If forced into close range or if its gun is destroyed, it attacks by swiping at the Doom Slayer with its leg claws or by firing grenades. The arachnotron's turret is its weak point, and can be destroyed due to the new destructible demons gore mechanic. It is able to cling to walls and ceilings to stay out of reach, but attacking its legs in this state will cause it to lose its grip and fall. The arachnotron attacks using its plasma gun for continuous direct shots and the grenade launchers for lobbed area-of-effect shots.
