7''Doom'' (stylized as ''DOOM'') is the fifth main installment in the ''Franchise/{{Doom}}'' franchise, developed by Creator/IdSoftware and published by Creator/{{Bethesda}} for the PC, Platform/PlayStation4, and Platform/XboxOne on May 13, 2016. It was ported to the Platform/NintendoSwitch on November 10, 2017.

9You play as a [[HeroicMime silent]], unnamed SpaceMarine who wakes up naked in a creepy stone coffin surrounded by zombies. After slaughtering them and acquiring a suit of PoweredArmor from an equally-creepy sarcophagus, you discover you're inside a Union Aerospace Corporation facility on Mars in the middle of a [[HellOnEarth demonic invasion]].
10
11What were you doing in a coffin? ''Irrelevant.'' Why are demons invading Mars? ''Who cares.'' You're a [[ComicBook/{{Doom}} berserker-packin' man and a half]] who's here to ShootEverythingThatMoves until TheLegionsOfHell are obliterated.

13''[[MythologyGag Rip and tear]], until it is done.''

15Originally announced in 2008 as ''Doom 4'', the game was designed to be a GenreThrowback to the early days of {{First Person Shooter}}s -- back when guns didn't need reloading, cover was for cowards, 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.
16
17Several months after ''Doom'' (2016) was released, Creator/ZenStudios developed and released a [[DigitalPinballTable virtual pinball adaptation]] of the game as part of the ''Bethesda Pinball'' collection, available as part of [[VideoGame/ZenPinball ''Zen Pinball 2'', ''Pinball FX 2'' and ''Pinball FX 3'']] and a separate app on smartphones.

19Has a direct sequel, ''VideoGame/DoomEternal'', which was released on March 20, 2020.
20----
21!''Doom'' (2016) provides examples of:
22
23[[foldercontrol]]
24
25[[folder:#-D]]
26* 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. And once you've bagged all of those, chances are you still have to complete some of up to two mastery challenges per weapon. The game keeps track of most categories through various achievements.
27* AbnormalAmmo: Most guns avert this despite incorporating Argent power technology one way or another, but the [[EmergencyWeapon pistol]] makes up for it by directly converting Argent energy into gel bullets that behave more or less like "real" slugs. It's also a neat explanation as to why the little thing has [[BottomlessMagazines infinite ammo]].
28* AbsurdlyHighLevelCap: In multiplayer, there are 600 total levels the player can advance through, with 50 levels scattered across 12 epsilons.
29* ActionBomb:
30** Lost Souls fly straight towards you, kamikaze-style.
31** Possessed engineers don't blow themselves up on purpose, but they're melee enemies with a volatile gas tank fused into their torso, so the result is basically the same [[TooDumbToLive if you let them get too close and then shoot them without realising what exactly you're doing there]].
32* 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.
33* 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.]] Most of this is due to Olivia Pierce turning the UAC Division on Mars into her own cult, but Samuel Hayden essentially let her do whatever she wanted, as long as he got results (i.e.: working Argent energy).
34* 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 [[PutOnABus 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.]]
35* AggressivePlayIncentive: The game has famously utilized a number of mechanics to entice players to aggressively chase demon enemies throughout the levels instead of taking potshots at them from cover. These range from the obvious [[FinishingMove Glory Kills]], which require players to get into melee range but restore some of their HitPoints, to the subtle, like the ranged enemy AI typically backing off as the player approaches, putting the latter in a hunter mindset.
36* AmmoUsingMeleeWeapon: The Chainsaw requires rare fuel to offset its immense power.
37* AndShowItToYou: The Glory Kill for the Mancubus involves ripping its heart out of its bloated gut and then shoving it down its mouth.
38* 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.]]
39* AntiFrustrationFeatures:
40** 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.
41** The game allows you to return to previously beaten levels, and any upgrade items you find that you missed before are carried into the current level.
42*** Your progress towards combat and level challenges is saved even if you die and have to reload a previous checkpoint, so you only have to succeed at particularly difficult challenges once.
43** During Rune Trials where the objective is to kill every enemy in the arena, when you are down to the last few the demons will be highlighted for you, including through walls, as a way of reducing LastLousyPoint situations.
44** When it's time to glory-kill the FinalBoss with the BFG, the move can be performed regardless of whether the weapon has any ammo left or not, leaving you free to apply your full stockpile to the thing's face in the grueling battle.
45* AlternateFire: Each weapon except for the Chainsaw, Super Shotgun, and BFG-9000 can have one of two GunAccessories installed.
46** The pistol, Heavy Assault Rifle, Shotgun, Plasma Rifle and Gauss Cannon 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 Gauss Cannon charges an immensely powerful shot with generous SplashDamage. The pistol is charged by holding down the alt-fire button, gradually gaining power.
47** 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.
48** The HAR and Gauss Cannon can alternatively be equipped with a sniper scope.
49** 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.
50* 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's Testaments, which tells the tale of the Doomguy's nigh-unstoppable rampage through their realm and [[HorrifyingTheHorror how they're all terrified of him]].
51* AreTheseWiresImportant: Doomguy's preferred method for dealing with Argent Energy equipment, despite Hayden's demands that he use utmost care.
52* ArmCannon: Possessed Soldiers and Security have guns fused to their right arms. Hell Razers shoot beams out of their right arms.
53* ArtifactOfDoom: The Crucible.
54* 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 (found a dead end you can camp from? Have fun with the heavily-armored [[BullfightBoss Pinkies]] about to charge in after 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...
55* ArtificialStupidity:
56** 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.]]
57** Some enemies, especially the [[GameplayAndStoryIntegration dumb Possessed]], think nothing of lumbering to their death in a BottomlessPit or accidentally hitting an explosive barrel in their zeal to get to you while you're below them.
58* AscendedMeme:
59** The opening cutscene quotes the phrase "Rip and Tear" from the ''ComicBook/{{Doom}}'' comic. However, whereas in the comic it came across as comically over-the-top, in ''Doom 2016'' it comes across as ''absolutely badass'' and sets the tone for the entire rest of the game.
60** Doomguy in the Doom comic called the chainsaw "the Great Communicator", and "communicated" his desire to have his enemies' guns via the weapon. What's the best way to get ammo back in this game? Use the chainsaw to rip an enemy in half.
61** There are a huge number of trophies quoting the ''ComicBook/{{Doom}}'' comic.
62** One fan name for the Doomguy, "The Doom Marine," is now what UAC calls him in-universe.
63*** Likewise the "Demon" enemy returns and is now officially called by his fan name "Pinky".
64** The achievement for killing the Cyberdemon is called [[CaptainObvious/VideoGames "Shoot it until it dies."]], referencing the "Protip" meme.
65** 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.]]
66** At the beginning of the game, the forces of Hell [[SealedGoodInACan imprisoned]] the Doom Slayer by dropping a temple on top of him. This isn't the first time in ''Doom'' history a space marine has been trapped by [[Fanfic/DoomRepercussionsOfEvil the ceiling falling on him.]] The game proper also starts with him awakening from his coffin, [[AndThenJohnWasAZombie which may or may not be a metaphor for something.]]
67* AssKicksYou: Execute a Glory Kill on a Pinky from behind and you will rip out its entire rump, smacking the demon across the face with it.
68* 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.
69* AwesomeButImpractical:
70** The Tactical Scope for the Heavy Assault Rifle. On paper, having a scope to deal with distant foes is a good thing, but in Doom's frantic, close combat arenas, the minor bump in damage is negligible in comparison to the firepower and mobility of the [[MacrossMissileMassacre Micro Missile Launcher]].
71** The Mobile Turret upgrade for the Chain Gun. Sure, you now fire three times as fast and can down enemies in a couple seconds of sustained fire. However, you will also burn through your entire ammo supply in those few seconds, with no real improvement on your damage per bullet spent. That said, mastering the upgrade removes the overheating, which in combination with the [[BottomlessMagazines Rich Get Richer]] rune shifts the weapon right into game-breaking territory.
