The game is played from athird-person perspective and its world is navigated on foot and by vehicle. Throughout the single-player mode, players control Niko Bellic. Anonline multiplayer mode is also included with the game, allowing up to 32 players to engage in both cooperative and competitive gameplay in a recreation of the single-player setting.^[b] Twoexpansion packs were later released for the game,The Lost and Damned andThe Ballad of Gay Tony, which both feature new plots that are interconnected with the mainGrand Theft Auto IV storyline, and follow new protagonists.

Development ofGrand Theft Auto IV began soon after the release ofSan Andreas and was shared between many of Rockstar's studios worldwide. The game introduced a shift to a more realistic and detailed style and tone for the series. Unlike previous entries,Grand Theft Auto IV lacked a strong cinematic influence, as the team attempted an original approach to the story. As part of their research for the open world, the development team conducted extensive field research in New York, capturing over 100,000 photographs and several hours of video. The developers considered the world to be the most important element of the game; though not the largest map in the series, they considered it comparable in scope due to its verticality and level of detail. The budget climbed to overUS$100 million, making it one of themost expensive video games to develop.

Grand Theft Auto IV was released for thePlayStation 3 andXbox 360 consoles in April 2008, and forWindows in December. It received critical acclaim, with praise directed at the narrative and open-world design.Grand Theft Auto IV broke industry sales records and became the fastest-selling entertainment product in history at the time, earningUS$310 million in its first day andUS$500 million in its first week. Considered one of the most significant titles of theseventh generation of video games, and by many critics as one of thegreatest video games of all time, it won year-end accolades, includingGame of the Year awards from severalgaming publications. It is among thebest-selling video games with over 25 million copies sold by 2013. The game generated controversy, with criticism directed at the game's depiction of violence and players' ability todrive drunk. Its successor,Grand Theft Auto V, was released in 2013.

Grand Theft Auto IV is anaction-adventure game played from athird-person perspective.^[2] Players completemissions—linear scenarios with set objectives—to progress through the story. It is possible to have several active missions running at one time, as some require players to wait for further instructions or events. Outside of missions, players canfreely roam the game'sopen world and complete optional side missions.^[3] Composed of the fictional city of Liberty City, the world is larger in area than most earlierGrand Theft Auto series entries.^[4] At the beginning of the game, players can only explore the first island—composed of Dukes and Broker—with all other islands unlocking as the story progresses.^[5]

Players usemelee attacks, firearms and explosives to fight enemies, and may run, jump, swim or use vehicles to navigate the game's world. There is afirst-person perspective option when using vehicles. In combat,auto-aim and acover system can be used as assistance against enemies. Should players take damage, their health meter can be fully regenerated by consuming food or drinks, using medical kits, or calling for paramedics.^[6] If players commit crimes, the game's law enforcement agencies may respond as indicated by a "wanted" meter in thehead-up display (HUD). On the meter, the displayed stars indicate the current wanted level (for example, at the maximum six-star level, efforts by law enforcement to incapacitate players become very aggressive). Law enforcement officers will search for players who leave the wanted vicinity. The wanted meter enters a cool-down mode and eventually recedes when players are hidden from the officers' line of sight.^[7]

The game's cover system allows players to move between cover, to fire blindly, aim freely, and target a specific enemy. Individual body parts can also be targeted.^[8] Melee attacks include additional moves, such as dodging, blocking, disarming an opponent and counter-attacking.Body armour can be used to absorb gunshots and explosive damage, but is used up in the process. When health is entirely depleted, gameplay stops, and playersrespawn at the nearest hospital.^[6]

