''Doom'' is the 5th (''Doom'', ''Doom 2'', ''Doom 64'', ''Doom 3'', 2016) main installment in the ''Franchise/{{Doom}}'' franchise, developed by Creator/IdSoftware and published by Creator/{{Bethesda}} for the PC, UsefulNotes/PlayStation4, and UsefulNotes/XboxOne on May 13, 2016. It was ported to the UsefulNotes/NintendoSwitch on November 10, 2017.
You play as a [[HeroicMime silent]], unnamed SpaceMarine who wakes up in a creepy stone coffin surrounded by zombies. After fighting your way through them and acquiring a suit of PoweredArmor from an equally-creepy nearby sarcophagus, you discover you're inside a Union Aerospace Corporation facility on Mars in the middle of a [[HellOnEarth demonic invasion]]. What were you doing in a coffin? ''Irrelevant.'' Why are demons invading Mars? ''Doesn't matter.'' You're a [[ComicBook/{{DOOM}} berserker-packin' man and a half]] who's here to ShootEverythingThatMoves until TheLegionsOfHell are obliterated. [[MythologyGag Rip and tear]], until it is done.
Originally announced in 2008 as "Doom 4", the game is meant to be a GenreThrowback to the early days of {{First Person Shooter}}s; 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: GunAccessories that provide SecondaryFire modes, having grenades and PistolWhip assigned to their own buttons (a la ''Franchise/{{Halo}}''), melee-range "Glory Kill" {{Finishing Move}}s 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 Dump}}s hidden in the EncyclopediaExposita. The game also features competitive multiplayer, where up to twelve players duke it out in a variety of game modes, and a LevelEditor called [=SnapMap=], which allows one to create their own map with custom game logic.
----
!''DOOM'' provides examples of:
* HundredPercentCompletion: 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.
* AbsurdlyHighLevelCap: In multiplayer, there are 600 total levels the player can advance through, with 50 levels scattered across 12 epsilons.
* ActionBomb: Lost Souls fly straight towards you, kamikaze-style.
* ActionizedSequel: While ''Doom 3'' was more of a survival-horror, this entry is a straight-up action game in the vein of the first two.
* AdaptationalVillainy: In ''Doom 3'' the [=UAC=] were somewhat amoral, but were surprisingly sensible and generally averted the stupidity of most evil corporations like [[Franchise/ResidentEvil Umbrella]]. In this ''Doom'', the [=UAC=] operate like a cult and are essentially a combination of Satanism and [[Franchise/DeadSpace Unitology]], getting there by way of [[Franchise/{{Alien}} Weyland-Yutani]], but PlayedForLaughs (most of the time) while operating with a hilariously cavalier attitude towards the deaths of their employees. [[ArsonMurderAndJaywalking Oh, and they don't let their employees take the weekends off.]] [[LaughablyEvil Those monsters.]]
* AffablyEvil: WellIntentionedExtremist 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. [[spoiler:Even after turning on Doomguy, he admits Doomguy might be right to completely obliterate Hell, and merely [[ReleasedToElsewhere 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 [[spoiler:sacrifice and meltdown.]]
* AndYourRewardIsClothes: In multiplayer, playing through matches and advancing through levels and epsilons unlocks extra customization options (armors, colors, and patterns) for the player's personal marine (and their weapons). Completing objectives will unlock customization options earlier. [[spoiler:Reaching Epsilon XI Level 50 unlocks the Doom Slayer's armor from the campaign.]]
* AntiFrustrationFeatures: 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.
* AlternateFire: Each weapon except for the Chainsaw, Super Shotgun, and BFG-9000 can have one of two GunAccessories installed.
** The pistol, Heavy Assault Rifle, Shotgun, and Plasma Rifle can have ChargeAttack alts: the shotgun charges either Rapid-Fire or a grenade launcher. The HAR can charge up a salvo of six missiles. The plasma gun charges up a heat sink as it fires normally; this can be discharged right up an enemy's nose. The pistol is charged by holding down the alt-fire button, gradually gaining power.
** The Chaingun and plasma rifle can have "Seperate but Unrelated" alts: The chaingun can be split into 3 miniguns, tripling its firing rate at the cost of both slowing you down and overloading its coolant system, and the plasma gun can fire a shot with extra electricity, stunning enemies.
** The HAR can alternatively be equipped with a sniper scope.
** The chaingun can be equipped with a secondary rotor which allows it to be fired without first spooling up. This can overlap with the Charge Attack category, because its Master upgrade allows it to superheat its bullets.
* ApocalypticLog: 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 [[HorrifyingTheHorror how they're all terrified of him]].
* AreTheseWiresImportant: Doomguy's preferred method for dealing with Argent Energy equipment, despite Hayden's demands that he use utmost care.
* ArmCannon: Possessed Soldiers and Security have guns fused to their right arms. Hell Razers shoot beams out of their right arms.
* ArtifactOfDoom: The Crucible.
* ArtificialBrilliance: Go ahead, [[ShmuckBait 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...
* ArtificialStupidity: 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 [[TooDumbToLive stand in place chucking more fireballs while you barrel towards them with a shotgun.]]
* AscendedMeme:
** The opening cutscene quotes the phrase "Rip and Tear" from the ''ComicBook/{{Doom}}'' comic, though the context is different enough to make it chilling.
** There are a huge number of trophies quoting the ''ComicBook/{{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 [[CaptainObvious/VideoGames "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 Website/{{YTMND}} .gif edit of the Doomguy [[http://static.fjcdn.com/gifs/Monster+s+pov+from+doom_a11423_4968876.gif doing this cheerful little move.]]
* AscendedFanfic: The game borrows the Glory Kill mechanic and ''Ultra-Nightmare'' difficulty[[note]]where dying returns you to the start of the game[[/note]] of the ''VideoGame/BrutalDoom'' mod. Mods to upgrade and improve weapons are hidden around the levels, similar to ''VideoGame/DoomTheRoguelike''. 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 VideoGame/HideousDestructor.
** Gone full-circle for ''VideoGame/BrutalDoom'', since [[https://www.youtube.com/watch?v=863D-TWAbJQ SgtMark is adding the weapons and runes from the game into the mod.]]
** There is an implication that every Doom .wad and mod has existed in some way or form, as the Slayer's Testament states that countless dimensions are found and invaded by Hell.
* AttackAttackAttack: 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.
* BadBoss: [[BigBad 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. [[spoiler: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 [[TropeNamer one and only]] BFG-9000, a massive plasma cannon that fires hyper-charged hell energy [[spoiler:and gets used to [[FinishingMove Glory Kill]] the FinalBoss.]] And in the current lore, it's described as seeking out enemies with the charged nature of the plasma and boiling them alive, a possible reference to the fact that the original ''VideoGame/{{Doom}}'s'' BFG sent out a cone of hitscan rays from the player's position to damage enemies in their line of sight upon detonation of its projectile.
** 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 can tear apart demons ([[NecessaryDrawback and your ammo]]) within a matter of seconds.
* BigBad: Olivia Pierce, a scientist-turned-cultist who believes that having the world engulfed by Hell will lead to the next step in human evolution. [[spoiler: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.]]
* BigGood: Samuel Hayden, who extracted the Doomguy from Hell to be the ultimate safeguard against a demonic invasion. [[spoiler:Though he's still a WellIntentionedExtremist who wants to exploit Hell for its resources.]]
** It is also implied that God exists in this game, as it is stated in the [[spoiler: slayer testaments that Doomguy was endowed with supernatural fighting ability by an angel.]]
* BigRedDevil: Imps and Barons of Hell, hell-spawned demons with red skin and horns.
* TheBerserker: The Glory Kill and Berserk artifact mechanics encourage you to run through enemy attacks to rip demons limb from limb.
* BlackComedy: 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.
* BodyArmorAsHitPoints: Armor in this game acts like bonus health; any damage you take is taken out on armor first.
* BodyHorror: Argent energy does very ugly things to the the humans it affects. Basic Possessed have gaping holes where their eyes and noses should be, and Possessed Soldiers have their armor fused to their skin.
* BoomHeadshot: Aiming for the head will deal amplified damage-and cause the enemy's head to [[YourHeadASplode 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."
* BoringYetPractical:
** The Tactical Scope for the Heavy Assault Rifle and the Gatling Rotor for the Chaingun. Compared to the [[StuffBlowingUp Micro-Missile Launcher]] and the [[MoreDakka 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.
** The runes that affect Glory Kills can be considered this. With the exception of Armored Offensive, they don't really do anything spectacular other than make it easier to pull off Glory Kills whether it be increasing the stun time of enemies or increasing the range in which they can be executed, but damn if they don't make siphoning health (and armor with Armored Offensive) far easier this way!
