'''''Doom 3'''''{{efn|Stylized as '''''DOOM³'''''}} is a 2004 [[first-person shooter]] game developed by [[id Software]] and published by [[Activision]]. It was originally released for [[Windows]] on August 3, 2004, before being adapted for [[Linux]] later that year, and [[Video game port|ported]] by [[Aspyr Media]] for [[Mac OS X]] in 2005. [[Vicarious Visions]] ported the game to the [[Xbox (console)|Xbox]], releasing it worldwide on April 4, 2005.

''Doom 3'' is set on [[Mars]] in 2145, where a military-industrial [[Conglomerate (company)|conglomerate]] has set up a scientific [[research facility]] into fields such as teleportation, biological research, and advanced weapons design. The teleportation experiments open a gateway to Hell conducted by Doctor Betruger, resulting in a catastrophic invasion of the Mars base by demons. The player controls a [[space marine]] who fights through the base to stop the demons attacking Mars and reaching Earth.

''Doom 3'' is the first reboot of the ''[[Doom (franchise)|Doom]]'' series, [[Retroactive continuity|ignoring the events of]] the previous games. ''Doom 3'' utilizes the [[id Tech 4]] game engine, which has since been licensed out to other developers, and later released under the [[GNU General Public License|GNU General Public License v3.0 or later]] in November 2011.

''Doom 3'' was a critical and commercial success; with more than 3.5 million copies of the game sold, it was the most successful game by developer id Software up to that date. Critics praised the game's graphics, presentation, and atmosphere, although reviewers were divided by how close the gameplay was to that of the original ''[[Doom (1993 video game)|Doom]]'', focusing primarily on simply fighting through large numbers of enemy characters. The game was followed by ''[[Doom 3: Resurrection of Evil|Resurrection of Evil]]'', an [[expansion pack]] developed by [[Nerve Software]], in April 2005. A series of novelizations of ''Doom 3'', written by [[Matthew J. Costello]], debuted in February 2008. An expanded and remastered edition, '''''Doom 3: BFG Edition''''', was released in the fourth quarter of 2012. It has been ported to various platforms, including some which enable portable and [[virtual reality]] gameplay.

==Gameplay==
===Single player===
''Doom 3'' is a story-driven action game played from a [[First-person narrative|first-person]] perspective with occasional [[cutscene]]s in a [[Third-person (video games)|third-person perspective]]. As with previous ''Doom'' games, the main objective is to successfully pass through its levels, defeating a variety of enemy characters intent on killing the [[player character|player's character]]. ''Doom 3''{{'}}s more story-centered approach, however, means that the player often encounters friendly [[non-player character]]s, who provide key plot information, objectives and inventory items. The game incorporates ten weapons for the players use to survive, including conventional firearms such as a submachine gun, shotgun and grenades, experimental plasma weaponry, and the powerful [[BFG (weapon)|BFG 9000]] and chainsaw weapons of the ''Doom'' franchise.<ref name="DM3Weapons"/> Enemies come in multiple forms and with different abilities and tactics, but fall into two broad categories of either zombies or demons. Zombies are humans possessed by demonic forces, who attack the player's character using their hands and melee weapons or a variety of firearms, while demons are creatures from Hell, most of which attack using claws and spines, or by summoning plasma-based fireballs.<ref name="DM3Enemies"/> The corpses of demons are reduced to ashes after death, leaving no trace of their body behind.

[[Image:Reverent (Doom).jpg|left|thumb|The player fighting a Revenant in ''Doom 3''. The majority of the game takes place within the futuristic base.]]

