Once Human is a free-to-play open-world survival crafting game on PC that blends action, strategy, RPG, simulation, and adventure elements in a post-apocalyptic setting twisted by alien influences.
Gameplay
In Once Human, you start in a vast, contaminated wilderness where survival hinges on managing resources and threats. Gathering materials involves basic actions like punching trees or mining, with resources that regenerate quickly. As you progress, Memetic upgrades unlock automated tools such as mining devices and rainfall catchers to streamline collection.
Combat focuses on battling mutated enemies and bosses from other dimensions, using customizable weapons. There are over 100 gun blueprints across seven categories, which you can enhance with accessories and perks. Melee options include blades and bats, while ranged weapons cover pistols, rifles, and shotguns. A key mechanic is the Sanity system: consuming polluted food or water lowers your Sanity, reducing maximum HP.
Building plays a central role, letting you use a Territory Core to construct and relocate homes or larger structures. Deviations, which are capturable alien creatures, assist in fights or handle base tasks like ore gathering. The core loop revolves around exploring a huge map divided by enemy levels, activating Rift Anchors, and upgrading gear through crafting and ownership rules where player-made items can be repaired indefinitely.
Game Modes
Once Human operates through themed servers called Scenarios, each offering distinct PvE or PvP experiences. Manibus is a PvE-focused scenario where players team up for server-wide quests like Prime Wars and tackle overworld bosses. It includes optional PvP in events such as Cargo Scramble.
Evolution's Call emphasizes PvP, with players toggling Chaos State to engage in combat over resources, including territory wars and echo stone purifications. Prismverse's Clash introduces faction-based PvP between groups like Mayflies and Rosetta, set in war zones across a phased 19-day structure.
Other scenarios include Way of Winter for harsh environmental survival, Endless Dream for confronting dream zones, and Deviation SCP, where you capture and battle with Deviants. Eternaland provides a private, wipe-free mode dedicated to building. Instanced dungeons support up to four players, often formed via a server-wide team finder.
Updates and Seasons
Once Human follows a seasonal model, with each season typically lasting six weeks before a server wipe, though progress like blueprints and quest advancements carries over. At a season's end, servers enter a Settlement Phase, unlocking all content briefly before closure, and characters move to Eternaland.
As of early 2026, ongoing scenarios include Manibus and Evolution's Call in normal and hard modes, featuring enhancements like super anomalies and shiny Deviations. Newer additions like Deviation SCP, released in late 2025, focus on Deviant handling and matchmaking battles. The game has seen regular updates, including Season 3: Aberrant Progeny, expanding story and mechanics.
Is It Worth Playing?
With a Mostly Positive rating on Steam from 166,796 reviews (79% positive) and an 8/10 score from IGN, Once Human appeals to those who enjoy accessible survival crafting without overwhelming complexity. Players praise the deep building options and creature collection, though some note a steep difficulty curve in later areas.
If you like cooperative exploration, customizable gear, and seasonal resets that keep things fresh, this game fits well for groups or solo runs. It's free to play, making it easy to try, especially with ongoing support through new scenarios and events. However, if basic combat or repetitive quests turn you off, it might not hold long-term interest.
