Diving into Once Human can feel like stepping onto an alien planet where the rules of reality have been entirely rewritten. Starry Studio has crafted a unique blend of survival mechanics, weird-fiction horror, looter-shooter progression, and base-building. You are not just fighting off zombies; you are dealing with interdimensional anomalies, literal buses walking on spider legs, and a pervasive, invisible threat known as Stardust pollution.
The sheer volume of systems introduced in the first few hours is staggering. You have to monitor your hydration and hunger, build a secure territory, navigate a massive memetics tech tree, capture supernatural companions, and decipher a complex weapon blueprint system. It is very easy to make mistakes early on that will cost you hours of grinding later.
Many new players immediately try to treat Once Human like Rust or ARK, spending their first dozen hours chopping wood and building a massive fortress in the starting zone. Others treat it strictly like a shooter, ignoring the survival mechanics until they are starving, dehydrated, and rapidly losing their maximum health to pollution.
To thrive in the hostile environment of Nalcott, you need a balanced approach. This guide will walk you through the essential early-game strategies, common beginner pitfalls, and the most efficient ways to manage your resources. We will cover the critical Sanity system, smart base-building principles, how to leverage your Deviant companions for passive income, and how to navigate the murky waters of gear progression.
1. Managing Your Sanity
In Once Human, your Sanity acts as a hard cap on your maximum health. It is arguably the most important survival metric in the game. As your Sanity drops, a dark purple bar will creep across your health meter, reducing the total amount of HP you can have. If your Sanity hits zero, you are effectively a one-shot kill for most mid-tier enemies.
The Stardust Threat
Sanity is drained primarily by exposure to Stardust pollution. You will encounter pollution in two main ways:
- Environmental Pollution: Certain high-level zones, anomaly areas, and boss arenas are bathed in ambient Stardust. Just standing in these areas will slowly drain your Sanity.
- Consuming Contaminated Items: This is the most common beginner mistake. Eating raw meat, drinking unpurified water, or consuming certain scavenged foods will immediately chunk your Sanity.
How to Restore and Protect Sanity
- Boiled Water: Never, ever drink dirty water straight from a river or pond. Always build a stove or campfire and boil it first. Even better, rush the Memetics tree to unlock the Water Filter, which automates the process and provides pure water.
- Sanity Gummies: These are your best friend early on. Craft them at a stove using basic ingredients (like berries and sugar). They instantly restore a significant portion of your Sanity. Keep at least 10 in your quick-slot (usually bound to your D-pad or a number key) at all times, especially before entering a Monolith or a Rift Space.
- Resting: Sleeping in a bed at your base slowly regenerates both health and Sanity. If you are totally drained and out of resources, teleport home and take a nap.
Pro Tip: When exploring, keep an eye on your backpack icon in the bottom left of the UI. If it starts glowing purple, you have entered a polluted zone. If you don't have adequate gear or Sanity items, turn back immediately.
Mid-Game Mitigation
As you progress, you will unlock specialized gear and armor mods that provide passive Stardust resistance. The Hazmat suit, while offering poor ballistic protection, is essential for exploring highly polluted late-game zones where Sanity drain is otherwise unmanageable.
2. Smart Base Building
Base building is incredibly robust, but you should not overcommit to your first property. The map of Nalcott is absolutely massive, and resources are localized. If you build a sprawling mansion in the level 1-10 starting zone, you will spend half your playtime just driving your motorcycle back and forth across the continent to farm high-level materials.
The "Starter Box" Approach
For your first 15-20 levels, keep it compact.
- Build a 3x3 or 4x4 Starter Box: Use basic wood structures. You only need enough floor space for a bed, a stove, a basic crafting bench, a gear workbench, and a few storage crates.
- Verticality is Key: If you need more room, build a second floor rather than expanding the footprint. It saves on materials and makes defending your base during Purge events much easier.
- Territory Terminal: Place this terminal in the dead center of your base. Upgrading it expands your build radius and increases your structure limit. More importantly, it acts as your fast-travel anchor, allowing you to teleport home for free from any teleportation tower you have unlocked.
Relocating Your Base
One of the best features in Once Human is the base relocation system. You do not need to tear down your house piece by piece to move.