Thesingle-player mode lets players control anEastern European war veteran,Niko Bellic. During the story, Niko meets and befriends various new characters. They can then perform favours for Niko whenever he asks; for example, his cousin Roman, who owns a taxi service, can send one of hiscabs to take Niko to any destination around the city. Cabs are always available during gameplay for quick travel to a destination. Throughout the course of the game, players are also faced withmorality choices, which alter the storyline appropriately depending on the player's choice. While free roaming the game world, players may engage in context-specific activities such asbowling ordarts. Other available activities include avigilante mini-game, and in-game television programming.^[9][10][11] Niko has acell phone for contacting friends and starting activities.^[12] The cell phone is also used to access the game's online multiplayer mode, and to entercheat codes.^[13] To access the in-game Internet, which allows Niko to send and receive emails and set up prospectivedates with potential girlfriends, Niko can useInternet cafés located around the city.^[14] The game also features asubway system, allowing players to quickly traverse through the game's world.^[15]

Theonline multiplayer mode forGrand Theft Auto IV allows up to 32 players^[b] to freely roam across the map. Players decide which game mode they wish to play, includingdeathmatches and street races. Bothcooperative and competitive game modes are available, split into ranked and unranked matches.^[16] For players to level up through ranks, in-game money has to be earned. The game also features a Free Mode, in which players have the entire map open to explore, with no end goal or mission to complete. Hosts of the game can control many variables, such as police presence, traffic, and weapons.^[17] The multiplayer mode was discontinued on Windows in 2020.^[18]

Grand Theft Auto IV takes place in 2008, within a redesigned version of Liberty City. The design of the city focuses on a recreation of four of the boroughs ofNew York City: Broker (based onBrooklyn), Dukes (Queens), Bohan (The Bronx), and Algonquin (Manhattan). The setting also includes the neighbouring state of Alderney (based onNew Jersey).^[19] Initially, bridges are locked down due to a terrorist threat, and police constantly pursue players if the bridges are crossed. The blockades are lifted as the story progresses, allowing the player to traverse between islands safely.

Grand Theft Auto IV is set in the fictional "HDUniverse", which mirrors and parodies the real world. The previous games formed fictional universes of their own,^[c] which despite having many similarities with the HD Universe, are considered to be different continuities. Hence, the Liberty City depicted inGrand Theft Auto IV is different from its previous renditions, and the game itself serves as areboot for the series. The new timeline established byGrand Theft Auto IV would continue with two expansion packs,The Lost and Damned andThe Ballad of Gay Tony, and a sequel,Grand Theft Auto V, as well as its online component,Grand Theft Auto Online.^[21][22][23] The handheld gameGrand Theft Auto: Chinatown Wars is also considered part of the HD Universe, because it features the same map asGrand Theft Auto IV, except for Alderney.^[24]

Niko Bellic, an Eastern European ex-soldier,^[25] arrives in Liberty City aboard the cargo shipPlatypus to escape his criminal past, pursue theAmerican Dream, and search for the man who betrayed his unit to an ambush during a war ten years prior. Reuniting with his cousin Roman, he discovers that his tales of riches were lies concealing his small, dirty apartment, unprofitable taxi company, gambling debts, and disputes withloan sharks. Niko begins assisting Roman with his problems, which leads him to make his first criminal contacts in the city. He befriendsYardies second-in-command Little Jacob and is forced to work for Vlad Glebov, Roman's Russian loan shark, whom Niko eventually kills upon learning he had slept with Roman's girlfriend, Mallorie.

In retaliation, Niko and Roman are kidnapped byRussian mobsters on orders of their boss Mikhail Faustin and his lieutenant, Dimitri Rascalov. Indifferent to Vlad's murder, Faustin releases them and employs Niko as ahitman, ordering him to kill the son of Russian crime lord Kenny Petrović. When Petrović threatens retaliation, Dimitri convinces Niko to assassinate Faustin and satisfy Petrović. However, Dimitri betrays him after the killing and brings Niko to his former employer, Ray Bulgarin, who accuses Niko of stealing from him during a failedhuman trafficking job years earlier. Niko denies the allegation and a firefight ensues, allowing Dimitri and Bulgarin to escape.

