I WORKED A LONG TIME ON THIS SO I HOPE IT HELPED
PLEASE REP THANKS

Gameplay

A special Spec-Ops mode will take the place of co-op campaign but will feature a whole new set of missions and objectives and only allows 2 players.

NPCs will carry customized weaponry, similar to custom classes made by players in multiplayer. A number of combinations were seen in the '09 E3 Demo, including AK-47s with ACOG Scope and FAMAS with Red Dot Sight. In addition, a different melee stance will be introduced, which involves holding a pistol with the combat knife out, supposedly allowing for faster knife attacks. Also, throwing knives will be usable in multiplayer in place of grenades. It is currently unknown as to whether or not they will be usable in singleplayer.
Gameplay in a Special Ops mission

Hostage situations will play a role in the game, but it is unknown as to whether these situations will be part of gameplay or cutscenes.

UAV will return as a killstreak. New killstreaks will be an Airdrop for four kills, a Predator Missile for five kills, and an AC-130 for eleven kills. There is also a feature to customize your killstreak reward.

Players will be able to dual wield side arms. In multi-player a new perk Akimbo will make this possible, and in single-player sets of two side arms can be picked up from the ground.

Perks will be able to receive upgrades that increase their effectiveness. They are upgraded through constant use of the perk. E.g., if using sleight of hand consistently, you r upgrade would be able to look down the sights of your gun faster.

Objective way-points will now be marked on the screen itself, along with distance from the way-point in meters.


Game modes

* Free-For-All
* Capture The Flag
* Team Deathmatch
* Search and Destroy
* Domination
* Demolition

Special Ops

A new Special Ops mode will include two-player cooperative play. Special Ops mode will include several fast-paced action missions similar to Mile High Club which will be more difficult than normal campaign missions and will not be related to the main storyline. It will supposedly pick 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 will be divided by groups, called Alpha, Bravo, Charlie, Delta, and Echo, the last said to be the hardest. Within the groups there are types of missions such as "Breach and Clear" and "Elimination". There will even be special enemy types, such as those using riot shields, or even Special Ops exclusive "Juggernauts" wearing heavy armor.
Story
Characters

* Sergeant Gary "Roach" Sanderson will be a playable character.
* Captain "Soap" MacTavish (a playable character from Call of Duty 4: Modern Warfare) will return as a non-playable character. He has a mohawk and a model of his head will be sold with the prestige edition.
* Vladimir Makarov will be the new leader of the Ultranationalists and the main villain of the game, following the footsteps of Imran Zakhaev. His image is previously unknown.
* Major Petrov is the airfield commander in the level Cliffhanger and was probably killed as Roach and Soap eliminate all the enimies at the hangar unless he wasn't in your line of sight.
* "Ghost" will be a character part of Task Force 141 and will also be included in the Modern Warfare 2: Ghost six part comic series. He wears red ski goggles/sunglasses and a skull balaclava.
* Royce is a character seen in the Rio de Janiero video. Not much is known about him at the moment, but he is probably a member of Task Force 141. Judging by his accent, he is American.
* Rojas is an arms dealer located in Rio De Janiero. He wears a brown T shirt and 3 quarter pants. He is seen in the Worldwide trailer.
* "Meat" is a character briefly seen and heard in the Rio De Janiero video. At about 0:45 in the video you can hear one of your squadmates say "Meat, get these civvies out of here", at which point Meat begins yelling at them in Portuguese. Very little else is known about him. When he says "Roger that" it seems his accent is American. He may be the man who wears a helmet.
* Unidentified American member of Task Force 141 is a character in Task Force 141 and seen in the Worldwide trailer rappeling up a helicopter from a castle. He is big and has a shaven head. The trailer proves he is American because he has an American flag on his arm.
* Faust is a character who is an associate of Rojas seen in the Rio De Janiero level. He is shot in the leg by Roach.
* There will be a character who will be a part of the US Army Rangers. The character's voice actor has confirmed he will be Roach's trainer in the prologue.

Plot

Russia is in political turmoil once again. Vladimir Makarov, a brutal leader and former associate of Imran Zakhaev, has set in motion a series of events that will threaten global security. After a series of vicious terrorist attacks, the situation is deemed dangerous enough for Task Force 141, led by Captain Soap MacTavish, to be deployed to Russia and Kazakhstan. There, the force must fight its way through near white-out conditions to infiltrate a secret military base hidden in the mountains. After detonating a large volume of explosives, the team loses the pursuit on snowmobiles. Task Force 141 is later deployed to Rio De Janeiro to capture an arms dealer linked to the plot by ballistics data (who is shot in the leg by Roach and left with Soap and another TF141 member, probably for interrogation), eventually being led to the barren lands of Afghanistan. But the intel Task Force 141 is receiving is likely inaccurate, as even they do not understand the danger of Makarov's sinister plot.
Factions

* Task Force 141
* US Army Rangers
* Federal Security Service/Loyalists
* Ultranationalists/Spetznaz

Single-Player Levels

* Cliffhanger- In this level you are in control of Sgt. Gary "Roach" Sanderson where you start off on a cliff with Cpt. "Soap" Mactavish and begin to climb up the cliff. Soon you reach the base after planting a charge on the fuel station. Then Major Petrov tells Soap and Roach that they have 5 seconds to surrender. Soap tells Roach to go to Plan B. Suddenly Roach blows up the station and kills all the soldiers. They then advance and see a Russian jet explode and slide down a slope and take out Russians on snowmobiles. They then take 2 snowmobiles and escape.
* Slums- Engage in a running firefight throughout Rio de Janeiro to capture an arms dealer named Rojas.
* There will be a level where Task Force 141 assaults a castle, probably in Russia, Siberia or another icy region of the world.
* On E3 2009 Build some Press members saw a level named "International Space Station" But Robert Bowling didn't want to show this level (When Press members asked him to show this level he said "Ah you saw this..." and played Takedown). This appears that we will play in an space station.
* Desert- In this level you will be in Afghanistan and fight underground.

Locations

* Rio De Janiero, Brazil
* Afghanistan
* Russian Airport
* Soviet Gulag
* Tian Mountain Range in Kazakhstan

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.
