A portable nuclear bomb catapult. "Deadly" is an understatement.— In-game description

The Fat Man is a weapon that appears in Fallout Shelter.


Portable, shoulder mounted nuclear launcher found in Fallout Shelter. Weapon and associated ammunition, the mini nukes are heavy and relatively rare in the wasteland with little practical use against smaller, weaker enemies, but large groups of opponents can be dropped quickly with one or more bombs. Extreme care must be taken when operating the nuclear launcher as the blast radius can easily extend back to the shooter if shot too close to one's self.


The Fat Man is a nuclear launcher featured in Fallout Shelter. Dealing 22 minimum damage per attack, it has the second lowest damage output for a heavy weapon in the game. The Fat Man also damages multiple opponents per shot.

Contrary to what one might expect from a nuclear catapult, all variants of the Fat Man in Fallout Shelter are poor choices for combat against multiple opponents. Refer to the weapons page for details.
