Reddit player LongJon SiIver found new clues about Return to German Headquarters: Enemy Zone on SteamDB, and screenshots show that the game has been labeled restricted in Steam Germany, meaning it may be banned in the future.
Return to German Headquarters is a well-known open source multiplayer shooter series, Return to German Headquarters: Enemy Zone was released in 2003, and the server still has a lot of players. Return to German Headquarters: Enemy Zone was originally created as a return to German headquarters DLC and was later released as a multiplayer game. The game also had plans to add a single-player mode, but it was shelved due to development problems.
It is reported that the newly labeled "Return to German Headquarters: Enemy Zone" may be banned in Germany in the future, but at the time of writing, the Steam page of the work can still be accessed normally.
Returning to German headquarters is associated with keywords such as World War II, German troops, and Nazism, and the ban in Germany is a matter of course. Germany has the famous Nazi Censorship Law, which was passed in the years after World War II, prohibiting the dissemination and sharing of Nazi images, including Nazi symbols and uniforms, and banning related hate speech. The bill sought to shed germany's image of the past and recover from hitler and the Nazi Party's reign of terror.
In response to censorship, the 2014 edition of Wehrmacht Headquarters: New Order removed the game's swastika and Hitler's moustache before it was released. In recent years, the law has changed, and the new series of works are directly released without deletion. But for some reason, this time I started a game from 20 years ago, "Return to German Headquarters: Enemy Zone".
