Averted. Incredibly, given Australia's reputation, Duke Nukem Forever arrived on Australian shores completely uncensored and unabridged.
The game itself wasn't banned in the UK, but they had to change the cover art due to it being illegal to publicly depict smoking in the country. As a result, Duke's cigar was deleted, and his expression changed to a vaguely annoyed look.
Jon St. John reprises his role as Duke in English.
Fumihiko Tachiki provides Duke's Japanese voice for the first time ever in the story of the franchise. This is also considered as Hilarious in Hindsight, since his most famous role was voicing Gendo Ikari, and unlike Duke, not only he wants his girl back, he will bring the end of the world along with her!
Limited Special Collector's Ultimate Edition: BEHOLD!◊ The Duke Nukem Forever Balls of Steel Edition! Comes with a bust of Duke himself, an artbook with art through the ages, a limited edition comic book, and other such novelties! All for the heart attack causingly low price of $99.99!

No Export for You: Zig-Zagging Trope, the Russian version of the game is a separate Steam entity. Meaning: it is locked out of Steam's usual language-selection options, as well as ANY patches and DLC, both Existing and future, because the localization company and 2K Games cannot settle about whose responsibility it is to adapt them for the locked-down Russian-only release. All the appropriate access and unlock codes are provided, they are simply not compatible with the Russian version.
Pigeonholed Voice Actor: Jon St. John is reprising, once again, his long-standing role as The Duke himself.
Promoted Fanboy: Randy Pitchford, who worked on Duke Nukem 3 D as a junior developer, states he was (and is) Duke Nukem's biggest fan, and made sure that 3D Realms' game wouldn't die.
Talking to Himself: Near the beginning of the game Duke gets into a brief argument with an obnoxious tourist sitting on his throne. The obnoxious tourist is also played by Jon St. John, apparently. It seems the guy has a pretty impressive vocal range.
Forever started as a sidescrolling platform game based on the engine of Alien Rampage and the sprites of Duke Nukem 3 D. Said project was scrapped, and the title was used to the sequel to Duke Nukem 3 D. An unrelated sidescrolling shooter titled Duke Nukem Manhattan Project, based on the Prism 3 D engine, was relesed in 2002.
Start with the fact that the game we got only ever got finished because many of the levels were shortened, merged, or just cut out and work from there.
Many of the characters, weapons and setpieces seen in the early trailers were not used for the final version. An Action GirlDistaff Counterpart of Duke (Bombshell) and a character named "The Prospector" were both absent from the final game (and were likely cut long before Gearbox got their hands on the game).
Ben "Yahtzee" Croshaw of Zero Punctuation was asked to write the script at one point. Most of the development team absolutely loved his outcast, but George Broussard was more sceptical and kept asking "Would Duke really do/say this?", and eventually it was turned down. According to Yahtzee it portrayed Duke as an ironic character and made fun of everyone around him, as he believed it would be the best way to reintroduce Duke Nukem to a modern audience. It got scrapped in favor of "Duke played straight in a silly world" that we see now. Yahtzee was given a chance to revise the script to go with this tone, but he declined because that didn't make any sense to him.