* BorrowedBiometricBypass: 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. The latter includes a subversion of the usual trope, as there's a second biometric detector inside the chamber that this trick can't fool, and your mismatched readings trip the security system.
* BottomlessMagazines: 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. You can find ammo pickups for your equipment (the two grenade types and the hologram) too, but since they also automatically recharge over time, you can never actually run out of them.
* BrainUploading: 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.
* BroadStrokes: 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.
* BrutalBonusLevel: 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 [[CheckpointStarvation no checkpoints,]] so a single mistake can send you back to the very beginning.
* BulletTime: 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.
* CallBack: Trophies include [=E1M1=], IDKFA, Shareware and [[ArsonMurderAndJaywalking IPXSETUP.EXE]].[[note]]The latter is to do one multiplayer game, which normally used, on the original Doom, ipxsetup.exe to handle the netcode. Nowadays, the supplier provides it.[[/note]]
* TheCameo: The [[spoiler: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. [[spoiler:[[EasterEgg Unless you shoot a rocket into its forehead, which causes it to shoot out a collectible doll and play its speech from Doom II.]]]]
* CannedOrdersOverLoudspeaker: All over the place in the UAC facilities.
* CanonForeigner: 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.
* CantCatchUp: The pistol, predictably. Even with its new charging shot feature, by the time one can invest enough points in it to fully upgrade its potential, the player has already acquired a number of far better weapons. It may have an infinite ammo supply, but there's plenty of ammo scattered throughout the level. That isn't even going into the details of the "Rich Get Richer" rune.
* ChainsawGood: The chainsaw returns as a melee option, but its mechanics have changed. It's now a OneHitKill 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.
** Subtly done on audio level. Mick Gordon morphed his music with a sample of the chainsaw sound from the original games to create the main menu theme.
* ChargedAttack: Most of the weapon mods work like this in some way.
* TheComicallySerious: Samuel Hayden. His frequent exasperation and the seriousness he displays to Doomguy's more '[[TheBerserker simple-minded]]' decisions is a source for some hilarity in the game.
** When meeting in person and if the player decides to shoot, Samuel will simply say "Save your ammunition".
---> '''Samuel Hayden:''' [[DeadpanSnarker Your affinity for guns is apparent]]. I'm confident you'll find [[{{BFG}} something useful]] there as well.
* TheCorruption: [[spoiler: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 "[[WellIntentionedExtremist bettering mankind]]" [[MotiveDecay to]] "[[AGodAmI 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 [[BodyHorror showing signs of grievous injury/necrosis]] as well as a bad case of ProphetEyes.]]
* CrapsackWorld: 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''.
* DamnYouMuscleMemory: 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 [[ChainsawGood chainsaw]], which tangentially functions as a reload, and using it on a demon does indeed net you more ammo.
* DaylightHorror: Unlike in ''VideoGame/{{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.
* DeadlyDodging: 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.
* DealWithTheDevil: This amounts to how the events of the game got started. [[spoiler: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. [[spoiler:Olivia crosses over into TooDumbToLive territory by trying to get into Hell to make the demons give what they promised her. [[BeCarefulWhatYouWishFor 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.]]]]
* DegradedBoss: [[EliteMooks The Hell Knights]] compared to [[MiniBoss 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.
* DistaffCounterpart: Olivia Pierce is basically Dr. Betruger with no Y chromosome.
* DoubleJump: Doomguy eventually comes across some thruster boots that let him jump an additional time in the air.
* DualBoss: [[spoiler:Finished off the first Hell Guard? Don't celebrate just yet, as you immediately face ''two of them'' right after]].
* DraggedOffToHell: Happens quite a few times, [[spoiler:though the last few are a deliberate effort so you can break into Hell.]]
* TheDreaded: [[OneManArmy 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 [[SealedGoodInACan 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.
* DramaticGunCock: Doomguy pumps his shotgun right as he's about to get off the elevator once the first mission, following the title screen.
* DroppedABridgeOnHim: Or in the Doom Slayer's case, a temple. It doesn't take.
* EarlyBirdCameo: The Heavy Machine Gun appeared in the Steam version of ''[[VideoGame/QuakeIIIArena Quake Live]]''.
* ElectronicSpeechImpediment: [[spoiler:VEGA, as you're shutting it down in the second-to-last level]].
* EliteMooks: The [=UAC=]'s red-armored Elite Guard (whose armor can be earned in multiplayer) were elite troops cybernetically enhanced by their PoweredArmor suits. However, this made them dangerous enough that Hayden had a SelfDestructMechanism 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 AuthorityEqualsAsskicking, apparently.
* EmergencyWeapon: 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.
*** If you choose to specialize in the Pistol[[note]]Purchase all of its upgrades, and then complete the Mastery challenge of pulling off 15 headshot kills with it, something trivially easy on the first level where there are a lot of basic Possessed[[/note]], it goes from a sidearm you generally will only use if you run out of ammo to a hand cannon that can one-shot Possessed Soldiers (which take 2 shots from the Shotgun at close range to kill).
* EstablishingCharacterMoment: 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 [[spoiler: a backup of VEGA before overloading its core to open another portal.]]
* EvenEvilHasStandards: The demons may be evil but their writings indicate a loathing of betrayers, referring to them as "wretched".
* EverythingFades: Demon corpses and gibs disintegrate after a few seconds. As with ''Doom 3'', this was likely meant to ease up on memory.
* EvilBrit: Olivia Pierce has an English accent, and is the game's BigBad.
* EvilInc: 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.
* EvilIsVisceral: 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.
* EvilSoundsDeep: 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.
* EvilVersusEvil: While it's not terribly common due to SetAMookToKillAMook 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 [[FinishingMove Glory Kill]] state if they hit each other, they only care about pounding the Doom Slayer's face in during a fight.
* ExactWords: The DealWithTheDevil that frames the story's start.
** For Olivia Pierce, [[spoiler: she wanted power, and was ''painfully'' transfigured into the Spider Mastermind.]]
** It applies to the backstory, too. [[spoiler: The Betrayer of Argent D'Nur wanted his son revived, and he was... as the ''Icon of Sin''.]]
* ExcusePlot: 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.
* ExplodingBarrels: All over the place, and they're colored red too. [[spoiler:The acid barrel sprites appear in the classically-styled areas and maps]].
* ExplosiveDecompression: {{Downplayed|Trope}}. 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...
* ExplosiveLeash: 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 [[VideoGame/{{Doom 3}} 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".
* EyeScream: 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.
* FaceHeelTurn: [[spoiler: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 [[{{Unobtainium}} Argent Energy]] everyone's after.]]
* FateWorseThanDeath: [[spoiler:[[DemBones 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.]]
** [[spoiler: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.]]
* FeaturelessProtagonist: The Doom Guy has no name nor dialogue just as before. It's not even clear if he's human or just ''[[HumanAliens looks]]'' human. However, this doesn't detract from him having a personality of his own.
* FilkSong: [[http://youtu.be/kjIVkl34Vig Hell To Pay]], [[CrowningMusicOfAwesome head-bangingly]] provided by Music/MiracleOfSound
* FinalBoss: [[spoiler:Olivia Pierce, who transforms into [[BigCreepyCrawlies the Spider Mastermind]], is the final enemy you face in the game.]]
* FinalDeath: Playing on Ultra-Nightmare means that you only have one life. If you die, it's back to the beginning.
* FinishingMove: 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. [[spoiler: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.]]
* FullFrontalAssault: Doom Guy starts the game completely naked and StrappedToAnOperatingTable 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.
* GameBreakingBug: 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.
* GeniusBruiser: 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 [[spoiler: personally lead an expedition into Hell to retrieve the Doom Marine from his tomb.]]
* GenreThrowback: 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.
* GlassCannon: 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.
* GodzillaThreshold: 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 [[spoiler: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, [[GodzillaThreshold and may we never need you again]].
* GoneHorriblyRight: The researchers attempted to give the [[spoiler: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.
* GoodScarsEvilScars: 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.
* GreaterScopeVillain: 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 [[FinalBoss Spider Mastermind]].
* GrievousHarmWithABody: 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.
* GunNut: At one point, Samuel Hayden notes that Doomguy seems to have an affinity for guns.
* HalfTheManHeUsedToBe: This is often the result of using [[ChainsawGood 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.
* HarderThanHard: 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.
* HaveANiceDeath: 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.
* HeavilyArmoredMook: Mancubus and Pinky monsters now have armor covering their bodies, protecting them from any hits on those parts.
* HeelFaceTurn:
** [[spoiler:The Slayer's Testament mentions the Doomguy was helped by [[DefectorFromDecadence a denizen of hell who decided to aid him in his quest]], constructing the Praetor Armor he wears.]]