72* 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."]]
73* BadassCreed: "Rip and Tear, until it is done"
74* BagOfSpilling: Mostly averted; weapons, runes, and upgrades are carried over between levels. However, the colored keys and skulls you'll collect to unlock doors must be gathered fresh each time.
75* {{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.]]
76** 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.
77* 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.]]
78* 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.]]
79** It is also implied that God exists in this game, as it is stated [[spoiler:in the Slayer's Testaments that Doomguy]] was endowed with supernatural fighting ability by an angel.
80* BigRedDevil: Imps and Barons of Hell, hell-spawned demons with red skin and horns.
81* BittersweetEnding: One of the ''very'' bittersweet sort, near bordering on a downer. [[spoiler: After ripping and tearing his way across Mars and Hell, the Doom Slayer shuts down the Well, closes the portal Pierce ripped open, and kills Pierce in the process. However, everyone in the UAC facility is dead except for Hayden, and the Slayer had to overload VEGA's core to reach the Well. Hayden also takes the Crucible from the Slayer, planning to use it to continue his research on Argent energy; he concedes that while the Slayer might have a point about killing every last demon and preventing the UAC from exploiting Hell, Hayden can't just pull the plug since Earth will face an impossible energy crisis if he does. The only silver linings here are that the Slayer made a backup of VEGA and that Hayden doesn't kill him (and probably can't), simply content to teleport the Slayer away so he won't interfere with Hayden's plans and promising they'll see each other again if another demonic invasion happens. [[VideoGame/DoomEternal Which it does.]]]]
82* TheBerserker: The Glory Kill and Berserk artifact mechanics encourage you to run through enemy attacks to rip demons limb from limb.
83* 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.
84** 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. Or the bit where he chants in BlackSpeech with the same calm and cheerful tone.
85** The notifications about a demonic incursion being in progress can cause chuckles, especially the part about "demonic presence at unsafe levels". What, do tell, would be ''safe'' demonic presence levels other than zero?
86* BodyArmorAsHitPoints: Armor in this game acts like bonus health; any damage you take is taken out of your armor meter first.
87* 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. Then there are the possessed engineers, who have ''explosive gas tanks'' fused into their torsos.
88* BoomHeadshot: Aiming for the head will deal amplified damage-and cause the enemy's head to [[YourHeadASplode pop like an overcooked burrito]] on death. The assault rifle's scope mod can be upgraded to deal additional bonus damage with headshots on top of that. Fully mastering the pistol, assault rifle, and Gauss cannon also requires killing a bunch of enemies with headshots while specific weapon mods are active[[note]]The pistol requires fifteen headshots with the Charged Energy Shot, the assault rifle requires fifty headshots with the Tactical Scope, and the Gauss cannon requires five headshots on Hell Knights with the Precision Bolt[[/note]]. As a loading screen puts it, "If an enemy has a head, it's a weak spot", which applies to every enemy (except the Cacodemon, which is nothing ''but'' a head).
89* BoringYetPractical:
90** The Gatling Rotor for the Chaingun. Compared to the [[StuffBlowingUp Micro-Missile Launcher]] and the [[MoreDakka Mobile Turret]], the Gatling Rotor seems rather mundane. However, it allows you to keep your Chaingun ready to fire at an instant as well as having an upgrade that increases the damage when the mod is used.
91** 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!
92** It might be a bit of a stretch to call the iconic Super Shotgun "boring", but it's one of the only weapons aside from the pistol, chainsaw, and BFG 9000 you don't get mods for. But the raw power of the gun itself more than makes up for the lack of secondary fire options. Its upgrade for completing its challenge falls under this trope compared to the other guns, too; It allows the Super Shotgun to be fired twice before reloading, which can absolutely murder demons up close.
93** Fully upgrading the basic Pistol might seem like a waste of precious upgrade points, as its only upgrade increases the efficiency of its charged shot and mastering it requires you to pop off headshots with it. Once mastered, though, it becomes a really consistent mid to long-range weapon, with a fast and accurate projectile that, at full charge, can down minor enemies with a bodyshot and even stun-lock larger ones like Hell Knights and Revenants.
94** The Ammo Boost rune, while it doesn't match the Rich Get Richer in terms of sheer ammo abundance, is more practical to utilize as it doesn't require the Doom Slayer to maintain 100 to 75 points of armor to actually use it. It also has the benefit of having the chance to spawn BFG ammo once upgraded.
95** In terms of equipment, the Hologram is this compared to the frag and siphon grenade. All it does is drop a hologram copy of Doomguy wherever you stand, with it firing a few plasma rounds and, more importantly, drawing enemy aggro to it. While it doesn't do immediate damage or heals you like the latter two respectively, the hologram can draw enemies away and it doesn't expire until the timer ends, thus indirectly saving you some health and armor while letting you focus on certain enemies uninterrupted. With the rune to increase equipment effectiveness and Praetor upgrades to lower the charge time, it'll let you throw out a Hologram effectively 100% of the time and prudent usage of it ensures an easier battle, especially on Nightmare difficulty where the value of its drawn aggro is greater than more damage or healing from the frag and siphon grenade, respectively. Of course, nothing's stopping you from using all of them interchangeably.
96* 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.
97* BorrowingFromTheSisterSeries: Borrows the QuadDamage powerup from sister Id Software franchise ''VideoGame/{{Quake}}''.
98* BottomlessMagazines: In a return to ''Doom'' and ''VideoGame/DoomII'', 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.
99* 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.
100* BroadStrokes: The events of ''Doom'', ''Doom II'', and ''VideoGame/Doom64'' 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.
101* 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.
102* 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.
103* 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]]
104* 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.]]]]
105* CannedOrdersOverLoudspeaker: All over the place in the UAC facilities.
106* 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, alhough Pierce is a blatant [[DistaffCOunterpart gender-flipped]] {{Expy}} of Dr. Malcom Bertruger from ''Doom 3.''.
107* 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 every level. That isn't even going into the details of the "Rich Get Richer" rune.
108* CapRaiser: Argent Cells, when acquired, boost the player's choice of stat they boost, out of max health, armor, or ammo capacity. Each can only be boosted so many times before they can't anymore and are removed from being selected.
109* 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.
110** 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.
111* ChargedAttack: Most of the weapon mods work like this in some way.
112* CherryTapping: By the mid-game, the pistol has been long outclassed by other weapons and it functions solely as an EmergencyWeapon, and even then only until you get one of the frequent minor ammo drops. However, it still maintains some tactical value even late in the game for setting up weaker enemies for [[FinishingMove Glory Kills]]. More dangerous enemies will generally be taken out with extreme prejudice, but more powerful weapons tend to be overkill for minor foes, so the pistol can help turn every little enemy into a source of health and ammo drops if the player is willing to handicap themselves a little.
113* ColorblindMode: This game has its colorblind settings just filter the game to how it would look like if you had the disability rather than adjusting it to be more useful to such players, making them more suitable for challenge runs/curiosity than actual assistance, though it doesn't require hue recognition that much anyway (green lights often indicate progress against many reddish backdrops, but they ''are'' glowing and thus stand out well enough anyway).
114* ColorWash: Part of the game's rendering process applies a red filter over the screen.
115* 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.
116** When meeting in person and if the player decides to shoot, Samuel will simply say "Save your ammunition".
117---> '''Samuel Hayden:''' [[DeadpanSnarker Your affinity for guns is apparent]]. I'm confident you'll find [[{{BFG}} something useful]] there as well.
118* 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]] "[[GodhoodSeeker 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.]]
119* 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. [[spoiler: Or, rather, he ''does'' pay heed, but decides that it just isn't worth the risk.]]
