Isles of Abyss is a free oceanic scenario expansion for Once Human. Following a shipwreck, players navigate an archipelago that spans tropical coasts, tundra reefs, toxic marshes, and volcanic islands. Exploration relies on building ships, diving for deep-sea treasures, harvesting specialized marine resources, and contending with severe weather anomalies known as Haywire Zones.
The narrative centers on lost memories of drowned ships and introduces key companions Malla and Ran. Progression unfolds across server-wide purification milestones, culminating in a frontline confrontation with an endgame threat known as the Sunken Lord.
