History VideoGame / Doom3

** ''Doom 3 Redux'' improves on the game's visuals, restores some cut features from original game, remasters the game's audio logs, and adds lots of modern tweaks thanks to a custom build of Sikkmod that allows for more advanced options while maintaining the original ''Doom 3'' gameplay. Sadly it's only available for the base game and not ''Resurrection of Evil''.

** Classic Doom for Doom 3 does pretty what it says on the tin, which is recreate the first episode of Ultimate Doom, ''Knee-Deep in The Dead'', in Doom 3's engine. Also WhatCouldHaveBeen, as Episodes 2 and 3 were planned, but scrapped during development. On the plus side, it has some awesome remixes of the first episode's soundtrack.

* MissionControl: Sergeant Kelly serves this role in the main game for the first half.

* AdaptationExpansion: The novelizations either benefited or suffered from this depending on your personal taste. They include a lot more information about the UAC, character backstories, and the state of Earth, but almost the entire first book can be skipped and not miss any parts of the game.

* {{Jerkass}}: Sgt. Kelly.

* MissionControl: Sergeant Kelly serves this role.
** Doctor McNeil fills this role in ''Resurrection of Evil''.

* UpdatedRerelease: The ''BFG Edition'' features remastered versions of ''Doom 3'', the ''Resurrection of Evil'' expansion pack, and a new set of levels cut from the original game in the form of ''The Lost Mission'', all with improved lighting and rendering, support for 3D TV displays, native ultrawide support (the original game needed a fan-made patch for ultrawide resolutions), a new (though optional) checkpoint system, re-tooled gameplay elements (e.g. less enemies to battle, shoulder-mounted flashlight, more plentiful ammo), and achievement/trophy support. This also bundles the HD ports of ''The Ultimate Doom'' and ''Doom II: Hell on Earth'', which also gives PC players the ability to play the previously console-exclusive ''No Rest for the Living'' episode for ''Doom II''.

* AntiClimax: When you first teleport, the game presents Hell as a twisted, Hieronymus Bosch-ian nightmare. Then you finally get to Hell, and it's basically a LethalLavaLand.

* ExplodingBarrels: Has a variant on these with the yellow toxic barrels. Once you shoot them, they simmer for a couple of seconds before exploding (though they will explode automatically if caught in the splash of another explosive).

** Fast zombies shamble almost at a job. Only one is ever found in the base game.

** Fat zombies, who can absorb slightly more damage than basic zombies.
** Flaming zombies, also known as "Bernie".
** Fast zombies, who shamble much faster than basic zombies.
** Chainsaw zombies, which are ExactlyWhatItSaysOnTheTin.
** Commandos. They either carry a chaingun or have a [[CombatTentacles tentacle]] as their right arm.

* NoSidepathsNoExplorationNoFreedom: Compared to the abstract layouts of the classic games, the ''Doom 3'' levels are very linear.

* StupidEvil: Dr. Malcolm Betruger, who apparently has no actual motive for attempting to transform Earth into Hell and its people into screaming demon-fodder. It is implied, however, that he has been possessed or is in some way controlled by the demons. The novels indicate he was an ordinary scientist who was subject to MoreThanMindControl; alternatively ''The Lost Mission'' campaign indicates he always had an obsession with the occult and was offered ultimate power by the demons in exchange for Earth. ''Resurrection of Evil'' shows that [[spoiler:the demons turned Betruger into a powerful demon in exchange for his aid, so that was probably part of his motivation.]]

* SequelNumberSnarl: [[SubvertedTrope Subverted]] as this game was a reboot (and later kicked out of continuity entirely), but this game is technically the 4th installment after VideoGame/Doom64 (5th if you count VideoGame/FinalDoom as a standalone game).

''Doom 3'' is a 2004 FirstPersonShooter in the ''Franchise/{{Doom}}'' franchise, developed by Creator/IdSoftware and released for both the PC and Xbox. Despite its name, it's not a sequel to the original ''VideoGame/{{Doom}}'' games, as much as a reboot. It has a darker tone than the rest of the series, with aspects of SurvivalHorror.

** The overall tone is far more grim, serious and frightening; while other ''Doom'' games have never shied away from snarky quips, dark comedy and goofy over-the-top violence, ''3'' plays the scenario primarily for horror, with a heavy emphasis on pitch-black environments, scary sequences, and a plot that's taken dead seriously.
** Many of the returning monsters have been heavily redesigned, most notably the Cacodemon, Lost Soul and Pinky, which are practically unrecognizable. The only redesign that stuck in future installments was the Hell Knight, presumably because its original design was merely a PaletteSwap of the Baron of Hell.
** This is the only game in the series in which guns have finite clips that need to be reloaded; in all other games, the player can fire continuously until they're completely out of ammo.
** ''Doom 3'' is the only Doom game to lack true monster infighting until Eternal, as only a small handful of the more powerful monsters can deliberately attack and kill a small handful of the weaker ones, who never fight back.