120* CreativeClosingCredits: The end credits begin with fly-bys of 3D stills or lightly-animated dioramas of various scenes from the campaign and other stuff (such as the Doom Slayer's arsenal laid out) as the staff members' names are mapped into the environments, including a humorous scene of one of the Slayer dolls facing off against a Pinky. The dynamic credits end with a perfectly recreated interpretation of the original ''Doom''[='s=] famous cover art of the Slayer standing on a mountain of Imps before tossing the one grabbing him into the air and blasting him to bits with the Combat Shotgun.
121* CruelAndUnusualDeath: The Glory Kills all involve inflicting some extremely brutal and painful looking death on demons in creative fashion. They include (but are not limited to) crushing enemy skulls, yanking out a Cacodemon’s Eye, feeding a Mancubus it’s own bomb, and yanking an enemy’s limb off before home-running their body with it, all after blasting them with enough heavy gunfire to stagger them.
122* CrypticBackgroundReference: There is apparently some major energy crisis going on as the humans have ended up having to open portals to Hell to tap into Argent Energy, a seemingly infinite (or effectively infinite) energy source. The drawback being, of course, you also have demons trying to invade our dimension.
123* {{Cult}}: After succumbing to demonic corruption, Olivia Pierce has turned the UAC into a secretive demon cult.
124* {{Cyborg}}:
125** 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.
126** 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.
127** 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''.
128* 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.
129** Oldschool players and classic Doom players were in for a surprise as the assigned number keys for the weapons are different and the Shotgun and Super Shotgun are put into different number instead of the same number.
130** 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.
131* DarkIsNotEvil: The Wraiths found in the last level might look demonic even before they were corrupted but the Codex reveals they were Argent D'Nur's first life forms that the people worshiped as gods before they were corrupted by Hell .
132* 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.
133* 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.]]]]
134** This is also how the demons conquered [[spoiler:Argent D'Nur. The Night Sentinels were repelling the forces of Hell rather effectively, until one among their number betrayed them all in exchange for the resurrection of his son. When the source of the Sentinels' power was corrupted, the demons held up their end of the bargain... by bringing the Betrayer's son back [[CameBackWrong as a demon]].]]
135* DemonOfHumanOrigin: [[spoiler:Olivia Pierce]] opened the Hell Portal for good to allow the demonic forces to invade Mars in exchange for her own elevation into godhood. It turns out that this means ripping out her original personality and forcefully transforming her into the [[FinalBoss Spider Mastermind demon]].
136* 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.
137* DevilButNoGod: Averted, but only just barely. In a game positively dripping with demons, "seraphim" are mentioned a single time in one of the Testaments of the Doom Slayer. Specifically, they altered the Doom Slayer and is one of the reasons he's so unstoppable.
138* DifficultButAwesome: The Rocket Launcher's Remote Detonation mod. It is undoubtedly a harder sell compared to the Lock-On Burst, which has far more obvious applications and raw damage output. With practice however, Remote Detonation turns out to be much more useful for crowd-control and for reducing your missed shots (as missing with the Rocket Launcher is extra-risky given the wait between shots), and the mod especially shines once you unlock its Mastery. Now detonating the rocket doesn't take the rocket with it, giving you effectively two rocket explosions for the price of one point of ammo, compared to Lock-On Burst using up three per shot for a similar result.
139* DistaffCounterpart: Olivia Pierce is basically [[VideoGame/Doom3 Dr. Betruger]] with no Y chromosome.
140* DoubleJump: Doomguy eventually comes across some thruster boots that let him jump an additional time in the air.
141* DualBoss: Barons of Hell, if not alone, will usually appear in pairs. [[spoiler:The second phase of the Hell Guard battle has you fighting two slightly-weaker Guards simultaneously]].
142* DraggedOffToHell: Happens quite a few times, [[spoiler:though the last few are a deliberate effort so you can break into Hell.]]
143* DramaticGunCock: Doomguy pumps his shotgun right as he's about to get off the elevator once the first mission, following the title screen. Also a case of MickeyMousing, since the cock punctuates the last two guitar riffs from "At Doom's Gate".
144* 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.
145* DrivenToSuicide: One of the codex entries on the Foundry level implies that the facility's casualty rate from "accidents" was notoriously high until the [=UAC=] thought to institute "re-education" and therapy sessions for low level workers. Given what kind of activities the company was involved in, spiritual and mental health issues are practically a given.
146[[/folder]]
147
148[[folder:E-L]]
149* EarlyBirdCameo: The Heavy Machine Gun appeared in the Steam version of ''[[VideoGame/QuakeIIIArena Quake Live]]''.
150* EasterEgg:
151** Music/MickGordon was bored working on a particular track one day, looking for inspiration he watched a video on Satanic messages hidden in rock music, and became inspired to bury the number "666" and a pentagram into the audio track. [[https://youtu.be/U4FNBMZsqrY?t=2325 As he explains here, you can find it with a spectragraph.]]
152** In The Necropolis, hidden in the level is a balloon which says "Happy birthday!" with a skeleton with a party hat next to it. You can pop the balloon and either receive applause or jeering. The only explanation given by WordOfGod is that this is an inside joke within id's development team.
153** Also from the Necropolis, one toy can be collected in the Icon of Sin room, [[MythologyGag by using the tried and true technique of shooting a rocket in its brain.]]
154* ElectronicSpeechImpediment: [[spoiler:VEGA, as you're shutting it down in the second-to-last level]].
155* 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.
156** In bits of the lore it's said their authority was absolute, answering only to the highest ranking UAC members, so AuthorityEqualsAsskicking, apparently.
157* 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.
158** 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.
159** 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.
160** 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.
161* EstablishingCharacterMoment: The first level of the game establishes the particulars of the Doom Slayer's personality pretty quickly: 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''.
162* EstablishingSeriesMoment: The opening level also serves as a statement of purpose by the game on its intentions to be a GenreThrowback to earlier ''Doom'' games and love letter to their fans. The opening dialogue promises [[OneManArmy you will be scarier than the demons]], then InUniverse quotes the famous {{Memetic|Mutation}} "rip and tear" line from the {{Narm}}y 90s comic. The game then has the character [[RatedMForManly killing a zombie with his bare hands]] in 15 seconds, [[StoryToGameplayRatio puts you in control with a gun]] in 20 seconds, starts a VoiceWithAnInternetConnection's InfoDump only to then immediately skip it on its own within two minutes, and within the first three minutes [[ShotgunsAreJustBetter has given you a shotgun]].
163* EvenEvilHasStandards: The demons may be evil but their writings indicate a loathing of betrayers, referring to them as "wretched". [[spoiler:Humans who betray their worlds to side with Hell are typically RewardedAsATraitorDeserves, such as in the case of Olivia and the mysterious Betrayer of Argent D'Nur.]]
164* EverythingFades: Demon corpses and gibs disintegrate after a few seconds. As with ''Doom 3'', this was likely meant to ease up on memory.
165* EvilBrit: Olivia Pierce has an English accent, and is the game's BigBad.
166* EvilCripple: Olivia Pierce's odd appearance is explained in the codex as an elaborate workaround for debilitating scoliosis. It notes that the exoskeleton she wears must be quite painful, but she refused any medication. It also notes that she'd be unable to walk without it.
167* 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. However, exploiting Hell was the main goal; everything related to Hell otherwise such as weaponizing demons and the foundation of the cult was all Pierce, though the board was content to let her do whatever she wanted as long as she produced results until it became too much for Hayden to ignore.
168* 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. Hell itself is equal parts FireAndBrimstoneHell and BloodyBowelsOfHell, while areas in the mortal plane dominated by Hell end up being covered in MeatMoss, created by the Possessed as they cobble together corpses to create Gore Nests.
169* 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.
170* 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.
