Get ready for a wild ride through the fiery depths of DOOM! In this heart-pounding list, we’ll dive into the realm of chaos and spotlight the relentless adversaries that make every moment in this iconic game series a pulse-pounding challenge.
Cyberdemon:

The Cyberdemon, a formidable adversary in DOOM, takes center stage as the boss in the Lazarus Labs level. Representing a pinnacle achievement in Argent-Organic research, this creation of the Lazarus Project merges a Baalgar demon from the second Project Lazarus Manned Expedition with an Argent Accumulator. Its resilience demands permanent suspended animation, as attempts to subdue it prove futile – the Cyberdemon replenishes its life force, attacking with increased ferocity.
A colossal demon with pinkish skin and natural armor, the Cyberdemon wields a blade-like bone and a UAC-engineered rocket launcher. The fight involves two stages, each demanding strategic prowess. Samuel Hayden provides pre-fight insights. In the first stage, the player weakens the Cyberdemon in Lazarus Labs, triggering a glory kill. Teleporting into Hell, the Cyberdemon revives, initiating stage two with a corridor attack. The final glory kill involves removing the Argent accumulator and decapitating the Cyberdemon.
Dodge the Cyberdemon’s diverse attacks – missiles, charge attacks, aerial bombardments, laser targeting, and walls of fire. Movement is crucial to avoid damage, and careful observation of attack patterns is essential. A BFG shot stuns the Cyberdemon in low-health situations, dropping health vials. Siphon Grenades’ help and the Saving Throw rune prove invaluable. Ammo concerns? Switch weapons, as the Cyberdemon occasionally drops ammo packs. Navigate the Hell section strategically, utilizing gaps and corridors to your advantage. Face this demonic challenge, emerge victorious, and claim the achievement – “Shoot It Until It Dies.”
Arch-vile:

The Arch-vile, a formidable demon returning from Doom II, now wreaks havoc in Doom Eternal, replacing the Summoner. This demonic entity boasts the ability to summon a horde of demons, unleashing fire-based attacks on the player. Forged from Hellfire, the Arch-vile commands the unholy powers of Hell magic, making it a feared ruler among lesser demons.
Descending from the oldest demon lineage, the Arch-vile is prominent among high-born demon lords. With superior intellect and psychomancy powers, it dominates the savage denizens of Hell, bending them to its will. While its appearance maintains the iconic tall stature, various tweaks give it a more robust, spine-covered design.
As a master of fire, the Arch-vile’s attacks aim to burn the Slayer. This demon keeps the player on their toes, ranging from fiery waves to summoning lakes of flames. Its unique ability to summon demons erects a flame wall, shielding it from projectiles. The summoned demons gain enhanced speed and damage, akin to a Buff Totem effect, but this ceases upon the Arch-vile’s demise.
Immune to the Chainsaw and resistant to BFG projectile tendrils, the Arch-vile is a Super Heavy Unit that demands attention. Due to its health pool and potential to overwhelm with buffed demons, prioritizing its elimination is crucial. Tracking its frequent teleportations and closing in with the Super Shotgun’s Meathook is an effective strategy.
While the Lock-On modification for the Rocket Launcher seems promising, the Arch-vile can sense and evade it. Combining it with faltering weapons ensures the demon is denied the chance to escape. Frag Grenades, with the Combustion Concussion perk, or the Ice Bomb can falter the Arch-vile, canceling its summons. The mighty Crucible is also a formidable tool against this relentless foe.
Approaching the Arch-vile during its summoning phase is slightly easier, as it cannot attack. Interrupting its summons by faltering causes instant demise to any demons. Additionally, a Blood Punch can destroy the flame wall, providing an opportunity to falter or eliminate the Arch-vile more efficiently. Face the flames and conquer the Arch-Vile’s infernal challenge!
Revenant:

