International(Uncut) version of Wolfenstein The New Order in Switzerland?

Bethesda Germany is the distributor for Switzerland. This means that, unfortunately, Switzerland is stuck with any censorship that is required by Germany. Technically, this would apply the other way too - if Switzerland required the game to be censored, and Bethesda complied in order to allow distribution, the game would be censored in both Germany and Austria as well.

This is also the reason that the game you get in Switzerland (which is censored) is also dubbed in German (and from what I hear, has no way to change the language to another language).

Edit: Apparently due to protests by players in Switzerland and Austria over the matter, Bethesda has decided to allow distribution/registration of the uncensored version of the game in these two countries. See @DominicDeCoco's answer above for source links. That said, I'm not sure if this means you can buy the uncensored game on Steam's digital store or if you have to buy the game from a different retailer - this will depend on if and when Steam updates their entries.

It is worse than not being able to activate the game. Actually you cannot launch the game even if you activated it while using another country's IP.

So right now the only version to play a proper version of Wolfenstein is to use a VPN* to login to steam using an US IP.

Or, even better, ask for a full refund to show Bethesda that this kind of Geo-lock is unacceptable.

* Using a VPN from another country is against the Steam ToS. I've never heard about people being banned for it - after all, you are not using it to get cheaper prices from antoher country - but you have been warned.
