Frequently Asked Questions
How many rounds per zombie?
It depends on weapon: sniper ~1.5, shotgun ~2.0, rifle ~2.5, pistol/SMG ~4.5–6.0. These account for misses and body shots on standard zombies.
Does the Ammo Factory perk reduce materials?
Yes - rank 1 reduces crafting materials by 10%. We apply this automatically when you check the perk option.
Why is forge time listed?
Most ammo components (brass casings, lead bullets) must be crafted in a forge. Forge time helps you plan ahead - allow several in-game hours before horde night.
