Call of Duty 4: Modern Warfare is a first-person shooter video game developed by Infinity Ward and published by Activision for Xbox 360, PlayStation 3, and Windows; it is also scheduled for release for Mac OS X in May 2008.[5][6][4] It is the fourth installment of the Call of Duty video game series, excluding expansions. The game breaks away from the World War II setting of previous games in the series and is instead set in modern times. It is also the first game in the series to be rated Mature in North America. The title and game details were announced on April 25, 2007,[7] and it was released worldwide between November 6 2007 and November 9, 2007. The game also became available on Steam on November 6, 2007 for pre-purchase, and was available to play on November 12, 2007.[8]

The story is set in a fictional near-future war between the United States, United Kingdom, and Russian Loyalists against Russian Ultranationalists and Middle Eastern rebels, and features real-world weapons and vehicles. It is told from the perspective of both a United States Marine and a member of the British SAS, and is set in multiple locations, including the Middle East, Azerbaijan, Russia, and Prypiat, Ukraine. The multiplayer portion of the game features different game modes, and contains a leveling system which allows the player to unlock additional weapons, weapon attachments, and camouflage schemes as they advance.[9] The game has been in development for two years, and uses a proprietary game engine, and includes features that include true world-dynamic lightning, HDR lighting effects, dynamics shadows, and depth of field.[10]

Call of Duty 4: Modern Warfare received almost universal praise, winning multiple awards at gaming websites, and being complimented on its storyline, visual elements, realism, and quality of its multiplayer gameplay.[11][12] The game was predicted to sell more copies for the Xbox 360 than Halo 3 because Call of Duty 4 was sold out at stores, it garnered the same averaged score as Halo 3, and it was launching on four systems opposed to one for Halo 3.[13] It managed to become the top-selling game for the Xbox 360 in the United States from November 2007 to January 2008.[14][15][16] Call of Duty 4 has gone on to sell more than seven million copies worldwide when adding up units sold for all consoles, as of January 2008, becoming the best-selling game of 2007.[17]

Gameplay

Call of Duty 4: Modern Warfare is a first person shooter similar to previous games in the Call of Duty series, but is set in present-day warfare instead of the World War II setting that previous games in the series featured.[18]

The series' move to modern warfare introduces new weapons and technology to the Call of Duty franchise, including the M203 grenade launcher, M4A1 carbine, the AN/PEQ-2 Target Pointer for use in conjunction with night vision goggles, the MP5SD submachine gun, and the FGM-148 Javelin portable anti-tank guided missile.[9] The player gains access to these over the course of the game, but may only carry up to two weapons in addition to a service pistol and grenades. Weapons from fallen foes can be picked up to replace weapons in a player's arsenal. A number of additional abilities are also present, such as a grenade launcher attachment, night-vision googles, and the ability to call in airstrikes.[9]

The gameplay of Call of Duty 4 shares several features with previous iterations of the franchise. Once again, players fight alongside several AI-controlled teammates. They help to proceed through the game's missions by providing cover fire, shooting down enemies, and clearing rooms for entry.[9]

A player can perform one of three stances: standing, kneeling, and prone; each affects the player's rate of movement, accuracy, and stealth. The game emphasizes the use of cover with these stances to avoid enemy fire or to recover health after taking significant damage, as there are no armor or health powerups. When the player has taken damage, the edges of the screen glow red and the character's heartbeat increases in volume. If the player stays out of fire for a short period, the player can recover. When the player is within the blast radius of a live grenade, a marker indicates the direction of that grenade to warn the player to either flee or toss it back to the enemy.[9]

Campaign

Similar to previous games in the series, the player takes on the role of different characters over the course of the game in the single-player campaign. These characters' involvement in the plot occur simultaneously and overlap over the events in the game. As such, the player's perspective can change from one character to another between missions.[9]

Each mission features a series of objectives; the player is led to each objective with the head-up display, which marks its direction and distance. Some objectives require that the player arrives at a checkpoint, while other objectives require the player to eliminate enemies in a specified location, stand their ground to defend an objective, or plant explosive charges on an enemy installation. The player is often accompanied by friendly troops, but they cannot issue orders. A series of computer laptops appear throughout the campaign, which contain enemy intelligence and can be collected to unlock game bonuses.[9]

After completing the campaign, a special epilogue mission is unlocked for play. The mission itself has no bearing on the campaign plot, and focuses on an SAS squad fighting terrorists that have hijacked an airplane and taken a VIP hostage.[9]