The game's levels are semi-linear in nature and incorporate several horror elements, the most prominent of which is darkness.<ref name="PCGUK"/> This design choice is not only intended to foster feelings of apprehension and fear within the player, but also to create a more threatening game environment in which the player is less likely to see attacking enemies.<ref name="PCGUK"/> This aspect is further enhanced by the fact that the player must choose between holding a weapon and holding the flashlight (until the BFG editions released in 2012 made the "duct tape mod" a standard feature), forcing the player to choose between being able to see or having a readied weapon upon entering a room, which consequently leads to a more deliberate pace for the player.<ref name="PCGUK"/> In addition, the levels are regularly strewn with corpses, chopped body parts and blood, sometimes used in conjunction with the game's lighting to disorient the player.<ref name="PCGUK"/>

Frequent radio transmissions through the player's communications device also add to the atmosphere, by broadcasting certain sounds and messages from non-player characters meant to unsettle the player. Early in the game, during and directly after the event that plunges the base into chaos, the player often hears the sounds of fighting, screaming and dying through their radio transmitter. The ambient sound is extended to the base itself through such things as hissing pipes, footsteps, and occasional jarringly loud noises from machinery or other sources. Often ambient sounds can be heard that resemble deep breathing, unexplained voices and demonic taunting from the game's antagonists.<ref name="Planet Overview"/>

Early in the game, the player is provided with a [[personal data assistant]] (PDA). PDAs contain security clearance levels, allowing the player to access certain areas that are otherwise locked and off-limits. Additionally, the PDA can be used to read e-mails and play audio logs or video discs that the player's character acquires during the game. Whenever the player picks up any of the other PDAs found throughout the game, its contents are automatically downloaded to the player's own device. Other PDAs often contain e-mails and audio logs for other characters, which can provide useful information such as storage or door key codes, as well as significant plot details.<ref name="DM3Items"/>

===Multiplayer===
''Doom 3'' was released with a four-player multiplayer element, featuring four game modes. However, the game's community created a modification to boost this to eight or sixteen players.<ref name="gamespy"/><ref name="IGNPC"/><ref name=gamespot/> The ''Resurrection of Evil'' expansion would later officially increase the player limit to eight. The four game modes are all [[Deathmatch (video games)|deathmatch]]es. The standard deathmatch game mode involves each player moving around a level, collecting weaponry and killing the other players, with the player with the highest kills when the time runs out winning. A team variation of this involves the same principle. The third game mode is "last man standing", in which each player has a limited amount of [[respawn]]s, with players losing a life when they are killed. Eventually, all but one player will be eliminated from the game, leaving the survivor as the winner. The final game mode is "tournament", in which two players fight each other while the other players watch as spectators. The victor of the battle remains in the arena, facing each other player one at a time until the winner of previous rounds is defeated. The loser then moves to the spectators and the new winner remains to fight the next player.<ref name="MP"/> The Xbox version of ''Doom 3'' also incorporates an additional two-player co-operative mode for the main single-player game.

As of April 15, 2010, the Xbox Live service was shut down, thus online multiplayer for the original Xbox game is no longer available.

==Synopsis==
===Setting===
''Doom 3'' is set on the planet Mars in the year 2145. According to the game's backstory, the Union Aerospace Corporation (UAC) has grown to become the largest corporate entity in existence with near-unlimited funds and has set up a research facility on Mars. At this base, the UAC are able to conduct research into several scientific areas, including advanced weapons development, biological research, space exploration and teleportation, outside of legal and moral boundaries.<ref name="MarsCity"/> As the player progresses through the game, they learn that the employees on the base are unsettled due to a large number of incidents involving hearing voices, unexplained sightings and increasing cases of paranoia and insanity, often leading to fatal accidents with the facility's machinery. Rumors regarding the nature of experiments in the UAC's Delta Labs division are especially prevalent among the base's employees.

Much of ''Doom 3''{{'}}s story and dialogue were written by author [[Matthew J. Costello]].<ref name="Planet Overview"/>

