The mission begins with Nate, Sully, and Charlie sneaking into an underground passageway in London. They intend to get past the station to a secret library and get out, but they are soon discovered and a gunfight ensues. After clearing out the station, the players proceed to the library and grab a page out of a book that will tell the location of a monastery. The monastery apparently holds a clue as to where the other half of the statue is. However, enemies burst in and cloud the room with smoke bombs. The players must defeat the enemies and retreat out the back. After opening a large door, the heroes find themselves on the train tracks. After pushing a train car out of the way and exiting the station, they are pinned down at a city street by more enemies, including a hammer kickback enemy. Once the players finally defeat the soldiers, Chloe appears with a getaway van, thus ending the mission.
