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. A special kit, ominously titled "Little Boy", makes the weapon weigh less. The Little Boy and Fat Man names are derived from the codenames of the atomic bombs used by the United States in WW2. Little Boy was dropped on Hiroshima and Fat Man (the more powerful of the two, as it was a Hydrogen bomb) was dropped on Nagasaki, both of which are located in Japan.

Appearances
The Fat Man appears in Fallout: New Vegas and Fallout 3