** [[spoiler:Depending on how you interpret Slayer's Testament I, the Doomguy himself is "The Betrayer" who doomed Argent D'nur in an attempt to bring back his dead son, only to [[PapaWolf swear eternal vengeance on Hell when they double crossed him.]]]]
* HellIsThatNoise: 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.
* HellOnEarth: Demons are invading from Hell into our universe through a rip in reality on Mars.
* HeWhoFightsMonsters: 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.
* HiddenDepths: 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. [[spoiler: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.
* HiddenVillain: 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.
* HorrifyingTheHorror: Later in the game, it's revealed that the demons are [[spoiler: ''absolutely terrified'' of Doomguy]], seeing him as an unstoppable fighting machine who they struggled to seal away.
* HumanSacrifice: As they fall to Hell's corruption, the UAC start performing human sacrifices in their research in Argent Energy. [[FalseReassurance Don't worry]], it was entirely voluntary on the sacrifices' part.
* HyperspaceArsenal: In deliberate defiance of [[LimitedLoadout 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).
* ICannotSelfTerminate: VEGA says this [[spoiler:when you're going towards his core to shut him down. Therefore, he helps you with the process]].
* IdiosyncraticDifficultyLevels: 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.
** "[[EasyModeMockery I'm Too Young To Die]]" (Easy mode)
** "Hurt Me Plenty" (Normal mode)
** "[[Literature/AClockworkOrange Ultra-Violence]]" (Hard mode)
** "[[HarderThanHard Nightmare]]" (Very Hard mode)
** "[[UpToEleven Ultra-Nightmare]]" (Very Hard mode, but you have to start the game all over again when you die)
* InterfaceScrew: 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.
* IWasQuiteTheLooker: 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 [[WesternAnimation/TheSimpsons 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.
* JumpPhysics: 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.
* LargeAndInCharge: Zigzagged with Samuel Hayden, his robotic body eclipses the Doomguy in size and stands higher than a Hell Knight, [[NonActionGuy but he isn't interested in picking a fight directly]]. [[spoiler: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.
* KillEnemiesToOpen: The demonic presence has a lot of areas placed under lockdown, so they need to be cleared of demons in order to advance.
* LaserBlade: [[spoiler: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 CoolSword.]]
* LastChanceHitPoint: 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 BulletTime to escape your predicament.
* LeaningOnTheFourthWall: You're either playing as the SoleSurvivor of an ancient land invaded by Hell who swore eternal vengeance on the demons, or the PlayerCharacter of ''VideoGame/{{Doom}}'' and ''VideoGame/{{Doom II}}'' who became such a MemeticBadass over those games he's now some sort of [[EternalHero everlasting vengeance god]].
* LeParkour: The Doomguy is surprisingly agile, able to grip onto ledges to find secrets and hidden powerups.
* LevelEditor: The game lets you create [=SnapMaps=] that can be shared online.
* LifeDrain: The Siphon Grenade steals health from enemies in the blast radius and gives it back to the Doomguy.
* LighterAndSofter: 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''.
* LoweredMonsterDifficulty: Even with your downgraded weapon loadout, the Cyberdemon battle is a hell of a lot easier in the Tower of Babel classic map thanks to his strategy going back to [[AttackAttackAttack what it was in the original game]], with the rocket launcher being his only ranged attack.
* LudicrousGibs: A lot of the enemies can be easily gibbed. Enjoy a ''HELL'' of a bloodbath!
* MacGuffin: The Crucible.
* MacrossMissileMassacre:
** The Micro Missile mod for the Heavy Assault Rifle lets you fire six micro-sized missiles at a time. At full mastery it can fire as many darts as you have ammo without reloading.
*** 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.
* MadScientist: 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.
* MagikarpPower: The basic Pistol. While it's nowhere near as impressive compared to the other guns (and is practically obsolete once the player gets the shotgun), purchasing the pistol's upgrades make it a decent handgun. Then, if you take the time to complete the Mastery challenge for it (get 15 headshot kills, best done on the lowly Possessed), it one-shots Possessed Soldiers (something that takes 2 close-range shots from the shotgun to do) with no movement penalty. [[SubvertedTrope It's still no match for a basic shotgun though, and it takes a while to invest enough points to fully upgrade it. By the time that happens, the pistol still remains irrelevant]].
* MascotMook: 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.
* MinimalistCast: Besides the SilentProtagonist 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.
* MonsterShapedMountain: The Titan region in Hell is named after the giant, skeletal remains from Hell's greatest champion littering the landscape, [[spoiler:[[GreatOffscreenWar having been done in by the Doomguy at some point before the game.]]]]
* MookHorrorShow: 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.
* MythologyGag: ''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 [[https://i.redditmedia.com/zxycie_JTcnUT3JeWwnRE5-o14v_I3ytV7UkGOntXpk.jpg?w=644&s=5b0d7f45d3e3b09b3d8609f125ea1a7d illustration]] on Samuel's desk of [[spoiler: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 DoomDoors 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 [[Film/{{Doom}} Doom film]].
** The ''Doom II'' manual states that the Spider Mastermind isn't equipped with a plasma gun, and thank god for that. [[spoiler: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 [[spoiler: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, [[https://www.youtube.com/watch?v=ZmVOn4Qf_7k BFG Division]] contains a segment of the main riff from the original game's [[https://youtu.be/ETV9fPmieOM 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 [[https://www.youtube.com/watch?v=2U9pPMXqlA8 first see Olivia Pierce in person]] is a remix of [[https://www.youtube.com/watch?v=FMex4f8cwEY&index=5&list=PLAD2502F2CB75CC90 Suspense]] ([=E1M5=]) from the first game. The track that plays over the main menu, [[https://www.youtube.com/watch?v=nJI8JDnLH3Y 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 [[http://doomwiki.org/wiki/WAD .WAD file format]].
** There's an option to switch your weapon's onscreen position from the now-standard right corner to the center, mimicking the look of the classic games.
** The last note of the track that plays when you fight the Spider Mastermind is the first note of Spider Mastermind's theme from Doom 1 played backwards.
* NamesToRunAwayFromReallyFast: The forces of Hell, who collectively call themselves "The Slaves of Doom" are so terrified of the Doomguy they all know him as "[[RoaringRampageOfRevenge the Doom Slayer]]."
* NeckSnap: Doomguy does this on several Glory Kills. The game doesn't shy away from providing some [[SickeningCrunch appropiate sound effects]].
* NintendoHard: This game returns to the furious run n' gun gameplay style of the classic ''VideoGame/{{DOOM}}'' series, lacking conventions present in many other shooters released in its era such RegeneratingHealth and [[TakeCover 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 not a cakewalk, and defensive strategies like camping or turtling will only get you killed about 98% of time.
* NGOSuperpower: 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.
* NoFairCheating: 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.
* NoOSHACompliance: Counting how many absurdly flagrant safety violations the UAC is guilty of in their day-to-day operations is a fun little side game-- and an incredibly dangerous DrinkingGame, too. Of course, there's nothing in the game to suggest that the UAC operates with oversight of ''any'' kind, let alone regarding workplace safety.
* NoSell: 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.
* NostalgiaLevel: 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 [[spoiler:Icon of Sin]] makes a reappearance, still dead as a doornail.
** One of the levels in Hell features an adaptation of ''Dead Simple''.
* ObviouslyEvil: 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.
* OhCrap: The first time you are sent to Hell an ominous voice simply says "he is here" you can find runes about why the voice is not happy about it and there is a recorded conversation with Olivia where the voice is clearly angry she woke up the Doom Slayer.
* OneHitKO: The chainsaw now takes down anything in one hit, but it takes fuel to do it. Naturally, it doesn't work against bosses.
* OneHitPointWonder: One [[TimedMission Rune Challenge]] pits you against various demons from [[TheGoomba zombie and imp]] to [[LightningBruiser 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 [[BodyArmorAsHitPoints armor]] to survive.
* OneWordTitle
* PetTheDog: With how [[TheBerserker violent]] the Doomguy can be and [[ItAmusedMe how frequently he destroys expensive equipment for]] the [[{{Pun}} hell]] [[ItAmusedMe of it]], it's surprising that [[spoiler: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.
* PostPeakOil: 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.
* PoweredArmor: Doomguy's Praetor Suit, which according to the Slayer Testaments, [[spoiler:was created/improved by a demon who betrayed Hell and sided with him]].
* QuadDamage: Makes its ''Doom'' debut after being a staple item in id's ''VideoGame/{{Quake}}'', and shows up in both single-player and multiplayer.
* RatedMForManly: Oh HELL YES! Between the blood, the gore, the Glory Kills and the one-man onslaught against TheLegionsOfHell, 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 TheLegionsOfHell with all the guns and chainsaws you can carry, and how terrifying it would be ''[[HorrifyingTheHorror 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.