* BroadStrokes: Official descriptions for the spin-off ''Doom RPG'' imply this game is a prequel to the original ''Doom'' games, and that Doomguy in ''Doom'' and ''Doom II'', and the Marine in ''Doom 3'' are both the same character. However, ''Doom 3'' takes place in 2145, while the original ''Doom'' took place in 2022, one-hundred-twenty-two years apart. The Marine also looks considerably different from Doomguy, and many of the visuals and storytelling elements don't mesh between games.

* DataPad: The standard issue [=PDAs=] of UAC personnel. Their design is more or less like a modern day tablet, but thicker and with a slight curve at the bottom separating the screen from what looks like an analog pad; there's also a port at the top to insert video disks. They serve the role of mobile work stations, e-mail and video playback platforms, audio recorders and electronic keys with specific clearances. They can also download the data from other [=PDAs=], including clearance status, and indeed in most LockAndKeyPuzzle sections your task is to find the PDA of one of the people with clearance to the area you need to go to (which is always helpfully listed in the interactive panel beside the LockedDoor when you try to unlock it).

* {{Deconstruction}}: The game goes at lengths to show just how ''terrifying'' it would be being a lone marine, trapped on Mars, with monsters teleporting in from Hell (literally).

** Notably, ''VideoGame/DoomEternal'' excluded this game in its massive CanonWelding of the ''Doom'' franchise (which included the first two games, ''VideoGame/Doom64'', and the 2016 game).

An ExpansionPack called ''Resurrection of Evil'' was released in 2005, and takes place two years after the original story. In 2012, id Software released the ''[[UpdatedRerelease BFG Edition]]'', which includes a remastered and slightly retooled version of the original ''Doom 3'' game (with an armor-mounted flashlight replacing the original's controversial flashlight system, and more ammo), ''Resurrection of Evil'', an all-new mini-campaign called ''The Lost Mission'' (consisting mostly of cut content), [[EmbeddedPrecursor plus]] ''The Ultimate Doom'' and ''VideoGame/DoomII'', as well as the ''No Rest for the Living'' expansion that was developed for ''Doom II''[='=]s UsefulNotes/XboxLiveArcade release, making for a very packed ''Doom'' experience. Another standalone re-release of the ''BFG Edition'', simply titled ''Doom 3'', was released in 2019 along with the updated ports of ''Doom'' and ''Doom II'' for the 8th generation of consoles and PC.

* DiegeticInterface: When the player is wielding a machinegun, plasma gun, chaingun, or BFG-9000, the ammo counter disappears from the HUD and is replaced by a number displayed on the weapon itself. ''BFG Edition'' changed this so the HUD ammo counter always shows regardless.

* DummiedOut: A variant of the Imp that moves on all fours is fully coded into the game, but doesn't appear anywhere. Its rig was re-used for the Vulgar in ''Resurrection of Evil'' with slower movement speed.

Just like in the original game, you're a [[NoNameGiven nameless]], [[HeroicMime silent]], badass SpaceMarine, who has just been assigned to the Union Aerospace Corporation's base on UsefulNotes/{{Mars}}. Upon arriving and reporting to your sergeant, you are given your first task: find a scientist who has gone missing in the old communications facility. At first glance, the place and assignment seem [[NothingExcitingEverHappensHere as dull as dirt]], but as you speak to other marines and workers during your search, the creepier things start to seem. Many employees seem frightened and paranoid, and then there's the fact that the whole reason you were assigned here in the first place was to replace another Marine who died during an operation. You also overhear some rather suspicious conversations held by a high-ranking UAC lawyer and his lackey, and shadiest of all, the creepy and mysterious director of research [[BigBad Dr. Malcolm Betruger]], who promises that "amazing things will happen". By the time you find the missing scientist, things are already creepy enough, but then Hell literally breaks loose, and you find yourself as one of the few people left alive in a base rapidly being overrun with grotesque monsters, reanimated and murderous former humans, and otherwordly, demonic imagery. It's up to you find and stop the source of the invasion, locate and aid any fellow survivors, and fight to stay alive.

* NighInvulnerable: The Engineer Marine becomes this through the Artifact once it absorbs the power of the Invulnerability Hunter.
