cich: Not fixed.
I mean it's moddable, but too much hassle for modders to port old stuff to the new one.
And the amount of censorship in the old titles is minuscule. I'm no purist, I can live without the swastikas and the red cross.
trusteft: There are no swastikas in the Doom series. Censored or not. Also, you have something against the Red Cross? It helps millions of people around the world.
The various nazi stuff is in a secret level in Doom 2 based around Wolfenstein 3D, the swastikas were in Doom 1 secret based around Wolf3D too. They removed them in BFG edition. The same happened to the red crosses on Medpaks and Berserk items. Apparently Red Cross didn't like red crosses being in Doom, and Bethesda agreed to remove them.

As I said, lack of these things is barely noticeable when playing olden Dooms.
