Unmaker

Unmaker is a weapon from Doom Bible which was meant to be in Doom, but was eventually removed.

According to the Doom Bible, the Unmaker was intended to be a "demon-tech weapon that hurts pure demons a lot, demon-humans very little, tech demons some. Made of demon bones." "The Darkclaw and Unmaker feed on human souls. Killing possessed humans or hellslaves allows the weapons to feed."

The Unmaker appears in Doom 64.
