Call of Duty: Modern Warfare 2

"The most anticipated game of the year— Modern Warfare 2."

- Adam Sessler, co-host of X-Play

Call of Duty: Modern Warfare 2 (Sometimes referred to as Modern Warfare 2) is the sixth main Call of Duty game, and the fourth developed by Infinity Ward.

The game was published by Activision for Microsoft Windows, PlayStation 3, and Xbox 360. Officially announced on February 11, 2009, the game was released worldwide on November 10, 2009. It is the direct sequel to Call of Duty 4: Modern Warfare, continuing along the same storyline and gameplay. 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 highly positive reviews from various gaming websites, attaining a 94% aggregate score on Metacritic, with praise stemming primarily from its in-depth multiplayer component. Upon its release, the game sold approximately 4.7 million copies worldwide in 24 hours. On June 15, 2010, Activision confirmed that the game had sold over 20 million copies worldwide.

Plot overview
"This is for the record."

- Captain Price

Despite the efforts of the United States Marine Corps and the Special Air Service, the Ultranationalists seize control of Russia and declare Imran Zakhaev a hero and martyr, erecting a statue of him in the heart of Red Square. Meanwhile, Vladimir Makarov, one of Zakhaev's former lieutenants, begins a campaign against Europe by committing acts of terrorism over the course of five years. In Afghanistan, U.S. Army Ranger Joseph Allen assists in the taking of a city from insurgents. Impressed by Allen's abilities, Lieutenant General Shepherd recruits him into "Task Force 141", an elite, multi-national counter-terrorist unit under Shepherd's command. Meanwhile, two other members of 141, John MacTavish and Gary Sanderson infiltrate a Russian airbase in the Tian Shan mountains to retrieve an ACS (Attack Characterization System) module from a downed satellite.

thumb|left|300px|Introduction to the gameAllen is later sent on an undercover mission in Russia for the CIA, joining Makarov in a massacre of civilians at the Zakhaev International Airport in Moscow. Makarov has been aware of Allen's identity and kills him during extraction, leaving his body to spark a war between Russia and America. Angered by what was believed to be an American-supported terrorist attack, Russia retaliates with a massive surprise invasion on the United States after bypassing its early warning system, revealing that the ACS module MacTavish and Sanderson recovered had already been compromised before its retrieval. Sergeant Foley leads his squad of Army Rangers, including James Ramirez, in defense of a suburb in northeastern Virginia against the Russian invasion. They then proceed towards a war-torn Washington, D.C., where U.S. forces are fighting the Russians for control of the capital.

Meanwhile, 141 searches for evidence that implicates Makarov as the mastermind behind the airport massacre, as all proof of Makarov's involvement died with Allen. Intelligence leads them to a Favela, where the team investigates leads on Makarov's contact, weapons dealer Alejandro Rojas. They find out from Rojas that Makarov's worst enemy, known as Prisoner 627, is locked up in a Russian gulag. The Task Force assaults the prison and manages to free 627, who turns out to be Captain Price. Price agrees to aid Soap and Shepherd in tracking down Makarov. Price decides that ending the war in America is their first priority. To end it, he temporarily goes rogue, and leads them to raid a Russian port, where they gain control of a nuclear submarine. Price uses the submarine to launch a ballistic missile towards Washington D.C. He sets the warhead to detonate in the upper atmosphere, which destroys the International Space Station and creates an electromagnetic pulse, which cripples vehicles and electronic equipment on both sides, giving the Americans a slight advantage. Back on the ground, Foley and his squad seek shelter from the disabled aircraft that are now literally falling from the sky, and proceed to the White House. There, they receive a transmission informing them that the Air Force is preparing to carpet bomb the entire city to deny the Russians a strong foothold. Foley's squad fight their way to the roof of the White House and set off flares in the nick of time, aborting the air strike. Flares are lit on the rooftops of other landmarks, signifying that the city is still in American hands.[33]