171* EvolvingWeapon: This game introduces the ability to upgrade your weapons using "Weapon Points" which are earned by killing Demons (5 points per-level), finding secrets (1 point for 50% completion and another for 100%), and completing challenges (3 per mission). Most weapons can be equipped with one of two Mods that grant alternate firing modes, each of which can be switched around mid-combat and have their own set of upgrades with a "Weapon Mastery" available for unlocking every upgrade for a mod then completing a challenge.
172** '''Combat Shotgun''': Charged Burst (fires 3 shots in rapid succession, the Mastery ability gives you a damage boost for your next attack if you hit all three shots) or Explosive Shot (fires a grenade, Mastery turns it into a cluster bomb if you score a direct hit).
173** '''Heavy Assault Rifle''': Tactical Scope (a scope that grands improved headshot damage and can pierce enemies. The Mastery ability is a simple damage boost) or Micro Missiles (fires up to six bolts which embed in their targets before exploding, Mastery lets you continuously fire these missiles without reloading).
174** '''Plasma Rifle''': Heat Blast (firing the weapon fills up a heat sink, which when full can be released to damage Demons around the player. Mastery allows the heat sink to fill up automatically over time) or Stun Bomb (a grenade which stuns enemies. Mastery causes enemies killed while stunned to also stun enemies around them).
175** '''Rocket Launcher''': Lock-On Burst (fires a burst of three rockets which track their target. Mastery allows multiple enemies to be targeted at once with the rockets being split between them) or Remote Detonation (allows you to control a rocket's detonation in mid-air. Mastery results in this detonation not destroying the rocket, essentially giving you two explosions with one shot).
176** '''Gauss Cannon''': Precision Bolt (adds a scope which allows the weapon to be charged. Mastery causes targets to explode upon death) or Siege Mode (adds a stance which immobilises the player, but fires an extremely powerful bolt which pierces enemies and explodes upon impact. Mastery allows you to move while using it).
177** '''Chaingun''': Gatling Rotator (allows you to manually wind up the weapon, with Mastery increasing damage when at max speed) or Mobile Turret (doubles rate of fire but causes the weapon to overheat, with Mastery removing the overheating mechanic).
178** Among weapons without Mods, the '''Pistol''' has a Mastery which increases the damage of its charged shot, while the '''Super Shotgun''' earns the ability to fire two shots before reloading.
179* ExactWords: The DealWithTheDevil that frames the story's start.
180** For Olivia Pierce, [[spoiler:she wanted power, and was ''painfully'' transfigured into the Spider Mastermind.]]
181** 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''.]]
182* 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 [[AllThereInTheManual hidden in audio logs and database entries]].
183* ExplodingBarrels: All over the place, and they're colored red too. [[spoiler:The acid barrel sprites appear in the classically-styled areas and maps]].
184* 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...
185* 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.
186* {{Expy}}:
187** Olivia Pierce is one to [[VideoGame/{{Doom 3}} Malcolm Betruger]].
188** The Summoner enemy is the Arch-Vile in all but name.
189*** Further proving the point, its model name, as seen in the Resources Explorer, is "archvile".
190* ExtremelyShortTimespan: The game notably has few, if any, indications of time passing, with most in-game events occurring essentially in real time. This means that the Slayer wakes up and utterly decimates the combined forces of hell in, roughly, a few hours.
191* EyelessFace: A surprisingly large percentage of Hell's demon roster lack obvious eyes, including but not limited to all five subspecies of Possessed, Hell Razers, Hell Knights, and Summoners.
192* 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.
193* 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.]]
194* FallDamage: Mostly averted, in keeping with the game's arcade-y nature. The Doom Slayer's [[PoweredArmor Praetor Suit]] incorporates a system called Impact Compensation that negates all non-lethal fall damage. Dropping a very long distance stuns him for a few seconds while he recovers from the impact (in a pose that resembles a ThreePointLanding no less), opening him up to indirect fall damage when enemies exploit his momentary helplessness, but only ''really'' deep falls can kill him, which usually only happens if you screw up during platforming sequences. The stun on landing can also be avoided through timely deployment of his DoubleJump boots in midair.
195* 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.]]
196** [[spoiler:The Wraiths, which lie within the Argent D'nur, were originally noble (though apparently [[GoodIsNotNice mercurial]]) 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.]]
197* 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 [[SilentSnarker personality]] of his own.
198* FinalBoss: [[spoiler:Olivia Pierce, who transforms into [[BigCreepyCrawlies the Spider Mastermind]], is the final enemy you face in the game.]]
199* FinalDeathMode: Playing on Ultra-Nightmare means that you only have one life. If you die, it's back to the beginning. The places you died previously are marked with the Doom Marine's helmet and a hologram describing the exact time you died and what enemy killed you.
200* 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.]]
201* FirstPersonDyingPerspective: All of the Doom Slayer's deaths in the campaign take place from his POV.
202* FromBadToWorse: As if the standard Pinky demons with their heavy armor and devastating charge attack weren't bad enough, you later encounter Spectres, which are the same fun package plus [[VisibleInvisibility being really hard to spot]].
203* 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.
204* FullHealthBonus: The "Rich Get Richer" rune grants the Doom Slayer BottomlessMagazines for all standard weapons as long as his [[BodyArmorAsHitPoints armor]] is at 100 or higher (or 75 with the upgrade).
205* GameBreakingBug: Some players have reported accidentally activating Developer Mode, which corrupts saves and disables achievements or multiplayer.
206** There's another bug where all NPC audio goes away. The game is surprisingly coherent without it.
207* GameplayAllyImmortality: Attempting to shoot Samuel Hayden when you finally meet him will simply have his personal DeflectorShield absorb the attack and him telling you to save your ammo.
208* 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.]]
209* GenreThrowback: Way back to original Doom and the first generation of first-person shooters. Kill anything that moves, worry about the plot later.
210** 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.
211** It also makes up for certain throwbacks by straight-up replacing how they might work in a modern game. There's no sprint meter because your default run speed is incredibly fast. The standard "reload" button pulls out the chainsaw, which makes enemies explode into ammo fountains. There's no aim-down-sights because left trigger is an alt-fire (and guns are actually really accurate, so you don't ''need'' aim-down sights).
212* GlassCannon:
213** 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. This is mitigated as the game goes on and the player upgrades their maximum health and armor.
214** [[ActionBomb Lost Souls]] deal massive damage but can be killed with only a few hits from any weapon including the humble pistol.
215* 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:
216-->'''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]].
217* GoneHorriblyRight: The [[TooDumbToLive researchers]] attempted to give the [[spoiler:Cyberdemon]] an Argent Energy generator to help it automatically recover any damage done to its 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.
218** From Samuel Hayden's perspective, releasing the Doom Marine from his captivity to defeat the demons works, but results in [[spoiler:the argent energy collection system being totally destroyed. Considering humanity was saved from a devastating energy crisis by the [=UAC=]'s exploitation of Hell, the Doom Marine's disregard could cause widespread societal disruption on Earth. It is for this reason that Samuel eventually betrays the Doom Marine and sets up the SequelHook.]]
219** Related to the above, after the Slayer wrecked the one thing that was staving off Earth's energy crisis, the game ends with [[spoiler:Hayden planning to use the Crucible to continue his exploitation of Hell's resources. Considering that [[VideoGame/DoomEternal the sequel]] will be set in HellOnEarth, he sure succeeded in averting another energy crisis... by getting most of mankind wiped out by the LegionsOfHell.]]
220* 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.
221* {{Gorn}}: This game does not shy away from gruesome and bloody violence as used by both the Doomguy and the forces of Hell.
222* GratuitousLatin: The [[FinalBoss Spider Mastermind]] is also named the "Aranea Imperatrix", although that acutally translates to "Spider ''Empress''".
