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.