Narrowing down Makarov's hiding place to two separate locations, Task Force 141 decides to split up. Price and Soap travel to an aircraft bone-yard in Afghanistan, while Roach and Ghost raid Makarov's safe house on the Georgian-Russian border. At the safe house, Roach and his team obtain vital intelligence from Makarov's computer and escape with Makarov's men in pursuit. However, when they reach the extraction point Shepherd betrays them, retrieving the intelligence and taking it with him, murdering Roach and Ghost in the process. Price and MacTavish quickly learn of Shepherd's betrayal and escape a battle between Shepherd and Makarov's men with the help of Nikolai. After contacting Makarov and offering to kill Shepherd for him, Makarov reveals Shepherd's location at a mountain base in Afghanistan. Price and MacTavish raid the base in an attempt to take revenge on Shepherd in a suicide mission. During the infiltration, Shepherd tries to escape and a long boat pursuit ensues.

At the climax of the pursuit, Shepherd boards a helicopter, only for Price to disable it by shooting the helicopter's rotor, causing a crash landing. Price and MacTavish tumble over a waterfall in the process. After recovering from the fall, Price and MacTavish engage Shepherd in a fight. Shepherd is eventually killed by a throwing knife, but MacTavish is severely wounded. Price inspects MacTavish's wounds as Nikolai arrives in a helicopter to extract them. Nikolai warns them that they will be pursued, but Price insists that MacTavish receive medical attention; Nikolai mentions that he knows a safe place to go to, and MacTavish and Price are now wanted criminals globally, and go into hiding.

Achievements/Trophies
The game features 51 trophies and 50 achievements worth a total of 1000 gamerscore.

The PS3 exclusive trophy is entitled "Is That All You Got?" and is unlocked after all other Trophies are attained.

Special Ops
A new Special Ops mode includes one and two player cooperative play. Special Ops mode includes several fast-paced action missions similar to "Mile High Club" which are more difficult than normal campaign missions and are not related to the main storyline. It picks out certain parts of the single player campaign that "work well with co-op". Missions are unlocked by earning stars, which are acquired by playing levels at certain difficulties. Regular difficulty earns one star, hardened earns two, and veteran earns three. Missions are divided into five groups, named Alpha, Bravo, Charlie, Delta, and Echo - the last being the hardest. Within the groups there are types of missions such as "Breach and Clear" and "Elimination". There are special enemy types, such as those using riot shields, even the Special Ops exclusive Juggernaut, wearing heavy bomb squad armor. There are a total of 23 Special Ops missions, two of which are only playable in two player co-op due to one player assisting the other in carrying out the mission's objective from air support.

Multiplayer
Multiplayer is similar to the previous two titles on Xbox 360 and PlayStation 3. However, multiplayer on the PC is quite different from previous games. The PC version no longer includes dedicated server support. While previous Call of Duty titles allowed multiplayer matches with up to 64 people and user-made maps and mods, Modern Warfare 2 on PC is almost identical to console versions.

Gameplay
The basic gameplay stays the same from Call of Duty 4 and Call of Duty: World at War. A few changes have been made;


 * The HUD is now much more sleek and easy to read on a smaller TV than the HUD from Call of Duty 4.
 * Blood will now cover the screen when the player is injured. This effect will eventually go away and it is still possible to see through the blood.
 * Create-A-Class, while still unlocked at level 4, has a few changes;
 * There is a new slot called "Equipment" where the player can choose from a Claymore, C4, Throwing Knife and Semtex among others as well as the original Fragmentation Grenade.
 * Secondary Weapons now consist of Shotguns, Machine Pistols, Launchers and Handguns, instead of just pistols in the previous games.
 * Likewise with the HUD the Create-A-Class interface has been re-done from the previous games and is now much more sleek and user-friendly.
 * As with previous games, in addition to player created classes there are five preset classes, but this time they include weapons and equipment unlocked at higher levels rather than just the items that are available by default when CaC is first unlocked.
 * In-game Host Migration has been implemented - if the host of a multiplayer game leaves, the game will automatically pause for a few seconds to choose a new host, and then the game will resume, preventing many highly irritating mid-game ends with no or inaccurate results.
 * Idle sway for the ACOG has been eliminated for all non-sniper rifle weapons.
 * Idle sway for all non-scoped weapons and AK-47s with attachments (apart from ACOG) has also been removed.
 * New perks including BLING which allows you to have 2 attachments on your primary weapon,ninja which allows no footstep sounds, cold blooded which gives you an advantage against UAV,thermal,Air support and turrets. Each of the new perks has a pro which you have to unlock by completing the regular perk.
 * In Split Screen, instead of all Pre-set Classes, users can rank up and create their own.

