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
In the German version of the game, it avoids making direct reference to Nazi Party and the "Third Reich", in order to comply with strict laws in Germany. The player is not battling Nazis but a secret sect called the "Wolves" led by Heinrich Höller, whose name is a pun of the original character Himmler (Himmler roughly translates as ""Heaven"er", Höller as ""Hell"er"). The Nazi swastika is also not present: the German forces use a Wolfenstein logo which is a combination of a stylized double-headed eagle prominent in most Nazi symbolism, a "W" (standing for Wolfenstein), and the "Quake III: Team Arena" "QIII" logo (the game engine and network code that "Return to Castle Wolfenstein" is based upon). The "W" eagle logo is prominently seen on the cover art for the American version.