Dimitri's men burn down Niko and Roman's apartment and taxi company, forcing them to flee to Bohan. While Niko finds work with several localdrug lords, Dimitri briefly kidnaps Roman in a failed attempt to lure Niko into a trap. Later, Niko discovers that his romantic interest, a woman named Michelle, is an undercover government agent, who thenentraps him into working for her superior. In exchange for the murders of several known or suspectedterrorists, the superior clears Niko's criminal record and aids him with seeking the traitor. Roman's fortunes improve when he receives a large amount of insurance money from the arson, which he uses to rebuild the business and buy an apartment in Algonquin. Roman also proposes to Mallorie, who accepts.

While working for theIrish Mob, Niko befriends gangster Patrick "Packie" McReary, helping him and his brothers carry out various jobs, including a major bank robbery. Niko is later hired by Ray Boccino, acaporegime in the Pegorinocrime family, to oversee a diamond deal, which goes awry. Boccino repays Niko by helping him find his ex-comrade Florian Cravic, now known as Bernie Crane, who claims he was not the one to betray their unit. Niko realises that the traitor was the only other survivor: Darko Brevic. Niko continues working for theMafia and earns the trust ofDon Jimmy Pegorino, who orders him to kill Boccino after suspecting him of being a police informant. Niko also helps Packie kidnap Don Giovanni Ancelotti's daughter to ransom her for the diamonds, but Bulgarin intercepts the exchange. In the ensuing firefight, the diamonds are lost.

Eventually, government agents find Darko inRomania and bring him to Liberty City for Niko to decide his fate. Afterwards, Niko is summoned by Pegorino for a final favour: to help with a highly lucrativeheroin deal in collusion with Dimitri. He must decide to either work with Dimitri or exact revenge.^[26] If Niko goes through with the deal, Dimitri betrays him again,^[27] kills Pegorino,^[28] and sends an assassin to kill Niko at Roman's wedding, but the assassin accidentally kills Roman instead;^[29] Niko retaliates by tracking and murdering Dimitri.^[28] If Niko chooses revenge, he kills Dimitri aboard thePlatypus,^[30] prompting Pegorino to target Niko at Roman's wedding but accidentally kill Packie's sister Kate, whom Niko had been dating;^[29] Niko retaliates by tracking and murdering Pegorino.^[31] Later, Niko learns that Mallorie is pregnant.

Preliminary work onGrand Theft Auto IV began in November 2004,^[32] a month after the release ofGrand Theft Auto: San Andreas.^[33] Rockstar presidentSam Houser felt that following upSan Andreas was "a nightmare".^[34]Rockstar North, the core 220-person team behind the game, co-opted studios owned by parent company Rockstar Games to facilitate development between a full team of over 1,000,^[35] including 50 employees atRockstar NYC, 40 atRockstar Lincoln, 10 atRockstar San Diego, and around 600–700 working part-time internally and externally.^[36] Some key members of the development team worked 12-hour days during production, often without holidays.^[35] The team decided to continue the numbering scheme absent from the previous two main games to represent the same leap in production asGrand Theft Auto 2 (1999) toGrand Theft Auto III (2001).^[33] Development ofGrand Theft Auto IV ceased by 21 April 2008 when the game wassubmitted for manufacturing.^[37] ProducerLeslie Benzies estimated that the budget of the development efforts exceededUS$100 million, makingGrand Theft Auto IV one of themost expensive video games ever made.^[35]

The game's setting, Liberty City, is based on New York City. The team did not look at the previous renditions of Liberty City as inspiration, wanting it to retain the "general feel" but nothing else.^[38] The map is roughly three times the size ofGrand Theft Auto III's.^[38] The developers originally considered using the entire state ofNew York, before restricting it to Manhattan, and then expanding it out again. They considered including more suburbs with woods, and would regularly vote on which areas to include.^[39] Art director Aaron Garbut said that the team chose the setting because of the detail and variety it provided, describing New York as "an amazing, diverse, vibrant, cinematic city".^[40] WriterDan Houser added that the team "wanted to be somewhere where we had a foothold" due to the amount of research required for the world; Rockstar Games's main headquarters are located in New York.^[41] The team consciously avoided a precise recreation of New York City to allow for more enjoyable game design,^[32] selecting the areas that they felt "characterised it the best".^[40] Garbut wanted to capture a caricature of the city as he felt that most people were familiar with "the highlights" from film or literature but did not need to know the areas precisely.^[40] The city was not built with specific missions in mind; the area was created first, and missions implemented later.^[42]