Multiplayer

Capturing a flag in Domination mode

Call of Duty 4 features several team-based and deathmatch-based multiplayer modes on different maps. Each mode has an objective and require a unique strategy to complete the mission.[19] Players can call in UAV reconnaissance scans, air strikes, and attack helicopters to assist their team by achieving a three-, five-, or seven-enemy kill streak, respectively.[9] A game ends when either a team has reached a predefined number of points, or the time limit has run out, thereby selecting the team with the most points as the winning team.[19]

The player's performance is tracked in the multiplayer mode with experience points earned by taking down other players, completing objectives, or simply by being a member of the winning team. As the player gains experience, they advance in level, unlocking new weapons, perks, challenges, and gameplay modes that they can participate in. The highest obtainable level is 55, but on the console versions of the game, the player has the option to play "Prestige" mode; this resets their level back to 1 and lose all earned bonuses in exchange for a special in-game insignia. This process can be repeated up to ten times with a different insignia being given each time,[20] giving the player a total of 605 levels to achieve.[21] Leaderboard statistics, including kills, deaths, and playing time, are not affected by Prestige mode.[22]

Completing a challenge grants experience points, which can be used to unlock new weapons, perks, or other bonuses. At lower experience levels, the player only has access to five pre-determined classes, and cannot create a custom class with the weapon of their choosing. However, as the player advances in levels, they earn the ability to customize their classes. This includes selecting their main weapon, side arm, and grenade type. Additionally, the player can select a limited number of "perks" that can customize their character further. Perk effects include increasing damage by the player, being able to take more damage, or detonating a grenade after being killed in an act of martyrdom. The player is also given a number of challenges to attempt, including achieving a certain number of kills with a specific weapon and performing a number of specific types of shots.[9]

Synopsis

Characters

See also: Characters in Call of Duty

During the single-player campaign, the player controls several characters from a first-person perspective. Sergeant "Soap" MacTavish, a member of the 22nd SAS Regiment, is the first person that the player controls. The player assumes the role of MacTavish for the majority of the game, starting with his enrollment in the 22nd.[18] Sergeant Paul Jackson is part of the USMC 1st Force Recon deployed to the Middle East, and the player assumes Jackson's character during five levels of Act 1. Captain/Lieutenant Price is an officer of the 22nd SAS Regiment who is playable in a flashback. Yasir Al-Fulani is the president of the unnamed Middle Eastern country mentioned in the game, and is playable only in the game's opening credit sequence. The player also assumes the role of an American thermal imaging TV operator aboard an AC-130 gunship for one level, as well as a British SAS counter-terrorist operative infiltrating a hijacked airliner to save a VIP in the epilogue level.[23][19][18]

There are several non-playable characters (NPC) who feature prominently in the story. Captain Price (in his NPC capacity) and his right-hand man, Gaz, serve as mentors to MacTavish. Jackson's USMC platoon commander is Lieutenant Vasquez. USMC Staff Sergeant Griggs first serves alongside Jackson in the Middle East campaign, and later accompanies MacTavish in Russia. Sergeant Kamarov leads the Russian Loyalists that ally with the SAS and USMC forces. The villains in the story are Khaled Al-Asad, the commander of the revolutionary forces in the Middle East and an ally of Imran Zakhaev; Victor Zakhaev, the son of Imran Zakhaev and a priority figure in the Ultranationalist party; and Imran Zakhaev, the leader of the Russian Ultranationalist party and the main antagonist of the game.[19]

Plot

The game begins with British 22nd Special Air Service Regiment Sergeant "Soap" MacTavish, Captain Price, Gaz, and a small group of other SAS members infiltrating a cargo ship in the Bering Sea. After eliminating the enemy sailors and confirming the presence of a nuclear device onboard, the vessel comes under attack from hostile MiGs. The team manages to evacuate the sinking ship with the cargo manifest, which proves there are ties between a Russian nationalist group and a faction in the Middle East.[19]

Meanwhile, Russian Ultranationalist Imran Zakhaev is set on returning his homeland to the times of the Soviet Union by revolting against the current government and seizing a nuclear weapons stockpile. Zakhaev funds a coup d'état in an unnamed Middle East oil-producing nation, organized by his ally Khaled Al-Asad. It begins with the televised execution of President Yasir Al-Fulani. The British and American governments discover the plot while monitoring Zakhaev's recent activities, and initiate a police action to stop the uprisings in both regions.[19] After President Al-Fulani is executed, the 22nd SAS is deployed to rescue their compromised informant, who is held in an Ultranationalist camp in Russia, with help from Russian Loyalist forces led by Sergeant Kamarov. Before they can reach the base in Hamburg, their helicopter is shot down over Central Russia. An AC-130 gunship is dispatched to provide fire support for the team until they are evacuated.[19]

