Seasonal Scenario System

Once Human uses scenarios to provide different survival experiences.

Rather than presenting one completely static world, scenarios can introduce different objectives, rules, progression systems and environmental challenges.

This gives the game a seasonal structure while allowing players to experience different versions of its world.

Combat Gameplay

Combat combines ranged shooting, equipment management, character progression and tactical positioning.

You may encounter:

• Standard Deviants
• Elite enemies
• Large bosses
• Environmental threats
• PvP opponents
• Scenario-specific enemies

Successful combat often depends on preparation rather than simply shooting as quickly as possible.

Choose the Right Weapon

Different encounters favor different approaches.

Assault Weapons

Useful for flexible medium-range combat.

Sniper Rifles

Excellent for players who prefer precision and distance.

Close-Range Weapons

Useful when enemies get too close or when fighting inside buildings.

Special Weapons

Certain equipment can provide unique advantages against particular threats.

Experimenting with different loadouts is an important part of progression.

PvP and Competitive Survival

Once Human also provides opportunities for players who want competition against other survivors.

Depending on the scenario, players can encounter PvP systems alongside the game's cooperative survival elements.

This creates a different type of danger.

A resource-rich area may be dangerous not only because of Deviants, but also because another player wants the same resources.

Exploration Is Rewarding

The open world encourages players to look beyond the main objective.

You can discover:

• Hidden locations
• Resources
• Equipment
• Missions
• Strange creatures
• Environmental secrets
• Boss encounters
• Story clues

The scale of the map makes exploration feel like an important part of progression rather than simply transportation between quests.

Story and Mystery

The story revolves around the collapse of civilization and the mysterious Stardust phenomenon.

You are one of the few humans capable of surviving its effects.

As you progress, you begin to uncover information about what happened to the world and why Stardust changed everything.

The central question remains:

What does it really mean to remain human after the world has changed?

Beginner's Guide

1. Follow the Early Missions

The opening missions introduce important mechanics and help establish your initial progression.

2. Collect Everything Useful

Resources become increasingly important as you expand your base and craft better equipment.

3. Build a Functional Base

Prioritize storage and crafting before spending too many resources on decoration.

4. Experiment With Deviants

Don't ignore the companion system. Different Deviants can provide different benefits.

5. Upgrade Your Equipment

Better weapons and armor make exploration significantly safer.

6. Don't Fight Every Enemy

Sometimes avoiding an unnecessary fight saves ammunition and resources.

7. Play With Friends

Cooperative play can make difficult bosses and dangerous areas much easier.

Advanced Survival Tips

Prepare Before Long Expeditions

Carry enough supplies before traveling far from your base.

Don't Ignore Your Base

A well-organized territory makes crafting and resource management much easier.

Study Boss Patterns

Learning attack patterns can be more valuable than simply increasing your damage.

Use Cover

Positioning is especially important during ranged combat.

Build Around Your Playstyle

If you prefer combat, prioritize weapons and ammunition production. If you enjoy crafting, develop your resource and production systems.

Keep Exploring

The world contains more than the main storyline.

Base Building Tips

A practical base should have clearly defined areas.

Storage Area

Keep frequently used resources organized.

Crafting Area

Place important crafting facilities close together.

Living Area

Use bedrooms and decorative spaces to make your territory feel personal.

Production Area

Separate resource-processing equipment from your living space.

Defense

Consider traps and defensive equipment when building in dangerous environments.

Progression System

The core progression loop can be summarized as:

Explore → Gather → Craft → Build → Fight → Upgrade → Discover → Expand

You continuously improve your character, equipment and territory while exploring new scenarios and threats.

The scenario system also gives experienced players additional objectives beyond the basic survival loop.
