Once Human PS5 Isles of Abyss Expansion Launch [Confirmed]

Once Human officially launches its massive free Isles of Abyss expansion on PlayStation 5 on October 22, 2026, delivering five brand-new open-water territories, naval base navigation, and terrifying cosmic anomalies to console survival players worldwide. According to verified reports from PlayStation Blog, the update plunges the post-apocalyptic survival sandbox into uncharted maritime waters where the ocean itself manifests as a living, hostile entity known as The Sunken Lord. Lighthouses dubbed The Tower and drifting ghost ships named Voyagers act as dark extensions of this cosmic force, transforming oceanic exploration into a relentless environmental gauntlet. Players must craft custom sea vessels, calibrate deep-water diving gear, and harvest pristine aquatic resources to withstand extreme weather patterns and aquatic Stardust mutants. Much like recent cosmic horror designs highlighted in our [Saros Boss Reveal: Overlords of Carcosa Details [Confirmed]](/news/saros-overlords-carcosa-boss-design), Once Human leans heavily into surreal psychological dread. Console players receive dedicated DualSense haptic feedback support for naval handling and trigger resistance during naval combat. This launch marks Starry Studio's most ambitious post-launch console milestone, bridging PC and console parity while expanding endgame cooperative raid encounters.
