The mini nuke is a type of ammunition in Fallout: New Vegas.


Mini nukes are much less common in Fallout: New Vegas than in Fallout 3: there are only 14 in the base game (12 with the Wild Wasteland trait). They weigh 3 pounds each in Hardcore mode and are shaped like the WWII atomic bomb, the "Fat Man." Their explosion is powerful, causing a characteristic mushroom cloud and leaving residual radioactivity, initially 40 rads/second, but which quickly drops to low levels that linger for quite a while.

The Lonesome Road add-on introduces the possibility of mini nukes randomly spawning in duffle bags and other containers. Due to their rarity and effectiveness, mini nukes are the most valuable ammunition type in-game.

Weapons using this ammunition[]


  • Gun Runners' Arsenal Mini nuke, low yield - This variant has less explosive power and a smaller kill radius than a standard mini nuke, but with the trade-off of increased range and cheaper price.
  • Gun Runners' Arsenal Mini nuke, Big Kid - This variant is significantly more powerful than a standard mini nuke and produces more residual radiation. The increased damage comes at the cost of reduced range, which can cause serious harm to an unprotected individual.
  • Gun Runners' Arsenal Mini nuke, Tiny Tots - This type can be used for cluster bombing, with each tiny tots round releasing 9 miniature mini nukes, similar to an experimental MIRV shot. While descending, they make a noise similar to incoming Boomer artillery.
  • Gun Runners' Arsenal Mini nuke, timed - This type has a 5-second fuse and will not detonate on impact. The time-only fuse allows the round to ricochet off objects or be bounced around corners. The nuke itself can also cause damage if it strikes a target, in addition to the following explosion.
