- "What the !@#%* is this!"
- ― Doom 64 when collecting the weapon.
The Unmaker (aka Unmaykr or Laser) is a weapon found in Doom 64 and Doom Eternal.
The Unmaker's appearance in Doom 64 is of a demonic theme and is arguably considered the most powerful weapon in the series. Shooting lasers that cause high amounts of damage. The Unmaker can be upgraded by playing through the secret maps and acquiring the Demon Keys to upgrade it's firepower. The weapon is especially effective against the Mother Demon on Map 28: The Absolution (And the "Resurrector". Which is another Mother Demon you fight on Map 39: Final Judgement.) once all three keys are obtained. However, the relation between this weapon and the demons remains a mystery.
The Unmaker reappears in Doom Eternal now known as the Unmaykr. Fitted with Maykr technology, inspired by Sentinel weaponry and refined by their "Divine Intellect." In comparison with it's Doom 64 design, the Demonic theme of the weapon is discarded for a completely angelic appearance like that of the Maykrs. Which can be considered irony in a sense due to the sinister nature that the weapon depicts both in Doom 64 and in Doom Eternal.
Behind the scenes
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 Dark Claw and Unmaker feed on human souls. Killing possessed humans or hellslaves allows the weapons to feed". This idea was later used in Doom 3's Soul Cube and Resurrection of Evil's The Artifact.