===Characters===
There are five main characters in ''Doom 3''. The player assumes the role of an [[Doomguy|anonymous Space Marine corporal]] who has just arrived on the UAC's Mars base. The player's [[non-commissioned officer]] in-charge is Master Sergeant Thomas Kelly (voiced by [[Neil Ross]]<ref name="credits"/>) who gives the player objectives and advice over the player's radio for the first half of the game. The antagonist in the story is Dr. Malcolm Betruger ([[Philip L. Clarke]]<ref name="credits"/>), the head scientist of the UAC's enigmatic Delta Labs division, who is revealed to be working in collaboration with the forces of [[Hell]] to cause the subjugation of [[humans|humanity]], and his demonic voice frequently taunts the player as the game progresses. The final two principal characters are Elliott Swann ([[Charles Dennis]]<ref name="credits"/>), a representative of the UAC's [[board of directors]], and Jack Campbell ([[Andy Chanley]]<ref name="credits"/>), a space marine who acts as Swann's enforcer and is armed with a [[BFG 9000]]. Swann is sent to Mars to check up on Betruger's research and investigate the rising number of accidents on the base after a request for assistance from a whistleblower. Swann is almost always accompanied by Campbell, and the two are often shown in the game to be a few steps ahead of the player but cannot be reached and directly communicated with until late in the game.<ref name="Planet Overview"/> The game also incorporates a large host of minor characters who add details to the story or assist the player in certain segments. The player encounters multiple scientists involved in the various research and development programs and archaeological digs through the UAC base, as well as fellow marines and security guards. Civilian employees engaged in bureaucratic work and maintenance workers are also seen.

===Plot===
UAC board member Elliott Swann, his bodyguard Jack Campbell, and a recently transferred Marine arrive at Mars City, the main access to the UAC's Mars base. Sent to investigate multiple incidents involving the Delta Complex, Swann has a tense meeting with facility director Dr. Malcolm Betruger while the Marine reports to Master Sergeant Thomas Kelly for orders.<ref name="DrBetruger"/> Kelly orders the Marine to find a scientist from the Delta Labs who has gone missing.<ref name="TKelly"/> The marine finds the scientist in a decommissioned communications facility, where he is frantically trying to send a warning to the UAC on Earth about Betruger's teleportation experiments.<ref name="JIshii"/> However, as he tries to explain the situation to the marine, another teleportation test takes place but loses containment, at which point the entire Mars base is swept with a shockwave. The forces of Hell invade through the teleporter's portal and transform most of the base's personnel into zombies.

[[Image:Doom3storyboard.jpg|thumb|right|Much of ''Doom 3'', such as this section in the Delta Labs, was planned using storyboards.]]

Now forced to fend off attacks from zombified base personnel and demons from Hell, the Marine returns to Mars City, where Kelly gives him orders to link up with another squad of marines and get a transmission card containing a distress call to the main communications facility to call for reinforcements. As the Marine progresses through the base, he learns that Swann and Campbell have survived and are also en route to the communications facility to prevent any messages being sent in order to contain the situation on Mars. The marine squad is ambushed by demons and slaughtered in the EnPro Plant, and although the Marine recovers the transmission card, he is too late to prevent the bulk of equipment at the communications facility being destroyed by Campbell.<ref name="EnPro"/> However, Kelly directs the Marine to a backup system, where the Marine is given the choice of whether to obey Kelly's orders to send for reinforcements, or accept Swann's argument to keep Mars isolated until the nature of the invasion is understood, so as not to endanger Earth.<ref name="BackComm"/><ref name="ESwann"/> The Marine is told to go to the Delta Labs by Kelly or Swann, depending on whether the transmission is sent or not.

On the way to the Delta Labs, the Marine is contacted by Betruger, who is now shown to be working in cooperation with Hell in order to invade Earth. If the Marine did not send the distress call to Earth, Betruger does so himself, hoping to use the ships bringing reinforcements to transport the demons to Earth.<ref name="PumpStation"/> Betruger then unsuccessfully attempts to kill the Marine using the toxic gases in the base's recycling facilities. Upon arriving at the Delta Labs, the Marine learns of the details behind the teleportation experiments, expeditions into Hell to retrieve specimens and Betruger's increasing obsession with the tests, as well as of a xenoarchaeological dig under the surface of Mars. The dig is excavating the ruins of an ancient civilization discovered on Mars and has produced a relic known as the Soul Cube. According to a scientist the Marine finds in the labs, the Soul Cube is a weapon created by the ancient civilization to defend against the forces of Hell. The scientist also reveals that the invasion began when Betruger took the Soul Cube into the portal at the beginning of the game, depositing it in Hell.<ref name="SoulHell"/> The Marine pursues Betruger through the labs, but is pulled into the main teleportation portal after being lured into a trap by Betruger.

