Usage & Description
The Bone Shredder is a returning weapon from Borderlands, using a different manufacturer in this iteration but retaining the same core feature of firing multiple bullets per shot. While this was not a rare feature of submachine guns in Borderlands it is in Borderlands 2, as there is no standard "double" submachine gun accessory in the latter. Thus the Bone Shredder is one of a very small number of submachine guns which output multiple pellets per shot, only other examples being the Lascaux, Sand Hawk, Slagga, and Tattler.
In addition to the changed manufacturer, the Borderlands 2 Bone Shredder also has a more flexible parts list than its predecessor, allowing it to potentially have a larger magazine size, higher fire rate, and most notably an elemental capacitor. It also fires another pellet with every shot, making the total three pellets per shot, which combined with the elemental capacitor makes it a very deadly purple submachine gun.
Though this would all seem to make the newer Bone Shredder vastly improved over its previous iteration, the previous improvements are nullified by its low accuracy. This severely limits the weapon's usable range even when zoomed in unless at extremely close range or against larger enemies.
- The Bone Shredder was dropped from Son of Mothrakk on Day 25 of the Borderlands 2 $100,000 Loot Hunt. A hotfix on that day increased the number of pellets fired to 3 and gave it an increased magazine size and damage rating.
- The Bone Shredder is a returning weapon from Borderlands but as a bandit submachine gun instead of Tediore.
- The Brady Games strategy guide incorrectly lists the Shredifier and the Bone Shredder dropping from Bone Head 2.0 in the Vladof and Bandit sections of the weapons guide, respectively.
- Despite now being a bandit weapon, the Bone Shredder retains the monochromatic color scheme of Borderlands Tediore weapons, due to it being a returning weapon.