The Revenant, making a return in Doom Eternal, retains its jetpack from Doom (2016) with slight design adjustments to align more closely with its original Doom II appearance. Initially considered eradicated with the UAC facility’s collapse on Mars, the Revenant program resurfaces with Cultist enclaves on Earth, now under Hell’s direct control, spearheading a renewed production wave. The cyber-neural programming sees modifications, inducing frenzied bloodlust and a compulsion for death and violence in the host.
Visual aspects echo Doom (2016), presenting a tall skeleton adorned with a UAC Jetpack and dual Multiple Launch Rocket Batteries. However, a tidier look with less blood and cleaner bones aligns it with the Doom II sprite. Operating at mid to long distances, the Revenant targets the Slayer with shoulder-mounted rocket launchers. It frequently unleashes twin rockets and, occasionally, a homing missile barrage that demands agile evasions.
The Revenant’s jetpack provides enhanced mobility, allowing it to strategize attacks from cover and evade the Slayer’s weapons. Disabling the jetpack involves destroying both rocket launchers. Various tactics can subdue the Revenant: the Rocket Launcher’s Lock-On modification delivers a one-shot kill, negating its evasiveness; using the Ballista inflicts increased damage while the Revenant utilizes its jetpack. Targeting its launchers weakens the demon, reducing damage output and prompting it to close the distance. Destroying one launcher causes a momentary falter, offering a window to easily remove the second. Face the Revenant strategically, exploiting its vulnerabilities to emerge victorious.
Marauder:

The Marauders, featured in Doom Eternal and its subsequent DLC releases, are resurrected and corrupted Night Sentinels who once served the Khan Maykr and Hell Priests against Argent D’Nur. As demonic sentinels and former Doom Slayer’s warrior band members, they possess powerful techniques, making them formidable adversaries throughout the campaign.
During the civil war in Argent D’Nur, the Night Sentinels Guard faced a dilemma: allegiance to the Khan Maykr and revolting against their sworn protectors. Those disillusioned forsook their oaths, joining a separatist group led by exalted Priests. Resurrected by the Divinity Machine of Maykr design, these fallen Sentinels became Knights in Hell’s army, dedicated to hunting the reborn Slayer.
Marauders wear Sentinel armor with earthy green tones, revealing pale-white skin and visible dark veins. Armed with large battle axes of Argent Energy and double-barreled shotguns, they deploy an Argent Energy shield for defense. The demonic resurrection imparts skull-like facial features, glowing red eyes, and claw-like nails.
Understanding the Marauders’ combat dynamics is crucial. They employ diverse attacks at different distances, from energy beams to shotgun blasts and axe lunges. Summoning a wolf for assistance follows damage absorption with their shield. Effective combat involves encouraging engagements at medium distances and exploiting vulnerability during mid-lunge.
A recommended strategy is to wait for the Marauder’s axe swing and bombard them with Micro Missiles, particularly if the mastery is completed. They are durable, immune to Ice Bomb and Chainsaw, and can block the BFG’s tendrils. However, splash damage from explosive projectiles proves effective, especially at longer ranges.
Despite their formidable nature, Marauders demand constant attention, and the player must remain vigilant to the surroundings. Focusing solely on a Marauder might create openings for other demons, emphasizing the need for strategic awareness in battling one of Doom Eternal’s most dangerous enemies.
Hell Knight:

The Hell Knight returns in Doom Eternal, maintaining its resemblance to the Doom (2016) iteration but with noticeable design changes. The campaign introduces a cybernetically enhanced variant, the Dread Knight. As a warrior beast among demons, the Hell Knight has long served the eternal Archdemons, acting as brutal enforcers in the Netherworld. Adhering to the hierarchy’s rule, Hell Knights willingly serve demon lord masters, finding satisfaction in war and desecration.
While its design mostly aligns with Doom (2016), distinct differences include beady eyes embedded in its skull and a lighter color scheme, shifting from dark brown to snowy white armor and a more prominent purple body. The Hell Knight’s well-built muscle structure remains, with denser neck muscles compared to its previous iteration. Behaviorally, it mirrors its Doom (2016) counterpart, rushing the player with powerful punches and ground slams.
Unfazed by most weapons, the Hell Knight charges relentlessly, posing a challenge that demands strategic engagement. Being devoid of ranged attacks, keeping it at a distance is crucial. Fully automatic gunfire proves effective, increasing the chance of faltering the Hell Knight and temporarily halting its charge. Early-game options like the Heavy Cannon’s Micro Missiles and Combat Shotgun’s Full Auto modification work well, while the Chaingun and Rocket Launcher offer potent alternatives for shredding the Hell Knight quickly. Adapt your tactics to face this relentless demon and prevent it from unleashing devastating damage.
Pain Elemental:

