Not to be confused with Ammunition (Resource)


All Firearms need ammunition (ammo) to function. Different weapons require specific types of ammo. These types are usually referred to by their caliber (diameter of projectile), with some calibers being measured in inches (like .50 Cal rounds) and others in millimeters (like 9mm rounds).

Finding AmmunitionEdit


  • In Storyline and Breakdown modes, Ammo cannot be manufactured. It can be scavenged from Gun Shops, Police Stations, Military Stashes and civilian houses. In Lifeline, it can be produced at the Ammunition Shop. The Year One Survival edition adds Munitions shop to both Storyline and Breakdown modes.
  • Some enclaves' supply lockers can contain ammo.
  • Breaking open an Ammo Crate found in containers can also spawn ammo.

Restocked LockerEdit

  • In the original State of Decay, at the beginning of a new (real time) day, depending on the amount of Ammo (Resource) that the player has, the Supply Locker will be refilled with 30, 60 or 90 rounds for each non-rare type of ammo (i.e every type except .50 Cal and Grenade Launcher Ammo).
  • In Breakdown, this feature is not available. Enclaves' supply lockers, however, seem to restock ammo each day.

Ammunition UsageEdit

  • A clean headshot with any caliber will kill a normal zombie. Thus, it is recommended that the player sticks to the weaker rounds and only use more powerful rounds for targets like Juggernauts or Ferals.
  • Many firearms share the same ammo, so it is wise to choose the most accurate, powerful and/or quiet gun to get the most out of each shot. At the very least, choosing a quieter weapon is preferrable.


  • Most ammo cost 1 Influence per round, except .50 Cal (which cost 2) and Grenade Launcher Ammo (which cost 3).
  • In previous versions of the game, the original State of Decay, daily reset replaced the ammo in Supply Locker with 30,60 and 90 rounds instead of adding them. In addition, all stacks of ammo exceeding 60 rounds in the Suppy Locker was reduced to 60 each time the player loads a save file. This has since been patched.
  • Due to memory limitation and game balancing, many types of ammo of similar calibers in real life are grouped into one. For example, the 7.62mm round in the game represents many different calibers such as .30-06, .300 Win Mag, 7.62x39mm and .308 Winchester or 7.62x51mm NATO. This is pointed out in the description for the 7.62mm and 5.56mm, noting that they represent "caliber families".

    • does anyone know if having more guns in your supply requires more ammo resources?
    • it's based on the number of survivors in your camp.
