Arachnotron - Weakness & Tips
Weakness: Gun Turret

The Arachnotron is a heavy demon that can fire continuously while moving. It is also very agile and mobile, making it a very dangerous demon for the unprepared. Destroying it makes it significantly easier to beat this demon.
Use Precision Bolt Or Sticky Bomb

You can effectively destroy the Arachnotron's Gun Turret using a Heavy Cannon's Precision Bolt Mod, a Shotgun's Sticky Bomb, or with a Ballista. 1 Sticky Bomb or one shot from either the Precision Bolt or the Ballista can do the job.
Get In Close After Destroying The Turret
After you destroy the Arachnotron's gun turret, you can now get in and shoot it from close-range. A point-blank Super Shotgun attack is very effective in bringing this demon down.
