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 (12 with the Wild Wasteland trait). They are shaped like the "Fat Man" WWII atomic bomb. When they explode, they create a large blast resulting in a mushroom cloud. Also, the area where the mini nuke detonated has a temporary, decreasing radioactivity, counting down from 40 Rads/sec. It will eventually vanish, but will stay at low levels for quite a while, while the high radiation vanishes very quickly. Numerous mini nukes have been added in the Lonesome Road add-on as a random spawn chance in duffel bags and other containers.

Mini Nuke, low yield
A sub-type added with Gun Runners' Arsenal. This is considered the "light" version of your standard mini nuke as it packs less of a punch and the affected area is smaller, but has the benefit of an increased range.

Mini Nuke, big kid
A sub-type added with Gun Runners' Arsenal. This type deals significantly more damage than your standard Mini Nuke, and an increased explosion radius, at the cost of reduced range. WARNING: Decreased range plus the bigger blast radius can result in the player being seriously injured or even killed.

Mini Nuke, Tiny Tots
A sub-type added with Gun Runners' Arsenal. This type can be used for cluster bombing, each Tiny Tots fires a group of 9 miniature sized mini nukes, similar to the Experimental MIRV. When they start to descend, they make a noise similar to incoming artillery launched by the Boomers.

Mini Nuke, Timed
A sub-type added with the Gun Runners' Arsenal. This type has a fixed-length 5-second fuse, and can ricochet if it hits something before this time and can be bounced around corners. Direct impacts with the mini nuke may kill low health NPC's.

Weapons using this ammunition

 * Fat Man (GRA)
 * 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.
 * When using the Tiny Tots mini nuke in buildings it may cause the game to freeze in place.
