Call of Duty 4: Modern Warfare is a 2007 first-person shooter video game developed by Infinity Ward and published by Activision. It is the fourth main installment in the Call of Duty series. The game breaks away from the World War II setting of previous entries and is instead set in modern times. Developed over two years, Modern Warfare was released in November 2007 for the PlayStation 3, Xbox 360, and Microsoft Windows and was ported to the Wii as Call of Duty: Modern Warfare – Reflex Edition in 2009.
The story takes place in the year of 2011 when a radical leader has executed the president of an unnamed country in the
The game was praised by critics, especially for its gameplay and storyline, but there was criticism of its lack of innovation. Modern Warfare won numerous "Game of the Year" titles and two
A remastered version of the game, Call of Duty: Modern Warfare Remastered, was released as part of special edition bundles of Call of Duty: Infinite Warfare in November 2016 and as a standalone game in June 2017. A reboot of the Modern Warfare game Call of Duty: Modern Warfare, was released in October 2019.
Gameplay
Call of Duty 4: Modern Warfare is a first-person shooter. A character can be in one of three stances: standing, crouching, or prone, each affecting the character's rate of movement, accuracy, and stealth. Using cover helps the player avoid enemy fire or recover health after taking significant damage. As such, there are no armor or health power-ups. When the character has taken damage, the edges of the screen glow red, and the character's heartbeat increases. If the character stays out of fire, the character can recover. When the character is within the blast radius of a live grenade, a marker indicates the direction of the grenade, helping the player to either flee or toss it back to the enemy.
The game is the first in the Call of Duty series to feature modern equipment. The game also introduces new features, particularly multiplayer mechanics such as "killstreaks," where the player gains access to special abilities for killing enemies without dying.
Campaign
The player takes on the role of various characters during a single-player campaign. The characters' involvement in the plot occurs simultaneously and overlaps the events in the game. As such, the player's perspective changes from one character to another between missions. Each mission features a series of objectives; the player is led to each objective with the
Multiplayer
Call of Duty 4: Modern Warfare features team-based and
The player's performance in the multiplayer mode is tracked with experience points, which can be earned by killing opposing players, completing challenges, completing objectives, or by completing a round or match. As the player gains experience, they advance in level, unlocking new weapons, perks, challenges, and gameplay modes. The highest obtainable level is 55, but on the console versions of the game, the player has the option to enter "Prestige" mode, which returns their level to one and removes all accumulated unlockables. This process can be repeated up to 10 times with a different insignia being given each time.[3]
As the player advances in levels and goes up higher in prestige, they earn the ability to customize their classes; this includes selecting their main weapon, sidearm, and special grenade type. Additionally, the player can select 3 perks, one from each of the three "Tiers", that can customize their character further. Perk effects include, but are not limited to, extra ammunition, increasing bullet damage by the player, or dropping a live grenade when the player is killed. The player is also given the choice to complete challenges to receive even more experience points; challenges include achieving a certain number of kills with a specific weapon, shooting down a helicopter, or performing several headshots. Additionally, when the player attains a certain number of headshots with a specific weapon, excluding sidearms, the player unlocks extra weapon "camos", or camouflage, to use for that specific weapon.[1]

Plot
In 2011, a Second Russian Civil War breaks out between the Russian Federation and the Russian Ultranationalist Party, which opposes the government's Westernization efforts and seeks to return Russia to its Soviet-era glory. Meanwhile, the government of an unnamed Middle Eastern country is overthrown in a coup d'état led by Khaled Al-Asad, who holds anti-Western views. In response, the United States invades the country. A platoon of U.S. Marines from 1st Force Recon Company, led by Lieutenant Vasquez, fail to capture Al-Asad and later engage in urban combat in a nearby city with support from an M1 Abrams tank named "War Pig."

A joint task force composed of the SAS, Marines, and Russian loyalists then attempts to capture Zakhaev's son, Victor, to learn Zakhaev's whereabouts. After ambushing him, Victor flees but is cornered on the roof of an apartment building, committing suicide to avoid capture. Enraged, Zakhaev retaliates by seizing control of a Russian nuclear launch facility.