Not long after Al-Asad's coup, the United States invades the Middle Eastern country, using Marine Corps air cavalry to secure a port. A platoon from the USMC 1st Force Recon led by Lieutenant Vasquez searches the city for Al-Asad, securing the television station broadcasting rebel propaganda, but failing to find the revolutionary leader. During the night, while the main USMC forces push Al-Asad's forces back to the capital city, Vasquez's men secure a disabled M1A2 Abrams main battle tank and escort it back to the highway. They are then airlifted to take part in what appears to be the final stages of the conflict, when United States Central Command is notified by the SAS of a Russian nuclear weapon nearby, and sends a team to disarm it. With Command ordering the evacuation of Marines as a precaution, Vasquez's platoon helps to extricate an advance team pinned by enemy fire. The nuclear device nevertheless detonates, leveling the city and killing the United States Marine forces in the area. Vasquez's men, delayed from escaping the blast radius due to the last minute rescue of a downed AH-1 SuperCobra pilot, are aboard one of the helicopters caught in the blast radius. Jackson initially survives the crash of his squad's CH-46 Sea Knight helicopter; however, he dies soon thereafter.[19]

It is revealed that Al-Asad had fled the country prior to the United States-led invasion. The informant "Nikolai" directs the 22nd SAS to one of Al-Asad's safe houses in Azerbaijan. After interrogating Al-Asad and learning Zakhaev had supplied the nuclear bomb, Captain Price executes Al-Asad.

Price then has a flashback of his mission to eliminate Zakhaev in Prypiat, Ukraine, fifteen years ago. In the aftermath of the Chernobyl disaster and the collapse of the Soviet Union, Zakhaev took advantage of the turmoil to profit from nuclear proliferation and used his new wealth to lure soldiers from the Soviet Army and form his Ultranationalist breakaway faction. Price, who was a lieutenant with the SAS, was paired up with Captain MacMillan to carry out the assassination on the British government's orders. While Zakhaev was engaged in an arms deal, the SAS commandos used the opportunity to target him with a sniper rifle. Zakhaev survived, however, but lost his left arm. The Ultranationalist forces tracked the shot and pursued the snipers across the Zone of Alienation. During the chase, MacMillan was injured and Price was forced to carry him to the evacuation zone, narrowly escaping the enemy.[19]

Returning to the present, the Ultranationalists launch a counterattack against the 22nd SAS. From the village where the safehouse is, Captain Price's men briefly hold out against the assault before they are extracted by American forces, led by Staff Sergeant Griggs, who recently served alongside Sergeant Jackson in the USMC campaign in the Middle East. A joint operation, comprised of the 22nd SAS Regiment under command of Captain Price, a USMC Force Recon unit led by Staff Sergeant Griggs, and Russian Loyalists led by Sgt. Kamarov, is undertaken to stop Zakhaev. They attempt to capture his son Victor to learn of his whereabouts, but this mission ends in failure when Zakhaev's son commits suicide after being cornered.[19]

Imran Zakhaev becomes enraged, blaming Western forces for the death of his son, and plans to retaliate by launching SS-27 Topol M ballistic missiles with MIRV warheads at the East Coast of the United States. Price's men and Griggs try to stop this by sabotaging the electricity grid but their efforts fail to prevent the launch of two warheads. The Ultranationalists are well-entrenched in the missile launch center, having earlier eliminated the loyalist Spetsnaz commandos trying to retake the facility, but the SAS-USMC operatives are able to overcome them and deactivate the missiles before they reach their target. Zakhaev's reinforcements surround the missile silos and the joint force commandeers a jeep to make their escape.

During their escape, an enemy Mi-24D Hind gunship destroys the bridge they are attempting to cross, leaving them trapped. Zakhaev's troops arrive soon after, and begin engaging the remaining members of the strike force. A wrecked gas tanker on the bridge explodes, incapacitating everyone except Griggs. Griggs is then shot in the neck while trying to pull Soap to safety. Then Zakhaev himself arrives, accompanied by two soldiers. Gaz is shot in the head by Zakhaev. Zakhaev is on the verge of killing Soap, but is distracted by the destruction of the Mi-24 Hind followed by the arrival of a Russian Loyalist Mi-28 helicopter. At this moment, a heavily wounded Captain Price slides his pistol to Soap, who then kills Zakhaev and his guards. As MacTavish is airlifted from the battleground, a Russian Loyalist medic is seen desperately attempting to resuscitate Price.

