Wolfenstein
The "Wolfenstein" series of video games started with the 1981 stealth-adventure video game "Castle Wolfenstein". It was developed by American programmer Silas Warner, a pioneer in the early eras of video gaming, especially the stealth genre. It was published by his (then) company M.U.S.E. Inc. (Muse Software). The player controls an unnamed American prisoner of war as he steals war files containing information about secret German war plans while avoiding or sometimes killing guards, and tries to escape the fortified Nazi stronghold Castle Wolfenstein, set during World War II. The game is often credited as one of the first video games of the stealth genre, since it focuses more on avoiding or disarming enemies, and killing them is considered a last resort.
Return to Castle Wolfenstein
After studying the documents captured by Blazkowicz, the OSA has become aware of a scheme codenamed 'Operation: Resurrection', a plan to resurrect Heinrich I, a legendary and powerful Saxon warlock-king from 943 AD. Despite the skepticism of senior Allied commanders, the OSA parachutes Blazkowicz back near Castle Wolfenstein, at the Bramburg Dam, where he fights his way until he arrives at the village town of Paderborn. After assassinating all the senior officers of the SS Paranormal Division present there for the resurrection, Blazkowicz fights his way through Chateau Schufstaffel and into the grounds beyond. After fighting two more "Übersoldaten", Blazkowicz enters an excavation site near Castle Wolfenstein.
