"They are rage, brutal, without mercy.
But you. You will be worse.
Rip and tear, until it is done."

Doom is the 5th (Doom, Doom 2, Doom 64, Doom 3, 2016) main installment in the Doom franchise, developed by id Software and published by Bethesda for the PC, PlayStation 4, and Xbox One on May 13, 2016.

You play as a silent, unnamed Space Marine who wakes up in a creepy stone coffin surrounded by zombies. After fighting your way through them and acquiring a suit of Powered Armor from an equally-creepy nearby sarcophagus, you discover you're inside a Union Aerospace Corporation facility on Mars in the middle of a demonic invasion. What were you doing in a coffin? Irrelevant. Why are demons invading Mars? Doesn't matter. You're a berserker-packin' man and a half who's here to Shoot Everything That Moves until The Legions of Hell are obliterated. Rip and tear, until it is done.

Originally announced in 2008 as "Doom 4", the game is meant to be a Genre Throwback to the early days of First Person Shooters; back when guns didn't need reloading, cover was for sissies, players could carry more than two guns at once, and levels were more than just linear hallways interrupted by quick-time events. Having said that, it does preserve a number of features from modern FPS titles: Gun Accessories that provide alternate-fire modes, having grenades and Pistol Whip assigned to their own buttons (a la Halo), melee-range "Glory Kill" Finishing Moves that allow you to (gratifyingly) beat foes to death with their own limbs and (gratifyingly) collect extra health and ammo pickups from their disfigured corpses, and some Info Dumps hidden in the Encyclopedia Exposita. The game also features competitive multiplayer, where up to twelve players duke it out in a variety of game modes, and a Level Editor called SnapMap, which allows one to create their own map with custom game logic.


DOOM provides examples of:

  • 100% Completion: Most levels have three bonus objectives to complete, a combat rating that goes up by killing enemies, and numerous collectibles, mods, and secrets to find.
  • Action Bomb: Lost Souls fly straight towards you, kamikaze-style.
  • Actionized Sequel: While Doom 3 was more of a survival-horror, this entry is a straight-up action game in the vein of the first two.
  • Adaptational Villainy: In Doom 3 the UAC were somewhat amoral, but were surprisingly sensible and generally averted the stupidity of most evil corporations like Umbrella. In this Doom, the UAC operate like a cult and are essentially a combination of Satanism and Unitology, getting there by way of Weyland-Yutani, but Played for Laughs (most of the time) while operating with a hilariously cavalier attitude towards the death of their employees. Oh, and they don't let their employees take the weekends off. Those monsters.
  • Affably Evil: Well-Intentioned Extremist Samuel Hayden, who is unfailingly polite to the Doomguy and assists him throughout despite their at odds agendas - even after Doomguy repeatedly thrashes the UAC facility against his protests, he continues to assist him, and never has anything worse to say than some passive-aggressive comments on Doomguy's preference for violence. Even after turning on Doomguy, he admits Doomguy might be right to completely obliterate Hell, and merely sends Doomguy to parts unknown to keep him from interfering, partly because killing him would be rude, and partly because he's not sure if he can kill him. He also sincerely thanks VEGA before its sacrifice and meltdown.
  • Anti-Frustration Features: Glory Kills drop additional health and ammo if you're running low on either, with more stuff dropping the fewer you have. You can also perform them from slightly outside normal melee range, and are impervious to damage from other demons before and after.
    • At the higher difficulty levels the glory kills are a godsend when low on health. The chainsaw in particular will be used almost like a get out of jail free card when low on health and ammo & facing tough enemies.
  • Apocalyptic Log: Codex entries detail the decline of UAC as more members succumb to demonic influence. Amusingly, the demons have their own in the form of the Slayer Testaments, which tells the tale of the Doomguy's nigh-unstoppable rampage through their realm and how they're all terrified of him.
  • Are These Wires Important?: Doomguy's preferred method for dealing with Argent Energy equipment, despite Hayden's demands that he use utmost care.
  • Artifact of Doom: The Crucible.
  • Artificial Brilliance: Go ahead, try to hide somewhere. Not only were most of the combat arenas designed so that just about every point is accessible to the demons (who climb, flank and shuffle around from every other angle, especially Imps), but they usually lock off hallways to prevent the player from just picking off enemies one by one in tight corridors. And they'll be more than happy to use this against you. Heck, a large number of foes even predict your movement and try to fire ahead of your path unlike the rest of the series, especially in Ultra-Violence, But...
  • Artificial Stupidity: Enemies also have a bad habit of flaunting or contemplating what to do next, particularly larger enemies, which leaves them wide open to a rocket in the face to knock them out of their stupor. The aforementioned Imps in particular can throw fireballs while running and love to be quite aggressive - up until they decide to stand in place chucking more fireballs while you barrel towards them with a shotgun.
  • Ascended Meme:
    • The opening cutscene quotes the phrase "Rip and Tear" from the Doom comic, though the context is different enough to make it chilling.
    • There are a huge number of trophies quoting the Doom comic.
    • One fan name for the Doomguy, "The Doom Marine," is now what UAC calls him in-universe.
      • Likewise the "Demon" enemy returns and is now officially called by his fan name "Pinky".
    • The achievement for killing the Cyberdemon is called "Shoot it until it dies.", referencing a GamePro Magazine issue that gave that as a joke protip.
    • The "Doom Shuffle" multiplayer taunt is from a popular YTMND .gif edit of the Doomguy doing this cheerful little move.
  • Ascended Fanfic: The game borrows the Glory Kill mechanic and Ultra-Nightmare difficultynote  of the Brutal Doom mod, and the weapon mod system from Doom, the Roguelike. Argent Energy, Earth's reliance on it as a clean and bountiful source, and the UAC harvesting it leading into the demon invasion is extremely similar to the lore in Hideous Destructor.
  • Attack! Attack! Attack!: The main tactic of the demon hordes... and Doomguy. It works. There is no "conservative" or "defensive" play here. There is no safe place to hide, no holdable position. Standing still will get you killed very quickly.
  • Bad Boss: Olivia Pierce oversees an operation that's dedicated to the sacrifice of its employees and turning over the realms of man to the denizens of Hell. At the end of the game you can find a message from her in which she flat out states that she'll become a god while everyone else will suffer eternal torment in the deepest pit of Hell. It ends with, "Thank you for your service. May you rot in Hell."
  • BFG: The BFG 9000, a massive plasma cannon that fires hyper-charged hell energy and gets used to Glory Kill the Final Boss.
    • Kind of the Trope Namer really. And now in the lore it's explained as seeking out enemies with the charged nature of the plasma and boiling them alive. Which is a nice reference to the fact that apparently on detonation the original BFG sent out trace rays in the engine to target enemies, albeit from the player and in a cone from the direction it was fired.
