The story begins in 1944, when Patterson is recruited by the Office of Strategic Services (OSS) to carry out missions aimed at weakening the German war machine. The missions include sabotage of factories, destruction of submarines, intelligence gathering, and prisoner rescue. As the player progresses, they face enemy troops, SS guards, and cutting-edge technologies, with the goal of undermining Nazi plans.

The game stands out for its realistic depiction of war, historical accuracy, and cinematic atmosphere, with music by Michael Giacchino and a design focused on stealth approach and tactics. It was groundbreaking for its time, laying the foundation for the later success of the Medal of Honor series and significantly influencing the war FPS genre.
