That's it... you're dead meat! Say hello to the Kneecapper!Ronald Laren

The Kneecapper is a unique sawed-off shotgun in Fallout 3.


A shotgun, also called a "scattergun," is a firearm designed to shoot a multitude of lead or steel balls of varying sizes, greatly increasing the weapon's hit potential. This makes it very effective at hunting game. However, the accuracy and power found at close range starts to diminish as the target gets farther away. Shotguns designed for the military's use are often called "combat shotguns."


The Kneecapper deals much more damage and is significantly more accurate than the regular sawed-off. The Kneecapper deals damage through raw power alone, since it does not deal any critical hit damage.


The Kneecapper can fire a total of about 111 shots, the equivalent of 56 reloads, from full condition before breaking. This is 56 fewer shots than the common sawed off shotgun.

  • It is possible to obtain two Kneecappers. The first by pickpocketing it from Ronald Laren while he is in Girdershade. The second by collecting another from his corpse if he is sent to the Nuka-Cola plant using dialogue from the Black Widow perk.
  • If Ronald learns of Sierra's death, he will refer to the Kneecapper by name as he attacks the Lone Wanderer.

Behind the scenes

The Kneecapper takes its name from the act of "kneecapping" someone, which is shooting them in the kneecaps to cripple their legs.