    • While smaller than The BFG 9000, the Gauss Cannon and Chaingun are no slouches in the firepower department, especially with the Siege Mode and Mobile Turret upgrades respectively. Both slow movement to half speed when their altfire is activated and tear apart demons (and your ammo) within a matter of seconds.
  • Big Bad: Olivia Pierce, a scientist-turned-cultist who believes that having the world engulfed by Hell will lead to the next step in human evolution. In the codex entry "A Farewell", Olivia reveals that she seeks to reach the "real heaven" of Argent D'Nur and be made a god. And everyone else? They can just rot in the deepest pit of Hell for all she cares. She eventually gets her wish, merging with the master of the demons to become the Aranea Imperatix - The Spider Mastermind.
  • Big Good: Samuel Hayden, who extracted the Doomguy from Hell to be the ultimate safeguard against a demonic invasion. Though he's still a Well-Intentioned Extremist who wants to exploit Hell for its resources.
    • It is also implied that God exists in this game, as it is stated in the slayer testaments that Doomguy was endowed with supernatural fighting ability by an angel.
  • Big Red Devil: Imps and Barons of Hell, hell-spawned demons with red skin and horns.
  • The Berserker: The Glory Kill and Berserk artifact mechanics encourage you to run through enemy attacks to rip demons limb from limb.
  • Black Comedy: Not immediately apparent through gameplay, but keep an ear out for the UAC Spokesperson holograms and/or take a read through the Codex sometime. Doom isn't a game one should take seriously.
    • He'll say things along the lines of "Harnessing Hell for a better tomorrow." or "See Jessica in human resources for the Revenant program." Or this gem in later levels about how working at the UAC is meaningful, unlike the rest of your life.
  • Body Armor as Hit Points: Armor in this game acts like bonus health; any damage you take is taken out on armor first.
  • Boom, Headshot: Aiming for the head will deal amplified damage-and cause the enemy's head to pop like a overcooked burrito on death.
    • Or as a loading screen puts it, "If an enemy has a head, it's a weak spot."
  • Boring Yet Practical: The Tactical Scope for the Heavy Assault Rifle and the Gatling Rotor for the Chaingun. Compared to the Micro-Missile Launcher and the Mobile Turret, the former seems rather mundane. However, the scope allows you to use the Assault Rifle as an automatic sniper rifle while the rotor allows you to keep your Chaingun ready to fire at an instant. Both also have a final upgrade that increases their damage when the mods are used, making them extremely powerful to use.
  • Borrowed Biometric Bypass: Several times, you're required to bypass security locks this way. You rip a dead guy's arm off to bypass a fingerprint scanner, and in one case, you take a dead guy's entire torso to get through an optical scanner.
  • Bottomless Magazines: In a return to Doom I and II, your entire ammo reserves are in a single magazine. The "Rich Get Richer" rune will also grant infinite ammo if your armor is above 100 points. The pistol, on the other hand, has infinite ammo by default.
  • Brain Uploading: Samuel Hayden had the healthy parts of his grey matter installed in a robotic body to cheat death after being diagnosed with brain cancer, most notably the frontal and temporal lobes. This meant that he could think creatively and analytically like a human, but could process and calculate information as quickly as a computer.
  • Broad Strokes: The events of Doom, Doom II, and Doom 64 are heavily implied to have happened in something the demons refer to as the "first age", where the Doomguy killed numerous legions of hell. The game also mixes the original Doom and Doom II action gameplay, and a mix of Doom 64 and Doom 3 monster design, UAC base, equipment aesthetics, and storytelling.
  • Brutal Bonus Level: The classic maps, especially on higher difficulty levels. They often have you fighting multiple enemies in tight corridors that make dodging projectiles difficult, with unmodded weapons and limited healing options to boot. Worst of all, there are no checkpoints, so a single mistake can send you back to the very beginning.
  • Bullet Time: With the Saving Throw rune equipped, you get this if you're hit with a blow that would otherwise be lethal, giving you a chance to fight your way out.
  • Call-Back: Trophies include E 1 M 1, IDKFA, Shareware and IPXSETUP.EXE.note 
  • The Cameo: The Icon of Sin shows up in a level late in the game, though it is inactive and does not attack or attempt to stop you. Unless you shoot a rocket into its forehead, which causes it to shoot out a collectible doll and play its speech from Doom II.
  • Canned Orders over Loudspeaker: All over the place in the UAC facilities.
  • Canon Foreigner: Every enemy in the game is a re-interpretation of an enemy from the classic Doom games, plus the shambling zombies from Doom 3. Even the Hell Guards are reminiscent of the Guardian of Hell from Doom 3, though are now exoskeletons controlled by small worm-like creatures rather than the massive crocodile like beast. Olivia Pierce and Samuel Hayden are new characters for the game.
  • Chainsaw Good: The chainsaw returns as a melee option, but its mechanics have changed. It's now a One-Hit Kill on most everything, but it requires fuel units to use. Fuel pickups are relatively rare, and bigger enemies need more fuel to take down. Killing an enemy this way also spawns a lot of ammo.
  • Charged Attack: Most of the weapon mods work like this in some way.
  • The Comically Serious: Samuel Hayden. His frequent exasperation and the seriousness he displays to Doomguy's more 'simple-minded' decisions is a source for some hilarity in the game.
  • The Corruption: Olivia Pierce may have started out with good intentions and sound judgement, but the practices that she began indulging in for the betterment of humanity weren't kind to her. Eventually her aims go from "bettering mankind" to "obtaining godlike power for its own sake". It even shows as by the time you catch up with her at the end before she becomes Spidey, she looks like a zombie, complete with showing signs of grievous injury/necrosis as well as a bad case of Prophet Eyes.
  • Crapsack World: Earth is implied to be this, as it had gone through an major energy crisis prior to the UAC's discovery of Argent Energy, meaning that humanity is solely dependent on the exploitation of Hell itself. Hayden repeatedly warns Doomguy that disrupting the flow of this energy would likely result in a total societal collapse, not that Doomguy pays him any heed.
  • Cult: After succumbing to demonic corruption, Olivia Pierce has turned the UAC into a secretive demon cult.
  • Cyborg:
    • Samuel Hayden, who had part of his brain transplanted into a 3 meter tall robotic body after being diagnosed with inoperable stage 4 brain cancer.
    • Olivia Pierce, to a lesser degree. She's got a titanium exoskeleton grafted to her spine, due to undergoing an experimental procedure to ensure that she wouldn't be permanently bound to a wheelchair after being diagnosed with acute idiopathic scoliosis.
    • Revenants, Cyber-Mancubi, and the Cyberdemon were all cybernetically enhanced by the UAC in their attempts to weaponize Hell. Hell, the Cyberdemon was outright brought back from the dead.