The Pain Elemental, or Pain for short, returns in Doom Eternal with notable visual and behavioral changes from its Doom II depiction. This abhorrent creation of the Umbral Plains, originating from the demonic depths, is cursed to forge Lost Souls within its fiery gut, subject to endless torment. Its only respite comes from projecting suffering into the world, deriving satisfaction from indiscriminate killing and inflicting misery on the weaker.
While maintaining the general appearance of its original design, the Pain Elemental exhibits significant alterations. Its jaw now features human-like separation, surrounded by articulated mandibles capable of individual movement. A more slender body, enlarged horns, and a rear end resembling Armadillo armor distinguish the creature. Its eye transforms from black to a glowing orange, and larger, elongated arms end in three claws each.
Possessing considerable health, the Pain Elemental serves as a bullet sponge, requiring concentrated fire for elimination. The Ballista proves effective, although multiple shots are necessary. The Super Shotgun’s Meat Hook enables close encounters for high damage. The Rocket Launcher’s Lock-On modification deals significant damage but requires at least two bursts for a kill. Evading the barrage of hurled Lost Souls, players must relentlessly attack until the Pain Elemental succumbs to the onslaught. Adapt your strategy to face this tormented demon and unleash a relentless assault to overcome its formidable resilience.
Mancubus:

The Mancubus, a Heavy Tank-like demon in Doom Eternal, fulfills its role similarly to DOOM but undergoes significant design changes to closely align with its original appearance. The Cyber Mancubus, a stronger variant of Doom (2016), also reappears. This hulking behemoth of the demon world stands out with clear signs of man-made modifications, featuring armor-plating augmentation and a sophisticated arm-mounted weapon system. These enhancements aim to upgrade and weaponize the Mancubus’s formidable fighting capacity, making it a resilient and threatening force in battle.
Compared to its Doom (2016) depiction, the Mancubus in Doom Eternal more closely resembles its original sprite from Doom II. Retaining its overweight stature, massive dual-arm cannons, and squat stance, the demon exhibits a stitched-together appearance with visible signs of stretching and tears. Notably different is the heart-like organ in the center of its chest, serving as the power source for its attacks.
Functioning as a tank, the Mancubus can deliver significant damage while withstanding attacks. It shoots powerful flame balls from a distance, gradually approaching the Slayer. At medium to close ranges, dual flamethrowers rapidly damage the player. Caution is advised due to the flamethrowers’ surprisingly long reach. Face-to-face encounters lead the Mancubus to fire its cannons into the ground, creating a damaging puddle of napalm.
Mitigating the Mancubus’s attacks involves destroying its arm cannons. This eliminates flamethrowers and weakens the fireball attack. Given its slow movement speed, constant fire at the demon’s large frame is effective. Notably, performing a Glory Kill or Chainsawing the chest area results in a violent explosion after approximately 3 seconds, dealing massive damage to nearby enemies. Employ this strategy to control opposing demons and create breathing room for handling the next significant threat.
Cacodemon:

The Cacodemon, an aerial heavy enemy in Doom Eternal, roams the Sloughlands of Hell in search of easy prey. As an aimless wanderer, the Cacodemon lacks cognitive ability, sensory awareness, and common impulses driven solely by the singular desire to feed. Wherever there is flesh to be consumed, the Cacodemon appears with an insatiable hunger, bearing a resemblance to the cycloptic titans of ancient Hell lore, as believed by Sentinel scholars.
Remaining largely unchanged from its depiction in DOOM, the Cacodemon retains its shriveled legs and misshapen underbelly. However, its back spines and teeth transition from a dirty yellow to a clean white color, and its body adopts a lighter shade of red. The green eye now sports a pupil, and it bleeds blue blood, reminiscent of its appearance in the classic Doom games. Drifting quietly towards the player, the Cacodemon lobs balls of purple plasma, attempting to close the distance. Occasionally, it launches three plasma balls in quick succession, posing a threat to the player’s mobility. At close range, the Cacodemon bites the player, dealing significant damage. Despite its bulk, the Cacodemon withstands substantial damage without flinching.
Exploiting its weaknesses is key to overcoming the Cacodemon. The most obvious vulnerability is its mouth, making it susceptible to frag grenades or Combat Shotgun Sticky Bombs. A well-placed explosive into the gaping maw results in an immediate stagger, allowing for an easy Glory Kill. The Ballista, especially with the Arbalest mod, also proves effective at range, delivering increased damage against flying foes and one-shotting the Cacodemon.
Imp:

