Arachnotron (Doom Eternal)

The arachnotron returns as a monster in Doom Eternal, its first appearance in a main-series Doom game since Doom 64, and in any Doom game since Doom II RPG. As with previous versions of the monster, it is a brain-like monster equipped with a mechanical chassis that walks on multiple legs like an arachnid, essentially being a smaller version of the Spider Mastermind. Uniquely, this new incarnation carries its plasma weapon on a -like tail which it holds above its body.

The arachnotron attacks using its plasma gun, and is able to cling to walls and ceilings; if forced into close range or if its gun is destroyed, it attacks using claw swipes. Arachnotrons have been observed firing both continuous direct shots, and a burst of three arcing, lobbed shots.