  • Damn You, Muscle Memory!: This game eschews modern mechanics, such as reloading, for a classic feel reminiscent of the first two games. That said, some have been pressing the nonexistent reload button (which actually swaps out weapon mods for your guns) out of pure muscle memory. The classic weapon keybinds have also changed due to removal of fists from your regular arsenal and the new toys you get.
    • On console at least, when you press what would usually be a reload button you instead bring out the chainsaw, which tangentially functions as a reload, and using it on a demon does indeed net you more ammo.
  • Daylight Horror: Unlike in Doom 3 where you faced demons and zombies in darkened rooms this installment is back to facing them in brightly lit areas so that you can see your opponents in all their horrific glory.
  • Deadly Dodging: As with the original Doom, you can anger certain demons into infighting by dodging such that they injure each other as they attempt to target you.
  • Deal with the Devil: This amounts to how the events of the game got started. Olivia Pierce assisted the forces of Hell in crossing over in exchange for a seat in the "new world". Goes without saying it doesn't quite pan out for either party, now that Doomguy is awake. Olivia crosses over into Too Dumb to Live territory by trying to get into Hell to make the demons give what they promised her. She got it in the form of being turned into a ginormous spider-demon, at least before Doomguy blew her brains out with the BFG.
  • Degraded Boss: The Hell Knights compared to their Doom 3 counterparts, they are far more numerous and are typically easier to kill but are still generally competent and last longer than Imps. In the old Doom games, they used to be a somewhat degraded version of the Barons of Hell, just like now.
  • Distaff Counterpart: Olivia Pierce is basically Dr. Betruger with no Y chromosome.
  • Double Jump: Doomguy eventually comes across some thruster boots that let him jump an additional time in the air.
  • Dual Boss: Finished off the first Hell Guard? Don't celebrate just yet, as you immediately face two of them right after.
  • Dragged Off to Hell: Happens quite a few times, though the last few are a deliberate effort so you can break into Hell.
  • The Dreaded: The Doomguy has been elevated to this for the demons. He has already trashed Hell once, and was only stopped by dropping an entire temple on him. The demons fear him and regard him as the biggest threat to their goal after he awakens and breaks free at the start of the game. The demons feared him so much that upon successfully entombing him, they covered the entire site with runes to prevent anything going in/out and heavily protected the site. When the UAC discovered the tomb and retrieved the Doomguy, they noted that the demons fought with levels of desperate ferocity that they had never seen before.
  • Dramatic Gun Cock: Doomguy pumps his shotgun right as he's about to get off the elevator once the first mission, following the title screen.
  • Dropped a Bridge on Him: Or in the Doom Slayer's case, a temple. It doesn't take.
  • Early-Bird Cameo: The Heavy Machine Gun appeared in the Steam version of Quake Live.
  • Electronic Speech Impediment: VEGA, as you're shutting it down in the second-to-last level.
  • Elite Mooks: The UAC's red-armored Elite Guard (whose armor can be earned in multiplayer) were elite troops cybernetically enhanced by their Powered Armor suits. However, this made them dangerous enough that Hayden had a Self-Destruct Mechanism installed into their suits so they could be dealt with in case of insurrection. Too bad for him, he gave the self-destruct codes to Olivia as well, and she presumably used it to kill them all when she sided with the demons and started the invasion. In the campaign, all they're good for is scavenging their bodies for chips to upgrade your Praetor Suit. Interestingly, these are the chips that were installed as a kill-switch.
    • In bits of the lore it's said they're authority was absolute, answering only to the highest ranking UAC members, so Authority Equals Asskicking, apparently.
  • Emergency Weapon: Two: the Chainsaw for a spray of ammo and health, though different enemy sizes require more fuel; and the BFG 9000, which can kill everything in one hit, short of a boss. Each has its own specific ammo pickup.
    • The chainsaw requires one fuel unit for most small enemies (imps, possessed soldiers and the like), three for bigger ones like the Revenant and Hell Knight, four for Pinkies, and five for Mancubi and the Barons. Its ammo pool is upgraded with your suit's Argent cells. And as mentioned, it makes your enemies drop a ton of ammo pickups.
    • The BFG however only has three shots, though ammo can be relatively plentiful in big arenas. It's also good to use against bosses as it takes off about a tenth of their healthbar and stuns them, leaving them open to other weapons which will drop health.
    • The Pistol, a peashooter whose main perk is never running out of ammo, but it also has an upgradeable charge shot so you're not completely boned if you have to rely on it.
  • Establishing Character Moment: The Doomguy awakens naked and handcuffed to a slab and surrounded by possessed zombies, and when he has one hand free, grabs one of the zombies and smashes its head into the slab before grabbing a pistol and killing the rest. When Samuel attempts to greet him, he throws the monitor into the wall. And when he does so again, stating that what they were doing was for all mankind, Doomguy takes a very deliberate glance at the mutilated corpse at his feet before smashing the speaker in.
    • He keeps doing it despite pleas to not destroy the Argent filters, kicking them to beyond repair. And Samuel finally gives up, and Doomguy keeps smashing.
    • But he does seem to have a softer side, in that he created a backup of VEGA before destroying him due to the fact they needed the energy to open another portal.
  • Even Evil Has Standards: The demons may be evil but their writings indicate a loathing of betrayers, referring to them as "wretched".
  • Everything Fades: Demon corpses and gibs disintegrate after a few seconds. As with Doom 3, this was likely meant to ease up on memory.
  • Evil Brit: Olivia Pierce has an English accent, and is the game's Big Bad.
  • Evil, Inc.: The UAC is considerably more unscrupulous and amoral compared to its previous incarnations in the series. From trying to use Hell as a place for resource extraction, to capturing live demons to turn into cybernetic weapons, along with the practically cult-like indoctrination of its employees as seen in the pre-recorded holograms throughout the facility.
  • Evil Is Visceral: Most enemies look like zombies with parts missing or mashed together, the various demons in particular look incredibly thin and coated in blood, often even like their skin was flayed off.
  • Evil Sounds Deep: The various demonic voices, naturally. A more morally ambiguous version with Samuel Hayden, whose deep synthesized voice growls and distorts menacingly. In comparison, VEGA's voice is equally synthetic but is at a far more natural, human register.
  • Evil Versus Evil: While it's not terribly common due to Set a Mook to Kill a Mook being mostly averted for the game, there are a few times when you can glimpse demons battling each other before they notice you. This includes a Revenant fighting a Mancubus over an island, a Mancubus scorching some Possessed and a Baron of Hell using some Imps as target practice for his energy blasts. The only time the player can instigate this is between Hell Knights and Imps, who are the only demons who may attack each other in combat. While demons can still put others into a Glory Kill state if they hit each other, they only care about pounding the Doom Slayer's face in during a fight.
  • Exact Words: The Deal with the Devil that frames the story's start.
    • For Olivia Pierce, she wanted power, and was painfully transfigured into the Spider Mastermind.