The portal takes the Marine directly into Hell, where he proceeds to fight his way through a large number of demons to the Soul Cube, defeating its demonic guardian. The Marine is then able to reinitialize the teleportation equipment left by previous research expeditions and return to the Delta Labs. Betruger, however, tells the Marine that although the main UAC teleporter has been destroyed, Hell is opening a [[Hellmouth]] on Mars, capable of bringing millions of demons to Mars.<ref name="Hellmouth"/> The Marine encounters the injured Swann, who informs him that Kelly has been working with Hell for possibly the whole time, and has been transformed by the demons.<ref name="SwannPDA"/> Telling the Marine that Campbell has gone after Kelly, Swann gives the marine his PDA containing information on the location on the Hellmouth under the surface of Mars and says that he will try to make his way out of the base alone.

However, when the Marine catches up with Campbell in the central computer processing sector of the base, Campbell is mortally wounded; before expiring, he says that Kelly has taken Campbell's BFG 9000 weapon.<ref name="CPUComplex"/> Kelly then begins to taunt the marine in a demonic voice.<ref name="DemonKelly"/> The Marine eventually faces off with Kelly in the central computer core, revealing Kelly has become a [[cyborg]] grafted onto a tank-like base. The Marine is able to kill Kelly and takes the BFG 9000 before proceeding deeper under the Martian surface to Site 3, the archaeological dig site where the Soul Cube was unearthed. At the primary excavation site, the Marine discovers the Hellmouth, defended by Hell's mightiest warrior, the Cyberdemon. Using the Soul Cube, the Marine defeats the Cyberdemon, and the Soul Cube then seals the Hellmouth. The ending cut scene shows the reinforcements from Earth arriving at the base to discover the carnage. They find the Marine alive but discover that Swann has died from his injuries. They are unable to locate Betruger, who in the final scene is shown in Hell, reincarnated as a dragon-like demon.<ref name="BertDragon"/>

=== ''The Lost Mission'' ===
The player takes the role of the last surviving member of Bravo team, which was seen being ambushed by demons in ''Doom 3''. The Bravo team survivor is contacted by Dr. Richard Meyers (voiced by [[Paul Eiding]]), a scientist working on teleportation experiments in Exis Labs, and asked to help Meyers destroy an experimental teleportation array that was captured by the demons and is currently held deep inside Hell. The array is potentially powerful enough to send an army of demons all the way to Earth, hence Meyers' desperation to destroy it. To achieve this goal, the marine must acquire the components necessary to activate the Exis Labs teleportation system, then travel to Hell in order to destroy the teleportation array. In the epilogue, the marine is teleported by Dr. Meyers back to Mars. The reinforcements from Earth arrive to search for another marine who is still missing; eventually, they find him in the Delta Labs complex.<ref>{{cite news |date=August 2, 2012 |title=''Doom 3: BFG Edition &nbsp;– The Lost Mission'' Trailer |url=http://www.ign.com/videos/2012/08/02/doom-3-bfg-edition-the-lost-mission-trailer |url-status=live |archive-url=https://web.archive.org/web/20150716070427/http://www.ign.com/videos/2012/08/02/doom-3-bfg-edition-the-lost-mission-trailer |archive-date=July 16, 2015 |access-date=July 27, 2015 |website=[[IGN]]}}</ref>

==Development==
===Production===
[[File:John Carmack E3 2006.jpg|thumb|left|The game engine powering ''Doom 3'' was created by [[John Carmack]], who also spurred the initial planning of the project.]]

