The United States has a military presence in two-thirds of countries around the world & some of them have had enough. A group of terrorists calling themselves The Engineers have had enough & initiate a terror ultimatum called the Blacklist
- a deadly countdown of escalating attacks on U.S. interests. Special operative Sam Fisher is now the leader of the newly formed 4th Echelon: a clandestine unit that answers solely to the President of the United States. Together they must hunt down The Engineers by any means necessary & stop the Blacklist countdown before it reaches zero.
