About Once Human

Once Human drops you into an unforgiving wilderness where survival hinges on managing hunger, water, and sanity. The world is tainted by Stardust, turning food and water into hazards that can lower your maximum health. The game blends combat, crafting, and base building while you uncover the mystery behind Stardust. Multiplayer modes let you cooperate or clash with others as you explore settlements, face dimensional bosses, and shape your own territory.

01 / THE GUIDE

Survival Mechanics

You awaken alone in a barren landscape, forced to contend with monsters and scarce resources. Food and water are often polluted, and consuming them reduces your Sanity, which in turn lowers your maximum HP. Balancing the need to eat and drink against the risk of sanity loss creates a constant tension, making every decision about sustenance critical to staying alive.

  • Prioritize finding clean water sources before venturing far.
  • Monitor Sanity closely; low Sanity can quickly diminish survivability.

02 / THE GUIDE

Combat & Bosses

Combat pits you against former humans turned monsters and powerful bosses from another dimension. Defeating these foes yields powerful items that help mitigate Stardust’s effects. The battles are designed to test your weapon choices and tactics, rewarding skillful play with gear that can turn the tide against increasingly dangerous enemies.

  • Study boss patterns before engaging to avoid unnecessary damage.
  • Use environmental cover to reduce exposure to enemy fire.

Weapon Customization

Around 100 gun blueprints across seven categories let you craft and modify firearms. Accessories and gun perks act as core enhancements, allowing deep personalization of each weapon. If a weapon feels lacking, you can attach new parts or perks, effectively upgrading its performance to suit your playstyle.

  • Experiment with different perk combinations for optimal damage.
  • Collect blueprints from varied sources to expand your arsenal.

04 / THE GUIDE

Territory Building

Using the Territory Core, you can construct a personal house, ranging from compact rooms to larger townhouses with patios, kitchens, and garages. The built area serves as a safe haven and storage for loot. Territories are relocatable, giving you flexibility to move your base as the world changes or as you discover better locations.

  • Place essential crafting stations near your entry point for quick access.
  • Relocate your territory when resources become scarce nearby.

05 / THE GUIDE

Factions & Story

Multiple factions populate the world, each with distinct attitudes ranging from hostile to helpful. Interacting with settlements reveals stories and clues about Stardust’s origin and purpose. Your choices—whether to aid survivors or simply eliminate threats—shape how factions respond and influence the unfolding narrative.

  • Engage with friendly factions to gain useful information.
  • Consider the long‑term impact of aggressive actions on future encounters.