In June 2000, [[id Software]]'s game engine designer [[John Carmack]], posted an internal company plan announcing a [[Video game remake|remake]] of ''[[Doom (1993 video game)|Doom]]'' using next generation technology.<ref name=".plan"/> This plan revealed controversy had been growing within id Software over remaking ''Doom''. [[Kevin Cloud]] and [[Adrian Carmack]], two of id Software's owners, were always strongly opposed to remaking ''Doom'', believing that id was going back to the same formulas and properties too often. However, after the positive reception to ''[[Return to Castle Wolfenstein]]'' and the latest improvements in rendering technology, most of the employees agreed that a remake was the right idea and presented the two owners with an ultimatum: allow them to remake ''Doom'' or fire them. After the reasonably amicable confrontation (although artist Paul Steed, one of the instigators, was fired in retaliation),<ref name=".plan"/> the agreement to work on ''Doom 3'' was made. id Software began development on ''Doom 3'' in late 2000, immediately after finishing ''[[Quake III: Team Arena]]''.<ref name="HellXbox"/> The game was made by 20 to 22 people.<ref>{{cite web|first=Neil|last=Davidson|url=https://www.newspapers.com/clip/85597695/edmonton-journal/|archiveurl=https://web.archive.org/web/20210920164803/https://www.newspapers.com/clip/85597695/edmonton-journal/|title=Gamer's little bash grows intro major international event|newspaper=[[Edmonton Journal]]|page=18|archivedate=September 20, 2021|date=August 15, 2005|access-date=September 19, 2021|via=[[Newspapers.com]]}}</ref> The game's development budget was $10 million.<ref>{{cite web|url=https://go.gale.com/ps/i.do?p=GPS&u=wikipedia&id=GALE%7CA121083921&v=2.1&it=r&sid=bookmark-GPS&asid=4355a4f4|archiveurl=https://web.archive.org/web/20240920160727/https://go.gale.com/ps/i.do?p=GPS&u=wikipedia&id=GALE%7CA121083921&v=2.1&it=r&sid=bookmark-GPS&asid=4355a4f4|title=Doom 3' Breaks Sales Records; 'Chappelle's Show' Regulars Make The Rounds; Warped Tour: Cheap Seats Ensures Success; Friday Movie Box Office|website=Finance Wire|archivedate=September 20, 2024|date=2004|accessdate=September 20, 2024|via=[[Gale Research]]}}</ref> In 2004, John Carmack estimated that the total cost was as much as $14 million.<ref>{{cite web|first=Michel|last=Marriott|url=https://www.nytimes.com/2004/08/05/technology/in-the-background-a-man-in-the-gaming-forefront.html|archiveurl=https://web.archive.org/web/20180417013007/https://www.nytimes.com/2004/08/05/technology/in-the-background-a-man-in-the-gaming-forefront.html|title=In the Background, a Man in the Gaming Forefront|newspaper=[[The New York Times]]|archivedate=April 17, 2018|date=August 5, 2004|accessdate=March 13, 2025}}</ref> In February 2001, it was unveiled to the public by [[Steve Jobs]] ([[CEO]] of [[Apple Inc.|Apple]] at the time when it unveiled) in [[Macworld Conference & Expo|Macworld Conference & Expo/Tokyo 2001]] along with the [[GeForce 3 series|GeForce 3]] at [[Makuhari Messe]]<ref name="geek.com"/> and was later demonstrated at [[E3 2002]] at [[Los Angeles Convention Center|LACC]], where a fifteen-minute gameplay demo was shown. It won five awards at E3 that year.<ref name="GCA2002"/>

Early in ''Doom 3''{{'}}s development, [[Trent Reznor]] of the band [[Nine Inch Nails]], a fan of the ''Doom'' games and composer for id's earlier title ''[[Quake (video game)|Quake]]'',<ref name="Trent"/> was set to compose the music and sound effects to ''Doom 3''. However, due to "time, money and bad management",<ref name="Trent"/> none of Trent Reznor's sound effects or music made the final product. Eventually, Nine Inch Nails' former drummer, [[Chris Vrenna]], produced and fellow Tweaker band member Clint Walsh composed the game's soundtrack.<ref name="Compose"/><ref name="ChrisVrenna"/>

{{Blockquote|We never really did come to an actual agreement with Trent. The original idea was just for him to do all of the sound design for the game. I don't think Trent anticipated how long and how involved that process was and what is involved in game design versus what he does in the music and production side. It just wasn't a good mix with how much time it was going to take him, the value it was going to provide to the game, and what we could afford to pay. Trent's a popular guy. He's a rock star, and his time is valued in rock star dollars.|Todd Hollenshead the CEO of id Software|title=''The Making of Doom 3''<ref name="TrentStar"/>}}

