In Tom Clancy’s Splinter Cell Blacklist, veteran operative Sam Fisher returns as the leader of Fourth Echelon, a newly formed, elite clandestine unit answerable solely to the President of the United States. Following a devastating terrorist attack on an American military base, a rogue faction known as "The Engineers" issues a terrifying ultimatum: the Blacklist, a deadly countdown of escalating terrorist strikes against U.S. interests unless all American troops are withdrawn from foreign soil. Operating from the Paladin, a high-tech airborne command center, Sam and his specialized team must race against the clock across the globe, utilizing cutting-edge espionage tech and brutal combat tactics to hunt down the architects of the plot. As the stakes escalate and political tensions reach a boiling point, Fisher is forced to blur the lines between national security and personal morality to neutralize the threat before the final countdown reaches zero.
