Fat Man (Fallout: New Vegas)

The Fat Man is a weapon in Fallout: New Vegas.

Characteristics
The tactical nuclear catapult returns in Fallout: New Vegas. It has the same appearance as the one in Fallout 3, though unlike its predecessor, its effectiveness is governed by the user's Explosives skill, rather than Big Guns.

Mods

 * Fat Man Little Boy kit - Decreases its weight by half (30 lbs. to 15 lbs.)

Locations

 * A Fat Man can be found on a dead body in Cottonwood Crater. Cottonwood crater can be found at the south of the map on top of a mountain at X-15.5 Y-1 (counting colored ticks, not individual ones), to the east of Searchlight Airport. When coming for the airport, you have to make your way around the mountain a little in order to get up to the top.
 * There is also another one with a Mini Nuke in the Quarry Junction (in a radioactive puddle of water), though it is guarded by a lot of deathclaws, including a mother and the alpha male.
 * Another is located in Nopah Cave on the dead body of a super mutant master. The cave contains fire geckos which can swarm you and do a lot of fire damage.
 * A Fat Man can be bought from the Brotherhood Armory in Hidden Valley after you are granted full access.
 * A Fat Man and 3 mini nukes can be pick pocketed from a Boomer while they are sleeping in a one of 3 tents to the southeast of the Mess Hall & Munitions Storage at Nellis Air Force Base.
 * A Fat man can be bought (randomly?) from the Boomer Munitions Manager in the Mess Hall & Munitions Storage at Nellis Air Force Base. The player first needs Pearl's permission to trade with him by gaining fame with the boomers.
 * A Fat Man can be found on the body of a super mutant master near a Cazador Nest directly south of Jacobstown. You go here to gather Cazador-eggs during the quest Bleed Me Dry. The area is accesible by going west from Red Rock Canyon, over some very steep trails (the player might need to do some tricky jumping on the rocks in the side of the trail to get up the initial slope).
 * Ultra-Luxe, in the Cashier's Cage.
 * Two Fat Mans can be bought (randomly?) from Blake at the Crimson Caravan Company.

Behind the Scenes

 * The Little Boy and Fat Man names are derived from the codenames of the atomic bombs used by the United States in World War II. Little Boy was dropped on Hiroshima and Fat Man was dropped on Nagasaki.
 * Just like in Fallout 3, the weapon is once again renamed to the Nuka Launcher in the Japanese version of Fallout: New Vegas.