Ranks
The ranking system works in the same way as the previous two games. As the player plays matches, they will gain XP. Once the player reaches a certain amount of XP, the player will level up. There are now a total of 70 levels in Modern Warfare 2, as opposed to 55 in Call of Duty 4: Modern Warfare and 65 in Call of Duty: World at War. There are also 10 levels of prestige, just like in the other two games. As in World at War, the player can unlock a total of 5 extra custom class slots by the 9th prestige.

New Playlists
There are a few new additions to the playlists.

Former Playlists

 * 3rd Person Team Deathmatch
 * 3rd Person Hardcore Team Deathmatch
 * 3rd Person Cage Match

Cut Playlists

Weapon list
This is a list of all weapons that are featured in Call of Duty: Modern Warfare 2. In multiplayer, the weapon class system has been completely revamped from the version in Call of Duty 4: Modern Warfare.





Weapon attachments
Weapons attachments return in Call of Duty: Modern Warfare 2 with a few changes. Firstly, new attachments were introduced, such as the Thermal Scope and Heartbeat Sensor. Secondly, some weapon attachments are now unlocked through the use of other attachments, such as getting 20 kills looking through the ACOG Scope to unlock the Thermal Scope or 60 kills looking down the RDS to unlock the Holographic Sight. Lastly, the Grip and Grenade Launcher no longer count as a tier one perk. Enemies throughout the campaign will now carry weapons customized with a variety of attachments. When a player goes to pick up a weapon, it will actually tell them what attachments the gun has, except when the gun is using Bling or does not have any attachments.



Perks
Players can choose one perk from each of the three main tiers and one Death Streak perk for a single class loadout. Three kill streaks can also be chosen, but these are not class-specific.

Pro perks are upgraded versions of existing perks that are unlocked by fulfilling certain requirements with the original. All perks have Pro versions and all are unlocked by the Pro IV challenge for that specific perk. Note that Pro V and Pro VI challenges exist. Pro V does not earn anything except a large amount of XP. Certain Pro challenges unlock Emblems or titles for players to use in their Callsigns. Pro perks include the benefits of the original version while adding new benefits. There are less Perks than in Call of Duty 4 due to the addition of Pro Perks, as well as the removal of many less-useful Perks.

Deathstreak rewards
Death Streaks are the opposite of Kill Streaks: these give the player certain rewards for being killed a certain amount of times in a row without getting a kill. Once the Death Streak activates, it remains active until the user gets a kill, no matter how many times the user dies until they get that kill. Once the user gets a kill, the Death Streak will still be active for that life, but will then deactivate upon their next respawn. Only one can be equipped to a class. Unlike Perks, Death Streaks do not have Pro versions.
 * Start - 4 deaths - Copycat: Copies the loadout (Weapons, Perks, and Attachments) of the enemy that killed the player last.
 * Lv. 6 - 3 deaths - Painkiller: Triples health for ten seconds after respawn.
 * Lv. 27 - 4 deaths - Martyrdom: Drops a live grenade when killed.
 * Lv. 39 - 4 deaths - Final Stand: Allows the player to fight on the ground with any weapon. Much like Last Stand, except the player is able to return to their feet if no damage is inflicted.