To achieve a realistic environment, 60–70 employees from Rockstar North travelled to New York for research: first at the beginning of the project in March or April 2005 for a week and a half,^[39] and a smaller trip in 2007.^[38] Police officers who previously worked thebeat drove the team aroundWashington Heights.^[39] A full-time research team based in New York handled further requests for information, such as the ethnic minority of a neighbourhood or videos of traffic patterns. Videos shot in New York were played on televisions at the Rockstar North offices "so while they worked they could look up and there was New York".^[39] Benzies claimed that the team took over 100,000 photographs on location in New York,^[35] though Garbut estimates that they took around 250,000.^[38] They also studied architectural plans for apartments, used satellite images to determine city block layout, researched sales figures for models of cars, and read books that detailed the city's infrastructure, including itssubways, sewers, and garbage disposal.^[43] Hove Beach is based onBrighton Beach, which Sam Houser found "pretty incredible" and unusual; the name is based on the English cityBrighton and Hove, made up of the former neighbouring townsBrighton andHove.^[44] Houser appreciated that Brighton Beach was home to several Eastern Europeans due to the nature of the game's characters.^[44]

Dan Houser described Liberty City as "the biggest character" of the game.^[40] TheGrand Theft Auto IV rendition of Liberty City is more detailed and larger in size than most earlier entries in the series; although smaller than San Andreas, the setting of the previous main game, the developers considered it comparable in scope due to city's verticality, number of buildings, and level of detail.^[45] The team wanted less dead spots and irrelevant spaces, such as the wide open deserts inSan Andreas.^[32] They wanted the game to be "a more focused experience" thanSan Andreas, and Dan Houser felt that the limited activities of New York allowed this.^[33] The team felt that the addition of Niko'smobile phone added to the immersion of the world and represented society's shifted focus on phones.^[33] The in-game brands and products are designed over several years; the billboards were implemented in the game around six months prior to release.^[38]

The game's script, written by Dan Houser and Rupert Humphries, is about 1,000 pages.^[35] Approximately 660 actors provided voices for the game over 80,000 lines of dialogue.^[39] After conceiving the character and setting, Dan Houser spoke with his brother Sam Houser and Leslie Benzies to bounce story ideas before writing a rough synopsis, a six-paged, detailed document. Once the synopsis was reworked, the designers broke it into missions, represented by a large flow document demonstrating each section. The writers then work on the introductions to the missions; the gameplay dialogue comes much later.^[41] Unlike previousGrand Theft Auto games,Grand Theft Auto IV does not have cinematic influences. "We were consciously trying to go, well, if video games are going to develop into the next stage, then the thing isn't to try and do a loving tribute or reference other stuff," said Dan Houser.^[41] He said that the writers wanted something "fresh and new and not something that was obviously derived from [a] movie".^[41] Dan Houser felt that the quality of the writing had to improve alongside the advancements in graphics and technology. He noted that the improvements in facial animation allowed for slower-paced cutscenes.^[40] The unique dialogue that plays when a mission is retried was to ensure that the gameplay felt "less canned and less likeGroundhog Day".^[40]

Dan Houser described Niko Bellic as "a more rounded character" than those in previous games.^[40] He felt that his dual personality—often saving innocent people, while also being a "cold-hearted killer"—made him more relatable.^[40] He also felt that Niko's unfamiliarity with Liberty City allowed for the player to relate to him more, only driven by his vague past and relationship with Roman. When deciding on Niko's background, the writers felt that being an immigrant could lead to more dangerous situations, and therefore more enjoyable missions; after discussions with criminal experts, Dan Houser found that "the real scary characters are not born in America anymore".^[40] He felt that Niko's outsider view ofAmerican culture was "fun".^[40] The team wanted Niko to be "more of ananti hero than a hero, capable of making positive actions within his criminal world".^[46] They wanted his demeanour to reflect the weight of his past and choices.^[46]

