Once Human drops you into a vast 256 km² supernatural open-world where every river, volcano, swamp, and desert is yours to conquer. Harness the alien Stardust as a Meta-Human to craft, build, and battle through a seamless post-apocalyptic landscape packed with high-risk PvE and PvP action.

Meta-Human Power System
Absorb Stardust to unlock evolving combat abilities—elemental blasts, stealth mutations, or brute-force berserker modes—tailoring your survivor to any play-style.

Deviation Companion Sandbox
Tame over 50 quirky Deviation pals: a machine-gun alpaca for cover fire, a mini dragon chef for buff meals, or a tireless mining golem for rare ore. Feed, house, and level them to unlock combo-skills that turn the tide in raids.

Base-Building Without Limits
Erect multi-level fortresses anywhere—floating sky platforms, underwater bunkers, or volcano-side strongholds. Wire automated turrets, electric traps, and Stardust reactors to defend your loot 24/7.

Dynamic Faction Warfare
Join or create guilds to siege rival territories, capture Stardust anomalies, and control resource nodes. Weekly territory resets keep the end-game meta fresh for hardcore survival clans.

Co-op Raid & World Events
Team up in 8-player squads to hunt towering world bosses, clear contaminated labs, or race for airdrop caches. Shared loot tables and guild warehouses encourage tight-knit cooperation.

Seasonal Content Loop
New aberrations, weapon blueprints, and Deviation species arrive every season, pushing veterans to adapt builds and newcomers to jump straight into the action.
