For an overview of mini nuke ammunition types in the Fallout series of games, see mini nuke.

The mini nuke or micro-nuke[1] is a football-sized tactical nuclear warhead designed for use in a nuclear catapult weapon in Fallout 3.


Mini nukes are the most expensive type of ammunition due to their rarity, ranging from 250 to 400 caps each, depending on the player character's Barter skill. They are the ammunition for the two most powerful weapons in the game: the Fat Man and the experimental MIRV, doing many times more damage than any other weapon even with a low Big Guns skill. The explosion when fired is powerful, causing a characteristic mushroom cloud and leaving residual radioactivity. The users themselves may absorb radiation if they are close to the projectile even after detonation.

Weapons using this ammunitionEdit


There are a total of 70 free mini nukes in Fallout 3. Two more can be obtained by doing various quests. Another two are in random encounters, one of which only occurs after completing the Reilly's Rangers quest. Another can be found in Operation: Anchorage, 13 in Broken Steel, eight in Point Lookout and two in Mothership Zeta, making for 98 in total with all add-ons.

  • One way of obtaining mini nukes is to kill super mutant overlords which are found throughout the Capital Wasteland. Super mutant overlords can only be found with Broken Steel installed. Although they will not always have a mini nuke in their inventory, there is a good chance that they have one and can have up to three.
  • Flak 'N Shrapnel's in Rivet City frequently restock with mini nukes, to the extent that one can acquire up to five of them with every three in-game days.



  1. Lucky Harith calls them this when gifting one to you for upgrading his caravan
