Arachnotron/Doom 64

"Think of the pain a Black Widow causes when you disturb her nest. Then think what happens when you stir up one the size of an M60 tank."

- Doom 64 manual

Arachnotrons appear in Doom 64.

Background
The Arachnotrons of Doom 64 are the resurrected carcasses of those from Doom 1 presumably from the Spider Mastermind him/herself (or from PSX and Saturn Doom since there are no Arachnotrons in Doom Classic's campaign), resurrected by the Mother of All Demons. They are made from systematically altered dead carnage remade back into corrupted living tissue. The mutations were devastating. The Demons have returned stronger and more vicious than before.

Think of the pain a Black Widow causes when you disturb her nest. Then think what happens when you stir up one the size of an M60 tank.

Their physicality is considerably altered and mutated; the mechanical body is much bigger, with the brain head ducked down inside the machine itself instead of sitting atop it, also not having any organic arms like the classic version, and the mechanical legs (now six instead of only four) being longer and bent at upwards-pointing acute angles. Instead of a single plasma gun, the Doom 64 Arachnotrons possess two guns that fire out two blue plasma bolt shots simultaneously, but done so in spurts of five instead of a constant rate of fire, though it will continue firing as long as it can see the player.

Info
They first appear in MAP14: Eye of the Storm unless the player goes through MAP30: The Lair and MAP32: Hectic, which contain Arachnotrons but chronologically come first.
