Spiderdemon



The Spider Mastermind, also called the Spiderdemon, is the boss of Episode III of Doom ("Inferno") and Episode IV of Ultimate Doom ("Thy Flesh Consumed"). It has 3000 hit points and is one of the toughest creatures in the game. It is female.

The Spider Mastermind is armed with a rotary gun that has the sound of the shotgun but with a spread similar to the player's chaingun; in fact, it is essentially an automatic version of the Sergeant's shotgun, firing three pellets per shot at a rate of 425 shots per second. When a Spider Mastermind begins firing, she will not stop until her target moves out of her view or dies; or if she is stunned (causing her to move) or killed. Similar behavior can be observed with the Chaingunner and Arachnotron.

The Doom II game booklet says:
 * The Spider Mastermind: You guess the Arachnotrons had to come from somewhere. Hi, mom. She doesn't have a plasma gun, so thank heaven for small favors. Instead, she has a super-chaingun. Crap.

The Spider Mastermind is not mentioned in the Doom game booklet, presumably to avoid a spoiler. Perhaps as a result of this, the game booklet for the Depths of Doom Trilogy erroneously states that she appears in Doom II only.
