for Once Human yet, adding five brand-new oceanic regions to explore.

Key Takeaways

• Once Human: Isles of Abyss launches on PS5 on October 22, 2026.
• Isles of Abyss was announced on October 21, 2026, on the PlayStation Blog.
• Isles of Abyss is the largest free expansion for Once Human yet, with five new oceanic regions.
• The ocean in Isles of Abyss is a living conscious entity called the Sunken Lord.
• Regional bosses in colossal towers lead to a final confrontation with the Sunken Lord.

Once Human has built its following on strange, open-world survival, and Isles of Abyss pushes that premise into the sea. The expansion's headline idea is that the ocean itself is alive — a conscious entity known as the Sunken Lord — and everything players meet on the water is, in some way, part of it.

What Is Once Human: Isles of Abyss?

Once Human: Isles of Abyss is the largest free expansion for Once Human yet, launching on PS5 on October 22, 2026, with five brand-new oceanic regions to explore. It takes the game's survival gameplay to the open sea, where the ocean itself is the central threat.

The expansion is free, which makes it an easy return point for lapsed players and a low-risk starting point for newcomers. Five new regions is a substantial addition on its own, but the expansion's identity comes from what connects them: a single living ocean that watches, reacts, and manifests itself in the world.

Who Is the Sunken Lord?

The Sunken Lord is the living, conscious ocean at the heart of Once Human: Isles of Abyss, manifesting itself through Towers — staring lighthouses — and Voyagers, ghost ships that roam its waters. These manifestations are how the entity makes its presence felt across the expansion's five regions.

The Towers are among the expansion's most striking images: lighthouses that stare, turning a familiar coastal landmark into something watchful and wrong. The Voyagers, ghost ships drifting through the ocean, serve as the Sunken Lord's other face — encounters on the water that are never quite ordinary. Together, they make the ocean feel less like a setting and more like an antagonist.

What Threats Will Players Face?

Players in Isles of Abyss face dynamic threats including suffocating fogs, black tides, and skies raining temporal fire, alongside regional bosses housed in colossal towers and a final confrontation with the Sunken Lord. The environment itself is hostile, not just the creatures within it.

The dynamic threats change how exploration works. Suffocating fogs limit visibility and safety, black tides reshape the danger of the water, and skies raining temporal fire punish anyone caught exposed. On top of that, regional bosses waiting in colossal towers give each region a climactic fight, building toward the final confrontation with the Sunken Lord itself.

Is Isles of Abyss Free?

Yes, Once Human: Isles of Abyss is a free expansion, described as the largest free expansion for Once Human yet, launching on PS5 on October 22, 2026. Players do not need to buy additional content to access the five new oceanic regions.

That free positioning matters for a live-service game: expansions are often where returning players decide whether to come back. With no purchase barrier, the question is simply whether the new regions and the Sunken Lord storyline are compelling enough to dive back in.
