Splinter cell Co-Op

 

Line of Story Splinter cell coop :
Ten days prior to the apprehension of Sam Fisher, Third Echelon agent Archer and Voron agent Kestrel are deployed to Nevsky Prospekt in St. Petersburg, Russia to halt rogue elements of the Russian military from selling advanced warheads on the black market. Intelligence from Andriy Kobin has pointed Archer and Kestrel to drug and human trafficker Valentin Lesovsky as the broker for the sale. Archer and Kestrel are to terminate Lesovsky and his associate, Boris Sychev, as well as gaining Lesovsky's contact list.
Archer and Kestrel are later deployed to the Russian embassy in Baku, Azerbaijan to gather intelligence on an arms deal conducted by former Russian GRU colonel Leonid Bhykov. Archer and Kestrel observe the arms deal and learn that Bhykov betrays Tagizade and orders his men to kill Tagizade. Archer and Kestrel prevent the destruction of the weapons crates, learning that the weapons Bhykov was going to sell were Block II JDAM missile guidance kits. Archer and Kestrel make their way to the banquet area to interrogate Bhykov. Archer and Kestrel learn that Bhykov was working with Major General Kerzakov, and that Kerzakov was in the Yastreb Complex, an underground fortress situated underneath Moscow's Red Square.
Archer and Kestrel infiltrate the complex to avert the sale of the JDAM kits to the Iranians and learn the location of the warheads, which Archer and Kestrel discovered were EMPs. They render the JDAM kits inoperable by using their portable EMP devices, and download data from multiple servers to trace the EMP devices to the Mozdok Proving Grounds, killing Kerzakov in the process.
Sneaking aboard a supply truck, Archer and Kestrel infiltrate the Mozdok Proving Grounds in North Ossetia. They manage to secure the EMP devices with the help of Kobin. However, during the middle of extraction via transport plane, Tom Reed contacts Archer on his earpiece and orders him to kill Kestrel. Kestrel however learns of the order from reading Archer's OPSAT device, forcing him to act in self-defense. Either Archer or Kestrel can survive, and Kobin then executes the survivor in the next cutscene. Archer and Kestrel's bodies can later be seen in body bags below the chandelier in the first hall in the 'Kobin's mansion' mission in the single player story.

Call of Duty Modern Warfare 3 Story line :

The United States under siege by Russian forces, ultranationalist Vladimir Makarov on the loose, Captain John “Soap” MacTavish and Captain John Price wounded and on the run with the Russian informant known as Nikolai.
Fleeing to a safehouse in Dharmasala, India, the three are attacked by Makarov’s men. In this firefight players take on the role of Yuri, a loyalist who works for Nikolai. Their safehouse compromised, the group flee the area in a helicopter.
The game then cuts to Manhattan where Russia is launching an attack on the city from a fleet of ships parked in the Hudson River. (It appears the famous U.S.S. Intrepid may be destroyed.) The U.S. calls in Delta Force to repel the attack. You take on the role of Frost, a Delta Force operative under the command of Sandman. Your goal is to take out a jamming tower on top of the New York Stock Exchange to open the area for a U.S. counterattack.
Following the mission, Delta flies out of the city on a Blackhawk, gunning down enemy choppers as they make their way to the harbor where they have to infiltrate and take down a Russian sub which is coordinating the attack.
As the New York missions wrap up the game jumps forward in time half a year, thrusting players into the role of a Russian agent tasked with protecting the president of Russia as he flies to sign a peace treaty with the U.S. The plane is attacked by hijackers mid-air who attempt to kidnap the president and his daughter. The daughter manages to escape. The president of Russia in hand, Makarov vows to prevent a peace treaty by getting the launch codes out of the president and launching an attack against the U.S.
The game then returns us to Price, Soap and Yuri, now in Africa in a search for Makarov. They meet with a local South African arms dealer who tells them about a shipment of chemical weapons that Makarov is trying to buy. The group make their way to Sierra Leone to secure the weapons from African militia.
Next, players take on the role of an SAS operative who is tasked with stopping a delivery of weapons of mass destruction at a London dockyard. A gun battle ensues, and the agents are chased through the London subway. The mission culminates with a series of unmarked trucks exploding in front of the house of Parliament, releasing a deadly chemical agent.
Price discovers that the South African arms dealer who tipped them off about the chemical weapons deceived them and travels to Somalia to find the man and interrogate him. Through the arms dealer, Price discovers that Makarov’s right hand man, Volk, is hiding out in Paris.
The game’s attention next shifts to Hamburg, Germany where players take on the role of a U.S. tank gunner fighting to push back a Russian advance backed by armored divisions.
As Hamburg falls, the game shifts us back to the story of Price and his crew. Now in Paris, players control Delta Force operative Frost who, with the help of the French special forces, leads an assault on Volk’s location in the underground catacombs of the city. Next, players take to the sky supporting Frost’s ground movements as a gunner in an AC-130.
After capturing and interrogating Volk, Frost learns that Makarov has a meeting in a Prague hotel. Players control Yuri as he and Soap slip into the Russian-controlled city and set-up an ambush for Makarov in a church bell tower. Makarov somehow catches wind of the trap and escapes. Soap, Yuri and Price then have to fight their way out of the city.
Yuri leads the team to one of Makarov’s headquarters in the Czech mountains and the group infiltrates the location, looking for clues. They discover that the ultranationlist has the president and is trying to get the codes out of him. Makarov has also discovered the location of the Russian president’s daughter. The group move out to Berlin to try and prevent her kidnapping. Playing as Frost, gamers must find the daughter and protect her, while making their way through war-torn Berlin. The daughter, however, is captured and flown away.
Frost next makes his way to the Kremlin where a task force of operatives attack and free the hostages, but Makarov manages to escape again.
The game’s final mission occurs in Dubai, where Yuri, Price and Sandman launch an assault on a heavily guarded hotel, eventually finding Makarov and, yes, finally killing him.
