Tom Clancy's Splinter Cell: Blacklist

The game starts with Sam Fisher and his old friend Victor Coste who are about to depart from Andersen Air Force Base in Guam when an unknown enemy force destroys the entire base. Assisted by hacker specialist Charlie Cole, Sam and Vic manage to escape, although Vic is severely injured from protecting Sam from a grenade. Soon after, a terrorist organization calling itself "The Engineers" claims responsibility for the attack and announces that this attack is the first of a deadly countdown of escalating attacks on United States assets which they call "The Blacklist." They declare that they will halt the attacks only after the U.S. Government recalls all American troops deployed abroad.

In response, President of the United States Patricia Caldwell, who had just shut down the corrupt Third Echelon, assigns Fisher, Charlie Cole, Isaac Briggs and Anna 'Grim' Grímsdóttir to a newly created special operations and counter-terrorism unit called "Fourth Echelon." She installs Sam as the commander and charges the unit with the task of hunting down The Engineers and stopping them. Fourth Echelon's base of operations is a customizable cargo plane, codenamed "Paladin."

Sam and his new team's first course of action is to capture Andriy Kobin from a CIA safe house in Benghazi, Libya and obtain information from which they can learn more about The Engineers' plans. Sam successfully extracts Kobin and arrests him, keeping him aboard the Paladin. Kobin reveals some information about his business associates in Mirawa, Iraq. Infiltrating an insurgent stronghold there, Sam learns that the Blacklist attacks are more serious than originally thought. Sam arrives at a death chamber to find an executed US soldier whose execution was taped. The executioner was Majid Sadiq (Carlo Rota),[7] a terrorist and former MI6 agent. In the video, Sadiq directly tells Sam to stop intervening or suffer the consequences.

Intelligence from Mirawa points to the next Blacklist attack being in Dallas, Texas. Sam asserts to Fourth Echelon that a direct attack would be too simple and that the true target is another city. Charlie notes that the TSA list of "do not fly" citizens was offline for roughly six hours with a group of men traveling through Chicago's O'Hare International Airport during the time the list was offline. The target is a water filtration plant off Navy Pier, which is scheduled to release a hazardous biological agent into the water supply of Chicago. Sam stops the devices and shuts off the outflow valve, sparing Chicago.

Kobin reveals to Sam back on the Paladin intelligence about one of his associates, a dealer named Reza Nouri who supplies mercenaries for hire. Sam assaults his mansion in Ciudad del Este, Paraguay and interrogates Nouri. Nouri states that to whom he lends his men is none of Sam's business. During the interrogation, Nouri's mansion comes under attack from suspected operators of Quds Force. Nouri agrees to give up Sadiq in exchange for a safe extraction.

Grim and Charlie gain intelligence about a sleeper cell of The Engineers in London, England. The cell has been activated and Sam infiltrates an abandoned mill to gain intelligence on The Engineers' next plans. Sam finds shipping documents from Iran, confirming the suspicion that Iran and Quds Force were involved in the Blacklist attacks. With the last of the chemical bombs about to leave the shipping bay, Sam sneaks onto the truck and places a GPS tracking device inside the bomb. Sam is exposed to near lethal amounts of the chemical agent and, while trying to exfiltrate, is captured alive by Sadiq. Briggs, who was providing sniper overwatch, is forced to rescue Sam, but lets Sadiq escape.

After healing from the exposure to the chemical weapons, Sam infiltrates the former US embassy in Tehran, Iran, which has been transformed into a Quds Force headquarters. Sam installs a flash drive on a mainframe computer given to him by Charlie, which is programmed to search and rip anythin
