Story: The Mission Pack begins with a cutscene showing a wounded Agent 67 wandering through a dark hotel corridor and arriving at his room. Upon entering, he collapses and begins to have flashbacks regarding previous assassinations he committed, beginning with the aftermath of killing Ivan*s Dad: Alexander Grovchenko at the end of the First The Assasin Codename 67.This mission pack is not to mention the presence of rain or snow in every level and peculiar, unnatural events occurring in some levels. In the game, 67 visits several locations, including Romania, Kamchatka, the United Kingdom, Rotterdam, Budapest, Hong Kong, and finally Paris.

While 67 suffers, a doctor sent by the Agency arrives unexpectedly and treats 67, then flees when he discovers GIGN officers surrounding the hotel. At the end of the game, 67 regains consciousness in the hotel room with an expired mission briefing. It is revealed that 67 was hired to kill a US ambassador, Richard Delahunt, and a famous tenor at an opera house in Paris, but was also tasked to kill their mutual friend, Inspector Albert Fournier who has sent a team of police to capture 67 after discovering his hideout.

67 discovers the situation he is in and moves on to kill the inspector and escape the area. He then makes his way to the airport, where he boards a plane and escapes the country. His contact, Diana, reaches him on the plane and suggests that his target may have been tipped off.
