Cueball

The Cueball is a monster in Doom Eternal. It's basically a reincarnation of the Possessed Engineer from Doom (2016)

Appearance
Cueball's appaerance are similiar to it's previous incarnation, only different from it's previous incarnation are mumps-like neck and big belly with several flaming red fuel canister that fused to it's body.

Combat Characteristics
Unlike it's predecessor, Cueballs do not attack their enemies. Instead, they are ambient monster used as living bomb, by shooting them, make them bouncing off to target's direction, blowing their fuel tanks, which trigger an explosion that deals heavy damage.

Tactical analysis
The Cueballs are not that big of a threat compared to other monsters as they act just like the Possessed (zombie, soldier (blaster) and soldier (shield)). However, they should be taken out from a distance because of the highly explosive fuel tank embedded in their chest. The player can also use the tank as an advantage by shooting the Engineer while it's standing in a big crowd of monsters, as the resulting explosion will damage or kill all nearby enemies. Glory Kills end with them being kicked away, saving the player from damage while potentially throwing the Engineer into other enemies before exploding.