Development
Call of Duty 4: Modern Warfare was developed by a team of a hundred people, over the course of two years. After
The development team designed the online multiplayer component to be balanced and rewarding for new players while still offering something for experienced players. An early idea to implement air support (air strikes and attack helicopters) involved players fighting over special zones to access a trigger for air support against enemies. This idea was discarded because it discouraged the type of deathmatch gameplay they intended. The killstreak reward system was put in its place to encourage the improvement of player skills. Players were allowed to select weapons before matches to get accustomed to weapons more easily and minimize weapon hunting. Maps were designed primarily for deathmatch games—the developers felt such designs suited other types of gameplay as well. Map layouts were designed to minimize locations players could hide from enemy gunfire.[5]
Most of the music for Call of Duty 4: Modern Warfare was written by British composer Stephen Barton, who had also contributed to film scores by Harry Gregson-Williams, to whom, composed the main theme of the game. Several music tracks from the game are available on Infinity Ward's "7 Days of Modern Warfare" website, and some are available at Barton's own web site.[6] The rap song played during the end credits is performed by Call of Duty 4's lead animator, Mark Grigsby.[7]
Game engine
Call of Duty 4: Modern Warfare runs on the
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. Bullet stopping power is decreased after penetrating an object, and the decrease is dependent on the thickness and surface type of the object. The game makes use of a dynamic
The game engine has also been used for the development of two other Activision games. An enhanced version of the original engine was used in Call of Duty: World at War, the fifth installment in the Call of Duty series after Call of Duty 4: Modern Warfare,[12] while a slightly altered version has been used for the James Bond video game Quantum of Solace, as well as GoldenEye 007 using a heavily modified version.[13]
Marketing and release
On April 27, 2007, the day before the release of the game's trailer, Infinity Ward launched a website called "Charlie Oscar Delta" to provide information on the game. Charlie Oscar Delta features a ranking system that allows users to complete missions to increase their rank and compete for prizes. Charlie Oscar Delta is derived from the

This patch can be applied to the Game of the Year edition directly with no prior patches. Earlier versions must have patch 1.6 applied first.[33]

Critical response
Call of Duty 4: Modern Warfare received "universal acclaim" on the PlayStation 3, Xbox 360, and PC versions, and "generally favorable reviews" for the Wii version, according to
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."
Nevertheless, the game has also received criticism.
Wii version
Modern Warfare – Reflex Edition was ported by Treyarch. The Wii version of Call of Duty 4: Modern Warfare has fewer features than the other console versions. It does not support split-screen multiplayer, and the graphics are not as developed. However, it supports co-operative gameplay in the campaign on a single screen. At any moment, a second Wii remote can be activated giving the second player their own aiming crosshairs. The game received an aggregated score of 76% on Metacritic.[70] IGN gave the Wii version of the game, Call of Duty: Modern Warfare – Reflex Edition, a score of 7.0, saying the visuals and pointer controls are not as polished as the Wii version of World at War, though they did mention the customization options and multiplayer are impressive.[71] Official Nintendo Magazine gave it 80%, praising it for packing everything from its next-gen counterpart, but again criticizing the visuals.[72] GameTrailers gave the game an 8.8, saying that despite some sacrifices, it retains everything good from its original version.[73] Game Informer scored the game at a 6.5, stating that while the game was rather poor graphically, even by Wii standards, the bigger problem was the Wii remote, stating that it did not have enough buttons to support Modern Warfare's control scheme, and also that it was quite imprecise, contrasting it with the dual analog system used by the PlayStation 3 and Xbox 360 versions, and the mouse and keyboard system on the Windows version of the game. GameSpot gave the game an 8.5, stating that the online was as addictive as the other versions, they also said that the controls "are precise and customizable enough to let you be all you can be".[74]
Legacy
Call of Duty 4: Modern Warfare spawned two sequels: Modern Warfare 2 and Modern Warfare 3, which were released in 2009 and 2011, respectively.[75] A remastered version of Modern Warfare, titled Call of Duty: Modern Warfare Remastered, was developed by Raven Software.[76] The remaster was first released as part of several special editions of Call of Duty: Infinite Warfare when that game was released for Microsoft Windows, PlayStation 4 and Xbox One, followed by a standalone release for PlayStation 4 in June 2017, and for Microsoft Windows and Xbox One in July 2017.[77][78] A reboot of all three Modern Warfare installments, developed by Infinity Ward and simply titled Call of Duty: Modern Warfare, was released in October 2019.[79]
Sales
Predictions for Call of Duty 4: Modern Warfare's indicated it would gross more than Halo 3 in September that year. It was reviewed as highly as Halo 3's but was launching on three systems as opposed to one. Demand for the game led to several retailers only having enough copies available to satisfy pre-orders.[80]
It fulfilled the prediction, with the
