Carcass

The Carcass is a type of enemy that appears in the video game DOOM Eternal. It is a cybernetically augmented human corpse that has been imbued with demonic energy, turning it into a vicious killing machine. These monsters were created by Union Aerospace cultists who sought to assist the forces of Hell during their invasion of Earth.

Appearance
The Carcass appears to be a bloated human upper body that has been welded to a three-legged mechanical platform. Its flesh appears to be both molten and dessicated, with distinct folds of excess skin around the neck. Half of the creature's cranium has been replaced with cybernetics and its stomach appears to have been replaced with some sort of engine. It carries a cannon with its right arm that is fueled by a power pack on the creature's back. The robotic legs are multi-jointed and similar to those of a crab, allowing the Carcass to quickly scuttle about the battlefield.

Combat
In battle, the Carcass tends to keep its distance and confounds the Doom Slayer by projecting shield barriers between the Slayer and other enemies. It may also attack by projecting sonic blasts at the Slayer or by getting up close and battering the Slayer by spinning around on its tripod base.

The Plasma Rifle and Super Shotgun seem to be the most effective weapons to use against a Carcass. In fact, the Plasma Rifle and Ballista are capable of overloading the shield barriers that a Carcass projects; shooting a barrier with one of these weapons will cause it to explode and mulch any nearby enemies.