''Doom 3'' was also intended to be more storyline-focused than previous id titles, as was demonstrated by the developers' conscious effort to have more professional voice acting.<ref name="Voices"/> Late in 2002, two employees at [[ATI Technologies]] leaked a development version of ''Doom 3'' onto the Internet.<ref name="Inquirer"/> One year later, a new trailer was shown at [[E3 2003]] and soon afterwards id Software's website was updated to showcase ''Doom 3'' as an upcoming project, although it was also announced that ''Doom 3'' would not be ready for the 2003 holiday season. According to John Carmack, the development took longer than expected. The developer [[Splash Damage]] assisted in design for the multiplayer elements of the game.<ref name="splash"/> Around 3,000 beta testers on site provided feedback via [[QuakeCon]].<ref name="BetaTest"/> The game's crunch period was between January and August 2004.<ref>{{cite web|first=Matt|last=Stagle|url=https://www.newspapers.com/clip/85645285/journal-and-courier/|title=Gamers prepare to meet their Doom 3|newspaper=[[Journal & Courier]]|page=24|date=August 5, 2004|access-date=September 23, 2021|via=[[Newspapers.com]]}}</ref>

===Technology===
{{further|id Tech 4}}
[[Image:Doom3shadows2.jpg|thumb|right|The shadowing effects of the unified lighting and shadowing engine applied on a group of zombies]]
According to John Carmack, the lead graphics engine developer at id Software, the technology of ''Doom 3'' was supported by three primary features: unified lighting and shadowing, complex animations and scripting that showed real-time with fully dynamic per-pixel lighting and [[stencil shadowing]], and [[GUI]] surfaces that add extra interactivity to the game.<ref name="GSpytech"/> The key advance of the [[id Tech 4]] graphics engine developed for ''Doom 3'' is the unified lighting and shadowing. Rather than computing or rendering lightmaps during map creation and saving that information in the map data, most light sources are computed in real-time. This allows lights to cast shadows even on non-static objects such as monsters and machinery, which was impossible with static non-directional lightmaps. A shortcoming of this approach is the engine's inability to render [[soft shadows]] and [[global illumination]].<ref name="GSpytech"/>

To increase the interactivity with the game world, id Software designed hundreds of high-resolution animated screens for in-game computers. Rather than using a simple "use key" to operate these computers, the crosshair acts as a mouse cursor over the screens allowing the player to use a computer in the game world. This allows for an in-game computer terminal to perform more than one function, from operating security door codes, activating machinery, toggling lights or unlocking weapons lockers. According to the ''Doom 3'' manual, GUI designer Patrick Duffy wrote over 500,000 lines of script code, and generated more than 25,000 image files to create all of the graphical interfaces, computer screens, and displays throughout ''Doom 3''.<ref name="Numbers"/> Other important features of the game engine are [[normal mapping]] and specular highlighting of textures, realistic handling of object [[Game physics|physics]], a dynamic, ambient soundtrack, and multi-channel sound. ''Doom 3'' on [[Xbox (console)|Xbox]] supports [[480p]] widescreen video display resolution and [[Dolby Digital|Dolby Digital 5.1]] surround sound.<ref name="OXM"/>

==Release==
''Doom 3'' achieved [[Software release life cycle#Release|gold status]] on July 14, 2004<ref name="GoldStat"/> and a [[Mac OS X]] release was confirmed the next day.<ref name="InsideMac"/> ''Doom 3'' was released in the United States on August 3, 2004, and to the rest of the world on August 13. Due to high demand, the game was made available at select outlets at midnight on the date of release. Additionally, a [[Linux]] version was released on October 4, 2004, by [[Timothee Besset]]. The Mac OS X version was released on March 14, 2005, and on February 20, 2006, the patch 1.3 Rev A included a [[universal binary]], adding support for Mac OS X on the [[x86 architecture]].<ref name="MacX"/> Finally, the modified Xbox conversion was released on April 4, 2005, featuring a limited steel book edition and two games including ''[[Doom (1993 video game)|The Ultimate Doom]]'' and ''[[Doom II: Hell on Earth]]''.<ref name="pcxbox">{{Cite news |date=February 9, 2005 |title=Doom 3 Xbox port, PC expansion dated worldwide |url=https://www.eurogamer.net/news090205doom3 |access-date=January 9, 2024 |work=Eurogamer.net |language=en}}</ref>

