Bone mashers are a necromorph, and are similar to Slashers.
Bone mashers are large and human like, they have scar tissue were their mouth and nose once had been, and both eyes have been joined together into one. Their arms and hands have lost all of their skin, and the bone underneath has been hardened. Their hands have been turned into large, spike covered bone clubs.
Bone mashers have no special abilities or attributes. They are fairly slow, but have strong attacks which will deal lots of damage.
