Pickle released an engine port, which can be used to play Wolfenstein 3D.
Because Wolfenstein 3D is showing swastika’s during ingame, we can not provide any links as it would be against german law. In particular it would be against paragraph 86 StGB “Verbreiten von Propagandamitteln verfassungswidriger Organisationen”.
Allthough this is just an engine port of Wolfenstein 3D, the game itself is still indexed.
