Fatman MIRV launcher (Fallout 76)

The  is a weapon modification in Fallout 76.

Gameplay attributes
By Adding the MIRV Launcher mod to the M42 Fat Man, the Residents gains the ability to fire more shells at once, while the principle of this weapon is similar to Fallout 3's Experimental MIRV, it has drastic negative effects.

While the principle of the weapon is similar to Fallout 3's Experimental MIRV, it has been "nerfed" in it's ability to output damage per shell, doing considerably less damage, and having a range to how far it can shoot. Based on the user's perks in heavy weapons, the shells can do more or less damage, but still less to the actual M42 Fat Man's single powerful shell. It has lost the point and kill nature that the Experimental MIRV had in Fallout 3, making the weapon more akin to a curio than something viable for engaged combat.