Killstreak rewards
Players can select three Killstreak Rewards at a time. A player's killstreak loadout cannot be changed from class to class; instead, one loadout will be used for all classes. Killstreaks now stack (getting a higher killstreak no longer gets rid of the lower unused one, but it will not be available until after the current killstreak is used).
 * 3 - UAV: Deploys a UAV to scan the map and reveal enemy locations. Now able to be shot down.
 * 4 - Care Package: "Air drop a random killstreak or ammo". Deploys by throwing a red smoke grenade obtained after getting a 4 killstreak. The care package can be picked up by anyone once it hits the ground, including the enemy team. The Care Package can also kill, if it lands on a player. The package can contain any killstreak, excluding the nuke, Emergency Airdrop, and of course, another Care Package.
 * 4 - Counter-UAV: Blocks an enemy UAV and disables their radar for the duration. This can also be shot down.
 * 5 - Sentry Gun: Allows the player to deploy an automated M5 Minigun Turret, which is dropped in an air-drop. The gun automatically fires at enemies in its line of sight, but it can be destroyed by enemy fire. Once deployed, the player who placed it can pick it back up and redeploy it somewhere else.
 * 5 - Predator Missile: Fires one controllable missile at a designated target area. User is vulnerable during use.
 * 6 - Precision Airstrike: Initiates an airstrike on a targeted area much like the Airstrike in Call of Duty 4. However, the user can now control the direction the airstrike comes from.
 * 7 - Harrier Strike: Deploys a small airstrike followed by a hovering harrier that will attack enemy players for a short time.
 * 7 - Attack Helicopter: Deploys a Hind (for Spetsnaz, Militia and OpFor teams) or a Cobra (for Task Force 141, Rangers and Navy Seal teams) armed with one minigun to attack enemy players.
 * 8 - Emergency Airdrop: Deploys a C-130 that drops four care packages. Unlike the care package, it is impossible for the player to receive an EMP from one of the packages.
 * 9 - Pave Low: Deploys a Sikorsky MH-53 armed with two gun turrets.The Pave Low also has one flare defense against guided missiles.
 * 9 - Stealth Bomber: Deploys a B2 Spirit that is invisible on the enemies radar. The bomber drops a large carpet bomb. Just like the Precision Airstrike, the user can control which direction the bomber comes from.
 * 11 - Chopper Gunner: Deploys a AH-64 Apache (for Task Force 141, Army Rangers, and SEALs) or a Mi-28 Havoc (for Spetsnaz, Militia, and OpFor) attack helicopters that the player controls. User is vulnerable during use. The Chopper Gunner has one flare to defend against guided missiles.
 * 11 - AC-130: Deploys an AC-130 gunship that the player controls. User is vulnerable during use. The AC-130 has 2 flare defenses against guided missiles.
 * 15 - EMP: Deploys an Electromagnetic pulse that destroys enemy killstreaks and disables the enemies' HUD, radar and any other device that uses electronics (various attachments, C4, Claymores, Semtex, etc.) Enemies also cannot use any of their killstreaks while the EMP is active. The EMP also give the enemy's screens a bit of a grainy look to it.
 * 25 - Tactical Nuke: Calls in a nuclear weapon that detonates after 10 seconds, killing every player in the match and ending it in favor of the bomb user's team.

Accolades
Accolades are awards earned in game and given after a match. They do not reward XP.

Callsigns
Callsigns are multiplayer name-tags that appear on screen when a player achieves a kill, secures a command post, and other things. The callsign includes the Emblem, Title and name of the player.



Challenges
Challenges remain largely unchanged from the previous game. However, on the event of prestiging, a tier of challenges will be unlocked, under the title of Prestige. These challenges mostly require the player to get a certain amount of kills using a killstreak etc.

Local split-screen
Call of Duty: Modern Warfare 2 also features local split-screen on a single console, similarly to previous installments of Call of Duty. Up to four players can play on a single console. Local split-screen features all of the same game modes and custom settings as online private matches, and for the first time allows players to unlock things and customize their classes just like in the online modes. One of the offline multiplayer settings enables players to play with everything that they have unlocked online, but playing offline will not earn them XP for their online account, nor will anything they do offline affect any of their online leaderboard stats.

