Overview
Once Human features a diverse weapon system with five categories: Pistols, SMGs, Rifles, Shotguns, and Melee. Each weapon has a base type, rarity (Common to Legendary), level requirement, damage stats, and mod slots. The weapon mod system is where Once Human truly differentiates itself — you can customize every weapon with up to 4 mods that drastically change its performance.
| Weapon Type | Damage | Fire Rate | Range | Best For |
|---|---|---|---|---|
| Pistol | Medium | Medium | Short | Backup, early game |
| SMG | Low | High | Short | CQC, mob clearing |
| Rifle | High | Medium | Long | All-around, boss damage |
| Shotgun | Very High (close) | Low | Very Short | CQC, burst damage |
| Melee | Variable | N/A | Melee | Stealth, resource saving |
Weapon rarity tiers: Common (gray) → Uncommon (green) → Rare (blue) → Epic (purple) → Legendary (orange). Higher rarity means more base damage, more mod slots, and better stat rolls. Legendary weapons have 4 mod slots and unique passive effects.
Getting Started
The weapon mod system is the key to maximizing your damage output in Once Human. Every weapon has 1-4 mod slots (depending on rarity) that can be fitted with various mods. Mods are crafted at the Workbench or found as loot from bosses and world events.

Character builds in Once Human are defined by your Mimic Point allocation across three skill trees: Survival, Combat, and Gathering. While you can eventually max all three, your early and mid-game allocation defines your playstyle. Here are three proven builds:
Build 1: The Survivor (Recommended for Beginners)
A balanced build focused on survivability and versatility. Best for solo players and PvE.
Build 2: The Combatant (DPS Focus)
A high-damage build for players who want to maximize boss damage and PvP performance. Best for team play.
Build 3: The Gatherer (Economy Focus)
A gathering-focused build for players who want to maximize resource income and crafting efficiency. Best for players who enjoy the economy/crafting side.
Pro Tips & Common Mistakes
✅ Pro Tips
- Always mod your weapons — even common mods give +10% damage, and there's no reason not to use them.
- Match your elemental mod to the boss's weakness — it deals 50% more damage than a non-matching element.
- Craft weapons of the same set — 4-piece set bonuses (like Rustic: +move speed, +melee DMG, +max HP) are powerful.
- Keep a backup weapon with different elemental damage — some enemies resist certain elements.
- Repair your weapons before they break — a broken weapon deals 10% damage and can't be fired.
⚠️ Avoid These Mistakes
- Don't use the same weapon for every situation — swap to a shotgun for CQC and a rifle for ranged.
- Don't waste Legendary mods on Common weapons — save them for Epic/Legendary bases.
- Don't neglect armor — a full set of tier-2 armor reduces incoming damage by 40%, more than any Survival skill.
- Don't forget to reload between fights — getting caught with an empty magazine during a boss enrage is fatal.
- Don't spread your Mimic Points evenly across all three trees early — focus on one primary tree first.
Frequently Asked Questions
What are the best weapons in Once Human? +
The best weapons depend on your build and playstyle, but the current meta (Season 5) favors: For PvE boss damage, the Legendary Assault Rifle 'Void Reaper' with Damage + Crit + Armor Piercing + Elemental mods deals the highest sustained DPS. For mob clearing and CQC, the Epic SMG 'Storm Caller' with Fire Rate + Magazine + Damage + Reload mods is unmatched. For PvP, the Legendary Shotgun 'Crimson Breaker' with Damage + Crit + Magazine + Reload mods one-shots most players at close range. For beginners, any Rare Rifle with basic Damage and Crit mods will carry you through early and mid-game content. Always prioritize weapon type over rarity — a well-modded Rare weapon outperforms an unmodded Legendary.
How does the weapon mod system work? +
Weapons in Once Human have 1-4 mod slots depending on rarity (Common=1, Uncommon=2, Rare=3, Epic/Legendary=4). Mods are crafted at the Workbench or looted from bosses/world events. To install a mod, open your inventory, select the weapon, and click 'Mod Slots'. Drag a compatible mod into an empty slot. Mods can be removed and reused (they're not consumed on installation), so feel free to experiment. Each mod type has multiple rarity tiers — a Legendary Damage Mod gives +25% damage vs +10% for Common. The optimal strategy is to fill all 4 slots with the best mods you have, prioritizing Damage and Crit for DPS builds, or Fire Rate and Magazine for mob-clearing builds.