* RevisitingTheRoots: 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.
* RewardedAsATraitorDeserves: [[spoiler: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 [[CameBackWrong a demon]] because "the wages of treachery are suffering".
* RoaringRampageOfRevenge: What the Doomguy's motivation for fighting against Hell is hinted to be. Codex entries and The Slayer's Testament imply [[spoiler: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]].
* RocketJump: You can get a boost for your jumps by using the Gauss Cannon's recoil to get a little more airtime.
* RocketTagGameplay: 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.
* SaveScumming: 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.
* {{Satire}}: Yes, seriously. The fact that, in the future, humanity chose to take energy from ''hell itself'' rather than any other renewable energy source should make this obvious. In addition, the Argent Facility having several clear human rights violations and questionably ethical experimentation on demons brings to mind shady corporations that treat their employees like crap. In the end, the UAC is every real-life MegaCorp taken UpToEleven.
* SceneryGorn: 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. [[UpToEleven Usually all three.]]
* SceneryPorn: 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 [[JustForPun one hell of an impression.]]
* SealedGoodInACan: The Doomguy. [[spoiler: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.]]
* SecondaryFire: Some weapon mods give secondary firing modes, like an explosive shot for the shotgun or mini-missiles for the heavy assault rifle.
* SecretLevel: 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.
* SelfImposedChallenge: [[https://www.youtube.com/watch?v=_S9G8tvfCNI This guy]] beats [[FinalDeathMode Ultra-Nightmare]] using ''only the pistol''.
* SequelHook:
** After you defeat [[spoiler: Olivia Pierce]], you are tethered back to Mars by [[spoiler:Hayden]], [[WellIntentionedExtremist who still believes that he's in the right]] before snagging [[{{MacGuffin}} the Crucible]] from the Doomguy and, [[YouHaveOutlivedYourUsefulness rather than kill him]], decides to send him elsewhere to prevent him from interfering with his plans, [[{{Cliffhanger}} but remarking that they'll meet again soon enough...]] In this instance [[spoiler: Samuel]] has no choice, killing the Doom Slayer ensures that, should something as catastrophic as this ever happens again, no one who can stand up to the demon invasion will be left. Also? It might not be possible.
*** The game also tantalizes you by [[spoiler: showing Hayden rip the Crucible off your person ''and ignite it like a lightsaber into a giant hellish energy blade'' before walking off into the darkness and rolling the credits.]]
** The Doomguy [[spoiler:saves a backup of VEGA before destroying him]].
* SetAMookToKillAMook: 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.
* ShieldBearingMook: Possessed Security have large shields that defend them from frontal attacks.
* ShoutOut:
** As with the original, one of the difficulty settings is "[[Literature/AClockworkOrange Ultra-Violence]]".
** If you die by falling into a lava pit, the Doom Marine will [[Film/Terminator2JudgmentDay give a Terminator-esque thumbs up]].
** The illustration that you can find on Samuel Hayden's desk of [[spoiler:the Doomguy fighting demons]] is in the style of the Ark of the Covenant's woodcut illustration in ''Film/RaidersOfTheLostArk''.
** The Pistol and BFG-9000 act very similarly to ''VideoGame/QuakeII'''s Blaster and BFG 10K, respectively. The Pistol's visual design also resembles the Dominator pistol from ''Anime/PsychoPass''.
** Just as in VideoGame/QuakeIIIArena, picking up extra armor that surpasses your default meter will decay over time.
** One of the multiplayer taunts is [[Series/TheFreshPrinceOfBelAir Carlton's dance.]]
** In one of the Hell levels, it's possible to find a skeleton with a [[VideoGame/TheElderScrollsVSkyrim horned helmet and an arrow through its knee]].
** One of the Hell levels also has the helmet of VideoGame/CommanderKeen, 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 [[VideoGame/{{Fallout}} Vault-Tec]] logo on it.
** An early collectible is "Vaultguy", Doomguy with his armor painted like a Vault suit. A couple of the late-game collectable figurines are [[VideoGame/CommanderKeen Keenguy]] and [[{{VideoGame/Quake}} Quakeguy]]. [[VideoGame/QuakeIIIArena Phobos]] is there as well.
** The demons ApocalypticLog is titled the Music/{{Slayer}} Music/{{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''.
** The hidden ''Super Turkey Puncher 3'' arcade cabinet has a logo that's designed to resemble that of ''VideoGame/StreetFighterAlpha 3''.
** One of the Cyberdemonic armors from the multiplayer mode has [[Anime/MobileSuitGundam a spiked pauldron on its left shoulder and a small shield on its right]].
* ShowsDamage: Some enemies can have limbs blown off without actually being killed. [[spoiler:Olivia Pierce as the [[OneWingedAngel 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.]]
* ShutUpHannibal: Any justifications Hayden comes up with are ignored by the Doomguy. Doomguy even takes the time to listen to his excuses for why mining Hell is a good idea before smashing the equipment to show that he does hear Hayden, he disagrees.
* SuspiciousVideoGameGenerosity: 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.
* StaticRoleExchangeableCharacter: As with StealthSequel, it's made ambiguous as to ''what'' this game's Doomguy is. [[spoiler: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.]]
* StealthSequel: It's implied that the Doomguy in this game [[spoiler:is actually the very same one from the original two ''Doom'' games]].
* StylisticSuck: 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).
* TranquilFury: How else can you describe a man who carves through the forces of hell without uttering a word.
* TurnedAgainstTheirMasters: The Revenants, Mancubi, and Cyberdemon were all created by the [=UAC=] to be used as weapons. Being TooDumbToLive, they seem to have engaged in mass production before even having figured out a way to control the damn things.
* TheReasonYouSuckSpeech: [[spoiler: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.]]
* TheUnfought: [[spoiler:Samuel Hayden]].
-->[[spoiler:'''Samuel Hayden:''']] I am not the villain in this story. I do what I do because there is no choice.
* TeethClenchedTeamwork: 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.
* TitleDrop: The demons call Hell "Doom", with their collective forces the "Slaves of Doom", and the Doomguy himself known as "the Doom Slayer". [[DoomyDoomsOfDoom Really, the word "doom" is all over the place in this game.]]
* TookALevelInBadass: 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 Soldier is a good deal tougher and hardier than the classic Zombieman, and now packs a plasma weapon instead of a puny rifle.
** 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 [[LightningBruiser 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 GlassCannon that gradually became passé as time went on, got a pretty significant buff that turns them into {{Lightning Bruiser}}s with the bonus of [[DeathFromAbove being able to fly and smoke you out with]] [[MacrossMissileMassacre 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, [[{{Expy}} 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 DamageSponge 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.
** [[spoiler: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.]]
* TranquilFury: Doomguy never speaks, but still turns the forces of hell to LudicrousGibs. Also seen with Samuel Hayden, where he [[ShutUpHannibal regularly destroys Hayden's means of communication]] but never directly attacks the head of the UAC.
* TurnsRed: Inverted [[spoiler:with the Spider Mastermind, which becomes increasingly bruised and crippled after a considerable number of hits are landed on it.]]
* {{Unobtainium}}: The [[AppliedPhlebotinum Argent energy]] used to power everything drives a portion of the story, [[spoiler:being from Hell itself and all.]]
* UnstoppableRage: 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 [[TranquilFury demeanour]] [[NoHoldsBarredBeatDown towards]] [[TheresNoKillLikeOverKill any demon]] in the present day showcases very clearly.
* UpToEleven: 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.
* UtopiaJustifiesTheMeans: 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''.
* VideoGameCrueltyPotential: Taking numerous pages from ''VideoGame/BrutalDoom'', 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.
* WaveMotionGun: 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.
* WeCanRebuildHim: 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.
* WellIntentionedExtremist:
** Both [[TheQuisling Olivia Pierce]] and [[{{Cyborg}} Samuel Hayden]], the former working with Hell to bring about a new world for mankind and the latter [[spoiler:wanting to utilize Hell for [[{{Unobtainium}} its resources]] to usher in a better world for mankind as well. Although in Olivia's case it [[TheCorruption eventually degenerates]] into "Obtain God-like power".]]
** Doomguy fits this, considering that his world was destroyed by TheLegionsOfHell, it seems justifiable in wiping out every last trace of it when he reawakens to try and stop Earth from suffering the same fate.
* WhatTheHellHero: 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.
* WhenAllYouHaveIsAHammer: 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.
* WorldOfBadass: The main character is an immortal butcher machine. The CorruptCorporateExecutive 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 [[spoiler: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 PowerArmor''. Everyone else has GUNS grafted to their arms and/or mouths.
* WorthyOpponent: 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.!

