Fat Man (Fallout 4)

The M42 Fat Man is a weapon in Fallout 4.

Characteristics
First entering service in September 2077 with the U.S Army, the Fat Man is a shoulder mounted mini nuke launcher. The Fallout 4 variant has a slightly different appearance than in previous games. There is no longer a handle on the right side of the launcher, and instead two straight handles on the bottom. It also appears to be larger, with a rusted silver paint job. Developers struggled to find a way to fire the heavy ammunition from a man-portable system far enough to keep the operator outside of the blast radius. Eventually, they decided to use a propellant charge within the ammunition itself similar to bullets being fired from a gun except that mini-nukes are "caseless" cartridges, and there is no true "barrel" on the weapon, likely to reduce weight.