Niko's design underwent a few changes, but was finalised early in development.^[47] His outfit underwent several changes based on Eastern Europeans, particularly photographs of men fighting in winter wars inYugoslavia andChechnya. The primary motivation for the design was a face to convey the appropriate emotions and a body that could move nicely with the new animations.^[40] The in-game purchasable outfits were also designed to fit with the character.^[33] The team ensured that thegameplay choices presented to the player were not too extensive, as they still had to make sense to the character, who is driven by the people around him. Dan Houser felt that the missions inSan Andreas had become too linear, and wanted to present choices to the player inGrand Theft Auto IV.^[40]

The writers found that Niko needed a motivation to come to America, so they created his cousin, Roman. Dan Houser felt that the two could not be brothers as there would be a deeper level of familiarity than necessary. He described the two as adouble act, with Roman's fantasist charm playing off Niko's tough cynicism. The team gave othernon-playable characters (NPCs) more definable behaviours and dialogue to make them feel more alive. The writers initially considered having a smaller group of characters, but found that the story became boring and that players were less likely to explore the world. The stranger characters found in the game world were based on the "crazy people" that populate New York, according to Dan Houser, which in previous games were only able to be captured through radio stations or mild pedestrian behaviours.^[38] The team based the ethnicities, clothing, and behaviours of the NPCs on the photographs and videos that they captured around New York, divided into different areas;^[40] they createdmood boards for each location.^[38] The NPCs also converse in different languages.^[39]

Grand Theft Auto IV sees a shift in the series to a more realistic and detailed style and tone, partly a result of the transition to consoles which offeredhigh-definition graphics and the new and improved capabilities of such consoles. The development team worked to represent the upgrade in quality across all design aspects while maintaining the coherence of the previous games.^[32] The team took the game's development as an opportunity to "strip things back and start again", refining the art style without losing the style of the series;^[40] they distanced the game from the "cartoon-like style" of its predecessors while creating a new style that was consistent across all aspects of the game.^[48] Garbut found the increased demand of detail brought on by the advanced technology daunting.^[49] A technique used to make the visuals look real was to avoid harsh edges, instead blending surfaces together to make the world look dirty and lived-in.^[50] Theprops department created multiple variations of different objects to make the world more interesting and unique.^[40]Grand Theft Auto IV was the first contemporary game in the series since 2001'sGrand Theft Auto III; the team felt that enough time had passed to avoid feeling repetitive.^[33] The types of in-game vehicles were decided upon early in development, after which the vehicles department begin creating the designs. The vehicles are not based on specific real-life counterparts, but take elements from several, with some original ideas by the developers.^[51]

The proprietaryRockstar Advanced Game Engine was used forGrand Theft Auto IV.^[53] Garbut found the game's technical design similar toGrand Theft Auto III's, with both being the first in the series released on their respective platforms. He claimed an operablegame engine was not finalised until late in development, at which point "there's still plenty of guesswork" until optimisation near release.^[42] The characters' physical performances were recorded usingmotion capture. Up to eight actors, dressed in full suits, could perform on the motion capture stage at one time.^[52] The camera included ateleprompter for actors to read their scripts.^[54] Over a hundred moves would be captured each day of production.^[52] Thevoice acting performances were often recorded months later alongside facial reference capture,^[55] and an actor's voice could be composited over a different actor's physical performance.^[56] The in-game animations were crafted similarly, using a combination of different motion capture performances.^[57]

