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 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. 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.

Gameplay
Although Modern Warfare 2 runs on a different game engine, the gameplay is similar to the previous two games, similar enough for players of these two games to feel right at home. There are a few new additions to gameplay, mainly in multiplayer, which will be covered later in the article. See Infinity Ward Game Engine Mechanics for more information.

Single player
Call of Duty: Modern Warfare 2 continues five years after the events of Call of Duty 4: Modern Warfare.

Plot overview
"This is for the record."

- Captain Price

Call of Duty: Modern Warfare 2 is set five years after the conclusion of Call of Duty 4: Modern Warfare. Despite the efforts of the Marines and the SAS, the Ultranationalists seize control of Russia and enshrine Imran Zakhaev, the deceased leader of the Ultranationalists, a hero and martyr. Meanwhile, Vladimir Makarov, one of Zakhaev's former lieutenants, begins a reign of terror against Europe by staging numerous terror attacks. The game follows two major factions. One of those is Task Force 141, a multinational military force assigned with eliminating Makarov and the Ultranationalists. The other is the U.S. Army Rangers, who fight in Afghanistan and then, following a Russian invasion of the United States, in the area surrounding Washington D.C. Traitors are revealed in the U.S. forces and protagonists are named as war criminals. The game culminates with Captains "Soap" MacTavish and John Price going into hiding after being betrayed by Lt.

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 basically crap disguised as urine 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 a fat man crapping himself

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.
 * 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.

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
 * Cage Match
 * Mosh Pit

Cut Playlists

 * Global Thermonuclear War
 * One Flag
 * Arena
 * Die Hard

 * 3rd Person Free For All

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 specificperk. 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 Packages.
 * 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 an AC-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.
 * 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.
 * 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

 * Main article: Call of Duty: Modern Warfare 2 Accolades

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

Callsigns

 * Main article: Callsigns

Callsigns are multiplayer name-tags that appear on screen when a player achieves a kill, secures a command post, and other things.

Challenges

 * Main article: Call of Duty: Modern Warfare 2 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
Latest update, Resurgence map package DLC which added the Resurgence playlists and Barebones playlists.

That is all that is known at the moment.

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.

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 Mw2 Can.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'.
