Item from Fallout by Interplay / Bethesda
Tactical nuclear warhead the size of a football, still radioactive after two centuries — ammunition for the Fat Man launcher and the most dangerous single object you can carry in your pack.
Carrying one changes your relationship with everyone around you. It's leverage, insurance, and a death sentence all in one package. A single mini nuke can level a building, irradiate a city block, and end any standoff — but it also makes you the most valuable and most dangerous target in any room.
Roughly football-sized metal ovoid with cooling fins and a blinking amber arming indicator. The casing is stamped with military serial numbers and radiation trefoils. It's warm to the touch. The paint has faded from olive drab to a sickly yellow-green.
Also known as: Nuke, Tactical Nuke, Nuclear Warhead
