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.

When fitted with the MIRV launcher, it causes the initial projectile to split into six smaller projectiles halfway across its arc of trajectory that spread out and fall downwards, nearly halving its range but increasing its overall damage and area of effect
