Field guide · Armageddon 1.0

Firearms & Ammo: ADS, Caliber and Armor

Apply official 1.0 firearm principles: deliberate opening shots, caliber-based penetration, scarce ammo and suppressor utility.

Quick answer

Aim down sights for opening shots, use caliber and distance deliberately, and pair firearms with melee because ammunition is heavier and intentionally scarce.

Operational sequence

What to do in a live run

  1. 01Step 1

    Take the first shot in ADS when you can

    The official firearm model gives ADS and opening shots the best accuracy condition. Create a deliberate first shot, then decide whether the next threat still justifies spending ammunition.

    Official notesS1
  2. 02Step 2

    Match caliber to the problem

    Caliber affects penetration, recoil and intended engagement. .308 is presented as a higher-penetration, higher-recoil option, while .22 LR emphasizes low recoil and close-range control at lower damage.

  3. 03Step 3

    Protect the ammunition economy with melee

    Ammunition is intentionally weighty and scarce. Use firearms for threats or lines that melee cannot solve safely, and switch before panic fire empties the reserve.

  4. 04Step 4

    On Nightmare, inspect found weapons

    Nightmare scarcity leans more on unloading weapons found in the world. Add that check to the team’s looting habit, but do not claim a fixed magazine amount where the game does not publish one.

    Official notesS2

Brief 01

Accuracy starts with the first shot

ADS significantly improves every gun, and the opening shots receive the ideal accuracy window. Hip fire is unreliable for most ammunition; in a desperate close fight, crouching or switching to melee can be safer than spraying.

Official notes + field adviceS1

Brief 02

Caliber changes the job

The official model ties penetration to caliber. A bullet that meets the armor threshold can continue with reduced damage. .308 emphasizes recoil and penetration; .22 LR emphasizes low recoil and close-range control at lower damage.

Official notesS1

Brief 03

Attachments and ammunition economy

Suppressors reduce zombie perception, while sights improve follow-up shots. Ammunition is heavier and intended to feel consequential, so save it for threats and lines that melee cannot solve safely.

Official notes + field adviceS1

Brief 04

Difficulty changes found ammunition

Armageddon allows spawned firearms to contain varying ammunition amounts based on difficulty. Nightmare scarcity specifically leans more on unloading weapons you find. This describes ammunition availability, not a hidden per-difficulty firearm damage modifier.

Brief 05

Current firearm data

Current game material documents caliber, penetration, recoil direction, ADS, suppressors and sights. Per-weapon damage, capacity, recoil and range can be added when a complete current dataset becomes available.

Field adviceS1S2

Before commitment

Run checklist

  • Start deliberate engagements in ADS.
  • Match caliber to armor and distance.
  • Unload found weapons when Nightmare ammo is scarce.
  • Switch to melee before panic fire empties the reserve.

FAQ / practical answers

Questions players ask before the next run

Should I ADS for every firearm engagement?

When time and space allow, ADS is the documented accuracy advantage, especially for opening shots. In a close emergency, create space or change tools rather than treating hip fire as a precision solution.

How does caliber affect penetration?

The official model ties penetration to caliber. A round that meets the armor threshold can continue through with reduced damage.

What do suppressors do?

They reduce zombie perception. Their value is managing attention and pressure, not a published universal damage increase.

Does difficulty change firearm damage?

This guide has no official evidence for a per-difficulty firearm damage modifier. Armageddon documents varying ammunition in found firearms by difficulty instead.

Where are exact gun damage, capacity and range values?

This page does not invent a complete per-weapon dataset. It will add those values only when a current, complete and traceable source is available.
