Once Human's free Isles of Abyss expansion launches on PlayStation 5 on October 22, 2026, developer announcement published on the PlayStation Blog states. The studio describes it as the survival game's largest expansion to date.
The expansion spreads across five oceanic regions. Players begin on a starter island and then choose the order in which they take on the remaining four. The ocean itself is portrayed as a conscious entity called The Sunken Lord, served by lighthouses known as The Tower and ghost ships called Voyagers.
Building plays a central role: players can construct and upgrade a customizable mobile base vessel called a Sea Fortress, and can combine their vessels into fleets with other players.
Isles of Abyss also adds an underwater layer, with sunken ruins to explore, aquatic resources to harvest and deep-sea creatures to hunt.