    • It applies to the backstory, too. The Betrayer of Argent D'Nur wanted his son revived, and he was... as the Icon of Sin.
  • Excuse Plot: Subverted. It initially seems this way - questions like "Why are you in a sarcophagus?" and "Why are there demons?" appear to have little answer beyond "Do you want to play Doom or not?", but closer examination reveals a trove of surprisingly rich and detailed lore hidden in audio logs and database entries.
  • Exploding Barrels: All over the place, and they're colored red too. The acid barrel sprites appear in the classically-styled areas and maps.
  • Explosive Decompression: Downplayed. The UAC facilities are generally kept at a higher pressure than the Martian surface is, and when cycling an airlock open the pressure difference will blow loose objects toward the outer door, but only if they are light, and not at a very far distance at that. Apparently the airlocks' pressure-matching systems are not functioning well...
  • Explosive Leash: In the Codex, it is revealed that the Elite Guard (the red guys you get suit upgrades from) are all implanted with "kill chips" to curb their absolute authority in the facility. In case of mutiny, only Samuel Hayden and Olivia Pierce can activate them... which would explain why all these supposedly ultra-badass enforcers are dead by the time you show up.
  • Expy:
    • Olivia Pierce is one to Malcolm Betruger.
    • The Summoner enemy is the Arch-Vile in all but name.
      • Further proving the point, its model name, as seen in the Resources Explorer, is "archvile".
  • Eye Scream: A few of the glory kills involve eye mutilation. A few examples would be shoving a Pinky demon's horn into one of its eyes, or crushing/tearing the Cacodemon's eye with your bare fist or chainsaw.
  • Face–Heel Turn: One of the knights of ancient world of Argent D'nur betrayed his people to the forces of Hell for the promise of bringing his dead son back to life, leading to the world being absorbed into hell and creating the Argent Energy everyone's after.
  • Fate Worse Than Death: The Revenants, which are created through a horrifying combination of flaying, torturing, and exposing a live human being to Lazarus Waves till they become undead killing machines.
    • The Wraiths, which lie within the Argent D'nur, were originally noble beings protected by the Night Sentinels and Hell sought to absorb their world so they can gain the limitless power they possess and expand Hell exponentially with the Argent Energy's potential. Well, Hell succeeded and now they are corrupted, trapped in a permanent torment just to be used for the forces of Hell's endless conquest.
  • Featureless Protagonist: The Doom Guy has no name nor dialogue just as before. It's not even clear if he's human or just looks human. However, this doesn't detract from him having a personality of his own.
  • Filk Song: Hell To Pay, head-bangingly provided by Miracle of Sound
  • Final Boss: Olivia Pierce, who transforms into the Spider Mastermind, is the final enemy you face in the game.
  • Final Death: Playing on Ultra-Nightmare means that you only have one life. If you die, it's back to the beginning.
  • Finishing Move: The "Glory Kill" mechanic allows the Doom Slayer to perform these on staggered enemies. And it's not just for show; Glory Killing an enemy guarantees that it'll drop health pickups on death. Enemies can also do this to the Doomguy, should he be killed by certain attacks. Glory Kills are the only way to finish off the bosses; if you don't Glory Kill them, they will regain some health and continue the devastating fight.
  • Full-Frontal Assault: Doom Guy starts the game completely naked and Strapped to an Operating Table before breaking out of his chains with his bare hands, picking up a gun, and shooting a bunch of demons before he can even find any clothes.
  • Game-Breaking Bug: Some players have reported accidentally activating Developer Mode, which corrupts saves and disables achievements or multiplayer.
    • There's another bug where all NPC audio goes away. The game is surprisingly coherant without it.
  • Genius Bruiser: Dr. Hayden is one of the greatest scientific minds of his time. He's also a 10-foot tall robot with superhuman strength and energy shielding, powered by a mini-reactor that's exponentially more powerful than a fusion power plant, who personally lead an expedition into Hell to retrieve the Doom Marine from his tomb.
  • Genre Throwback: Way back to original Doom and the first generation of first-person shooters. Kill anything that moves, worry about the plot later.
    • Huge maps, with a dedicated map-screen. Key hunting, the option to remove objective markers, boss health bars, etc. No reloads, circle strafing, carry a massive arsenal. Oh yeah, it's a throwback with kickass visuals and high quality graphics and production.
  • Glass Cannon: The Doomguy can mow down enemies like no one's business, but his health doesn't regenerate and especially on Nightmare, he cannot take much damage.
  • Godzilla Threshold: The demonic invasion is the point at which Samuel releases the Doomguy to contain it. Samuel is unhappy that Doomguy wrecks everything in his path, but has little other choice given the circumstances. Later on, Samuel resorts to other drastic measures, like shutting down VEGA in order to re-route the power to let Doomguy stop the invasion once and for all. Also invoked in the opening loading screen:
    Corrax Entry 7:17: So you walk eternally through the shadow realms, standing against evil where all others falter. May your thirst for retribution never quench, may the blood on your sword never dry, and may we never need you again.
  • Gone Horribly Right: The researchers attempted to give the Cyberdemon an Argent Energy generator to help it automatically recover any damage done to it's body. Unfortunately once the system was activated the first thing it regenerated was the frontal lobes of the brain the researchers had surgically detached to keep it unconscious.
  • Good Scars, Evil Scars: When Doomguy is breaking free at the beginning, it's shown that his hands and arms are covered in hairline scars. Someone even branded his left palm, possibly himself. Demons and zombies on the other hand have horrific, giant scars all over their bodies.
  • Gorn: This game does not shy away from gruesome and bloody violence as used by both the Doomguy and the forces of Hell.
  • Greater-Scope Villain: The unseen Lord of Hell, who is the one who made a deal with Olivia Pierce to open the Hell Portal and start the demonic invasion. at the end, it merged with her and becomes the Spider Mastermind.
  • Grievous Harm with a Body: The Doomguy can rip off the limbs of demons and use them against them in some glory kills or the demons can do the same to him when he is killed such as the Imp, Revenant, and Baron of Hell.
  • Gun Nut: At one point, Samuel Hayden notes that Doomguy seems to have an affinity for guns.
  • Half the Man He Used to Be: This is often the result of using the Chainsaw on a demon. Doomguy himself can also suffer this fate if he is killed by a Summoner's energy wave or a Hell Razer's beam, just to name a couple of examples.
  • Harder Than Hard: Ultra-Nightmare, in addition to being as viciously tough as Nightmare, gives you only one life. If you die, you have to start from the beginning.
  • Have a Nice Death: There are a number of special death animations depending on who or what kills you. A few enemies, such as the Revenant, can even tear you apart in a method not unlike the Glory Kill.
  • Heavily Armored Mook: Mancubus and Pinky monsters now have armor covering their bodies, protecting them from any hits on those parts.