For the gameplay and animations, the team redid a lot of the work from previous games, wantingGrand Theft Auto IV to "feel next-generation".^[40] Therole-playing elements fromSan Andreas were removed fairly early in development, partly due to the animation work it would have required, and because consistently needing to visit the gym felt antithetical to Niko's motivations.^[33] The game's targeting system was one of the first focuses of development due to the advanced technology; the team wanted it to feel realistic without being too technical. The cover system was a "natural addition" to the targeting.^[33] Benzies described the multiplayer as the hardest part of the game's development.^[36] The team wanted the multiplayer to feel like an extension of the cinematic single-player experience. Dan Houser described it as "a section of a film rather than the whole narrative".^[33] The developers considered adding co-operative multiplayer to the main story campaign, but decided it worked better as a single-player experience.^[33]

When Sam Houser first showed interest in using theEuphoria software in the game, he was told that it would be impossible or only limited to cutscenes, but some members of the team were able to make it work. Engineers fromNaturalMotion worked on-site at Rockstar North for several months at a time to incorporate Euphoria software into the game.^[34] Rockstar also worked withImage Metrics for the game's facial animations. The facial rigs had around 100 joints, with a total of 300 minutes of facial animation. The scale of the project caused some issues for the animators, forcing them to haverigs completed before animation began. They also faced difficulty in the direction of the actor's head—either straight on when looking at the teleprompter, or down when looking at a script. Image Metrics head of production David Barton noted that "having realistic eyes is 90 percent of the battle", as it allows the player to believe the character.^[54]SpeedTree was used for in-game environment rendering.^[58]

When selecting music for the in-game radio stations, music supervisor Ivan Pavlovich said "[we had] to pick the songs that make New York today what it is, but make sure they won't feel dated by the time the game comes out."^[59] The developers contacted over 2,000 people to obtain recording and publishing rights;^[60] they hired a private investigator to locate the relatives of lateSkatt Bros. memberSean Delaney to license the band's song, "Walk the Night".^[61]Billboard reported that Rockstar paid as much as $5,000 per composition and another $5,000 per master recording per track.^[62] Developers originally considered letting players purchase music in an in-gamerecord shop and for Niko to have anMP3 player, but both ideas were cut.^[60]DJ Green Lantern produced tracks exclusively for the game's hip-hop radio station The Beat 102.7.^[62] Record producer Bobby Konders, who owns the record label Massive B and hosts the in-game radio station Massive B Soundsystem 96.9, flew toJamaica to getdancehall artists to re-record tracks to make references to the boroughs of Liberty City.^[62] The Housers's father, jazz musician Walter Houser, provided several classical music tracks for the game.^[34]

Microsoft'sPeter Moore announcedGrand Theft Auto IV atE3 2006 by rolling up his sleeve to reveal a temporary tattoo of its logo.^[63] The game became widely anticipated.^[64]Wedbush Morgan analyst Michael Pachter suggested Take-Two may delay the game from its 16 October 2007 release date to boost 2008 financial results and avoid competing with games likeHalo 3‍;^[65] Rockstar responded it was still on track for "late October".^[66] In August 2007, Take-Two announced the game would miss its date, delayed to their second fiscal quarter (February–April) of 2008,^[67] citing technical difficulties with the PlayStation 3 version.^[68]IGN predicted the delay would benefit other publishers, particularlyActivision withCall of Duty 4: Modern Warfare.^[69] On 24 January 2008, Rockstar announced the 29 April release date.^[70] Some gameplay features were censored for the Australian and New Zealand versions but the restrictions were subsequently removed.^[71][72]Capcom published the game in Japan on 30 October 2008.^[73]

In August 2008, Rockstar announced that the game would be coming toWindows on 18 November 2008 in North America and 21 November in Europe,^[74] with additional development work byRockstar Toronto.^[75] Microsoft partnered with Rockstar in aUS$50 million deal to bring two episodicdownloadable content packs to the Xbox 360:^[76]Grand Theft Auto IV: The Lost and Damned on 17 February 2009,^[77] andGrand Theft Auto: The Ballad of Gay Tony on 29 October 2009.^[78] Dan Houser wanted the episodes to show "a different side of Liberty City".^[79] In January 2010, Rockstar announced that the DLC would be bundled asEpisodes from Liberty City, released for PlayStation 3 and Windows on 13 April 2010 in North America and 16 April in Europe.^[80]Episodes from Liberty City was also bundled with the main game inThe Complete Edition, released on 26 October 2010 in North America and 29 October in Europe.^[81] The Xbox 360 version of the game and its DLC were madebackwards compatible with theXbox One on 9 February 2017.^[82]

