As a seasoned survivor roaming the stardust-ravaged landscapes of Once Human, I’ve learned one brutal truth: without bullets, even the fanciest rifle is just a glorified club. The gunplay feels spectacular, but running dry in the middle of a Devourer fight teaches you fast that preparation is everything. In 2026, the game’s crafting mechanics have been refined, yet the core loop of turning raw ore and monster loot into stacks of gleaming ammunition remains your ticket to survival. Let’s break down exactly how I keep my arsenal fed, from early-game copper rounds to advanced logistics.

The backbone of any ammo production chain is the Supplies Workbench. I still remember the panic when I couldn’t find it in my first hour. You unlock this crucial station by snagging the Essential Tools upgrade from the Crafting Memetic tree. Without it, you’re stuck relying on melee and the slowly recoverable crossbow bolts. Speaking of which, crossbows are a fantastic stealth tool early on—you can actually pick your arrows back up, which saves resources while you farm for that first big ammo batch.

🧪 The Core Recipe: Copper Ammo

Once the bench is built, you need the Advanced Ammunition I memetic upgrade to craft gunpowder and copper ammunition. Copper rounds form the baseline for all bullet types, and the recipe is beautifully simple:

  • 1 Gunpowder

  • 3 Copper Ingots

This ratio never changes, whether you’re cranking out pistol rounds or rifle cartridges. Bulk crafting is your friend; the materials are light enough to hoard hundreds of rounds without crippling your carry weight. I routinely leave my territory with at least 600 shots.

⛏️ Gathering Copper: Follow the Orange

Copper ore hides in plain sight. Look for regular boulders that have vibrant orange veins streaking across their surface. Mining them also requires the Smithing Essentials upgrade from the Infrastructure memetic tree, which gives you a furnace. That furnace is a workhorse—it smelts your raw copper into ingots and burns logs into charcoal simultaneously. When I’m playing with friends, we split up to cover high-density rock zones; it makes the chore feel less like a grind and more like a competitive treasure hunt.

🔥 Gunpowder: The Tricky Ingredient

Gunpowder separates the organised survivors from the desperate ones. The recipe is:

  • 6 Sulfur

  • 3 Charcoal

  • 3 Acid

Charcoal is a byproduct of your furnace, so always keep logs burning. Sulfur, on the other hand, comes from distinct yellowish rocks—shorter and wider than copper deposits, with their tops almost painted in mustard. The real bottleneck, though, is acid.

🧟 Farming Acid Efficiently

Acid drops from nearly every enemy you kill, but wandering the open world hoping for scraps is inefficient. My approach: pick an abandoned structure loaded with basic Deviants, equip a crossbow, and go full ghost. Silent takedowns mean I can reclaim my arrows as I work through the building. The enemies here respawn rapidly, turning the area into a renewable acid farm. In 2026, some camps have even seen tuned respawn timers, making it easier than ever to loop a single building for 80+ acid per hour without ever firing a crafted bullet. It’s boring, but it beats starving your main weapon.

🏭 Scaled Production and Advanced Tips

Once you’ve stockpiled the basics, efficiency becomes key. I set up multiple furnaces to parallel-process charcoal and ingots. A single farming session can yield enough sulfur and copper to produce over 1,200 rounds of copper ammo. The Supplies Workbench also supports queue crafting, so I start a batch, go tend my garden, and come back to a bag full of firepower. Remember, ammo weight is trivial, so there’s no reason not to craft until your resources run out.

❓ Common Ammo Questions

Question Answer
Can I craft special ammo types early? Not without advancing further in the Memetic tree; copper is your starter.
Is acid used for anything else? Yes, it’s also crucial for gunpowder, some medical items, and territory upgrades, so always farm surplus.
What if I can’t find sulfur? Try rocky areas away from water; sulfur nodes often blend with stone but have that unmistakable yellow cap.

One last piece of advice: don’t neglect your crossbow. Even with a mountain of copper ammo, the ability to silently pick off enemies and collect your projectiles again is invaluable for conserving acid in the long run. As the game continues to evolve in 2026, with new weapon tiers and stardust-infused horrors lurking around every corner, a bullet-savvy survivor will always have the upper hand. Now get out there, mine some orange rocks, and turn that acid into a symphony of gunfire.
