Once Human is a free-to-play open-world survival game set in a post-apocalyptic world infected by an alien substance called Starchrom. You collect Deviations — mutated creatures that serve as combat companions and base utilities — while building territories, crafting gear, and fighting in both PvE and PvP content. The game operates on seasonal servers that reset periodically, with some progression carrying over through the Cradle system. With gunplay-focused combat, a distinctive art style blending sci-fi with cosmic horror, and the unique Deviation collection system, Once Human offers a fresh take on the survival genre.
Starting Once Human can feel overwhelming. This guide tells you exactly what to focus on during your first hours so you don't waste time on things that don't matter yet.
What Kind of Game Is This?
Once Human is a survival game built around deviation collection and territory building. The core loop involves mastering these systems to progress through increasingly challenging content.
What to expect: Time investment in learning mechanics, experimentation, and gradual mastery. The game rewards patience and knowledge.
Choosing Your First Build
| Build | Beginner Rating | Why |
|---|---|---|
| Firearm DPS | Good (but demanding) | Engage at medium range with automatic weapons, use cover, mod weapons for maximum DPS. |
| Melee Tank | Situational | Close distance quickly, tank damage with armor and Deviation support, deal heavy melee damage. |
| Support Build | Excellent for beginners | Deploy healing and buff Deviations during group content, support allies, handle secondary DPS. |
| Sniper | Excellent for beginners | Engage from maximum range, one-shot enemies with headshots, reposition between shots. |
| Deviation Master | Excellent for beginners | Deploy combat Deviations as primary damage, support with gunfire, collect rare Deviations. |
Our recommendation: Start with Melee Tank. Melee combat with heavy armor for close-range fighting. Melee is risky in a gun-focused game but deals high per-hit damage. Melee Tank requires Deviations that provide healing or damage absorption to survive closing distance.
Avoid Deviation Master as your first pick. Focus on maximizing Deviation collection and combat effectiveness.
First Session Step-by-Step
Step 1: Learn deviation collection
Deviations are mutated creatures you capture and deploy as combat pets, base utilities, or decorations. Some Deviations fight alongside you in combat, others generate resources at your base, and rare ones provide powerful passive buffs. Collecting Deviations is a core progression track alongside gear and levels.
This is the foundation. Spend your first 15-30 minutes getting comfortable with how deviation collection works before worrying about anything else.
Step 2: Head to Dayton Wetlands
The starting region with low-level enemies and abundant basic resources. The Wetlands introduce core mechanics in a safe environment. Your first territory should be established here.
Clear the main content here before moving on. Everything teaches fundamentals you'll need later.
Step 3: Get Your First Upgrade
Look for Shotgun — it's the most accessible early upgrade. Devastating at close range with spread pellets. The Shotgun is the best weapon for clearing tight spaces and fighting in buildings. Limited range means repositioning is essential.
Step 4: Understand territory building
Claim territory and build a base with walls, defenses, crafting stations, and Deviation deployments. Territory placement near resources saves travel time. PvP servers allow territory raiding, while PvE servers protect your base. Territory upgrades unlock better crafting and storage.
This is the system most new players overlook. Invest time here early — it pays off throughout the entire game.
Step 5: Push to Blackfell
A corrupted zone with Starchrom-infected enemies and environmental hazards. Blackfell enemies are tougher but drop better loot and Deviation materials. The corruption creates unique visual and gameplay elements.

seasonal resets
Servers operate on seasonal cycles — at season end, servers reset. Character progression transfers partially through the Cradle system (permanent account-level upgrades). Seasonal resets keep the experience fresh but require rebuilding each season.
Starchrom crafting
Starchrom-infused materials create the game's best equipment. Starchrom crafting requires rare materials from world events and high-level content. The crafting system follows standard survival game patterns (gather > process > craft) with Starchrom adding a unique tier.
world events
Dynamic world events spawn across the map, providing the best loot and Starchrom materials. Events range from alien invasions to corrupted zone purification. Participating in events with other players provides social gameplay and the best rewards.
Common Beginner Mistakes
1. Ignoring Deviation collection — Deviations provide combat power equivalent to weapon upgrades
Players who skip Deviation hunting miss significant power increases.
2. Building territory in poor locations — a base far from resources means constant travel time
Scout resource locations before placing your territory.
3. Not participating in world events — events provide the best loot in the game
Ignoring them means slower progression than active participants.
4. Investing heavily in gear before understanding seasonal resets — gear is temporary per season
Focus on Cradle upgrades for permanent progression.
5. Playing solo in group content — world events and dungeons are tuned for groups
Solo players receive worse rewards and face higher difficulty.

Tips for New Players
- Deviations are pets that give combat buffs — deploy combat Deviations before every fight for significant damage and survival bonuses.
- Seasonal servers reset, so transfer important progress through the Cradle system. Cradle upgrades are permanent across seasons.
- Territory placement near resources saves hours of travel time over a season. Scout locations before committing to a territory spot.
- World events give the best loot drops — participate in every event you encounter. Events scale with player count, so grouping up is advantageous.
- Cradle upgrades are permanent progression that persists across seasonal resets — prioritize Cradle investment over temporary gear.
- Weapon modding dramatically increases effectiveness — even a basic AK-47 with good mods outperforms a rare unmodded weapon.
- PvE servers protect your base from raiding — choose PvE unless you specifically want the PvP experience.
- Group content provides significantly better rewards than solo content — join a faction or group for world events and dungeons.
- Deviation enhancement materials are rare — only enhance your best combat and utility Deviations rather than spreading enhancements thin.
- The game is free-to-play with a battle pass — core gameplay is accessible without spending money. The battle pass provides cosmetics and convenience items.
Frequently Asked Questions