Updates
The Latest update added the Resurgence map package DLC, which added the Resurgence playlists and Barebones playlists.

Title
Due to the commercial success of Call of Duty 4: Modern Warfare, Infinity Ward thought that the modern setting had entered unto a "world of its own," they then dropped the prefix from the title. Activision was reportedly getting "bored" with the series, and so ran with the idea. It was later found from surveys that there was a 40% drop in brand awareness after the removal of the "Call of Duty" prefix. At E3 2009 the customer intent to buy the game had dropped significantly because of the title change. It is speculated that Activision chose to bring the Call of Duty prefix back in response to these surveys in order to prevent confusion with consumers. The Call of Duty prefix is still absent from the Hardened and Prestige editions, as well as in-game menus.

Peripherals
On July 21, 2009, Infinity Ward's Community Manager Robert Bowling revealed through Twitter that a Call of Duty: Modern Warfare 2 controller was in the works, but initially withheld the name of the manufacturer. It was revealed on August 11, 2009 that peripherals manufacturer Mad Catz was contracted by Activision to create a line of Call of Duty: Modern Warfare 2 controllers and accessories for all platforms that the game will be released on.

On August 24, 2009, Mad Catz revealed their Call of Duty: Modern Warfare 2 lineup including Combat Controllers for Xbox 360 and PS3 platforms, a Throat Communicator for Xbox 360, and a Headset for PS3. For PC there is a Combat Gamepad, "Sniper" Mouse with 2 stage weighting system, and Combat Keyboard. The Xbox 360 and PS3 controllers feature programmable combat buttons. The accessories come in black and snow digital camouflage. There is also going to be Call of Duty: Modern Warfare 2 Skins and Faceplates if the player does not wish to buy the Mad Catz gear, which snap onto the controller and console rather than being a vinyl skin. The accessories launched along side the game.

Sequel
Call of Duty: Modern Warfare 3 was confirmed to be in pre-production on April 9, 2010 and is set to be released sometime in 2011.

Trivia

 * Call of Duty: Modern Warfare 2 is the first Call of Duty sequel that actually refers back to a previous game. All other games in the series have focused on different battles or events.
 * Like Call of Duty 4: Modern Warfare, there are no openly controllable vehicles in adversarial multiplayer modes; the only controllable vehicles are the AC-130 and the AH-64 Apache/Mi-28 Havoc (Chopper Gunner), and the user can only control the gun positions after a killstreak of 11.
 * Inside the art book, there is a picture of a person on a motorcycle, indicating an early concept for a chase scene that never made it into the game.
 * This is the first game in the Call of Duty series where Light Machine Guns and Shotguns can have silencers.
 * Monster Energy has released Modern Warfare 2 themed cans.Monster mw.jpg
 * This is the first game in the series to feature more than two editions rather than just Standard and Collector's.
 * In various multiplayer maps, there are newspaper dispensers and postcards lying everywhere. The newspapers' lead article is Call of Duty 2. The newspapers' name is the Infinite Ward Times. The postcards that fly and land can be read with a sniper rifle. Infinity Ward's logo can be seen on them, along with a (really hard to read) code, the only few that can be read are 'X', '6', and '9'.
 * Infinity Ward has stated that they will look into an online stat system for its website as a potential addition later on.
 * There are many Infinity Ward references in their multiplayer maps.

 * This game was seen in the movie, "Percy Jackson & The Olympians, The Lighting Thief". It was seen being played by Luke; he was with the Militia playing Team Deathmatch in Favela with an M16A4 Bling with Red Dot Sight and a Grenade Launcher.

 * The game was featured in Family Guy in the episode "April in Quahog" where Peter Griffin is seen playing Team Deathmatch on Favela as Task Force 141 whilst also struggling to control the Xbox 360.
