Maykr drone

The Maykr drone, the lowest-ranked known form of the Maykrs, is an enemy in Doom Eternal, found mostly within Urdak, as well as in one of the Slayer Gate challenges. They fire sustained volleys of Argent projectiles, and feature a massive drop of loot if killed with a headshot.

Tactical analysis
Maykr drones tend to stay a fair distance from the player and shoot volleys of weak energy blasts; in melee, they attack with whips of light. Their bodies are covered in strong armor that makes them surprisingly durable for a fodder monster, but their heads are highly vulnerable - additionally, killing them with a headshot will release bonus health and ammunition. The heavy cannon's scope mod is especially effective. It should be noted that Maykr drones require three fuel pips to kill with the chainsaw rather than the single pip needed to kill other fodder monsters.

Lore
Drones make up the majority of Urdak's population; like most other Maykrs, they have individual identities but are biologically unable to defy an order from the Khan Maykr. As a result, they give the impression of functioning as a perfectly synchronized colony. Their bodies, referred to as being immature, are not yet able to handle the strain of inter-dimensional travel, so they never leave Urdak.