  • Heel–Face Turn:
  • Hell Is That Noise: Literally. You can usually tell there are demons nearby from the incessant hiss/moan/growl noise the Possessed emit.
    • Also invoked in the game's soundtrack. Composer Mick Gordon stated in several interviews that a lot of the synth sounds in the game were inspired by the concept art depicting raw Argent Energy, so he tried to create an audio representation of said energy. What he came up with was breaking sound down into it's most basic forms (sine waves and noise), then running those played frequencies through a huge rack of analog compressors and distortion units to corrupt the sound into a Hellish, unrecognizable form.
  • Hell on Earth: Demons are invading from Hell into our universe through a rip in reality on Mars.
  • He Who Fights Monsters: The Doomguy has apparently been changed by his journey(s) to hell and exposure to demonic energies. The first thing he does upon waking is rip his way out of thick iron chains and crush a zombie's head with his hand. His armor now bears strange runes, and can only be worn and activated by him. And, in addition to being hyper-violent, he can absorb demonic energies and runes that lore indicates would kill or cripple a normal human. Which, clearly, they no longer are.
  • Hidden Depths: While Doomguy's standard mode of operation is "rip and tear", he's not as much of a rampaging berserker as he might otherwise seem. He hesitates before he starts destroying the Argent Plasma filters, hinting that he might regret dooming humanity's energy production, and he takes time to backup VEGA despite having no reason to do so. He may be absolutely dedicated to killing all demons and destroying Hell, but, especially in his interactions with other people, he shows that he is capable of rational thought and careful consideration.
  • Hidden Villain: The current ruler of Hell: the as-of-yet unnamed dark lord of the fourth age. He is never seen, although he is mentioned in the data logs and at a few points in the campaign his voice is heard.
  • Horrifying the Horror: Later in the game, it's revealed that the demons are absolutely terrified of Doomguy, seeing him as an unstoppable fighting machine who they struggled to seal away.
  • Human Sacrifice: As they fall to Hell's corruption, the UAC start performing human sacrifices in their research in Argent Energy. Don't worry, it was entirely voluntary on the sacrifices' part.
  • Hyperspace Arsenal: In deliberate defiance of modern (at the time of release) FPS conventions, Doomguy can carry every single gun at once. In fact, the player will often go through the entirety of their gigantic arsenal in a single battle, swapping out one weapon for the next depending on the situation (and ammo count).
  • I Cannot Self-Terminate: VEGA says this when you're going towards his core to shut him down. Therefore, he helps you with the process.
  • Idiosyncratic Difficulty Levels: There's five difficulty levels. The first four are playable from the start, but Ultra-Nightmare is unlocked after completing the fifth mission in the single player campaign.
  • Interface Screw: Cacodemon ranged attacks temporarily blur the entire screen. The data logs reveal it's a narcotic bile, meant to intoxicate prey so it can eat them.
  • I Was Quite The Looker: There's a photo of Olivia Pierce in the UAC's "hall of most valued employees" in the complex's main HQ. She looks significantly healthier and more attractive than her current "female Mr. Burns" appearance. The photo's not even that old, either, as it lists her as "Director of the Lazarus Project". It seems the constant pain from her exoskeleton and dealing with occult powers really took a toll on her, even before she opened the hell portal and started slowly turning into a living corpse.
  • Jawbreaker: Just one of the many Glory Kills you can perform.
  • Jump Physics: Normally, you have very little air control when you jump. However, you can get a rune that allows you to have greater midair movement with your double jump. Upgrading the rune allows that enhanced movement to also apply to single jumps.
  • Large and in Charge: Zigzagged with Samuel Hayden, his robotic body eclipses the Doomguy in size and stands higher than a Hell Knight, but he isn't interested in picking a fight directly. That said, it does however take some balls to willingly lead a charge through Hell itself to rescue the Doomguy from his tomb to begin with. In the codex it is said that he used his 3 meters tall body to pull a 12 foot lever to start the argent flow, almost as a show of symbolic power...and yet when he was questioned about the size of his robotic body he answered that you never know when you might need a hero.
  • Kill Enemies to Open: The demonic presence has a lot of areas placed under lockdown, so they need to be cleared of demons in order to advance.
  • Laser Blade: You are told at one point that Doomguy once had a sword. Your dear friend Samuel Hayden revealed it to have been the Crucible all along, and has pretty much stole it from you. Doubles as a Cool Sword.
  • Last Chance Hit Point: If you have the Saving Throw rune equipped, a hit that would normally kill instead leaves you at 5 health and gives you a brief period of Bullet Time to escape your predicament.
  • Leaning on the Fourth Wall: You're either playing as the Sole Survivor of an ancient land invaded by Hell who swore eternal vengeance on the demons, or the Player Character of Doom and Doom II who became such a Memetic Badass over those games he's now some sort of everlasting vengeance god.
  • Le Parkour: The Doomguy is surprisingly agile, able to grip onto ledges to find secrets and hidden powerups.
  • Level Editor: The game lets you create SnapMaps that can be shared online.
  • Life Drain: The Siphon Grenade steals health from enemies in the blast radius and gives it back to the Doomguy.
  • Lighter and Softer: While the game is still a bloodbath, it puts far less focus on horror and tension than Doom 3, and takes its story far less seriously than than Doom 3.
  • Ludicrous Gibs: A lot of the enemies can be easily gibbed. Enjoy a HELL of a bloodbath!
  • MacGuffin: The Crucible.
  • Macross Missile Massacre:
    • The Micro Missile mod for the Heavy Assault Rifle lets you fire six micro-sized missiles at a time.
      • With the Rich get Richer rune, full armor and fully upgraded mod the heavy AR can launch infinite missiles without pausing or reloading.
    • The Rocket Launcher has the Lock-on Burst mod, which fires three rockets at the locked target.
    • Revenants can fire a missile barrage with their MLRB implants, rather than the two-at-a-time from the original Doom games.
    • The Cyberdemon now has a MLRB system implanted in it's back. The grafted launcher in its left arm can launch a hefty salvo as well, one at a time.
  • Mad Scientist: Olivia Pierce. Samuel Hayden has shades of this, as while he is far more morally sound, he still considers it a good idea to deal in Hell energy despite the problems caused as a result of it falling into the wrong hands.
  • Mascot Mook: While the Cacodemon has held this honor for previous Doom games, the Revenant seems to take the spot for this installment, being featured in the most promotional art and even having getting its own statue in the special edition.
  • Minimalist Cast: Besides the Silent Protagonist player character, the game's only real characters are your ally Samuel Hayden and main antagonist Olivia Pierce. You also receive the occasional messages from VEGA, the base's A.I., and various creepy pre-recorded corporate propaganda messages from a UAC Spokesman.
  • Monster-Shaped Mountain: The Titan region in Hell is named after the giant, skeletal remains from Hell's greatest champion littering the landscape, having been done in by the Doomguy at some point before the game.