[[caption-width-right:350:[[{{Tagline}} Fight Like Hell.]]]]
->''"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 ''Franchise/{{Doom}}'' franchise, developed by Creator/IdSoftware and published by Creator/{{Bethesda}} for the PC, UsefulNotes/PlayStation4, and UsefulNotes/XboxOne on May 13, 2016. It was ported to the UsefulNotes/NintendoSwitch on November 10, 2017.
You play as a [[HeroicMime silent]], unnamed SpaceMarine who wakes up in a creepy stone coffin surrounded by zombies. After fighting your way through them and acquiring a suit of PoweredArmor from an equally-creepy nearby sarcophagus, you discover you're inside a Union Aerospace Corporation facility on Mars in the middle of a [[HellOnEarth demonic invasion]]. What were you doing in a coffin? ''Irrelevant.'' Why are demons invading Mars? ''Doesn't matter.'' You're a [[ComicBook/{{DOOM}} berserker-packin' man and a half]] who's here to ShootEverythingThatMoves until TheLegionsOfHell are obliterated. [[MythologyGag Rip and tear]], until it is done.
Originally announced in 2008 as "Doom 4", the game is meant to be a GenreThrowback to the early days of {{First Person Shooter}}s; 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: GunAccessories that provide SecondaryFire modes, having grenades and PistolWhip assigned to their own buttons (a la ''Franchise/{{Halo}}''), melee-range "Glory Kill" {{Finishing Move}}s 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 Dump}}s hidden in the EncyclopediaExposita. The game also features competitive multiplayer, where up to twelve players duke it out in a variety of game modes, and a LevelEditor called [=SnapMap=], which allows one to create their own map with custom game logic.
----
!''DOOM'' provides examples of:
* HundredPercentCompletion: 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.
* AbsurdlyHighLevelCap: In multiplayer, there are 600 total levels the player can advance through, with 50 levels scattered across 12 epsilons.
* ActionBomb: Lost Souls fly straight towards you, kamikaze-style.
* ActionizedSequel: While ''Doom 3'' was more of a survival-horror, this entry is a straight-up action game in the vein of the first two.
* AdaptationalVillainy: In ''Doom 3'' the [=UAC=] were somewhat amoral, but were surprisingly sensible and generally averted the stupidity of most evil corporations like [[Franchise/ResidentEvil Umbrella]]. In this ''Doom'', the [=UAC=] operate like a cult and are essentially a combination of Satanism and [[Franchise/DeadSpace Unitology]], getting there by way of [[Franchise/{{Alien}} Weyland-Yutani]], but PlayedForLaughs (most of the time) while operating with a hilariously cavalier attitude towards the deaths of their employees. [[ArsonMurderAndJaywalking Oh, and they don't let their employees take the weekends off.]] [[LaughablyEvil Those monsters.]]
* AffablyEvil: WellIntentionedExtremist 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. [[spoiler:Even after turning on Doomguy, he admits Doomguy might be right to completely obliterate Hell, and merely [[ReleasedToElsewhere 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 [[spoiler:sacrifice and meltdown.]]
* AndYourRewardIsClothes: In multiplayer, playing through matches and advancing through levels and epsilons unlocks extra customization options (armors, colors, and patterns) for the player's personal marine (and their weapons). Completing objectives will unlock customization options earlier. [[spoiler:Reaching Epsilon XI Level 50 unlocks the Doom Slayer's armor from the campaign.]]
* AntiFrustrationFeatures: 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.
* AlternateFire: Each weapon except for the Chainsaw, Super Shotgun, and BFG-9000 can have one of two GunAccessories installed.
** The pistol, Heavy Assault Rifle, Shotgun, and Plasma Rifle can have ChargeAttack alts: the shotgun charges either Rapid-Fire or a grenade launcher. The HAR can charge up a salvo of six missiles. The plasma gun charges up a heat sink as it fires normally; this can be discharged right up an enemy's nose. The pistol is charged by holding down the alt-fire button, gradually gaining power.
** The Chaingun and plasma rifle can have "Seperate but Unrelated" alts: The chaingun can be split into 3 miniguns, tripling its firing rate at the cost of both slowing you down and overloading its coolant system, and the plasma gun can fire a shot with extra electricity, stunning enemies.
** The HAR can alternatively be equipped with a sniper scope.
** The chaingun can be equipped with a secondary rotor which allows it to be fired without first spooling up. This can overlap with the Charge Attack category, because its Master upgrade allows it to superheat its bullets.
* ApocalypticLog: 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 [[HorrifyingTheHorror how they're all terrified of him]].
* AreTheseWiresImportant: Doomguy's preferred method for dealing with Argent Energy equipment, despite Hayden's demands that he use utmost care.
* ArmCannon: Possessed Soldiers and Security have guns fused to their right arms. Hell Razers shoot beams out of their right arms.
* ArtifactOfDoom: The Crucible.
* ArtificialBrilliance: Go ahead, [[ShmuckBait 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...
* ArtificialStupidity: 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 [[TooDumbToLive stand in place chucking more fireballs while you barrel towards them with a shotgun.]]
* AscendedMeme:
** The opening cutscene quotes the phrase "Rip and Tear" from the ''ComicBook/{{Doom}}'' comic, though the context is different enough to make it chilling.
** There are a huge number of trophies quoting the ''ComicBook/{{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 [[CaptainObvious/VideoGames "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 Website/{{YTMND}} .gif edit of the Doomguy [[http://static.fjcdn.com/gifs/Monster+s+pov+from+doom_a11423_4968876.gif doing this cheerful little move.]]
* AscendedFanfic: The game borrows the Glory Kill mechanic and ''Ultra-Nightmare'' difficulty[[note]]where dying returns you to the start of the game[[/note]] of the ''VideoGame/BrutalDoom'' mod. Mods to upgrade and improve weapons are hidden around the levels, similar to ''VideoGame/DoomTheRoguelike''. 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 VideoGame/HideousDestructor.
** Gone full-circle for ''VideoGame/BrutalDoom'', since [[https://www.youtube.com/watch?v=863D-TWAbJQ SgtMark is adding the weapons and runes from the game into the mod.]]
** There is an implication that every Doom .wad and mod has existed in some way or form, as the Slayer's Testament states that countless dimensions are found and invaded by Hell.
* AttackAttackAttack: 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.
* BadBoss: [[BigBad 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. [[spoiler: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 [[TropeNamer one and only]] BFG-9000, a massive plasma cannon that fires hyper-charged hell energy [[spoiler:and gets used to [[FinishingMove Glory Kill]] the FinalBoss.]] And in the current lore, it's described as seeking out enemies with the charged nature of the plasma and boiling them alive, a possible reference to the fact that the original ''VideoGame/{{Doom}}'s'' BFG sent out a cone of hitscan rays from the player's position to damage enemies in their line of sight upon detonation of its projectile.
** 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 can tear apart demons ([[NecessaryDrawback and your ammo]]) within a matter of seconds.
* BigBad: Olivia Pierce, a scientist-turned-cultist who believes that having the world engulfed by Hell will lead to the next step in human evolution. [[spoiler: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.]]
* BigGood: Samuel Hayden, who extracted the Doomguy from Hell to be the ultimate safeguard against a demonic invasion. [[spoiler:Though he's still a WellIntentionedExtremist who wants to exploit Hell for its resources.]]
** It is also implied that God exists in this game, as it is stated in the [[spoiler: slayer testaments that Doomguy was endowed with supernatural fighting ability by an angel.]]
* BigRedDevil: Imps and Barons of Hell, hell-spawned demons with red skin and horns.
* TheBerserker: The Glory Kill and Berserk artifact mechanics encourage you to run through enemy attacks to rip demons limb from limb.
* BlackComedy: 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.
* BodyArmorAsHitPoints: Armor in this game acts like bonus health; any damage you take is taken out on armor first.
* BodyHorror: Argent energy does very ugly things to the the humans it affects. Basic Possessed have gaping holes where their eyes and noses should be, and Possessed Soldiers have their armor fused to their skin.
* BoomHeadshot: Aiming for the head will deal amplified damage-and cause the enemy's head to [[YourHeadASplode 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."
* BoringYetPractical:
** The Tactical Scope for the Heavy Assault Rifle and the Gatling Rotor for the Chaingun. Compared to the [[StuffBlowingUp Micro-Missile Launcher]] and the [[MoreDakka 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.
** The runes that affect Glory Kills can be considered this. With the exception of Armored Offensive, they don't really do anything spectacular other than make it easier to pull off Glory Kills whether it be increasing the stun time of enemies or increasing the range in which they can be executed, but damn if they don't make siphoning health (and armor with Armored Offensive) far easier this way!
