Devastator

The ironclad Devastator seeks to crush opponents of the Automatons' totalitarian worldview with a diverse array of heinous weaponry: arm-cannons, arm-shields, arm-machine guns, and shoulder mounted multiple rocket launchers.

They can be divided into three types:
 * Standard - Devastators equipped with cannons.
 * Heavy - Devastators equipped with machine guns and shields.
 * Rocket - Devastators equipped with shoulder mounted multi-rocket launchers.

Tactics

 * The body of a Devastator is protected by medium armor and thus can soak up a decent amount of small arms fire, however, their heads are fully exposed, allowing Helldivers to quickly down them if aimed there.
 * Despite their slow movements, they'll use different weapons to try and target any Helldiver. The best bet is to use shotguns or heavier weaponry on their limbs, which can slow them down or remove their weapons.
 * For the tougher variants, explosives and stratagems (like the Eagle Cluster Bombs, Barrages, and Autocannon) are excellent at taking them down.
 * The shield of a Heavy Devastator is classified as heavy armor and require high caliber weapons such as the Railgun to penetrate. However, the shield is not large enough to protect their heads and their machine gun arm. A Helldiver can shoot off a Heavy Devastator's machine gun arm which leaves it only capable of performing a shield bash melee attack.
 * Heavy Devastators have unarmored power packs mounted on their backs that can be destroyed by small arms in order to kill the Heavy Devastator.
 * The rocket variant can be especially deadly and troublesome, especially when there are multiple units of them present, as their rockets not only pack a tremendous punch but are also fairly accurate. Thankfully, their rocket pods can be destroyed with concentrated fire. Attacking them can also prevent an impending launch via staggering them, which can save lives.
 * Rocket Devastators telegraph their attacks by taking a wider stance and leaning forwards, as if to brace for the rocket pods' recoil, if a Helldiver is unable to disarm them in time, it's time to take cover or dive out of the way.
