Once Human is an online action-survival game set in a wilderness altered by Stardust. Its threats include monsters and scarcity, but the environment itself matters too: polluted food and dirty water damage Sanity, and reduced Sanity lowers maximum health. That makes survival more than a matter of fighting what is in front of you.
Combat and preparation are closely linked. Players battle enemies that were once human and confront otherworldly bosses for powerful items, while collecting and crafting gun blueprints and tuning firearms with parts and perks. Between expeditions, a Territory Core lets players build a home, from a compact practical space to a more elaborate townhouse, and relocate it when desired. The search for Stardust’s origins also takes place among settlements and factions, which may be hostile or helpful.
Steam lists multiplayer, MMO, PvP, online PvP, co-op, and online co-op categories, while the game description presents combat, building, exploration, and faction encounters as parts of a shared world. Those elements help explain why people may come to Once Human for different kinds of play, without implying any particular population level or trend.
