Big Boy

The Big Boy is a unique weapon in Fallout 4.

Characteristics
The Big Boy is a Legendary Fat Man with the Two-Shot prefix, allowing it to 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.

The Big Boy is compatible with the MIRV launcher mod; the Big Boy will shoot an astounding twelve mini nukes, while only consuming one. Be aware that the blast radius of this weapons' mini nukes substantially larger than normal and that the nukes lose their momentum and fall to the ground after splitting. Also, the cost of this weapon is astoundingly high (the most expensive item in the game), at around 14,000+ caps with no charisma and charisma related perks or effects.
