Call of Duty 4: Modern Warfare 2™

Call of Duty: Modern Warfare 2 is a first-person shooter video game developed by Infinity Ward and published by Activision for the Xbox 360 and PlayStation 3 video game consoles and the Microsoft Windows operating system. Officially announced on February 11, 2009, the game was released worldwide on November 10, 2009. It is the sixth installment of the Call of Duty series and the direct sequel to Call of Duty 4: Modern Warfare, continuing the same storyline, with Call of Duty: Modern Warfare 3 set to end the storyline. It was released in conjunction with two other Call of Duty games: Call of Duty: Modern Warfare: Mobilized for the Nintendo DS, and Call of Duty: Modern Warfare: Reflex, a port of Call of Duty 4 adapted by Treyarch for the Wii console. In addition, a comic book series based on one of the game's characters was also produced, entitled Modern Warfare 2: Ghost.

Modern Warfare 2 has received very positive reviews from various gaming websites, attaining a 94% aggregate score on Metacritic, with praise stemming primarily from its in-depth multiplayer component. Within 24 hours of release, the game sold approximately 4.7 million copies in North American and the United Kingdom. On August 3, 2011, Activision confirmed that the game had sold over 22 million copies worldwide and it is the second best-selling game of all time in both the UK and the US.

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).

"The healthy human mind doesn't wake up in the morning thinking this is its last day on Earth. But I think that's a luxury, not a curse. To know you're close to the end is a kind of freedom. Good time to take... inventory. Outgunned. Outnumbered. Out of our minds on a suicide mission, but the sands and rocks here stained with thousands of years of warfare... they will remember us for this. Because out of all our vast array of nightmares, this is the one we choose for ourselves. We go forward like a breath exhaled from the Earth. With vigor in our hearts and one goal in sight: We. Will. Kill him."