* BorrowedBiometricBypass: 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. The latter includes a subversion of the usual trope, as there's a second biometric detector inside the chamber that this trick can't fool, and your mismatched readings trip the security system.
* BottomlessMagazines: 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. You can find ammo pickups for your equipment (the two grenade types and the hologram) too, but since they also automatically recharge over time, you can never actually run out of them.
* BrainUploading: 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.
* BroadStrokes: 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.
* BrutalBonusLevel: 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 [[CheckpointStarvation no checkpoints,]] so a single mistake can send you back to the very beginning.
* BulletTime: 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.
* CallBack: Trophies include [=E1M1=], IDKFA, Shareware and [[ArsonMurderAndJaywalking IPXSETUP.EXE]].[[note]]The latter is to do one multiplayer game, which normally used, on the original Doom, ipxsetup.exe to handle the netcode. Nowadays, the supplier provides it.[[/note]]
* TheCameo: The [[spoiler: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. [[spoiler:[[EasterEgg Unless you shoot a rocket into its forehead, which causes it to shoot out a collectible doll and play its speech from Doom II.]]]]
* CannedOrdersOverLoudspeaker: All over the place in the UAC facilities.
* CanonForeigner: 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.
* CantCatchUp: The pistol, predictably. Even with its new charging shot feature, by the time one can invest enough points in it to fully upgrade its potential, the player has already acquired a number of far better weapons. It may have an infinite ammo supply, but there's plenty of ammo scattered throughout the level. That isn't even going into the details of the "Rich Get Richer" rune.
* ChainsawGood: The chainsaw returns as a melee option, but its mechanics have changed. It's now a OneHitKill 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.
** Subtly done on audio level. Mick Gordon morphed his music with a sample of the chainsaw sound from the original games to create the main menu theme.
* ChargedAttack: Most of the weapon mods work like this in some way.
* TheComicallySerious: Samuel Hayden. His frequent exasperation and the seriousness he displays to Doomguy's more '[[TheBerserker simple-minded]]' decisions is a source for some hilarity in the game.
** When meeting in person and if the player decides to shoot, Samuel will simply say "Save your ammunition".
---> '''Samuel Hayden:''' [[DeadpanSnarker Your affinity for guns is apparent]]. I'm confident you'll find [[{{BFG}} something useful]] there as well.
* TheCorruption: [[spoiler: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 "[[WellIntentionedExtremist bettering mankind]]" [[MotiveDecay to]] "[[AGodAmI 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 [[BodyHorror showing signs of grievous injury/necrosis]] as well as a bad case of ProphetEyes.]]
* CrapsackWorld: 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''.
* DamnYouMuscleMemory: 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 [[ChainsawGood chainsaw]], which tangentially functions as a reload, and using it on a demon does indeed net you more ammo.
* DaylightHorror: Unlike in ''VideoGame/{{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.
* DeadlyDodging: 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.
* DealWithTheDevil: This amounts to how the events of the game got started. [[spoiler: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. [[spoiler:Olivia crosses over into TooDumbToLive territory by trying to get into Hell to make the demons give what they promised her. [[BeCarefulWhatYouWishFor 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.]]]]
* DegradedBoss: [[EliteMooks The Hell Knights]] compared to [[MiniBoss 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.
* DistaffCounterpart: Olivia Pierce is basically Dr. Betruger with no Y chromosome.
* DoubleJump: Doomguy eventually comes across some thruster boots that let him jump an additional time in the air.
* DualBoss: [[spoiler:Finished off the first Hell Guard? Don't celebrate just yet, as you immediately face ''two of them'' right after]].
* DraggedOffToHell: Happens quite a few times, [[spoiler:though the last few are a deliberate effort so you can break into Hell.]]
* TheDreaded: [[OneManArmy 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 [[SealedGoodInACan 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.
* DramaticGunCock: Doomguy pumps his shotgun right as he's about to get off the elevator once the first mission, following the title screen.
* DroppedABridgeOnHim: Or in the Doom Slayer's case, a temple. It doesn't take.
* EarlyBirdCameo: The Heavy Machine Gun appeared in the Steam version of ''[[VideoGame/QuakeIIIArena Quake Live]]''.
* ElectronicSpeechImpediment: [[spoiler:VEGA, as you're shutting it down in the second-to-last level]].
* EliteMooks: The [=UAC=]'s red-armored Elite Guard (whose armor can be earned in multiplayer) were elite troops cybernetically enhanced by their PoweredArmor suits. However, this made them dangerous enough that Hayden had a SelfDestructMechanism 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 AuthorityEqualsAsskicking, apparently.
* EmergencyWeapon: 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.
*** If you choose to specialize in the Pistol[[note]]Purchase all of its upgrades, and then complete the Mastery challenge of pulling off 15 headshot kills with it, something trivially easy on the first level where there are a lot of basic Possessed[[/note]], it goes from a sidearm you generally will only use if you run out of ammo to a hand cannon that can one-shot Possessed Soldiers (which take 2 shots from the Shotgun at close range to kill).
* EstablishingCharacterMoment: 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 [[spoiler: a backup of VEGA before overloading its core to open another portal.]]
* EvenEvilHasStandards: The demons may be evil but their writings indicate a loathing of betrayers, referring to them as "wretched".
* EverythingFades: Demon corpses and gibs disintegrate after a few seconds. As with ''Doom 3'', this was likely meant to ease up on memory.
* EvilBrit: Olivia Pierce has an English accent, and is the game's BigBad.
* EvilInc: 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.
* EvilIsVisceral: 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.
* EvilSoundsDeep: 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.
* EvilVersusEvil: While it's not terribly common due to SetAMookToKillAMook 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 [[FinishingMove Glory Kill]] state if they hit each other, they only care about pounding the Doom Slayer's face in during a fight.
* ExactWords: The DealWithTheDevil that frames the story's start.
** For Olivia Pierce, [[spoiler: she wanted power, and was ''painfully'' transfigured into the Spider Mastermind.]]
** It applies to the backstory, too. [[spoiler: The Betrayer of Argent D'Nur wanted his son revived, and he was... as the ''Icon of Sin''.]]
* ExcusePlot: 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.
* ExplodingBarrels: All over the place, and they're colored red too. [[spoiler:The acid barrel sprites appear in the classically-styled areas and maps]].
* ExplosiveDecompression: {{Downplayed|Trope}}. 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...
* ExplosiveLeash: 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 [[VideoGame/{{Doom 3}} 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".
* EyeScream: 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.
* FaceHeelTurn: [[spoiler: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 [[{{Unobtainium}} Argent Energy]] everyone's after.]]
* FateWorseThanDeath: [[spoiler:[[DemBones 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.]]
** [[spoiler: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.]]
* FeaturelessProtagonist: The Doom Guy has no name nor dialogue just as before. It's not even clear if he's human or just ''[[HumanAliens looks]]'' human. However, this doesn't detract from him having a personality of his own.
* FilkSong: [[http://youtu.be/kjIVkl34Vig Hell To Pay]], [[CrowningMusicOfAwesome head-bangingly]] provided by Music/MiracleOfSound
* FinalBoss: [[spoiler:Olivia Pierce, who transforms into [[BigCreepyCrawlies the Spider Mastermind]], is the final enemy you face in the game.]]
* FinalDeath: Playing on Ultra-Nightmare means that you only have one life. If you die, it's back to the beginning.
* FinishingMove: 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. [[spoiler: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.]]
* FullFrontalAssault: Doom Guy starts the game completely naked and StrappedToAnOperatingTable 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.
* GameBreakingBug: 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.
* GeniusBruiser: 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 [[spoiler: personally lead an expedition into Hell to retrieve the Doom Marine from his tomb.]]
* GenreThrowback: 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.
* GlassCannon: 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.
* GodzillaThreshold: 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 [[spoiler: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, [[GodzillaThreshold and may we never need you again]].
* GoneHorriblyRight: The researchers attempted to give the [[spoiler: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.
* GoodScarsEvilScars: 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.
* GreaterScopeVillain: 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 [[FinalBoss Spider Mastermind]].
* GrievousHarmWithABody: 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.
* GunNut: At one point, Samuel Hayden notes that Doomguy seems to have an affinity for guns.
* HalfTheManHeUsedToBe: This is often the result of using [[ChainsawGood 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.
* HarderThanHard: 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.
* HaveANiceDeath: 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.
* HeavilyArmoredMook: Mancubus and Pinky monsters now have armor covering their bodies, protecting them from any hits on those parts.
* HeelFaceTurn:
** [[spoiler:The Slayer's Testament mentions the Doomguy was helped by [[DefectorFromDecadence a denizen of hell who decided to aid him in his quest]], constructing the Praetor Armor he wears.]]
