Gameplay

Campaign

The player assumes the role of various characters during the single-player campaign, changing perspectives throughout the progression of the story.
Each level is a mission that features a series of objectives that are displayed on the heads up display, which marks the direction and distance towards and from such objectives. Damage to the player is shown by blood appearing on the screen. The player's health regenerates as time passes. Tasks vary in their requirements, from having the player arrive at a particular checkpoint, to eliminating all enemies in a specified location, to defending an objective from enemy attack, or planting explosive charges on an enemy installation. The player is accompanied by friendly troops who cannot be issued orders. Laptop computers that contain enemy intelligence appear throughout the campaign and may be collected.

Cooperative

Call of Duty: Modern Warfare 2 features a cooperative mode titled Special Ops, which consists of independent missions similar in design to the "Mile High Club" epilogue mission from Call of Duty 4. These missions take place in a variety of locations from the campaign mode, but are not related to the campaign. Most of the Special Ops missions may be played alone, but all of them support two player cooperative play in which two players can play together locally or online.Scenarios included are a snowmobile race between the two players, one player providing air support from an AC-130 with the other player conducts operations on the ground, capturing an enemy compound, and searching areas for and eliminating 40 or more enemies at a time.
Special Ops is divided into five separate groups of missions: Alpha, Bravo, Charlie, Delta, and Echo. Each mission may be played at three difficulty levels: regular, hardened, or veteran. Successfully completing a mission earns the players stars; there are up to three stars available for each mission: one star for completing the mission on regular difficulty, two for hardened, and three for veteran. Once enough stars are earned, more missions are unlocked. There are a total of 23 missions with their respective 69 stars available for unlock. At the end of each mission, a statistics screen displays how long the player or players took to complete the level and how many kills were scored by each player, amongst other data.

 Multiplayer

The online multiplayer mode of Modern Warfare 2 retains the same experience points and unlockable reward system as that of Call of Duty 4, with game modes that include Free-For-All, Search & Destroy, Demolition, Sabotage, Domination, Team Deathmatch, and Capture The Flag. Modern Warfare 2 introduces several new features. Aside from new weapons, equipment, and perks that upgrade to "pro versions" after meeting utilization requirements, the player can choose three of fifteen killstreaks, which are earned after getting a certain amount of consecutive kills. Among these is the ability to receive a supply drop after achieving four kills in a row, guide a Predator missile strike after five kills, and control an AC-130 gunship, or Chopper Gunner, after eleven kills. Some killstreak rewards earn kills that go towards your killstreak. For example, Harrier Strike (7 killstreak) will stay and shoot down enemies after it has bombed a general area.Players can also gain a tactical nuke if they obtain a 25 kill streak. The nuke will achieve victory in a match for the player or team that called in the nuke regardless of whether the team was winning or losing at the time the nuke was called in. Another new feature is the in-game host migration; if a match host leaves the game, or if the host struggles to support the game, a 'host migration delay' allows a new host to be selected and the game to continue.There is also the addition of an optional third person mode which can be used in certain game types.
In the Xbox 360 version of the game, the party chat system is disabled while the player is playing online in certain playlist types. This decision, designed to promote cooperation amongst team members, has caused some controversy within the Xbox Live community. The offline (splitscreen and LAN) multiplayer mode retains the experience and rewards system found online, a first for the series since the system was introduced. However, the rewards are separate from those that are earned while playing online.
For the PC version, Infinity Ward decided to implement a new matchmaking service called IWNET, which works through Steam. This system is nearly identical to the console version of IWNET. Dedicated server support is removed, eliminating the ability for mods or user-created maps to be incorporated. This removal has created anger among many PC gamers. Since the multiplayer aspect runs within Steamworks, the PunkBuster anti-cheat system utilized in previous titles has been replaced by Valve Anti-Cheat. In addition, the PC version shares the same 18-player cap as the console versions (matches are a maximum of 9 versus 9).

Modern Warfare 2 was originally referred to under the working title of Call of Duty 6.The game was first announced under the title Call of Duty: Modern Warfare 2 by Activision on December 3, 2008.Activision subsequently retracted its announcement, stating that any information about an upcoming Call of Duty game was "speculative." Infinity Ward then asserted that it had not officially confirmed its latest project at that time. On February 11, 2009, Activision officially announced Modern Warfare 2 and set a tentative release date for "Holiday 2009."The game was tested in an internal beta by the development team. While both Call of Duty 4 and Call of Duty: World at War had been preceded by public multiplayer betas, no such beta was released for Modern Warfare 2 because it was determined that, according to Community Manager Robert Bowling, no public beta was needed unless the internal beta did not provide adequate feedback.
Infinity Ward announced on October 2009 that the PC version of Modern Warfare 2 would not support the use of user-run dedicated servers or in-game console commands. Such announcement was received poorly by some members of the PC community, a negative response that eventually drew Infinity Ward's own response on the matter in an effort to put the community at ease.During brainstorming sessions, an idea came forth on what if the ending of Modern Warfare was a loss, leading to the sequel. In an interview with Jesse Stern, he talked to producers of Infinity Ward with ideas such as "outbreaks, viruses, chemical warfare, and even outlandish things such as aliens and the living dead."Stern mentioned having the game based on real-life conflicts before they halted further planning at first due to events in the 2008 South Ossetia war and in the Mumbai terrorist attacks.

Game engine

The game utilizes the in-house IW 4.0 game engine, which is claimed to be a generation beyond the capabilities of the engine used in Call of Duty 4. Although proprietary, it is based on an unspecified id Tech engine, and can accommodate larger worlds, enhanced graphic detail, and more efficient rendering. Infinity Ward has addressed the issue of enemies that continually respawn at different points of a level The developer demonstrated that the game engine uses a "dynamic AI", which has replaced the infinite respawn system and allows enemies to act more independently. These "smarter" enemies are designed to actively seek out and drive the player forward through a level, and can break away from set behaviors such as following a designated route in order to attack. The player cannot depend on enemies to be found in the same locations as a previous play-through because enemies will behave differently each time a level is played.

Downloadable content

Activision has announced that two downloadable map packs will be released for Modern Warfare 2. At E3 2009, Microsoft stated that these map packs would first be made available for the Xbox 360 via Xbox Live before they would be released for other platforms. Robert Bowling stated that the community response to the game and the first ten downloadable map packs would be used in designing other potential map packs.

Within the first week it had been downloaded 2.5 million times, breaking Xbox Live DLC records. In addition to integrating the maps into all existing game types, the Stimulus Package adds two new game modes, randomizing the built-in game types in either normal or hardcore mode.
Activision released the second downloadable map pack, titled the "Resurgence Package", exclusively for Xbox Live on June 3, 2010 in North America. This release was followed by the PlayStation Network and PC versions on July 6 in North America and on July 7 worldwide.The package includes five new multiplayer maps: reincarnations of the Strike and Vacant maps from Call of Duty 4, and three new maps: Carnival, a desolated amusement park; Trailer Park, a mobile home park; and Fuel, an oil refinery.

Technical problems