Industry analysts foundGrand Theft Auto IV's marketing much more subtle than Microsoft'smarketing ofHalo 3 (2007), identifying Rockstar's interest in controlling the output at all times.^[83] The game was marketed through video trailers and press demonstrations. On 29 March 2007, the debut trailer was released. It was narrated by protagonist Niko, and depicts the open world accompanied by the song "Pruit-Igoe" byPhilip Glass, originally composed forGodfrey Reggio's 1982 documentary filmKoyaanisqatsi.^[84][85] The trailer is credited for starting theRickrolling meme; after the higher viewership crashed Rockstar's website, several users re-posted the trailer, but some misleadingly played the music video forRick Astley's "Never Gonna Give You Up".^[86][87] The second trailer was released on 28 June 2007, showcasing the game's physics engine and featuring the song "Arm in Arm (Shy Child Remix)" bythe Boggs.^[88] Dan Houser noted that the game was "still rough" when the first trailer was released, but that cutscenes were "coming on board" by the second trailer's release.^[40]

To unveil the game's cover art, Rockstar contracted artists to paint a mural on a wall at a secluded warehouse location, showcasing the art in a video on 28 November 2007.^[89] A third trailer was released on 6 December 2007, introducing some of the game's characters, such as Roman and Michelle. The trailer features the song "King Ring" by Russian rap artistSeryoga, which Rockstar felt captured the "melting pot mentality" of Liberty City.^[90] Dan Houser wanted the third trailer to capture the "visceral qualities" of the game, but focus less on the story, as the first two trailers had done.^[40] On 8 February 2008, five teaser trailers for the game were released, each showcasing a particular character or service within the game.^[91] Similar teaser trailers were later released in pairs on 21 February,^[92] 7 March,^[93] and 11 April.^[94] Another trailer, released on 27 March 2008, showcases some scenes from the game, such as a bank robbery and police chase.^[95] A television commercial fromGameStop debuted on 1 April, focusing on the activities in Liberty City.^[96]

Viral marketing strategies were used to promote the game.Wanted posters were placed around New York City promoting the game's characters and website;^[97][98] billboard versions were also posted throughout the city.^[99] Murals and posters advertising the game were placed on buildings and public transport.^[100][101] TheChicago Transit Authority (CTA) removed advertisements promoting the game from their property in April 2008;^[101] Take-Two filed a lawsuit in response, claiming that the CTA had violated a contract.^[102] Visitors to the website of WKTT Talk Radio—a fictional radio station within the game—were offered a chance to leave a voice mail message stating their problems. Prior to leaving the message, callers were asked to read the terms and conditions, which revealed that some of the voice mail message would be selected for use in the game.^[103]

In the month prior to launch, Rockstar and GameStop held a competition offering up toUS$10,000 and a trip to New York City for the game's launch event.^[104] Microsoft held a similarsweepstakes competition, offering consoles, games,Microsoft Points, abaseball bat, and an invitation to the launch event as rewards.^[105] The officialGrand Theft Auto IV website was redesigned on 8 February 2008 to show a preview of activities and locales within the game's world.^[106] To encourage pre-order sales, Rockstar collaborated with several retail outlets to provide aspecial edition version of the game. It includes a metalsafe deposit box, an art book, and the soundtrack CD.^[107] The publisher also collaborated withSony to release a 40 GB PlayStation 3 console with a copy of the game.^[108] GameStop hosted midnight launch events at over 3,500 of its American stores, with contests and giveaways.^[109]