** [[spoiler:Depending on how you interpret Slayer's Testament I, the Doomguy himself is "The Betrayer" who doomed Argent D'nur in an attempt to bring back his dead son, only to [[PapaWolf swear eternal vengeance on Hell when they double crossed him.]]]]
* HellIsThatNoise: 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.
* HellOnEarth: Demons are invading from Hell into our universe through a rip in reality on Mars.
* HeWhoFightsMonsters: 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.
* HiddenDepths: 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. [[spoiler: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.
* HiddenVillain: 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.
* HorrifyingTheHorror: Later in the game, it's revealed that the demons are [[spoiler: ''absolutely terrified'' of Doomguy]], seeing him as an unstoppable fighting machine who they struggled to seal away.
* HumanSacrifice: As they fall to Hell's corruption, the UAC start performing human sacrifices in their research in Argent Energy. [[FalseReassurance Don't worry]], it was entirely voluntary on the sacrifices' part.
* HyperspaceArsenal: In deliberate defiance of [[LimitedLoadout 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).
* ICannotSelfTerminate: VEGA says this [[spoiler:when you're going towards his core to shut him down. Therefore, he helps you with the process]].
* IdiosyncraticDifficultyLevels: 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.
** "[[EasyModeMockery I'm Too Young To Die]]" (Easy mode)
** "Hurt Me Plenty" (Normal mode)
** "[[Literature/AClockworkOrange Ultra-Violence]]" (Hard mode)
** "[[HarderThanHard Nightmare]]" (Very Hard mode)
** "[[UpToEleven Ultra-Nightmare]]" (Very Hard mode, but you have to start the game all over again when you die)
* InterfaceScrew: 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.
* IWasQuiteTheLooker: 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 [[WesternAnimation/TheSimpsons 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.
* JumpPhysics: 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.
* LargeAndInCharge: Zigzagged with Samuel Hayden, his robotic body eclipses the Doomguy in size and stands higher than a Hell Knight, [[NonActionGuy but he isn't interested in picking a fight directly]]. [[spoiler: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.
* KillEnemiesToOpen: The demonic presence has a lot of areas placed under lockdown, so they need to be cleared of demons in order to advance.
* LaserBlade: [[spoiler: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 CoolSword.]]
* LastChanceHitPoint: 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 BulletTime to escape your predicament.
* LeaningOnTheFourthWall: You're either playing as the SoleSurvivor of an ancient land invaded by Hell who swore eternal vengeance on the demons, or the PlayerCharacter of ''VideoGame/{{Doom}}'' and ''VideoGame/{{Doom II}}'' who became such a MemeticBadass over those games he's now some sort of [[EternalHero everlasting vengeance god]].
* LeParkour: The Doomguy is surprisingly agile, able to grip onto ledges to find secrets and hidden powerups.
* LevelEditor: The game lets you create [=SnapMaps=] that can be shared online.
* LifeDrain: The Siphon Grenade steals health from enemies in the blast radius and gives it back to the Doomguy.
* LighterAndSofter: 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''.
* LoweredMonsterDifficulty: Even with your downgraded weapon loadout, the Cyberdemon battle is a hell of a lot easier in the Tower of Babel classic map thanks to his strategy going back to [[AttackAttackAttack what it was in the original game]], with the rocket launcher being his only ranged attack.
* LudicrousGibs: A lot of the enemies can be easily gibbed. Enjoy a ''HELL'' of a bloodbath!
* MacGuffin: The Crucible.
* MacrossMissileMassacre:
** The Micro Missile mod for the Heavy Assault Rifle lets you fire six micro-sized missiles at a time. At full mastery it can fire as many darts as you have ammo without reloading.
*** 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.
* MadScientist: 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.
* MagikarpPower: The basic Pistol. While it's nowhere near as impressive compared to the other guns (and is practically obsolete once the player gets the shotgun), purchasing the pistol's upgrades make it a decent handgun. Then, if you take the time to complete the Mastery challenge for it (get 15 headshot kills, best done on the lowly Possessed), it one-shots Possessed Soldiers (something that takes 2 close-range shots from the shotgun to do) with no movement penalty. [[SubvertedTrope It's still no match for a basic shotgun though, and it takes a while to invest enough points to fully upgrade it. By the time that happens, the pistol still remains irrelevant]].
* MascotMook: 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.
* MinimalistCast: Besides the SilentProtagonist 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.
* MonsterShapedMountain: The Titan region in Hell is named after the giant, skeletal remains from Hell's greatest champion littering the landscape, [[spoiler:[[GreatOffscreenWar having been done in by the Doomguy at some point before the game.]]]]
* MookHorrorShow: 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.
* MythologyGag: ''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 [[https://i.redditmedia.com/zxycie_JTcnUT3JeWwnRE5-o14v_I3ytV7UkGOntXpk.jpg?w=644&s=5b0d7f45d3e3b09b3d8609f125ea1a7d illustration]] on Samuel's desk of [[spoiler: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 DoomDoors 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 [[Film/{{Doom}} Doom film]].
** The ''Doom II'' manual states that the Spider Mastermind isn't equipped with a plasma gun, and thank god for that. [[spoiler: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 [[spoiler: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, [[https://www.youtube.com/watch?v=ZmVOn4Qf_7k BFG Division]] contains a segment of the main riff from the original game's [[https://youtu.be/ETV9fPmieOM 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 [[https://www.youtube.com/watch?v=2U9pPMXqlA8 first see Olivia Pierce in person]] is a remix of [[https://www.youtube.com/watch?v=FMex4f8cwEY&index=5&list=PLAD2502F2CB75CC90 Suspense]] ([=E1M5=]) from the first game. The track that plays over the main menu, [[https://www.youtube.com/watch?v=nJI8JDnLH3Y 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 [[http://doomwiki.org/wiki/WAD .WAD file format]].
** There's an option to switch your weapon's onscreen position from the now-standard right corner to the center, mimicking the look of the classic games.
** The last note of the track that plays when you fight the Spider Mastermind is the first note of Spider Mastermind's theme from Doom 1 played backwards.
* NamesToRunAwayFromReallyFast: The forces of Hell, who collectively call themselves "The Slaves of Doom" are so terrified of the Doomguy they all know him as "[[RoaringRampageOfRevenge the Doom Slayer]]."
* NeckSnap: Doomguy does this on several Glory Kills. The game doesn't shy away from providing some [[SickeningCrunch appropiate sound effects]].
* NintendoHard: This game returns to the furious run n' gun gameplay style of the classic ''VideoGame/{{DOOM}}'' series, lacking conventions present in many other shooters released in its era such RegeneratingHealth and [[TakeCover 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 not a cakewalk, and defensive strategies like camping or turtling will only get you killed about 98% of time.
* NGOSuperpower: 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.
* NoFairCheating: 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.
* NoOSHACompliance: Counting how many absurdly flagrant safety violations the UAC is guilty of in their day-to-day operations is a fun little side game-- and an incredibly dangerous DrinkingGame, too. Of course, there's nothing in the game to suggest that the UAC operates with oversight of ''any'' kind, let alone regarding workplace safety.
* NoSell: 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.
* NostalgiaLevel: 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 [[spoiler:Icon of Sin]] makes a reappearance, still dead as a doornail.
** One of the levels in Hell features an adaptation of ''Dead Simple''.
* ObviouslyEvil: 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.
* OhCrap: The first time you are sent to Hell an ominous voice simply says "he is here" you can find runes about why the voice is not happy about it and there is a recorded conversation with Olivia where the voice is clearly angry she woke up the Doom Slayer.
* OneHitKO: The chainsaw now takes down anything in one hit, but it takes fuel to do it. Naturally, it doesn't work against bosses.
* OneHitPointWonder: One [[TimedMission Rune Challenge]] pits you against various demons from [[TheGoomba zombie and imp]] to [[LightningBruiser 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 [[BodyArmorAsHitPoints armor]] to survive.
* OneWordTitle
* PetTheDog: With how [[TheBerserker violent]] the Doomguy can be and [[ItAmusedMe how frequently he destroys expensive equipment for]] the [[{{Pun}} hell]] [[ItAmusedMe of it]], it's surprising that [[spoiler: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.
* PostPeakOil: 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.
* PoweredArmor: Doomguy's Praetor Suit, which according to the Slayer Testaments, [[spoiler:was created/improved by a demon who betrayed Hell and sided with him]].
* QuadDamage: Makes its ''Doom'' debut after being a staple item in id's ''VideoGame/{{Quake}}'', and shows up in both single-player and multiplayer.
* RatedMForManly: Oh HELL YES! Between the blood, the gore, the Glory Kills and the one-man onslaught against TheLegionsOfHell, 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 TheLegionsOfHell with all the guns and chainsaws you can carry, and how terrifying it would be ''[[HorrifyingTheHorror 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.
