This is a stealth action game in which players assume the role of a British assassin who engages in missions of sabotage against German forces during World War II. Players navigate through enemy bunkers and strongholds, disrupt Nazi activities, and assassinate enemy soldiers in a variety of ways: players shoot soldiers, slash their throats, bash their skulls, and stab them in the eye or from behind. Blood gushes out when enemies are killed, and slow-motion effects and gurgling sounds can sometimes be heard. During the course of the game, players can collect morphine syringes to enter a performance-enhanced, dreamlike state (i.e., "Morphine Mode"). The drug allows players to get to enemies before they can notice. Some German profanity appears subtitled in English (e.g., "f*cking," "sh*t," and "a*shole").
