The series focuses on the antagonism of the Third Reich. The violent killing of Nazis in the series has been met with controversy, particularly in Germany, where most of the games have been banned and/or censored.
Castle Wolfenstein is a 2D adventure game released in 1981 for the Apple II, written by Silas Warner. One of the pioneers of the stealth game genre, it is a game of avoiding detection and managing limited resources while trying to escape from a Nazi stronghold. Combat was allowed, but bullets were precious, and non-violent options were often safer, such as pulling a gun on a guard and frisking him while his hands were raised. A sequel, Beyond Castle Wolfenstein, was published in 1984.
Wolfenstein 3D, released in 1992, is a re-imagining of the Castle Wolfenstein scenario in first person with an emphasis on direct combat. Stealth and non-violent options are not present. Silas Warner, the designer of the original Apple II games, was not involved in the development. Wolfenstein 3D is important for popularizing the first person shooter and inventing many of the tropes that became standard in the genre.
In an announcement made at the American Film Market (AFM), producer Samuel Hadida and Panorama Media said they've tapped Roger Avary to write and direct Castle Wolfenstein. According to a press release: "Castle Wolfenstein is an action adventure film in the vein of Captain America and Inglourious Basterds. The story follows a young US Army Captain and a British Special Agent on a top secret mission to Castle Wolfenstein, where Hitler will be for the unveiling of a new secret weapon. After reaching the Castle, our heroes are confronted with Himmler’s SS Paranormal Division and must fight, not only for their survival, but for a mission that could alter the course of the War."