* RevisitingTheRoots: 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.
* RewardedAsATraitorDeserves: [[spoiler: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 [[CameBackWrong a demon]] because "the wages of treachery are suffering".
* RoaringRampageOfRevenge: What the Doomguy's motivation for fighting against Hell is hinted to be. Codex entries and The Slayer's Testament imply [[spoiler: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]].
* RocketJump: You can get a boost for your jumps by using the Gauss Cannon's recoil to get a little more airtime.
* RocketTagGameplay: 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.
* SaveScumming: 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.
* {{Satire}}: Yes, seriously. The fact that, in the future, humanity chose to take energy from ''hell itself'' rather than any other renewable energy source should make this obvious. In addition, the Argent Facility having several clear human rights violations and questionably ethical experimentation on demons brings to mind shady corporations that treat their employees like crap. In the end, the UAC is every real-life MegaCorp taken UpToEleven.
* SceneryGorn: 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. [[UpToEleven Usually all three.]]
* SceneryPorn: 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 [[JustForPun one hell of an impression.]]
* SealedGoodInACan: The Doomguy. [[spoiler: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.]]
* SecondaryFire: Some weapon mods give secondary firing modes, like an explosive shot for the shotgun or mini-missiles for the heavy assault rifle.
* SecretLevel: 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.
* SelfImposedChallenge: [[https://www.youtube.com/watch?v=_S9G8tvfCNI This guy]] beats [[FinalDeathMode Ultra-Nightmare]] using ''only the pistol''.
* SequelHook:
** After you defeat [[spoiler: Olivia Pierce]], you are tethered back to Mars by [[spoiler:Hayden]], [[WellIntentionedExtremist who still believes that he's in the right]] before snagging [[{{MacGuffin}} the Crucible]] from the Doomguy and, [[YouHaveOutlivedYourUsefulness rather than kill him]], decides to send him elsewhere to prevent him from interfering with his plans, [[{{Cliffhanger}} but remarking that they'll meet again soon enough...]] In this instance [[spoiler: Samuel]] has no choice, killing the Doom Slayer ensures that, should something as catastrophic as this ever happens again, no one who can stand up to the demon invasion will be left. Also? It might not be possible.
*** The game also tantalizes you by [[spoiler: showing Hayden rip the Crucible off your person ''and ignite it like a lightsaber into a giant hellish energy blade'' before walking off into the darkness and rolling the credits.]]
** The Doomguy [[spoiler:saves a backup of VEGA before destroying him]].
* SetAMookToKillAMook: 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.
* ShieldBearingMook: Possessed Security have large shields that defend them from frontal attacks.
* ShoutOut:
** As with the original, one of the difficulty settings is "[[Literature/AClockworkOrange Ultra-Violence]]".
** If you die by falling into a lava pit, the Doom Marine will [[Film/Terminator2JudgmentDay give a Terminator-esque thumbs up]].
** The illustration that you can find on Samuel Hayden's desk of [[spoiler:the Doomguy fighting demons]] is in the style of the Ark of the Covenant's woodcut illustration in ''Film/RaidersOfTheLostArk''.
** The Pistol and BFG-9000 act very similarly to ''VideoGame/QuakeII'''s Blaster and BFG 10K, respectively. The Pistol's visual design also resembles the Dominator pistol from ''Anime/PsychoPass''.
** Just as in VideoGame/QuakeIIIArena, picking up extra armor that surpasses your default meter will decay over time.
** One of the multiplayer taunts is [[Series/TheFreshPrinceOfBelAir Carlton's dance.]]
** In one of the Hell levels, it's possible to find a skeleton with a [[VideoGame/TheElderScrollsVSkyrim horned helmet and an arrow through its knee]].
** One of the Hell levels also has the helmet of VideoGame/CommanderKeen, 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 [[VideoGame/{{Fallout}} Vault-Tec]] logo on it.
** An early collectible is "Vaultguy", Doomguy with his armor painted like a Vault suit. A couple of the late-game collectable figurines are [[VideoGame/CommanderKeen Keenguy]] and [[{{VideoGame/Quake}} Quakeguy]]. [[VideoGame/QuakeIIIArena Phobos]] is there as well.
** The demons ApocalypticLog is titled the Music/{{Slayer}} Music/{{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''.
** The hidden ''Super Turkey Puncher 3'' arcade cabinet has a logo that's designed to resemble that of ''VideoGame/StreetFighterAlpha 3''.
** One of the Cyberdemonic armors from the multiplayer mode has [[Anime/MobileSuitGundam a spiked pauldron on its left shoulder and a small shield on its right]].
* ShowsDamage: Some enemies can have limbs blown off without actually being killed. [[spoiler:Olivia Pierce as the [[OneWingedAngel 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.]]
* ShutUpHannibal: Any justifications Hayden comes up with are ignored by the Doomguy. Doomguy even takes the time to listen to his excuses for why mining Hell is a good idea before smashing the equipment to show that he does hear Hayden, he disagrees.
* SuspiciousVideoGameGenerosity: 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.
* StaticRoleExchangeableCharacter: As with StealthSequel, it's made ambiguous as to ''what'' this game's Doomguy is. [[spoiler: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.]]
* StealthSequel: It's implied that the Doomguy in this game [[spoiler:is actually the very same one from the original two ''Doom'' games]].
* StylisticSuck: 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).
* TranquilFury: How else can you describe a man who carves through the forces of hell without uttering a word.
* TurnedAgainstTheirMasters: The Revenants, Mancubi, and Cyberdemon were all created by the [=UAC=] to be used as weapons. Being TooDumbToLive, they seem to have engaged in mass production before even having figured out a way to control the damn things.
* TheReasonYouSuckSpeech: [[spoiler: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.]]
* TheUnfought: [[spoiler:Samuel Hayden]].
-->[[spoiler:'''Samuel Hayden:''']] I am not the villain in this story. I do what I do because there is no choice.
* TeethClenchedTeamwork: 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.
* TitleDrop: The demons call Hell "Doom", with their collective forces the "Slaves of Doom", and the Doomguy himself known as "the Doom Slayer". [[DoomyDoomsOfDoom Really, the word "doom" is all over the place in this game.]]
* TookALevelInBadass: 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 Soldier is a good deal tougher and hardier than the classic Zombieman, and now packs a plasma weapon instead of a puny rifle.
** 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 [[LightningBruiser 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 GlassCannon that gradually became passé as time went on, got a pretty significant buff that turns them into {{Lightning Bruiser}}s with the bonus of [[DeathFromAbove being able to fly and smoke you out with]] [[MacrossMissileMassacre 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, [[{{Expy}} 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 DamageSponge 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.
** [[spoiler: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.]]
* TranquilFury: Doomguy never speaks, but still turns the forces of hell to LudicrousGibs. Also seen with Samuel Hayden, where he [[ShutUpHannibal regularly destroys Hayden's means of communication]] but never directly attacks the head of the UAC.
* TurnsRed: Inverted [[spoiler:with the Spider Mastermind, which becomes increasingly bruised and crippled after a considerable number of hits are landed on it.]]
* {{Unobtainium}}: The [[AppliedPhlebotinum Argent energy]] used to power everything drives a portion of the story, [[spoiler:being from Hell itself and all.]]
* UnstoppableRage: 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 [[TranquilFury demeanour]] [[NoHoldsBarredBeatDown towards]] [[TheresNoKillLikeOverKill any demon]] in the present day showcases very clearly.
* UpToEleven: 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.
* UtopiaJustifiesTheMeans: 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''.
* VideoGameCrueltyPotential: Taking numerous pages from ''VideoGame/BrutalDoom'', 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.
* WaveMotionGun: 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.
* WeCanRebuildHim: 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.
* WellIntentionedExtremist:
** Both [[TheQuisling Olivia Pierce]] and [[{{Cyborg}} Samuel Hayden]], the former working with Hell to bring about a new world for mankind and the latter [[spoiler:wanting to utilize Hell for [[{{Unobtainium}} its resources]] to usher in a better world for mankind as well. Although in Olivia's case it [[TheCorruption eventually degenerates]] into "Obtain God-like power".]]
** Doomguy fits this, considering that his world was destroyed by TheLegionsOfHell, it seems justifiable in wiping out every last trace of it when he reawakens to try and stop Earth from suffering the same fate.
* WhatTheHellHero: 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.
* WhenAllYouHaveIsAHammer: 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.
* WorldOfBadass: The main character is an immortal butcher machine. The CorruptCorporateExecutive 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 [[spoiler: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 PowerArmor''. Everyone else has GUNS grafted to their arms and/or mouths.
* WorthyOpponent: 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.!