223* 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. [[EvilSoundsDeep Its voice]] can occasionally be heard when you go trekking through Hell, urging the rest of demonkind to stop you.
224* 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.
225* GuideDangIt:
226** Only a handful of secrets, collectibles and upgrade sources like Argent Cells or Elite Guards can be found in areas you visit automatically as part of the campaign. The vast majority is hidden in out-of-the-way corners of the game world that're often tough to spot, with some having prerequisites to even become accessible in the first place (the Classic Maps with their fiendishly well-hidden switches are a prime example for the latter). It's highly unlikely for first-time players to find more than half of the available secrets and upgrades without consulting a detailed guide.
227** While most level challenges aren't difficult to set up and complete, a few might require a push in the right direction, usually because they can only be done at a specific point in the level without that fact being readily apparent.
228* GunNut: At one point, Samuel Hayden sarcastically notes that Doomguy seems to have an affinity for guns.
229* 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.
230* 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.
231* 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. In addition, a death on Ultra-Nightmare mode is punctuated with the words "The torment has ended."
232* HeadCrushing: Several [[CruelAndUnusualDeath Glory Kills]] involve smashing an unlucky demon's head into paste, either from above [[GoombaStomp with his boot]] or the demon's head being between the Doom Slayer's fist and a hard surface.
233* HeavilyArmoredMook: Mancubi and Pinkies now have armor covering their bodies, protecting them from any hits on those parts. Pinky armor can be destroyed with enough firepower, but its generally more cost-effective to just shoot them in their vulnerable backsides.
234* HeelFaceTurn:
235** [[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.]]
236* HellIsThatNoise: Literally. You can usually tell there are demons nearby from the incessant hiss/moan/growl noise the Possessed emit.
237** 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 its 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.
238* HellOnEarth: Demons are invading from Hell into our universe through a rip in reality on Mars (although it isn't until ''Eternal'' that they actually ''go'' to Earth).
239* 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.
240* 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.
241* 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.
242* {{Homage}}: If the Doomguy dies from falling into the molten metal in the foundry, he gives a weak thumbs-up Ă  la [[spoiler:the T-800]] from Film/Terminator2JudgmentDay.
243* HorrifyingTheHorror: Later in the game, it's revealed that the demons are ''absolutely terrified'' of Doomguy, seeing him as an unstoppable fighting machine who they struggled to seal away.
244* 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.
245* 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). In addition to eight "standard" guns[[note]]pistol, combat shotgun, super shotgun, heavy rifle, chaingun, plasma rifle, gauss cannon, rocket launcher[[/note]], there's two mods for each gun (except the pistol and super shotgun) which can be swapped on the fly, as well as the chainsaw and BFG which are not located on the "main" weapon selection wheel. As well as frag grenades, holograms, siphon grenades. Meaning that Doomguy has '''nineteen''' discrete weapons systems at his fingertips.
246* ICannotSelfTerminate: VEGA says this [[spoiler:when you're going towards his core to shut him down. Therefore, he helps you with the process]].
247* 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.
248** "[[EasyModeMockery I'm Too Young To Die]]" (Easy mode)
249--->Select this difficulty if you prefer a more relaxed gaming experience. When entering combat you will have a high chance of success. While not without its challenges, this difficulty should help keep your blood pressure in check.
250** "Hurt Me Plenty" (Normal mode)
251--->Choose this difficulty if you want to play the game without any adjustments. You will need a balance of focus, aggression, and fearlessness to ensure your survival.
252** "[[Literature/AClockworkOrange Ultra-Violence]]" (Hard mode)
253--->For players who want a challenge. This will test your awareness and reflexes, with your path to success determined by choosing the right tool for the job. There are fewer tutorials.
254** "[[HarderThanHard Nightmare]]" (Very Hard mode)
255--->For the expert player. Combat is a knife edge. One mistake can be the difference between living and a gruesome death. There are no tutorials. '''You will be unable to adjust difficulty settings after starting the campaign on Nightmare. Are you sure you want to continue?'''
256** "Ultra-Nightmare" (Very Hard mode, but you have to start the game all over again when you die)
257--->This is Nightmare with one major adjustment - if you die your campaign is OVER and a death marker will be left behind as a reminder of how far you progressed. You can save your campaign upon completing a mission and dying or falling in a Rune Trial will not affect your progress. '''''Just to confirm, are you willing to put yourself through this?'''''
258* InterfaceScrew:
259** 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.
260** Powerful impacts in close proximity to the Doom Slayer, like a Hell Knight's pounce attack landing nearby, shake the whole screen including things like health bars, ammo count, and the crosshairs. [[JustifiedTrope Justified]] in that they're part of the in-universe HUD in the Praetor Armor's helmet, as seen when Doomguy puts it on near the beginning.
261* ItsAllUpstairsFromHere: The Argent Tower level, where you have to ascend said tower in pursuit of Olivia Pierce.
262* 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.
263* JawBreaker: Just one of the many Glory Kills you can perform, usually triggered by attacking the target from behind. One of the earlier levels requires you to kill four imps this way to complete the Chiropractor challenge.
264* 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.
265* KillEnemiesToOpen: The demonic presence has a lot of areas placed under lockdown, so they need to be cleared of demons in order to advance.
266* 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.
267* 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 stolen it from you. Doubles as a CoolSword.]]
268* 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.
269* LeadTheTarget: The few guns that aren't {{Hitscan}}, like the Plasma Rifle, the Combat Shotgun's GrenadeLauncher upgrade or the Rocket Launcher, require you to do this against moving targets. However, and more importantly, enemies are very adept at this, too. Simply staying in motion during battles is not enough to escape incoming enemy fire, you must keep changing directions continuously in order to survive.
270* 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]].
271** Doomguy has a [[RunningGag bad habit]] of smashing screens, radios, and other communications devices any time [[MrExposition Hayden]] tries to [[InfoDump dump a load of exposition on him]], which is basically one hundred percent an intentional reflection of the player fanbase with no patience for the plot and who're [[JustHereForGodzilla only here for the demon-blasting]].
272** The legions of Hell are terrified of the Doom Slayer in part for his ability to [[RunDontWalk run endlessly without tiring]], [[TheNeedless go without food or sleep]], and [[EssenceDrop draw strength and vitality from those he has killed]] -- in other words, he's an FPS protagonist.
273* LethalLavaLand: The Foundry level. Well, it's actually molten metal instead of lava that's flowing all over the place, but close enough.
274* LevelEditor: The game lets you create [=SnapMaps=] that can be shared online.
275* LifeDrain: The Siphon Grenade steals health from enemies in the blast radius and gives it back to the Doomguy.
276* 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.
277* LoreCodex: The codex is a series of data entries that contain information about enemy monsters encountered during the campaign, in addition to weapons and modifications which have been acquired.
278* LudicrousGibs: A lot of the enemies can be easily gibbed. Enjoy a ''HELL'' of a bloodbath!
279[[/folder]]
280
281[[folder:M-Z]]
282* MacGuffin: The Crucible.
283* MacrossMissileMassacre:
284** 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.
285*** With the Rich get Richer rune, full armor, and fully upgraded mod, the heavy AR can launch infinite missiles without pausing or reloading.
286** The Rocket Launcher has the Lock-on Burst mod, which fires three rockets at the locked target.
287** Revenants can fire a missile barrage with their MLRB implants, rather than the two-at-a-time from the original ''Doom'' games.
288** The Cyberdemon now has a MLRB system implanted in its back. The grafted launcher in its left arm can launch a hefty salvo as well, one at a time.
289* MadeOfPlasticine: What any demon becomes should the Doom Slayer get his hands on them while they're wounded and momentarily recuperating. Exaggerated when the Doom Slayer is enraged by a Berserk powerup, where they don't even need to be heavily wounded to be ripped and torn even more brutally.
290* 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.
