Once Human is a free-to-play open-world survival game with an eerie, contaminated soul. This hub covers what it is, how it plays, and why players keep logging in past midnight.

Survival with atmosphere

Explore a huge post-apocalyptic map, loot and craft, build and defend a base, and fight mutated horrors solo or with a squad. The systems are solid — but it's the sci-fi horror mood that sets it apart from the survival pack.
