Fat Man (Fallout 4)

The M-42 or M42 Fat Man is a weapon $$

Gameplay
Developers struggled to find a way to fire the heavy ammunition from a man-portable system far enough to keep the operator outside the blast radius. Eventually, it was discovered that by placing a small sub-charge into the ammunition itself, similar to bullets being fired from a gun, the warheads could be launched a considerable distance without adding too much weight to the already heavy weapon.

When fitted with the MIRV Launcher, it fires six Mini Nukes in a cluster that separates in mid-air, drastically reducing its range, but increasing its overall damage and area of effect.

Variants

 * Big Boy, a unique version with the Two Shot legendary modification.
 * The Striker, a unique version that fires modified bowling balls instead of Mini Nukes.
 * Nuka-Nuke Launcher, a unique version that deals 50% more damage than the standard model by firing quantum-enhanced Nuka-Nukes.
