Aberrant particles stayed dormant in the nether, waiting for the call of the Great One and driving the world into madness; one day, scientists opened a gate … Following a New Weird style, Once Human combines the rationality in science with the mysteries of the unknown. In a precarious world where all common sense is distorted, will humanity fall into the abyss or thrive on adversity?

To survive in the wasteland, humans must unite in groups. With coldblooded research nuts, honest yet simple civilians, violent lunatics, optimistic dreamers and lone wolves, factions are formed. Among these factions, five attract the most attention: Rosetta, Blackfell, Vulture, Guerilla, and Mayfly.

Plant, animal and human infected by Stardust will transform into disfigured monsters called Aberrant. Once polluted by Stardust, the host will be swept along to join the evolution route of Stardust while the winner becomes an advanced organism and the failed ones decay to dust. In early state, Aberrants may not be too aggressive, but as time goes, they will be driven wholly by the desire to evolve and show their cruel nature.

With multiple weapon choices from handgun to submachine gun, players may excel in hardcore battles with their most handy firearm. What's more, your favorite gun actually grows with you! Use gun perk to make a killing machine out of your weapon. Use lethal weapons and unleash destructive skills to fight your way out. Battles can take place almost anywhere in Nalcott. With Aberrant, Rosetta and Vultures rampaging about, you are never short of enemies.

In the Stronghold Contest, Defender and Attacker battle to take control of the Beacon Area in the middle stronghold, and capture progress will accumulate when the area is free of the opposite team. Whoever seizes the area is the winner.

Various landscapes, realistic weather changes, and distinctive features. From desert to forest, Once Human offers a glimpse of the world taken over by nature and otherworldly creatures.

Starry Studio announced that Isles of Abyss, the massive Ocean Expansion for Once Human, will officially launch on October 22 (Oct 21 PT), 2026.

Available as a free update, the expansion will arrive simultaneously across PC, mobile, and consoles (PS5 and XBOX Series X/S), with full cross-play and cross-progression.

Marking the largest content update in Once Human’s history since its 2024 launch, Isles of Abyss expands the game’s Stardust polluted world into a vast, uncanny ocean - introducing entirely new survival mechanics, mobile naval fortresses, and 5 distinctive sea regions.

"The Sunken Lord" & Six Rules of Survival 

At the heart of Isles of Abyss lies a disturbing secret: the sea is not merely an environment, but an ancient, awakening entity known as "The Sunken Lord." Beneath the shrouded waters and distant lighthouses, something vast and hostile watches every surge of the tide - transforming the ocean itself into a living entity that hungers for those who dare to cross it.

As revealed in the recently released Release Date Reveal Trailer, Malla, an enigmatic navigator who has "drowned a thousand times," warns players of six critical rules from her logbook..These rules expose the ocean's lethal traps - from predatory lighthouses to disguised, living islands - —outlining the unique hazards players must overcome to survive. 

Conquer the Ocean: Custom Warships & Land-Sea Dual Survival 

Isles of Abyss expands Once Human’s gameplay into vast, uncharted waters through a brand-new experience:

• Unprecedented Freedom of Shipbuilding: Players can craft, customize, and upgrade their vessels from agile skiffs to massive Mobile Sea Fortresses. Transform your ship into a fully functional base, workshop, and heavy artillery platform. How players design their vessels directly dictates their tactical approach to oceanic hazards, encouraging creative problem-solving and adding immense gameplay depth.

Land-Sea Dual Survival Loop: Survival spans three seamlessly connected layers- navigating treacherous sea surfaces,            exploring mysterious islands, and diving deep underwater for buried treasures and aquatic resources. Each layer feeds directly back into core player progression, creating a rich, mutually sustaining survival economy between land and ocean. Navigate five distinct oceanic regions where the sea itself acts as a massive, hostile entity watching your every move.