  • Mook Horror Show: Downplayed with the Slayer's Testimonial, which recount the Doomslayer's unstoppable slaughter of Hell's demons. To humans it's a victory against the dark, to the demons it was one of the most terrifying disasters in history.
    • Using glory kills and the chainsaw can give players a momentary glimpse into the fear the demons have before getting slaughtered. Using the chainsaw on one in particular has the victim throw their arms across each other in a vain attempt to block the incoming attack.
  • Mythology Gag: Many.
    • Several from Doom 3: One of the fingerprint scanners you have to use requires Z-Sec clearance, and you can find the (sadly unusable) Soul Cube in Olivia's office. You can also find a playable Super Turbo Turkey Puncher 3 arcade cabinet. One of the flavor texts is a straight reference to a PDA message that specifies the exact details for a demonic ritual.
    • Logos for the Mixom corporation pop up on some equipment. In Doom 3, Mixom is the manufacturer of the chainsaws, and accidentally ships several to Mars.
    • The illustration on Samuel's desk of the Doomguy fighting ancient demons has them drawn very similarly to how they looked in the original game's cover art.
    • The doors in the foundry level make the classic Doom Doors sounds, and several of the doors in both Mars and Hell are visually based off of the original game's door textures.
    • Later in the game while in Hell, there's an arena based off the "Dead Simple" level in Doom II, and the "Barrels O' Fun" level gets a nod by being the name of a suit upgrade.
    • The BFG-9000's visual design heavily resembles its appearance in the Doom film.
    • The Doom II manual states that the Spider Mastermind isn't equipped with a plasma gun, and thank god for that. Guess what Spidey has in this game.
    • The theme for the game that plays in both the opening and the ending, as well as part of various tracks, is a very heavy synthetic remix of the iconic 'E1M1' song from the first Doom. The ambient music that plays after returning to the destroyed Argent facility sounds much like the opening notes of 'E1M2' as well.
    • A lot of thought went into the musical cues for this game. For example, BFG Division contains a segment of the main riff from the original game's Waltz Of The Demons (E2M7) in glorious heavy metal (around 2:38). Likewise, the Argent Facility combat music (prior to going to Hell) is a heavily remixed version of the main menu theme of Doom 3, and the music that plays when you first see Olivia Pierce in person is a remix of Suspense (E1M5) from the first game. The track that plays over the main menu, HellWalker, is a remix of several songs from the first two games.
    • The achievement obtained by upgrading and fully mastering all your weapons is called simply IDKFA, the original doom all weapons/ammo cheat code.
    • One of the datapads the player can find instructs employees to fill out a "WAD-E1M4" form to turn in to their Command Controller. This refers to the naming convention of level data files in the original Doom (specifically Episode 1, Mission 4, called Command Control) and the .WAD file format.
  • Names to Run Away from Really Fast: The forces of Hell, who collectively call themselves "The Slaves of Doom" are so terrified of the Doomguy they all know him as "the Doom Slayer."
  • Neck Snap: Doomguy does this on several Glory Kills. The game doesn't shy away from providing some appropiate sound effects.
  • Nintendo Hard: This game returns to the furious run n' gun gameplay style of the classic DOOM series, lacking conventions present in many other shooters released in its era such Regenerating Health and cover mechanics. As such, constantly staying on the move and keeping aware of enemies and obstacles at all times is essential to getting through the levels. Even the easier difficulty settings are no cakewalk, and "camping" is the best possible strategy for getting yourself utterly curb-stomped by the enemy.
  • N.G.O. Superpower: The UAC is a large, powerful corporation with its own private army and access to technology that nobody else does. Earth and the other Solar System colonies are completely dependent on the Argent Energy produced by the UAC Mars facility. The UAC has also been putting cybernetic attachments on the Revenants, Mancubi, and Cyberdemon to turn them into living weapons.
  • No Fair Cheating: This game provides a horrific (and possibly unintentional) example; entering any cheat through the console automatically enables "Development Mode" which not only disables Steam achievements but also prevents you from playing Multiplayer or creating Snapmaps. The true kicker though is that the only to turn Development Mode off is to completely wipe your save files. Thus far, Bethesda have not produced a patch to fix this.
  • No-Sell: If you try to shoot Dr. Hayden upon meeting him face-to-face, your projectiles will dissolve harmlessly against some sort of personal energy shield, and he'll simply tell you to "save your ammunition". His tone isn't even annoyed, just matter-of-fact.
  • Nostalgia Level: A few examples.
    • Every level has an area using the textures and maps of the original two games, which unlocks said levels in full from the menu.
    • The Icon of Sin makes a reappearance, still dead as a doornail.
    • One of the levels in Hell features an adaptation of Dead Simple.
  • Obviously Evil: The UAC isn't even trying to hide its cultish side. Various documents you find and the recorded spokesperson speeches freely talk about things like chanting, sacrifices, magi, and exploiting hell.
  • One-Hit KO: The chainsaw now takes down anything in one hit, but it takes fuel to do it. Naturally, it doesn't work against bosses.
  • One-Hit-Point Wonder: One Rune Challenge pits you against various demons from zombie and imp to Hell Knight and Pinky, with nothing but a shotgun and 1 hp, and no health pickups even dropped from glory kills, forcing you to rely on armor to survive.
  • One-Word Title
  • Pet the Dog: With how violent the Doomguy can be and how frequently he destroys expensive equipment for the hell of it, it's surprising that he gets a moment of compassion when he decides to back up VEGA despite no compulsion to do so when he's told to destroy his core to enter the Well.
    • On picking up the Classic Guy collectible, the Doomguy adjusts its arm and stops to give its tiny fist a brotherly bump.
  • Post Peak Oil: Mankind hasn't just run out of oil, they've started running out of uranium and plutonium too. This gives context to Hayden's insistence that humanity needs Hell's argent energy to survive.
  • Powered Armor: Doomguy's Praetor Suit, which according to the Slayer Testaments, was created/improved by a demon who betrayed Hell and sided with him.
  • Quad Damage: Makes its Doom debut after being a staple item in id's Quake, and shows up in both single-player and multiplayer.
  • Rated M for Manly: Oh HELL YES! Between the blood, the gore, the Glory Kills and the one-man onslaught against The Legions of Hell, DOOM is all about being a badass.
  • Reconstruction: After the deconstructive Doom 3 - where it shows you just how terrifying it would be being a lone marine, trapped on Mars, with monsters teleporting from nightmare world - this game brings the series back to its roots; running, gunning, ripping, and tearing your way through The Legions of Hell with all the guns and chainsaws you can carry, and how terrifying it would be for the demons if you were successfully smashing through their ranks.
  • Retraux: Hidden rooms in the campaign use layouts, textures, and sprites of the first two Doom games and entering them unlocks the full, similarly-styled level.
