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 what is presumed to be a plasma weapon on a -like tail which it holds above its body.

The Arachnotron attacks using its plasma gun, and is able to climb up walls; if forced into close range, it attacks using claw swipes.
