Like it's predecessors, the game was heavily censored for the release in Germany. Next to the violence and gore, any reference to Nazi Germany was removed. Additionally, the main enemies were renamed to "Wölfe" or "Sekte der Wölfe" (Wolves; Sect of the Wolves) while flags, uniforms and decorations were modified to bear the Wolfenstein logo instead of a swastika. However, despite the elaborate censorship, on the game itself and on the packaging, a small swastika was missed out on a poster found in the game. Because of that, stores were forced to pull the game from their shelves, and both the uncensored and the censored version of the game were utimately banned.
The game uses an improved id Tech 4 engine, which added significant graphical updates, and uses Havok to render physics properly
For unknown reasons, after Bethesda bought the rights to the Wolfenstein franchise from Activision, this game was removed from all digital distribution sites, not long after Wolfenstein: The New Order was released in 2014. Allegedly, this is because Bethesda have a very negative opinion on Wolfenstein (2009), especially since, in one interview, a Bethesda staff member said he thought "Activision did a crap job" on the game.
In the game, it is clear that Hans Groose have never met Blazkowicz
