"Dusted!" —Grayson Hunt
It is a four-barreled shotgun that shoots extremely powerful compressed-air shells, which will push your target away from you. This allows the player to then interact with the environment or completely rip the enemy in two.
When charged, the Boneduster will send out a shockwave which is so powerful it can cut through cover. At far range, the Boneduster does little to no damage.
Skull Shotgunners also use Bonedusters and are quite dangerous. They are easily identified by their size, and buffalo skull masks.

Note: many of these skillshots will be granted alongside environmental 'shots, as the Boneduster pushes people around easily
- It is hinted in this video  that the inspiration for the Boneduster may have been from Cliff Blezinski's desire to include a shotgun-esque weapon in the original Unreal that was never completed. The weapon was named the Quad Shot and had four barrels, like the Boneduster.
- When it's primed to charge, Grayson cocks the gun, unlike using normal mode. It is unknown how it is charged this way.
- When charged, the shockwave can kill a Miniboss in one hit, granting you the Bossed skillshot. This one hit kill only applies when dealing with the Chaingun-wielding Miniboss, or after knocking off the armor of the other two varieties.
