Turret

The turret is an ambient demon featured in The Ancient Gods, Part One, the first expansion for Doom Eternal.

Tactical Analysis
The Turret will fire upon the player once they come into the Turret's field of view. Fire from the Turret is fairly tame and serves more as a nuisance than a threat. The Precision Bolt and the Ballista are the best weapons to use against this enemy, with a single shot forcing them to duck and hide. The Turret will also hide if the player's reticle lingers on them for too long.

Lore
Invented by the Hell Priest Deag Nilox centuries ago, Turrets contain imprisoned lesser demons that serve as stationary guards or their dark masters. Taking the form of a single unnatural eye and rising from their fellsteel containers to fire on any intruders nearby, Turrets defend the spaces around them and previously served as a direct visual link for their Hell Priest creator. With Deag Nilox now dead by the Slayer's hand the Turrets are directionless, and persist as undying traps that lash out with bursts of energy at anything that comes near.