Pro Tip: Simply find a new, flat plot of land in a higher-level zone, open your build menu, and select the "Relocate Territory" option (usually the 'Z' key). The game will literally pick up your entire base—foundations, walls, chests, and crafting stations—and plop it down in the new location.
Always look to move your base near crucial resource nodes. Once you hit the mid-game, finding a spot near water (for passive water pumps) and near Copper or Iron ore veins is highly recommended.
3. Catching and Using Deviants
Deviants are the strange, supernatural anomalies you encounter throughout the world. Rather than just fighting them, you can capture certain Deviants and put them to work. They are split into two categories: Combat Deviants (which you take with you) and Territory Deviants (which stay at your base).
Combat Deviants
- The Butterfly (V) / Festering Gel: The Butterfly is usually the first Deviant you acquire. It is incredibly useful, acting as a recon drone that highlights enemies through walls and distracts them in combat. Alternatively, the Festering Gel is an excellent early-game choice as it provides a stationary healing field, saving you from burning through precious health activators.
- Upgrading: You can upgrade your Combat Deviants using securingment units at your base, feeding them Stardust Source to increase their power, duration, and cooldown recovery.
Territory Deviants: Automating the Grind
This is where the real power lies. Territory Deviants completely change the game's economy.
- Digby Boy: This little guy mines ore for you. Put a Digby Boy in a Securement Unit at your base, ensure its mood is high by providing it with optimal conditions (like specific lighting or temperature), and it will passively generate hundreds of Copper, Iron, and eventually Aluminum ore while you are offline.
- The Beaver (Buxom Woodcutter): Operates identically to Digby Boy, but for wood.
- Electric Eels: When placed near generators, they boost the power output of your base significantly.
Pro Tip: Always read the "Requirements" tab on a Deviant's Securement Unit interface. Some Deviants work faster when placed near a radio playing specific music, while others prefer red lighting or high temperatures. Meeting these conditions maximizes their resource gathering output.
4. Gear Progression and Weapon Blueprints
Once Human uses a blueprint system rather than traditional looter-shooter drops. While you will find weapons in crates out in the world, these weapons cannot be repaired. Once they break, they are gone forever. To get permanent gear, you need blueprints.
Understanding Blueprints
Blueprints are acquired by completing main story quests, finishing regional Mystical Crates (hidden in large POIs), or through the Wish Machine (a gacha-style system that uses Starchrom, an endgame currency).
- Crafting and Calibrating: Once you have a blueprint, you can craft the weapon at your gear workbench. More importantly, you can "Calibrate" it using weapon parts. Calibration acts as a leveling system for your guns, drastically increasing their base damage.
- Tier Progression: Do not waste rare materials calibrating Tier 1 or Tier 2 weapons to max level. Save your resources for Tier 3 and above.
Armor Sets and Synergies
Do not mix and match random pieces of armor. Armor sets provide massive set bonuses. Even a low-tier complete set is generally better than a mishmash of high-tier uncoordinated pieces.
- For early game, the Agent Set provides excellent critical hit bonuses.
- As you progress, look for sets that complement your weapon type. If you are using an LMG that relies on the "Burn" status effect, farm for blueprints that specifically enhance Burn damage and duration.
FAQ
How do I get a motorcycle? You unlock the motorcycle very early in the main questline after completing the initial tutorial zone and reaching the first major settlement (Deadsville). Make sure to craft fuel at your base using a Refining facility, as the bike will eventually run out of gas.
What happens to my base when I log off? Your base remains in the world, but it is generally safe from random mob attacks unless you have initiated a Territory Purge (a wave-defense mini-game). However, your Deviants will continue to work and gather resources while you are offline, provided their Securement Units have power and their mood is stable.
Can I respec my Memetics (Tech Tree)? Yes. You can reset individual nodes in your Memetics tree, but it costs a specific currency (Energy Links) to do so. It is relatively cheap early on, so don't stress too much about making the "wrong" choices in the first 20 levels.
How do seasons work? Once Human operates on a seasonal wipe schedule. At the end of a scenario (which lasts several weeks), your character level, map exploration, and physical base will wipe. However, you retain all of your Weapon Blueprints, Mods, Starchrom, and premium cosmetics for the next season.
