The four-mission Co-op Story charts the assignments of special agents Archer and Kestrel, two spies involuntarily placed on the same team when four Russian EMP devices are stolen. The EMP devices in question are related to the main plot of Sam Fisher's mission, making this game mode a prequel of sorts. Archer and Kestrel must travel deep into the Russian underworld to track down the EMP devices before they are sold to the highest bidders among the lowest people.