291* MagneticWeapons: The Gauss cannon uses magnets to fire projectiles. (Though the game refers to it as a Guass cannon, its appearance is that of a rail gun.)
292* MarathonLevel: Lazarus Labs. So long that the level is actually split into two parts.
293* 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.
294* MeaningfulName: "Argent" is the French word for "money," meaning that in the future, ''everything'' will literally be powered by greed.
295* 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.
296* ModelMuseum: Hunting down figurines throughout the campaign lets you view models for a variety of monsters, weapons and characters.
297* 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.]]]]
298* MonsterThreatExpiration: 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.
299* MookHorrorShow: Downplayed with the Slayer's Testament; historical records found in Hell which recount the Doomslayer's unstoppable slaughter of Hell's demons from their own perspective. To humans it's a victory against the dark, to the demons it was one of the most terrifying disasters in history.
300** 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.
301* MoreDakka: The further you progress through the game, the more bullets you can unleash in ever-decreasing time spans. The evolutionary chain roughly goes like this: [[EmergencyWeapon pistol]] --> [[ShotgunsAreJustBetter shotgun]] --> [[BoringButPractical Heavy Assault Rifle]] --> MacrossMissileMassacre upgrade for said assault rifle --> [[GatlingGood Heavy Gatling Gun]] --> gatling mod that turns the weapon into a ''triple gatling'' turret --> [[InfinityPlusOneSword BFG 9000]].
302* MultiversalConqueror: The LegionsOfHell do this, and each world that falls to them gets added to Hell's landscape.
303* MusicalNod: Much of the music in the game is heavily inspired by "At Doom's Gate", the [[Level1MusicRepresents well-known]] music of the first map of ''VideoGame/{{Doom}}'', but with that signature Mick Gordon heaviness.
304* MythologyGag: ''Many''.
305** 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.
306** The Martian Hero Stele in Doom 3 which depicts an unknown figure wielding the Soul Cube against the demons [[https://doomwiki.org/w/images/c/ce/Doom2016_SoulCube_ArgentDNur.jpg can be found in the final level]]. [[spoiler: This raises questions about the connection between both games, and the issue of an "Ancient Martian Civilization" gets brought up again in [[VideoGame/DoomEternal the sequel]] when the Slayer visits the Lost City of Hebeth during the Mars Core mission.]]
307** 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.
308** 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.
309** 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.
310** 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.
311** The BFG-9000's visual design heavily resembles its appearance in the [[Film/{{Doom}} Doom film]], and fires up similarly. You also need to grab body parts to access areas, just as Sarge had to do in the flick - and you have to use someone's arm to get into the BFG room, just as Sarge.
312** 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.]]
313** 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.
314** 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.
315** The achievement obtained by upgrading and fully mastering all your weapons is called simply IDKFA, the original doom all weapons/ammo cheat code.
316** 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]].
317** 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.
318** 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.
319** The very last scene of the credits, which shows the Doom Slayer getting swarmed by Imps and Possessed, is a shot for shot remake of the original game's box art. Though it's taken a step farther and has the Doom Slayer yanking the Imp grabbing his arm into the air with him and instagibbing it with his shotgun.
320** The infamous "Rip and tear" line from [[{{Comicbook/Doom}} the Doom comic]] is used, albeit in a far more ominous and threatening manner. The "GAME COMPLETED" screen may also be a reference to the comic's final panel; both feature the Doomguy standing over the corpse of his slain opponent, holding the BFG.
321** According to gameplay designer [[https://twitter.com/JunctionEight/status/855603617927237635 Jason O'Connell]], the final combat arena of Kadingir Sanctum was deliberately modeled to resemble the starting area of ''VideoGame/Doom64'''s Map 17, "Watch Your Step". In addition, Kadingir Sanctum is alternatively known as "Blood Keep", which is Map 16 of the aforementioned game. [[spoiler: This is one of the biggest indicators that both the classic and new series are connected, later expanded upon in ''VideoGame/DoomEternal'' and retroactively alluded to in the re-release of ''Doom 64''.]]
322** The 'Centered Weapons' option moves all of your weapons in first-person to the bottom center of your screen, mimicking the quirky-by-today's-standards weapon animations of the classic ''Doom'' games. The Shotgun in this mode also gets a unique backhand pumping animation that mimics the same from ''Doom'' and ''Doom II''.
323* 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]]". The UAC christens him the "DOOM Marine".
324* NeckSnap: Doomguy does this on several Glory Kills. The game doesn't shy away from providing some [[SickeningCrunch appropiate sound effects]].
325* NewWeaponTargetRange: Right after obtaining the {{BFG}}, there's a room full of various Possessed and other demons. Since a new weapon is always selected by default upon pickup, the player will be wielding the BFG and likely immediately fire it upon seeing the sheer scale of the demon-possessed hordes. It takes only one shot to turn everything in the room into LudicrousGibs and immediately gets the power of the gun across in less than three gorefilled seconds.
326* 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, Cyber-Mancubi, and Cyberdemon to turn them into living weapons.
327* 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.
328* 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.
329* 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.
330* NostalgiaLevel: A few examples.
331** Every level has an area using the textures and maps of the original two games, which unlocks said levels in full from the menu.
332** The [[spoiler:Icon of Sin]] makes a reappearance, still dead as a doornail.
333** One of the levels in Hell features an adaptation of ''Dead Simple''.
334* NoticeThis: Grabbable ledges are often clearly marked with green lights.
335* 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.
336* 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.
337* OneHitKO:
338** The chainsaw now takes down anything in one hit, but it takes fuel to do it. Naturally, it doesn't work against bosses.
339** The Berserk powerup lets you kill absolutely anything[[note]]it probably doesn't work on bosses, too, but since the powerup is never found during boss battles, it doesn't matter all that much[[/note]] with a single melee attack, which arguably makes it even more powerful than the ever-popular QuadDamage.
340* 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.
341* OneHitPolykill: A lot of weapons can be upgraded to either deal area damage (Combat Shotgun, Plasma Rifle, Assault Rifle), overpenetrate targets (Pistol, Super Shotgun, Gatling Cannon), or both (Gauss Rifle). The Gauss Rifle reigns supreme in this department, especially its Siege Mode upgrade that's capable of clearing entire corridors packed wall-to-wall with enemies in one shot, two at most, as long as most of them are lined up right. These weapons often require you to perform a number of poly-kills to master the respective upgrade.
342* OneWordTitle: Just like [[RecycledTitle the original]] [[VideoGame/{{Doom}} game]].
343* OutsideTheBoxTactic: There's really no way to make the "Rich Get Richer" rune trial ''easy'', as it were, since the demons on the map are positioned so they can quickly box you in if you dash forward to try circling the arena or if you run to the center. Because of that, however, doing a quick 180 and running in the ''opposite'' direction from where you start out gives you more space to maneuver and start thinning out the enemy ranks before they can all close the distance and overwhelm you.
344* LeParkour: The Doomguy is surprisingly agile, able to grip onto ledges to find secrets and hidden powerups.
345* PassThePopcorn: Subverted. You can occasionally observe groups of demons fighting each other in the distance, but if you stay put for too long while you watch them tear each other apart, the game will spawn a bunch of enemies right on top of you.
346* PayEvilUntoEvil: The Doom Slayer mercilessly rips and tears his enemies apart in the most brutal ways imaginable as they scream in terror, leaving a mountain of corpses in his wake. However, since his enemies are ''literal'' demons from Hell, nobody ''really'' feels all that much in the way of pity for them.
347-->'''Voice:''' They are rage, brutal, without mercy. But you. You will be '''worse'''.
348* PersonOfMassDestruction: If the demon logs are any indication, the arrival of the Slayer is treated as an apocalyptic event by the combined forces of hell. No matter what they do, they simply cannot stop him.
349* 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.]]