  • Revisiting the Roots: After Doom 3, which was more of a survival-horror, this Doom returns to the fast-paced action of the classics with some updated polish and new tricks up its sleeves.
  • Rewarded as a Traitor Deserves: Argent D'nur fell to the demons when one of its defenders betrayed them in exchange for his son being revived. The demons kept their bargain by reviving him as a demon because "the wages of treachery are suffering".
  • Roaring Rampage of Revenge: What the Doomguy's motivation for fighting against Hell is hinted to be. Codex entries and The Slayer's Testament imply he belonged to an order called the Night Sentinels, the protectors of Argent D'nur. They successfully resisted all invasion attempts by Hell until a member of the Night Sentinels betrayed the order and allowed Hell to absorb the entire realm. The Doomguy was the last one alive, and dedicated his life to the destruction of Hell as retribution.
  • Rocket Jump: You can get a boost for your jumps by using the Gauss Cannon's recoil to get a little more airtime.
  • Rocket Tag Gameplay: As the Doomguy is less durable but harder-hitting, much of the gameplay involves rapidly chasing down demons and killing them quickly, while scooping up health and ammo and avoiding being killed by their damaging attacks. This is particularly evident on the higher difficulties where stronger demons can easily kill you in a couple solid hits.
  • Save Scumming: Every action you take that counts towards a level challenge or weapon/rune upgrade is saved the moment you perform it and doesn't reset with a death, reload or exit to the main menu.
  • Scenery Gorn: The effects of an invasion from Hell into our world are immediately obvious and quite visceral. Every area that has been corrupted by demons is either soaked in blood, decorated with violently mutilated human remains, or on fire. Usually all three.
  • Scenery Porn: The environments and landscapes that appear throughout the game are stunning. The first times you see Mars and Hell in all of their glory are sure to leave one hell of an impression.
  • Sealed Good in a Can: The Doomguy. The demons call him the Doom Slayer as he ran riot across Hell after the fall of Argent D'nur, only being stopped when he was led into a trap and entombed. He's discovered by the UAC and hidden away by Samuel Hayden, who believes him to be the only person capable of stopping a invasion should one happen. He's right.
  • Secondary Fire: Some weapon mods give secondary firing modes, like an explosive shot for the shotgun or mini-missiles for the heavy assault rifle.
  • Secret Level: Thirteen of them, all recreations of classic Doom and Doom II levels, which can be unlocked after finding the appropriate hidden rooms throughout the campaign.
  • Self-Imposed Challenge: This guy beats Ultra-Nightmare using only the pistol.
  • Sequel Hook:
  • Set a Mook to Kill a Mook: Much like Doom and Doom II, the player can instigate monster infighting by causing them to hit each other in the midst of combat. There's also a number of scripted sequences that involve enemies already attacking each other, which the player can interrupt or let them weaken each other first.
  • Shield-Bearing Mook: Possessed Security have large shields that defend them from frontal attacks.
  • Shout-Out:
    • As with the original, one of the difficulty settings is "Ultra-Violence".
    • If you die by falling into a lava pit, the Doom Marine will give a Terminator-esque thumbs up.
    • The illustration that you can find on Samuel Hayden's desk of the Doomguy fighting demons is in the style of the Ark of the Covenant's woodcut illustration in Raiders of the Lost Ark.
    • The Pistol and BFG-9000 act very similarly to Quake II's Blaster and BFG 10K, respectively. The Pistol's visual design also resembles the Dominator pistol from Psycho-Pass.
    • Just as in Quake III: Arena, picking up extra armor that surpasses your default meter will decay over time.
    • One of the multiplayer taunts is Carlton's dance.
    • In one of the Hell levels, it's possible to find a skeleton with a horned helmet and an arrow through its knee.
    • One of the Hell levels also has the helmet of Commander Keen, and the Dopefish shows up on various noodle containers laying around the UAC base. There's also a Marineguy figure painted to look like Commander Keen himself.
    • A door early on in the game has a Vault-Tec logo on it.
    • An early collectible is "Vaultguy", Doomguy with his armor painted like a Vault suit.
    • The demons Apocalyptic Log is titled the Slayer Testament.
    • The description for the Hologram in the Codex as much as says it was designed to mimic the effects of the Holoduke in Duke Nukem 3D.
  • Shows Damage: Some enemies can have limbs blown off without actually being killed. Olivia Pierce as the Spider Mastermind becomes increasingly bruised and has greater trouble moving as you damage her. A bit of an exaggeration of the normal situation in that by the end of the fight, she's just flailing lasers and limbs that can no longer support her weight at you in an attempt to get you to relent.
  • Suspicious Video Game Generosity: If you run into a large pile of ammo, health, and armor, you can expect a boss fight to follow shortly.
    • When destroying the cooling systems, or in other big arenas, there will be a surprising amount of BFG ammo laying around, enough to refill its entire pool of three shots.
    • Most of the final level is non-stop ammo resupplies, especially around the corpses of the Argent skeletons.
  • Static Role, Exchangeable Character: As with Stealth Sequel, it's made ambiguous as to what this game's Doomguy is. The Slayer's Testaments are ambiguous as to whether he was the leading knight of a separate dimension known as Argent D'nur, or the Doomguy from the original games, or even Doom 3 - several documents around the UAC facilities make it clear several dimensions are connected to Hell, and the logs regarding the Doomguy note he was equipped with UAC armor. The Slayer's Testament also notes he was the one who slew someone very important to the demons - either the Icon of Sin from Doom 2, or Betreuger from Doom 3.
  • Stealth Sequel: It's implied that the Doomguy in this game is actually the very same one from the original two Doom games.
  • Stylistic Suck: The "Classic" maps have blocky textures, almost no shading effects, 2-dimensional sprites for gore and pickups, and cheesy speed metal MIDI solos playing throughout, to emulate the feel of the first two Doom games. In fact, the classic maps are even worse in appearance than in the original games. The light levels are all static instead of varying from sector to sector like, and texture misalignment is ubiquitous (though the originals had occasional, but far fewer, instances where the wall textures weren't aligned cleanly).
  • Tranquil Fury: How else can you describe a man who carves through the forces of hell without uttering a word.
  • Turned Against Their Masters: The Revenants, Mancubi, and Cyberdemon were all created by the UAC to be used as weapons. Being Too Dumb to Live, they seem to have engaged in mass production before even having figured out a way to control the damn things.
  • "The Reason You Suck" Speech: Samuel Hayden lashes out on the Doomguy for his tendency to blow up everything as the sole solution to the Hell disaster, which he says costed the unlimited energy source that could have been used to solve the energy crisis back on Earth.
  • The Unfought: Samuel Hayden.
    Samuel Hayden: I am not the villain in this story. I do what I do because there is no choice.
  • Teeth-Clenched Teamwork: Doomguy clearly has no patience with Hayden's expositing ways while Hayden finds Doomguy's habit of smashing things to be incredibly frustrating. Nevertheless, the two need each other's help to stop the invasion from hell.