A week before the game's release, it became known that an agreement to include [[Environmental Audio Extensions|EAX]] audio technology in ''Doom 3'' reached by id Software and [[Creative Labs]] was heavily influenced by a [[software patent]] owned by the latter company. The patent dealt with a technique for rendering shadows called [[Carmack's Reverse]], which was developed independently by both John Carmack and programmers at Creative Labs. id Software would have placed themselves under legal liability for using the technique in the finished game, so to defuse the issue, id Software agreed to license Creative Labs sound technologies in exchange for indemnification against lawsuits.<ref name="Gibson"/>

During the keynote address at QuakeCon 2011, John Carmack announced that the source code for the [[id Tech 4|''Doom 3'' engine]] would be released.<ref name="Phoronix"/> The source code was open-sourced under the [[GNU General Public License|GNU GPL-3.0-or-later]] on November 22, 2011. It contains minor tweaks to the shadow rendering code to avoid potential patent infringement with a patent held by Creative Labs. Art assets such as 3D models, music, sound effects etc. remain subject to the EULA.

{{Main|Doom 3: Resurrection of Evil}}
On April 4, 2005, eight months after the release of ''Doom 3'', id Software released an expansion pack for ''Doom 3'' on [[Microsoft Windows|Windows]].<ref name="pcxbox"/><ref name="DM3WinExp"/> The expansion, entitled ''Resurrection of Evil'', was developed by [[Nerve Software]], a company that had partnered with id Software on several other projects, including ''[[Return to Castle Wolfenstein]]'' and the [[Xbox (console)|Xbox]] conversion of ''Doom''.

''Doom 3'' received a favorable reception from critics, with the PC version of the game holding an 87 percent score<ref name="MC"/> and an 88 percent score<ref name="gamerankings"/> at the review compilation sites [[Metacritic]] and [[GameRankings]] respectively. Much praise was given to the quality of ''Doom 3''{{'}}s graphics and presentation; ''[[GameSpot]]'' described the game's environments as "convincingly lifelike, densely atmospheric, and surprisingly expansive",<ref name="gamespot"/> while ''[[PC Gamer UK]]'' described the graphics and [[non-player character]] modeling and animation as simply "flawless", stating that ''Doom 3'' signaled the return of the ''Doom'' franchise to the forefront of the computer and video game industry, eleven years after the release of the original ''Doom''.<ref name="PCGUK"/> ''[[IGN]]''{{'}}s Dan Adams noted that the game's presentation comprised a remarkably high proportion of the game, stating that "without the atmosphere, ''Doom 3'' is a plain shooter that hearkens back to those of the '90s."<ref name="IGNPC"/> In addition, several reviewers praised id Software for making the game still look surprisingly good even on lower graphics levels.<ref name="1UPPC"/><ref name="IGNPC"/>

A number of reviewers also praised the attention paid to the game's premise and setting; GameSpot's [[Greg Kasavin]] described getting "the impression that ''Doom 3'' takes place in a fully realized world"<ref name="gamespot"/> while ''IGN'' noted that "the UAC base also has a very worn and lived-in feel that adds to the realism."<ref name="IGNPC"/> ''[[Eurogamer]]'' in particular pointed out that the game's opening sequence "feels like a fitting tribute to the excellent ideas" of [[Valve Corporation|Valve]]'s genre-defining ''[[Half-Life (video game)|Half-Life]]''.<ref name="EuroG"/>