The Imps make a comeback in DOOM Eternal, appearing from the beginning and persisting as a consistent adversary throughout the campaign.
While retaining their hunched-over design from DOOM, the Imps have undergone slight modifications to closely align with their original series appearance. As scavengers of the underworld, Imps are prevalent on the scorched surface of the Hellscape. Possessing limited intelligence, these lesser demons are driven by a hunter’s instinct to seek out prey, making them ideal foot soldiers easily manipulated by high-borne demons in the warring legions of Hell. Deployed at the forefront of offensive attacks, Imps serve as expendable resources unleashed in great numbers to overcome and break through enemy fronts.
The Imps in DOOM Eternal feature a slightly altered appearance compared to their 2016 counterparts, showcasing elongated back spines and pupiled orange eyes more closely to resemble their original design. Despite these changes, they maintain their agility, attacking the player from a distance with hell-fire balls and swiftly traversing terrain. Behaviorally, Imps resemble their previous counterparts, throwing hell-fire balls from a distance, clawing at close range, and having the ability to charge up a larger hell-fire ball that inflicts significant damage. Unlike their 2016 counterparts, Imps do not cling to walls.
Despite their mobility, Imps have low health and can be easily dispatched with any weapon. Interrupting their charge of a large hell-fire ball by shooting them causes temporary stun, providing an opportunity for an easy kill.
Pinky:

The Pinky makes a comeback in Doom Eternal, reappearing early in the game at the Doom Hunter Base.
Remaining essentially unchanged from DOOM, the Pinky maintains its distinctive features with an armored front capable of withstanding high amounts of damage and a vulnerable rear end. However, the tail explicitly becomes a designated Weak Spot in the sequel. As Hell infiltrated Earth, the Pinky became a prevalent menace to ARC military fortifications. Utilizing its formidable armored frontal carapace, the Pinky could breach defensive encampments, breaking through walls and employing its ramming ability to overturn and immobilize armored vehicles. The ARC, reliant on holding the line against Hell’s forces, faced disruption and potential overrun by a single Pinky, allowing greater demon influx after its breakthrough. Recognizing the threat, the ARC prioritized the Pinky as a high-range bombardment target to prevent its approach.
The appearance of the Pinky in Doom Eternal closely mirrors its DOOM counterpart, featuring a pink body reminiscent of the original Doom games’ Pinky. The Doom Eternal Pinky has yellow eyes, similar to the original Pinky, and cleaner-looking spines akin to the Cacodemon in Doom Eternal.
While behaving similarly to its DOOM appearance, The Pinky’s armored front has become more resilient, capable of withstanding Super Shotgun blasts and Ballista bolts. Unlike in the previous game, the protective plates covering its head cannot be blown off for an additional weak point. The Pinky turns around faster after a missed charge, making exploiting its rear weakness in enclosed spaces challenging.
However, new weaknesses have been introduced. The Ice Bomb can freeze the Pinky, exposing its rear weak point for an easy kill. The Pinky is particularly susceptible to the Blood Punch, succumbing to a single strike even from its armored front. When charging, the Pinky has a limited turning radius, allowing a nimble player to use a well-timed dash to dodge the stampeding demon and attack its weak point before it can turn around. Alternatively, players can double-jump over the Pinky and fire on it from above as it runs past. The Pinky takes increased damage from shots to the rear, making a few well-placed shots from most weapons effective. A point-blank Super Shotgun blast to the rear can instantly eliminate a Pinky.
Surviving the relentless onslaught of these formidable DOOM enemies is a testament to your gaming prowess. Whether you’re a seasoned slayer or a newcomer to the series, facing these adversaries is an adrenaline-fueled journey into the heart of gaming chaos. So, gear up, lock and load, and prepare for an epic battle against the toughest demons in DOOM!