  • Title Drop: The demons call Hell "Doom", with their collective forces the "Slaves of Doom", and the Doomguy himself known as "the Doom Slayer". Really, the word "doom" is all over the place in this game.
  • Took a Level in Badass: A number of returning enemies from the past games are significantly faster and more aggressive than before, and have new attacks and capabilities.
    • The basic Imp is now capable of chucking fireballs while running in any direction, will lead moving targets, and has pinpoint accuracy. It is also capable of navigating the environment with startling agility, and will cling to pipes and walls to rain fireballs down. They also have a charged up massive fireball which can wipe you of all your health in the higher difficulties.
    • The Possessed Security, this game's version of the Shotgunner, has received a significant buff as it is the only hitscan enemy in the game now, and is equipped with a riot shield that deflects bullets back at the player.
    • Pinkies now sport chitinous armor that resists most attacks from the front, and will charge at the player with impressive speed, while having enough agility to track the player's direction mid-charge.
    • After being absent in Doom 3, the Baron of Hell is back and is far quicker than before, capable of keeping pace with the player and making great leaps to close the distance, as well as having a number of powerful melee attacks on top of its green fireball attack.
    • The Cacodemon's spit now causes your vision to blur for a brief moment should you be hit, and they will constantly advanced on the player to use their bite attack once in range.
    • The Revenants, which in the originals were more of a Glass Cannon that gradually became passé as time went on, got a pretty significant buff that turns them into Lightning Bruisers with the bonus of being able to fly and smoke you out with a shit load of missiles.
    • The Mancubus now has a number of means to stop players from circlestrafing it at close range, including a ground pound move that repels anyone who gets too close. Taken even further with its much more powerful and durable variation: The Cyber-Mancubus!
    • The Summoner, effectively a renamed Arch-Vile, retains many of the abilities it had in Doom 3 but is much more mobile, teleporting around the area and never staying in one place for more than a few seconds.
    • The Cyberdemon as well, even though its lost his Damage Sponge status, its far more competent as an opponent and, despite its size, is frighteningly fast, forcing you to keep on your toes or be in for a world of hurt. Not only does it keep the rapid fire rocket launcher, it can launch a swarm of missiles, charge across the map, create a forced corridor, throw sword beams, and has a lock on beam that tracks your movement. On top of being able to stomp on you if you get too close. But unlike Doom 3, it can be weakened by normal weapons instead of the Soul Cube.
    • The Spider Mastermind. Rather than the weak end-boss she was back then, this one puts up far more of a fight than she did in the original, being much more durable and packing a number of different weapons, including a plasma chaingun, lasers and mines.
  • Tranquil Fury: Doomguy never speaks, but still turns the forces of hell to Ludicrous Gibs. Also seen with Samuel Hayden, where he regularly destroys Hayden's means of communication but never directly attacks the head of the UAC.
  • Turns Red: Inverted with the Spider Mastermind, which becomes increasingly bruised and crippled after a considerable number of hits are landed on it.
  • Unobtainium: The Argent energy used to power everything drives a portion of the story, being from Hell itself and all.
  • Unstoppable Rage: The Doom Slayer has this as his ruling emotion when it comes to demons and anything related to them, as the lengthy killing spree in Hell before the game as well as his demeanour towards any demon in the present day showcases very clearly.
  • Up to Eleven: VEGA supercomputer can reach temperatures 173 hotter than the surface of the Sun, and has to be cooled down with the world-first absolute zero cooling system.
  • Utopia Justifies the Means: Samuel Hayden believes that opening a portal to Hell, a good chunk of the UAC becoming Luciferians (including his protege, Olivia Pierce), and the UAC facility's subsequent slaughter by the demons was all acceptable losses in exchange for a clean, bountiful energy source.
    Samuel Hayden: Our interest in their world was purely for the betterment of mankind. Everything has clearly gotten out of hand, yes, but I assure you, it was worth the risk.
  • Video Game Cruelty Potential: Taking numerous pages from Brutal Doom, the game has Glory Kills, which enable the player to violently finish off a weakened enemy, and performing one give the player health. Additionally, several Runes encourage the player to perform these to gain its benefits.
  • Wave Motion Gun: The Siege Mode of the Gauss Rifle. It requires the firer to be stationary, has a lengthy charge up time, and will kill virtually all enemies within 2 shots, as well as any enemies near the path of the beam. Upgrades shorten the firing time and let you move slowly with it.
  • We Can Rebuild Him: The Cyberdemon is the result of the UAC finding the remains of a powerful demon lord in Hell, doing experiments on them with Argent Energy, and then deciding to cybernetically enhance the result.
  • Well-Intentioned Extremist:
    • Both Olivia Pierce and Samuel Hayden, the former working with Hell to bring about a new world for mankind and the latter wanting to utilize Hell for its resources to usher in a better world for mankind as well. Although in Olivia's case it eventually degenerates into "Obtain God-like power".
    • Doomguy fits this, considering that his world was destroyed by The Legions of Hell, it seems justifiable in wiping out every last trace of it when he reawakens to try and stop Earth from suffering the same fate.
  • What the Hell, Hero?: Samuel Hayden gets really annoyed at Doomguy smashing up the energy conduits rather than carefully removing the power source, chastising him on the importance of hell power and how they'll be facing an energy crisis thanks to him.
  • When All You Have Is a Hammer...: Doomguy solves every problem he encounters by punching the shit out of it. Find an upgrade bot? Punch the shit out of it. Ammo cache? Punch the shit out of it. Fragile, highly-valuable energy conduits powering a tower of doom? Kick the shit out of it.
  • World of Badass: The main character is an immortal butcher machine. The Corrupt Corporate Executive is a 3-meter tall robot. The imps have cheetah-speed agility and the pinpoint accuracy to match. The AI uses terrawatts of electricity and can accurately calculate how to create portals from HELL ITSELF to Mars and back. The Hell Knights are relentless giant apes that are only eclipsed by Hell Barons. The hellboar "pinkies" have anti-rocket armor and sometimes psychic stealth camoflage. The Cyberdemon can now trap the player in a corridor and spam rockets/sword beams. There's a worm that can power and pilot a murdergolem - no wait, there's three. The crippled old lady turns into a giant robot spider with all the upgrades that should have been tacked on to the original Final Boss of Doom 2. Even the pathetic zombies can eat straight through Hellforged Power Armor. Everyone else has GUNS grafted to their arms and/or mouths.
  • Worthy Opponent: Implied by the Slayer's Testament to be how the demons perceive the Doom Marine. The testament speaks unflinchingly about how thoroughly he terrorized demonkind, lionizing his destructive prowess despite it being directed against them, in a tone of respect or even admiration. There's no indication of whether these sentiments are mutual, however.

Alternative Title(s): Doom 4
