Codex



The codex is the protagonist's mobile database of information on monsters, weapons, items, upgrades, and plot elements in the Doom and in Doom Eternal. It automatically updates with new information as monsters are killed and items are collected, and can be referenced at the player's convenience, taking the place of Doom 3's PDAs and functioning in a manner similar to the scan log in the  series. Some data log messages are acquired from datapads.

Fodder
Zombies- Possessed by the influence of Hell, these once human underlings that follow in Hell's ranks are those that have been corrupted and deceived by its power, forsaking their own humanity. Those who have fully succumbed to Hell's control cannot be saved, becoming mindless, grotesque contortions of their former selves.

Imps- Scavengers of the underworld, Imps are among the most common of beasts found on the scorched surface of the Hellscape. Lesser demons of Hell, the imp possesses limited intelligence, driven only by a hunter's impulse to seek out prey- a task for which the imp is naturally suited due to its innate capacity for violence. As a result of these attributes, the imp makes for an ideal footsoldier and is oft deployed in the warring legions of Hell, easily manipulated and controlled by commanding highborne demons at the behest of the sovereign chapters. It is common for the imp to appear at the frontline of an offensive attack, an expendable resource unleashed in great numbers to overcome and break through the enemy front.

Soldiers- Once frontline infantry fighting to protect Earth from the demon invasion, the Hell Soldiers have been claimed by darkness, turning them against their fellow soldiers in the midst of battle.

Gargoyle- Like their Imp brethren, the Gargoyle is an agile, relentless pack hunter. Native to the Sentinel world, this beast has plagued the Sentinel Guard for centuries. As one of the few demon breeds that could bypass the walled defenses of Sentinel Prime, the Gargoyle could appear without warning and claim hapless townspeople before disappearing into the wasteland. Only the most skilled marksman of the Night Sentinels could intercept this aerial threat, a peril with demanded an ever vigilant watch over the city's perimeter.