350** On picking up the Classic Guy collectible, the Doomguy adjusts its arm and stops to give its tiny fist a brotherly bump.
351* PhotoMode: Still called "DOOM Photo Mode [Beta]" in the settings. Lets you unpause the game frame-by-frame and comes with a few lenses, though it removes the Doom Slayer from the shots.
352* PinataEnemy: As literal as it can possibly get - hit any enemy particularly good (as in, apply your chainsaw to its face) and they'll cough up a veritable torrent of ammunition, often enough to completely refill your entire stockpile for all weapons. Also, glory-killing enemies always yields some health and occasionally ammo (plus armor if you have the Armored Assault rune active) from their mutilated corpses.
353* PinballSpinoff: Courtesy of Creator/ZenStudios, there's an [[{{Bowdlerize}} everyone-ten-and-up]] way to enjoy slaying demons - a virtual pinball table where demonic foes appear as pop-up cutouts and animated figures bloodlessly shoot and bash each other.
354* PocketRocketLauncher: An alt-fire mode for the Assault Rifle is a miniature heat-seeking missile rack, that fires in bursts of six. After achieving Weapon Mastery, it launches an uninterrupted stream of them.
355* 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.
356* PoweredArmor: Doomguy's Praetor Suit, which according to the Slayer's Testaments, [[spoiler:was created/improved by a demon who betrayed Hell and sided with him]].
357* PurpleIsPowerful: The Quad-Damage powerup is purple, and causes you, your weapons and projectiles to glow purple when in effect.
358* QuadDamage: Makes its ''Doom'' debut after being a staple item in id's ''VideoGame/{{Quake}}'', and shows up in both single-player and multiplayer.
359* 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.
360* 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 cost them the unlimited energy source that could have been used to solve the energy crisis back on Earth.]]
361* {{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 a nightmare world - this game brings the series back to its roots:
362** The space marine running, gunning, ripping, and tearing his way through TheLegionsOfHell with all the guns and chainsaws you can carry makes sense, because here he isn't some nameless {{Mook}} soldier right off the boat. Instead the Doom Slayer is a badass EternalHero that's been around for eons, is able to channel Argent energy (one of the great energy sources of hell) to become stronger, is so full of rage that it makes him a twisted form of IncorruptiblePurePureness making it impossible for hell to corrupt him, was eventually empowered by the seraphim with physical power like unto a demi-god, and later gained armor that, in the lore, is nigh-indestructable. While the horror is every bit as bad as in Doom 3, it's very clear that you aren't trapped on Mars surrounded by demons; rather, the demons are trapped on Mars with ''you''.
363** Tied in with the above, this game shows you what it would take and who would be powerful enough to challenge the hordes of hell. Then it shows how terrifying it would be ''[[HorrifyingTheHorror for the demons]]'' if such a warrior were successfully smashing through their ranks without slowing down.
364** It also shows under what conditions it would take for the UAC to be knowingly complicit with the harvesting of energy from hell and how it would be allowed. The answer? Only the highest executives know what's going on, and even they only know that the energy comes from another dimension. Samuel Hayden, who reports directly to them, does know the implications but only tells them what they need to know and not the more disturbing truths. As for why people would knowingly work on a project that draws energy from hell? They're carefully selected and the project headquarters is the site of a cult, with all the workers being a part of it, and see the use of hell energy as a good thing while the more amoral people in charge ignore this because they can use these workers/cultists for experiments and the situation gets results.
365* {{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.
366* TheRemake: This 2016 game takes the name, general premise and core run 'n gun gameplay of 1993's ''VideoGame/{{Doom}}'', while also using modern graphics, gameplay elements, story telling conventions and so on. However, as revealed in ''VideoGame/DoomEternal'', [[spoiler:it's also a StealthSequel to the classic games.]]
367* ReplayMode: From the menu of your save file, you can not only replay the levels you've cleared, but also the Rune Trial minigames you unlock in them. The only condition for the latter is that you must have cleared them at least once.
368* 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.
369* 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".
370* RPGElements: ''Doom's'' biggest concession to modern FPS design is a number of skill and uprade trees used to pemanently make the Doom Slayer more powerful as the game progresses.
371* RoaringRampageOfRevenge: What the Doomguy's motivation for fighting against Hell is hinted to be. Codex entries and The Slayer's Testament imply either [[spoiler:a) he's the original Doomguy who lost his squad in ''Doom'', his Earth in ''Doom II'', and has been wandering the realms fighting Hell over the eons since the end of ''Doom 64'', including at one point the world Argent energy comes from, Argent D'nur. b) He was part of the Night Sentinels, the protectors of Argent D'nur, before they were betrayed from within and Hell absorbed the entire realm, leaving only the Slayer still alive.]] ''VideoGame/DoomEternal'' reveals that in fact ''both'' of these backstories are true.
372* RocketJump: You can get a boost for your jumps by using the Gauss Cannon's recoil to get a little more airtime.
373* 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.
374* RuleOfCool: The game runs on this entirely. Why does killing hordes of demons enable you to upgrade your guns further? Why do civilian delivery drones carry military weapon upgrades? Why do demons drop tons of ammo when you murderize them with a chainsaw, and only with a chainsaw? What are chainsaws doing on Mars in the first place?[[note]]This one gets even lampshaded by the item description itself[[/note]] Who cares?! It all makes the game more entertaining, and that's all that matters.
375* 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.
376* {{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 up to eleven.
377* 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. Usually all three.
378* 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 one hell of an impression.
379* 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.]]
380* SecondaryFire: Some weapon mods give secondary firing modes, like an explosive shot for the shotgun or mini-missiles for the heavy assault rifle.
381* 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.
382* SequelHook:
383** 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.
384*** 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.]]
385** The Doomguy [[spoiler:saves a backup of VEGA before destroying him]]. In ''Eternal'', [[spoiler:VEGA has become the AI that runs the Slayer's orbital fortress]].
386* 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.
387* ShieldBearingMook: Possessed Security have large shields that defend them from frontal attacks.
388* ShortRangeShotgun: To be expected from a game like this. The Combat Shotgun has a maximum range of about ten meters and stops dealing its full damage if the target is more than two steps away. The Super Shotgun is basically useless against anything beyond punching distance, but inside that range it ''will'' obliterate anything smaller than a Hell Knight with a single shot.
389* ShoutOut:
390** As with the original, one of the difficulty settings is "[[Literature/AClockworkOrange Ultra-Violence]]".
391** If you die by falling into a lava pit, the Doom Marine will [[Film/Terminator2JudgmentDay give a Terminator-esque thumbs up]].
392** 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''.
393** 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''.
394** Just as in VideoGame/QuakeIIIArena, picking up extra armor that surpasses your default meter will decay over time.
395** One of the multiplayer taunts is [[Series/TheFreshPrinceOfBelAir Carlton's dance.]]
396** 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]].
397** 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.
398** A door early on in the game has a [[VideoGame/{{Fallout}} Vault-Tec]] logo on it.
399** 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.
400** The demons ApocalypticLog is titled the Music/{{Slayer}}'s Music/{{Testament}}.
401** 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''.
402** The hidden ''Super Turkey Puncher 3'' arcade cabinet has a logo that's designed to resemble that of ''VideoGame/StreetFighterAlpha 3''.
403** 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]].
404** One of the Glory Kills you can inflict on the Revenant is horrifically reminiscent of a particularly gruesome bit of violence on ''Series/GameOfThrones'' involving thumbs in eyesockets, followed by the Doom Slayer snapping the demon's neck, ''then'' crushing its skull in an explosion of gore.
405** The Quad Damage powerup is taken straight from ''VideoGame/{{Quake}}''.
406** There are many [[http://thereticule.com/doom-and-half-life-lost-cousins/ visuals references]] to ''VideoGame/HalfLife1'', itself heavily inspired by the 90s ''Doom'' games.
