If you want to buy the uncensored version (which has been made available in Germany in 2019), go to this store page!
I will only be discussing the censors and differences of this version compared to the original. If you want to read my review for the uncensored game, check it out here!

So, I finally got around to playing the censored version of this game, which was the only way German buyers (and in some instances Austrian and Swiss buyers as well) were able to play it from its release back in 2015 up until the censorship laws regarding NS-symbols and insignia in videogames were “overhauled” back in August 2018 and the subsequent uncensored release of Wolfenstein: Youngblood in 2019. I don’t actually know how I was able to get both versions of the game, when I bought it, both just showed up in my library. So, sadly, no tips & tricks on how to get this version for yourself.
As for the differences, the most apparent one is the lack of language options. The entire game is in German, both the UI, text, and voice acting which isn’t a huge gripe for me, but I do tend to play games with their original language when it comes to voice acting and only switching to English or German for text/UI. In this instance, however, the German voice acting for both English/American and German characters kinda breaks some of the cutscenes and some things just get “lost” in my opinion. Right in the very first act, B.J. has to infiltrate Castle Wolfenstein with a German disguise but can’t speak the language which obv leads to a risky situation. Now with the German VA B.J. can obviously speak and understand German, so the riskiness is lost. They did try to fix it by saying he’s an atrocious spy with a bad cover, but as soon as you get to some later chapters it just doesn’t make as much sense anymore. All this criticism isn’t to say, the voice acting is bad, it is really good, just what you’d expect from German localization. Another small gripe I have with this are the censors of anything related to the NS-Regime both in text and spoken dialogue. Instead of “Nazis” you have “das Regime” instead of “SS” you have “Spezialeinheit” (=special task force), they’re not bad but just further take you out of the game’s reality.
Now, as for the symbols and insignia, primarily the Swastika and SS-symbol, I gotta admit, after a couple hours I stopped noticing. The Swastika armband was replaced by either the Wolfenstein logo or a symbol which I think is supposed to resemble a wolf, but at first it was hard to tell what it actually was. Those two aren’t necessarily bad, from afar they still portray the same “style”, you kinda know what it’s supposed to be. I mean, what other group in history had a red armband with a white circle and black symbol in it? As long as you don’t look for it or stare at your enemies up close for too long, I can look past it. The SS-symbols however weren’t my cup of tea at all. Instead of the infamous double lightnings you get an upside-down triangle which reminded me more of the Nabla-Operator[en.wikipedia.org] from past quantum mechanics lectures than it did the SS-insignia. I still don’t know the inspiration behind it, or if it has any other meaning, but it just looks weird and nothing like actual insignia a military would use for its ranks.

After all this ranting, my stance on censorships in games hasn’t changed. Censorship in general. I kinda understand what the lawmakers were trying to do here, but it felt oddly targeted as other media of the same time or earlier didn’t receive this kind of in-depth censorship (at the top of my head I can remember the Swastika clearly being portrayed in the Indiana Jones movies, which predate this game). Iirc the reasoning for it was 1) the German criminal code didn’t allow public display of NS-symbols, and 2) they didn’t want games to have those in them out of fear it might portray a pro-NS message (which is stupid in a game all about killing Nazis). I am happy, however, that things have changed recently and actual censorship still happening regards realistic depictions of brutality, but that is a discussion for another day.

Finally, should you buy this version? Resounding NO. It would only make sense to buy this, if you actually speak German and are interested in the differences between this and the uncensored games (which you could also find on YouTube if curious), or if you are an avid collector of games and want to have all Wolfenstein games and regional versions. Apart from that, even though the game itself is good, stay away from this one, especially since the uncensored version is available worldwide without any restrictions.

Achievements
The achievements are the same 50 as in the uncensored game. There is, however, some setting up to do, if you already unlocked achievements in one of the versions. They both seem to use the same save file so already unlocked achievements will be impossible to unlock on the other version. You can bypass this by messing with said save files and forcing Steam Cloud to “save” an empty save. Simply start the game, navigate to the Wolfenstein: The Old Blood folder, delete the save games, close the game and wait for Steam Cloud to update the files. That’s at least how it worked for me. After that you have a blank slate to re-unlock all the achievements!
