Duke Nukem 64

Duke Nukem 64 is a port of 3D Realms PC game, Duke Nukem 3D. The game brought the iconic series to the Nintendo 64 for the first time.

However the port brought through several changes of its own. First off the game was censored, this led to removal of some in-game music and the renaming of many in game items to remove any drug and sex references.

Additionally the port saw the merger of the expansion pack for the original PC game in with the base game.

This meant that levels were modified to include content that was not originally present. It also saw a change in the way the levels were played out, becoming sequential rather than episodic.

The final major change was the final boss being turned into a full 3D model. Ultimately Duke Nukem 3D as a whole was a huge success, selling over 3.5 million copies, though its hard to tell how much of these were contributed by the Nintendo 64’s version,