Many reviewers noted that ''Doom 3'' stuck with a similar "[[Shoot 'em up#Run and gun|run and gun]]" gameplay style that was successful with its predecessors, and the game was alternately praised and criticized for this element. Several reviews were critical of a perceived repetitiveness in gameplay after a while.<ref name="1UPPC"/><ref name="gamespot"/> In addition, the game's [[artificial intelligence in video games|artificial intelligence]] was not regarded as particularly challenging, with GameSpot noting that "enemies follow the same sorts of predictable patterns that [players] may remember from previous ''Doom'' games"<ref name="gamespot"/> while ''[[GameSpy]]'' stated the way enemies would [[spawning (video games)|spawn]] to attack the player was "gimmicky"; the reviewer noted that players would realize that picking up a lone armor vest would cause a variety of zombies to emerge from hidden compartments in the dark.<ref name="gamespy"/> In addition, several reviewers noted that the game's methods of conveying the story were "ineffectual", compounded by the lack of an identity for the [[player character]].<ref name="gamespot"/> Finally, the game's multiplayer was seen as lacking in innovation, with its low player limits and small number of game modes, particularly in contrast to id Software's influential ''[[Quake III Arena]]''.<ref name="gamespy"/><ref name="IGNPC"/><ref name="gamespot"/>

The Xbox version of ''Doom 3'' received a similar level of critical support, holding a score of 88 percent on Metacritic<ref name="MCXBOX"/> and an 87.7 percent score on GameRankings.<ref name="gamerankingsXbox"/> The game was praised and faulted on many of the same issues as the PC version,<ref name="gamespyXbox"/> although the game was praised for maintaining smooth and user-friendly controls on a gamepad, as well as for including a two player co-operative multiplayer mode, which IGN described as "worth the price of admission alone."<ref name="IGNXBOX"/> However, some criticism was directed towards slowdowns in play due to the game engine, despite being scaled down for the Xbox, still being demanding on the Xbox hardware.<ref name="IGNXBOX"/>

}}The ''BFG Edition'' received mixed reviews in comparison. The rework of the graphics and sound design, and inclusion of the new ''Lost Mission'' content were praised. Most criticisms were aimed toward long loading times, forced auto-saves, and a control scheme which forces the player to cycle through their weapons continuously instead of bound to hotkeys as in the original release.

==Legacy==
In early 2008, a new series of ''Doom'' novels by [[Matthew J. Costello]] were published, an author who had worked on the story and scripts for ''Doom 3'' and ''Resurrection of Evil''; previous ''Doom'' novels had expanded the storyline of the original two ''Doom'' games. The series of books aims to [[novelize]] the story of ''Doom 3'', with the first installment, ''[[Doom 3: Worlds on Fire|Worlds on Fire]]'', published on February 26, 2008.<ref name="wof"/> The second book in the series, ''[[Doom 3: Maelstrom|Maelstrom]]'', was released in March 2009.<ref name="Maelstrom"/>

The game engine for ''Doom 3'', id Tech 4, has been licensed out for the use of other developers, such as in [[Human Head Studios]]' ''[[Prey (2006 video game)|Prey]]'', [[Raven Software]]'s ''[[Quake 4]]'', Splash Damage's ''[[Enemy Territory: Quake Wars]]'', [[Raven Software]]'s ''[[Wolfenstein (2009 video game)|Wolfenstein]]'', and Splash Damage's ''[[Brink (video game)|Brink]]''; however id Tech 4 has not been widely licensed compared to [[Epic Games]]' [[Unreal Engine]].<ref name="engines"/> On November 22, 2011, the source code of the engine was released under the [[GNU General Public License|GNU GPL-3.0-or-later]], but the game's artwork content still remains under the EULA. A later source code drop also included the changes made for the ''BFG Edition'', allowing the re-release to potentially be ported to other previously unsupported platforms such as Linux and OS X,<ref name="BFGSupport"/> and such a port was eventually released.<ref name="BFGLinux"/>

===''Doom'' (2016)===
{{Main|Doom (2016 video game)}}

id Software eventually went on to release another title in the series, this time following the series' original roots in minimal storytelling and fast-paced action. Development was announced in 2008, then slated to run on the [[id Tech 5]] engine and initially titled ''Doom 4''.<ref name="Doom4"/> Titled just ''[[Doom (2016 video game)|Doom]]'' and powered by the [[id Tech 6]], the game was released in 2016 by [[Bethesda Softworks]] for Microsoft Windows, Xbox One, and PlayStation 4 with cross-platform support in its "Snapmap" multiplayer mode. A [[Nintendo Switch]] version was released in 2017. It is considered a continuation of the original ''Doom'' storyline.
