Mini Nuke (Fallout: New Vegas)

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

Characteristics
Compared to Fallout 3, mini nukes are much less common in Fallout: New Vegas and weigh 3 pounds each in Hardcore mode. There are only a total of 14 in the base game. They are shaped like the "Fat Man" WWII atomic bomb, and when they are launched the explosion they create has a large blast radius, shaped like a mushroom cloud. Also, the area in which the mini nuke detonated has a temporary and decreasing radiation from the blast, counting down from 40 Rads/sec. It will eventually vanish, but will stay at low levels for quite a while, while the high radiation will vanish almost instantly. Numerous have been added in the Lonesome Road add-on.

Mini Nuke, low yield
A sub-type to be added with Gun Runners' Arsenal. This type of Mini Nuke will be considered the "light" version of your standard Mini-Nuke, this could possibly mean that it's lighter in hardcore, packs less of a punch, and the AoE could be downsized.

Mini Nuke, big kid
A sub-type to be added with Gun Runners' Arsenal. This type of Mini Nuke will deal significantly more damage than your standard Mini Nuke, at the cost of reduced range, and presumably, heavier ammunition.

Mini Nuke, Tiny Tots
A sub-type to be added with Gun Runners' Arsenal. This type of Mini Nuke can be used for cluster bombing, each Tiny Tots fires a tandem of 10, miniature sized Mini Nukes.

Weapons using this ammunition

 * Fat Man
 * Esther

Bugs

 * There is a glitch where sometimes if you kill an enemy and equip the Fat Man, then go pick up the dead enemy's gun, the ammunition from the gun will be converted into mini nukes and will remain in your inventory. This can also be done with the alien blaster and almost if not all other ranged weapons.
