According to your character, Lt. James "Jimmy" Patterson's bio, your character's middle name is "Steven" which is a reference to the game's creator, Steven Spielberg.
By the time you get to the later levels, the Nazis are familiar with your character, Lt. Jimmy Patterson. So much so that when they see you, they will occasionally yell "It's him! It's Patterson!"
Unlike latter FPS games, this game has a 'lone wolf' approach, meaning the player is alone while in missions.
