Carcass

The carcass is a new monster introduced in Doom Eternal. It appears to be the upper torso of a zombified human fused with a robotic chassis with three insectile-like legs and a blaster fused into its right arm. This blaster can fire ring-shaped lasers or create a wall-like force field to protect itself or other monsters at cost of mobility. The carcass appears to summon its energy shield most often in front of demons in the stagger state, to prevent the Doom Slayer from being able to easily glory kill them.

Pre-release
The carcass was first observed in footage released in March 2019 for the reveal.

Trivia
The force field created by the monster is similar to the shield wall from Doom (2016)'s multiplayer mode.