407** The Hell Guard bosses are a subtle reference to the [[Toys/{{Bionicle}} Rahkshi]], being suits of armor controlled by a larval creature.
408* 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.]]
409* 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, but he rather violently disagrees.
410* SilentSnarker: Not only silent, but ''faceless'', too. Though he remains a HeroicMime, the Doomguy's characterization has been subtly upgraded to visually indicate what is perhaps a surprising level of cynical perceptiveness in regards to the Hellish insanity going on around him, especially in regards to [[WellIntentionedExtremist Hayden.]] When Hayden assures Doomguy over the radio that the UAC's work has been "for the betterment of mankind", Doomguy looks down at the mutilated corpse in the elevator with him, as if to say "Well, there's mankind. [[ShutUpHannibal Does he look better off to you?]]"
411* SniperPistol: The game's basic pistol can, when upgrade, function as a fairly reliable if unimpressive sniper weapon. Careful charged shots can one-shot lower level enemies at a great distance and, thanks to its unlimited ammo, chip away at the damage of tougher enemies indefinitely. It's not necessarily very quick (or even very fun) but it's a good way to clear some easy kills if you can keep your distance.
412* SortingAlgorithmOfEvil: Strangely averted in a few cases; for example, you have to slaughter several Hell Knights well before the first Pinky demon shows up (although admittedly the 2016 ''Doom'' Pinky is [[TookALevelInBadass considerably stronger]] than it was in the classic games).
413* SpiritualAntithesis: The 2016 ''Doom'' game can be thought of as the spiritual antithesis of ''VideoGame/GearsOfWar''. The two games have a lot in common aesthetically, being shooter games that attracted notoriety for allowing you to dispose of monsters in spectacularly gory ways, but beyond how they look, these two games couldn’t be more different in how they play. ''Gears'' features slow movement, no jumping, and RegeneratingHealth, all of which encourage you to TakeCover in one place in order to stay alive. ''Doom'' on the other hand, features fast movement, JumpPhysics, and non-regenerating health, which encourage you to constantly move around the battlefield to avoid enemy fire and pick up health dropped by dead enemies. Both games were also released a decade apart, with ''Gears'' establishing trends that the shooter genre would follow for the next ten years, and ''Doom'' getting attention for defiantly bucking those trends. Though for what it's worth, regardless of how the developers ''intended'' for people to play ''Gears'', [[GameplayDerailment pinballing around the map at high speed with a shotgun is how everybody actually plays it]], so in practice the two games are more similar than initially apparent.
414* StepOneEscape: The game starts with the Doom Slayer shackled on an examination table surrounded by dead bodies and an enemy shambling toward them. The Slayer/Player manages to free one hand, kill the enemy, arm themselves and kill more, find their armor in the next room, and then fight their way out of the facility. Only ''then'' does the title actually appear.
415* SuspiciousVideoGameGenerosity: If you run into a large pile of ammo, health, and armor, you can expect a boss fight to follow shortly.
416** The battle with the Hell Guards is preceded by a corridor filled to bursting with health and armor pickups.
417** 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.
418** Most of the final level is non-stop ammo resupplies, especially around the corpses of the Wraiths.
419* 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 a ''lot'' of dimensions are invaded and absorbed into Hell, and the Slayer's Testaments also make it clear he rampaged anywhere where demons could be found. 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. The ambiguity is cleared up drastically in the sequel, which confirms that the Slayer is indeed the very same Doomguy that fans know and love from the original series.]]
420* StealthSequel: It's implied that the Doomguy in this game [[spoiler:is actually the very same one from the original two ''Doom'' games. The next game outright confirms it]].
421* 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).
422* TranquilFury: How else can you describe a man who carves through the forces of hell without uttering a word.
423* 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.
424* 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.
425* 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.]]
426* ToHellAndBack: You will travel to and from Hell a total of three times over the course of the game. The first time occurs when Doom Slayer gets caught in a nexus he is racing to stop but the two times after that are deliberate jaunts to reclaim an artifact and finally seal the source of Argent energy once and for all.
427* TookALevelInBadass: A number of returning enemies from the past games are ''significantly'' faster and more aggressive than before, and have new attacks and capabilities.
428** 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.
429** 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.
430** 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.
431** 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.
432** 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.
433** 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.
434** 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]].
435** 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!
436** 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.
437** 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.
438** [[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.]]
439* 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.
440* TurnsRed: Inverted [[spoiler:with the Spider Mastermind, which becomes increasingly bruised and crippled after a considerable number of hits are landed on it. It is eventually reduced to pathetically cowering from you, spewing lasers at random and trying to shield itself with its limbs.]]
441* UnexpectedGameplayChange: Rune Trials are still mostly about killing demons, but they're completely detached from your current campaign task, they happen in another dimension, impose very specific restrictions on you, can be repeated indefinitely despite most failures resulting in your death, and a few even completely lack enemies or anything else to shoot.
442* TheUnfought: [[spoiler:Samuel Hayden]], knowing full well they'll probably be murdered in a fair fight, instead [[spoiler:cooperates with Doomguy long enough until they can find a way to temporarily entrap him long enough to escape.]] Notably, they do this ''because'' they know they won't stand a chance of winning against Doomguy.
443-->[[spoiler:'''Samuel Hayden:''']] I am not the villain in this story. I do what I do because there is no choice.
444* UnfriendlyFire: Aside from the classic "trick enemies into shooting each other", glory-killing a possessed engineer results in the Doom Slayer kicking the guy across the room where he'll explode upon impact, potentially blowing up a fair number of his fellow demons in the process.
445* {{Unobtainium}}: The [[AppliedPhlebotinum Argent energy]] used to power everything drives a portion of the story, [[spoiler:being from Hell itself and all.]] Thanks to all the problems it causes, when told to disable the Argent processor in the mission "Argent Facility", Doom Slayer instead simply ''destroys'' all the filters, cutting humanity off from the substance entirely.
446* 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.
447* 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.
448--> '''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''.
449* VariableMix: The game's soundtrack transitions between ambient and combat music. Events such as glory kills seem to have an independent measure that's merged with music playback, and sometimes a changing situation also adjusts the intensity of the combat music.
450* VideoGameCrueltyPotential: Like ''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.
451* VirtualSidekick: VEGA is an AI that was saved by the Doomguy who later on became his fountain of exposition.
452* 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.
453* 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.
454* WellIntentionedExtremist:
455** Both [[TheQuisling Olivia Pierce]] and [[{{Cyborg}} Samuel Hayden]], the former working with Hell to bring about a new world for mankind and the latter wanting to utilize Hell for [[{{Unobtainium}} its resources]] to usher in a better world for mankind as well. [[spoiler:Although in Olivia's case it [[TheCorruption eventually degenerates]] into "Obtain God-like power".]]
456** 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. However, according to Samuel, the discovery and collection of argent energy in Hell saved human civilization from being destroyed by an energy crisis; a crisis the overzealous Doomguy may have restarted after destroying the systems that were processing the hell-energy and transporting it to Earth.
457* WhamShot: Seeing Samuel Hayden for the first time. You've just paved your way through a facility on Mars, wiping out Imps and Possessed until you get your first upgrade next to a computer. Samuel appears on the screen, and it turns out that he isn't just some executive in a suit, but a ''towering robotic {{Cyborg}}''.
458* 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. [[spoiler:This actually ends up motivating Samuel's betrayal in the cliffhanger ending, pointing out that the Doomguy would rather destroy Hell than prevent humanity's Argent-dependent society from collapsing. But if ''VideoGame/DoomEternal'' is to be believed, he eventually realized that Doomguy was right.]]
459* 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.
460* 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. It's undoubtedly a CrapsackWorld, to be sure... but it's one that's still '''totally fucking awesome.'''
461* 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.