After these events, news reports mention "nuclear missile tests" in Central Russia, "leadership struggles" arising in the Ultra nationalist party, and the failed attempt to locate a Russian cargo ship lost in the Bering Strait (presumably the cargo ship the 22nd SAS had invaded), implying that the recent police actions in Russia were conducted in secret, and were not public knowledge.[19]

Call of Duty 4 was in development for two years, with a team composed of a hundred people.[25] After completing development for Call of Duty 2, the Infinity Ward team decided to go in a different direction from the World War II environment of previous games in the series. They came up with two game concepts, which resulted in Call of Duty 4: Modern Warfare and an unnamed game set to be released in the future.[25]

While developing the story for Call of Duty 4, Infinity Ward chose to avoid referencing any current, real wars, but kept the common theme from the series of two large opposing forces similar in strength. To make the game feel more realistic, the development team attended a live-fire exercise at 29 Palms, a Marine training facility in the California desert. This experience was applied to the effect that happens in the game when a player is near an Abrams tank that fires. The team also talked with United States Marines who were only recently in combat to get a feel for the background, emotions, and attitude of soldiers in combat. Veterans were also recruited to supervise motion capture sessions and artificial intelligence design of the game.[25]

Game engine

File:Cod4 game engine.jpg
An example of the lighting, shadows, and weather effects in the game's single-player mode.

Call of Duty 4: Modern Warfare runs on a proprietary engine, and with features that include true world-dynamic lighting, HDR lighting effects, dynamic shadows, and depth of field.[10] "Bullet Penetration" is calculated by the engine, taking into account factors such as surface type and entity thickness. Certain objects, such as cars and some buildings, are destructible. This makes distinguishing cover from concealment important, as the protection provided by objects such as wooden fences and thin walls do not completely protect players from harm as they do in other games released during the same time period. Bullet speed and stopping power are decreased after penetrating an object after calculating the thickness and surface type of the object. The game also makes use of a dynamic physics engine, which was not implemented in previous Call of Duty titles. Death animations are a combination of pre-set animations and ragdoll physics. Console versions of Call of Duty 4: Modern Warfare run at a consistent 60 fps.[10]

Audio

The music for Call of Duty 4: Modern Warfare was composed by British composer Stephen Barton, who also contributed music to films scored by Harry Gregson-Williams. Gregson-Williams also composed some additional music for the game, such as the main theme. Several selected music tracks from the soundtrack available on Infinity Ward's "7 Days of Modern Warfare" website, with additional tracks available at Barton's own web site.[26] The rap song played during the end credits is performed by Call of Duty 4's lead animator, Mark Grigsby.[27]

Marketing and release

On April 27, 2007, the day before the release of the game's official trailer, Infinity Ward launched a website called "Charlie Oscar Delta" to provide information on the game. Charlie Oscar Delta features a ranking system which allows users to complete missions to increase their rank and compete for prizes. Charlie Oscar Delta is derived from the NATO phonetic alphabet and the initials of Call of Duty .[28]

The first Call of Duty 4: Modern Warfare trailer featuring game footage was released on April 28, 2007.[29] An Xbox 360 Call of Duty 4: Modern Warfare public beta test was announced on August 30, 2007. The beta test was designed to test the servers, find glitches, and help balance out the weapons. It was originally only for residents of the United States of America but was later available to other countries. The beta concluded on September 30, 2007.[30] The maximum rank for the beta was initially level 16,[31] but was increased to level 25 towards the end of the beta. Three multiplayer maps were available for play: Crash, Vacant, and Overgrown.[32]

A single-player demo for the PC was released on October 11, 2007 as a Yahoo! exclusive download. It was released on various major sites the same day, and is now available for free download. The demo includes one level, "The Bog", which showcases the advanced night vision, and associated graphics capabilities, used in Call of Duty 4: Modern Warfare.[33]

Retail versions

The game was released as a Standard Version and a Collector's Edition. The Collector's Edition contains the standard retail game along with a DVD containing a documentary film (168 minutes) entitled "Great SAS Missions" which consists of archive footage of the SAS in action, along with interviews and accounts from former SAS members. The DVD also contains A 'Making of' Call of Duty 4: Modern Warfare featurette and a level walkthrough by the developers. Also included is a limited edition Call of Duty 4: Modern Warfare poster and an exclusive hardcover art-book featuring never-before-seen concept, development, and final in-game artwork. These elements were packaged in a larger cardboard version of the standard retail box. The Collector's Edition was originally only available in the United States, but was later released in other countries.[34]

