What Is Once Human?
Once Human is a free-to-play, third-person open-world survival shooter developed by Starry Studio, a NetEase subsidiary. It's set on a version of Earth ravaged by an extraterrestrial contamination called Stardust, which has twisted the landscape, mutated wildlife, and spawned reality-bending anomalies known as Deviants. It launched on Windows via Steam on July 9, 2024, followed by iOS and Android versions on April 23, 2025, and PlayStation 5 and Xbox Series X/S releases on August 25, 2026 — making it fully cross-platform across PC, console, and mobile.
Why Is Once Human So Popular?
Once Human broke into Steam's most-played chart almost immediately, peaking at more than 230,000 concurrent players in its first weeks and landing among the top ten most-played games on the platform at the time. That launch surge came from a combination that few survival games attempt: a shooter-grade gunplay loop, a genuinely unsettling supernatural setting instead of another zombie wasteland, and a generous free-to-play model that let people jump in without a purchase barrier. Player numbers have settled well below that peak years on — typical for any live-service survival title — but the game still pulls a steady daily population, and its seasonal update cadence keeps giving existing players a reason to come back.
Once Human Gameplay
The moment-to-moment gameplay leans closer to a looter-shooter than a pure survival-crafting game: firearms, weapon mods, and gear-rarity tiers sit alongside the genre's usual resource gathering, crafting, and base management. Combat blends ranged gunplay with power-based abilities gained from equipping "Deviants" — captured anomalous creatures that grant combat or utility skills. Progression runs through a mix of PvE questing and territory control, with dedicated server types for players who want PvP base-raiding and others that keep things purely cooperative.
Main Features of Once Human
- Shooter-first combat. Guns, mods, and gear rarity drive build variety more than melee or crafting-heavy survival mechanics do.
- Base building with real stakes. Fortified compounds with functional machinery and defenses matter for both PvE progression and PvP servers, where other players' bases can be raided.
- Deviant system. Capturing and equipping mutated creatures grants unique combat and traversal abilities instead of relying purely on weapons.
- Seasonal Scenarios. Each season resets progression on wipe servers for players who want a clean race, alongside persistent server options for those who'd rather not restart.
- Cross-platform live service. PC, PlayStation, Xbox, and mobile versions share the same content cadence and account progression.
- Cosmetic-driven monetization. Battle passes, outfits, and a gacha-style pull system for cosmetic weapon skins, rather than pay-to-win gear.
Once Human Open World
The map is split into distinct regions layered with the Stardust contamination's visual signature — twisted architecture, corrupted weather, and pockets of anomalous terrain that behave differently from the surrounding wasteland. Survival pressure comes less from classic hunger-and-thirst grinding and more from radiation zones, hostile factions, and world bosses that force players to gear up before pushing into new territory. Each seasonal Scenario (sometimes called a Deviation) has historically introduced new zones — 2026's season brought a multi-island, ocean-themed map with its own creatures and hazards — and wipe servers reset player progress and bases at the start of each season, while designated "Eternaland" or persistent-style servers let players keep long-term builds without restarting.
Once Human PC Requirements
| Minimum | Recommended | |
|---|---|---|
| OS | Windows 10 64-bit | Windows 10 64-bit |
| CPU | Intel Core i5-4460 | Intel Core i7-7700 |
| RAM | 8 GB | 16 GB |
| GPU | GeForce GTX 750 Ti / Radeon R9 270 | GeForce GTX 1060 / Radeon RX 580 |
| Storage | 60 GB | 70 GB |
The minimum bar is unusually low for a modern open-world shooter — a decade-old GPU and 8 GB of RAM will technically run it — but the recommended tier is where the game actually looks and performs the way it's meant to, so budget for an SSD with at least 70 GB free either way.
How to Download Once Human on PC
Once Human is available on Steam and through Starry Studio's official launcher. Install from either source, then sign in with your NetEase or linked account — progress and purchases follow your account rather than the storefront, which matters if you also play on console or mobile and want cross-progression. Stick to Steam or the official site for downloads; avoid third-party installers for a live-service game that handles account data and payments.
Is Once Human Free to Play?
Yes, on every platform. There's no purchase required to play, and none of the core survival, building, or PvP systems sit behind a paywall. Spending goes toward battle passes, cosmetic outfits, and a gacha-style pull system for weapon skins and character appearance items. It's generally regarded as not pay-to-win — gear and Deviants are earned through play — though, as with most live-service seasonal games, cosmetic FOMO and battle-pass timers are the real pressure points if you want to keep up with every season's look.
Is Once Human Worth Playing?
Reception has been mixed-to-positive rather than universally acclaimed. Metacritic's critic average sits in the mid-70s based on a modest sample of reviews, while Steam's overall user rating is "Mostly Positive" across a large review base, with recent review trends skewing noticeably more positive than the game's launch-era average — a sign that early technical issues and monetization complaints have eased as Starry Studio has patched and adjusted the game over multiple seasons. What reviewers consistently praise: the bizarre, Stardust-warped world, distinctive monster design, and genuinely satisfying gunplay for the genre. What holds it back for some: launch-period server and performance issues, and a seasonal wipe structure that some survival fans find frustrating.
Play it if you want a survival game built around real gunplay rather than crafting-heavy combat, you're drawn to its unsettling sci-fi setting over yet another zombie apocalypse, and you don't mind seasonal resets refreshing the map and progression. Skip it if you want a single persistent save you never lose, or you're allergic to live-service monetization layered onto a free base game — even a relatively fair one.
