Released May 05, 1992 Gameplay Shooter Perspective 1st-person Genre Action Setting Sci-Fi / Futuristic, World War II Interface Direct Control ESRB Rating Mature Description Wolfenstein 3D is an episodic first-person shooter and a follow-up to the top-down infiltration game Castle Wolfenstein . The game puts the player in the boots of B.J. Blazkowicz, an allied spy. There are six episodes: the first distributed complete as shareware; the second and the third available after registration; and the three final missions (which happen before the events of the first episode) available in the Nocturnal Missions pack. In the first episode (Escape from Wolfenstein), B.J. is captured, but overpowers a guard with the help of a concealed knife and manages to get out of his cell. Throughout the next nine levels the player guides B.J. searching for an escape from Wolfenstein, guarded by Hans Grosse. After returning to Allied territory, B.J. is given the instructions to Operation: Eisenfaust, where he has to stop Dr. Schabbs and his army of mutant prototypes before they are released into the battlefields. The final mission (Die, Führer, Die!) has a simple goal: infiltrate the bunker under the Reichstag, and terminate Hitler (in a robotic suit) himself. The Nocturnal Missions are focused on the Nazi plans for chemical warfare, and start with Dark Secret, where B.J. hunts for lead researcher Dr. Otto Giftmacher. It's followed by Trail of the Madman, where the goal is capturing the war plans guarded by Gretel Grosse, and the final episode Confrontation, where B.J. meets General Fettgesicht, the planner for the chemical assault. Each episode has nine levels (eight regular and a final boss level), plus a secret level activated by an hidden switch somewhere in the eight first levels. Regular levels...