Downloadable content

Infinity Ward released the Variety Map Pack as a timed exclusive for the Xbox 360 on April 4, 2008. It includes the stages "Killhouse", "Creek", "Chinatown", and "Broadcast". The same map pack was released for the Playstation 3 on April 24, 2008. A release date for the PC version is yet to be announced. The Variety Map Pack was downloaded by over one million people in its first nine days of release, a record for paid Xbox Live downloadable content, valued at US$10 million.[35]

Reception

All three versions of Call of Duty 4: Modern Warfare have received favorable reviews from video game publications. The Xbox 360 version received an average score of 94% based on 72 reviews on the review aggregator Game Rankings,[57] and an average score of 94 out of 100 based on 69 reviews on Metacritic,[58] The PS3 version received an average score of 94% based on 43 reviews on Game Rankings,[59] and an average score of 94 out of 100 based on 43 reviews on Metacritic.[60] The Windows version was also received favorably, achieving an average score of 93% based on 39 reviews on Game Rankings,[61] and an average score of 92 out of 100 based on 37 reviews on Metacritic.[62]

The gameplay has been cited by reviewers to bring the genre to "a new level of immersion and intensity that we had never seen before".[63] Official Xbox Magazine said about the multiplayer, "it’s the multiplayer mode that solidifies the game’s instant-classic status" and that "the campaign never lets up".[64] GameSpot gave a favorable review for Call of Duty 4: Modern Warfare, saying that the "high quality of that campaign and its terrific multiplayer options make Call of Duty 4 a fantastic package".[37] X-Play commented that "while it may not have revolutionized the genre, it comes damn close to perfecting it".[38] GamePro claims that "the amazingly deep multiplayer rivals Halo 3's in terms of reach and scope".[36]

The game's story has received a considerable amount of acclaim from reviewers. GamePro notes that "the intense single-player campaign offers up an action packed experience that features a tremendously compelling narrative; there are moments in the game that will send chills down your spine".[36] GameSpot mentioned that the "single-player campaign is over in a flash" as the only major flaw.[37] While IGN described the campaign as "still very linear" like that of its predecessors, "eschewing the concept of sandbox gameplay", it noted that this resulted in "a much richer, more focused experience" with "beautifully scripted set pieces".[65] Despite the praise, Call of Duty 4 has also received some criticism. Xbox World 360 disliked the game, stating, "It's smoke and mirrors and a host of cheap tricks", commenting on the fact that the game did not revolutionize the genre.[66]

Awards

Call of Duty 4: Modern Warfare received a number of awards from various game sites and gaming authorities. Both GameSpot and GameTrailers gave it the Best Graphics of E3 2007 award, and the Best PlayStation 3 Game of 2007 award.[42][44][45] It gained high praise from both video game magazine GamePro and GameSpy, having been named the Best Overall Game of 2007 by the former,[46] and Game of the Year by the latter.[50][51][52][53] Game Critics also named the game "Best Action Game".[41] From other authorities such as IGN and X-play, and the Spike Video Game Awards, the game won various other awards for areas such as Best Sound Design, Best Shooter of 2007, and Best Military Game. Lastly, from the Academy of Interactive Arts & Sciences, Call of Duty 4: Modern Warfare won Console Game of the Year, Action game of the Year, and Overall Game of the Year.[56]

Sales

Even before Call of Duty 4 was released, it was predicted to sell more copies for the Xbox 360 than Halo 3 because Call of Duty 4 was sold out at stores, it garnered the same averaged score as Halo 3, and it was launching on four systems opposed to one for Halo 3.[13] Despite not fulfilling this prediction, it managed to become the top-selling game for the Xbox 360 from November 2007 to January 2008. It sold 1.57 million units in November 2007,[14] and 1.5 million units in December.[15] It was also the top-selling game for January 2008, selling 331,000 copies for the Xbox 360 and 140,000 copies for the PlayStation 3.[16] Call of Duty 4 has gone on to sell more than seven million copies worldwide when adding up units sold for all consoles, as of January 2008, becoming the best-selling game of 2007.[17]

Call of Duty 4 is a target of piracy, which may affect the game's sales. One of the game's developers stated, "We pulled some disturbing numbers this past week about the amount of PC players currently playing Multiplayer [...] What wasn't fantastic was the percentage of those numbers who were playing on stolen copies of the game on stolen / cracked CD keys of pirated copies."[67]
