Big Boy

The Big Boy is a unique weapon in Fallout 4.

Characteristics
The Big Boy has the exact same model as a regular Fat Man, but can shoot two mini nukes at once for the cost of only one, giving it the most damage potential from a single shot in the entire game.

Weapon modifications
The Big Boy is compatible with the same modifications of a Fat Man. One interesting note, if it is given the Experimental MIRV mod, the Big Boy will shoot an astounding sixteen mini-nukes, while only consuming one. Be aware that the blast radius from shooting this is substantially larger than normal.

Variants

 * Fat Man

Locations
Can be bought from Arturo in the Diamond City market.
