Once Human is a multiplayer open-world survival game taking place in a bizarre, post-apocalyptic future. Team up with friends to battle terrifying foes, reveal hidden conspiracies, battle for supplies, and establish your own domain. Once, you were just human. Now, you hold the power to reshape the world.
Discovered by the research collective Rosetta, "Stardust" is far from a typical material. It is deeply entwined with a series of bizarre events that challenge understanding. Initially celebrated as a breakthrough for technological progress, Rosetta's experiments with stardust eventually led to "Starfall"—a cataclysm in which the Great Ones erupted from Rosetta's experimental monolith, scattering stardust across the land. This unleashed a cascade of disturbances: from genetic transformations to societal chaos and the sudden downfall of human civilization. Yet, among those exposed to stardust, a rare few did not succumb to madness or mutation. Instead, they gained extraordinary powers and became known as "Metas." These individuals soon became vital in the fight against stardust and the effort to rebuild society. However, as beliefs diverged, the "Metas" fractured into distinct groups. Some, embracing Rosetta’s vision of endless evolution through the absorption of deviant energy, chose to remain loyal to Rosetta and are now called the "Evolutionists." Others revere the Great One and abandon Rosetta in hopes of welcoming the return of the Great One’s rulers, forming the "Ascendants." And then there are those who seek a new way forward—one that coexists with the deviations and deviants. You are among them, part of an organization known as the "Mayfly." In a world overrun by deviations, a new order awaits your creation.
