Arachnotron/Doom Eternal

The Arachnotron is a returning monster that appears in Doom Eternal and a spawnable demon in Battle mode                                                                                                                        

Physical Appearance
The design is very similar to the Arachnotron's original appearance in Doom 2, the only big difference being that the cannon is now on top of the brain (in the fashion of a scorpion's poisonous tail) rather than below its brain.

Combat Characteristics
The Arachnotron in Doom Eternal can climb walls at any angle, jump long distances, and can shoot plasma from the cannon on top of its head. It can also fire grenades at the player, and also has a melee attack. While the Arachnotron is on a ceiling or wall the player can shoot its legs and make the Arachnotron fall. The player should target and disable the Arachnotron's plasma cannon as soon as possible.

Strategy
The Arachnotron was designed to be defeatable by early weapons, so early weapons are what you should use. The Combat Shotgun with the Sticky Bombs Mod is very handy, since a single bomb is enough to destroy the turret. Also the Heavy Cannon 's Micro Missiles are likely to hit the turret.

Once the turret is destroyed, almost any weapon is viable to kill the Arachnotron. Be careful though, since it will be running at you in attempts to melee, so the Rocket Launcher could be risky if it is about to run towards you.
