Duke Nukem 3D: Atomic Edition is a special edition re-release of Duke Nukem 3D. For customers who already owned Duke Nukem 3D prior to the re-release, the Plutonium PAK was sold as a patch that would upgrade existing versions of Duke Nukem 3D to the Atomic Edition. The "Atomic Edition" and "Plutonium PAK" titles are often used interchangeably.
The Atomic Edition corresponds to versions 1.4 and 1.5 of Duke Nukem 3D, both of which were released in 1996. The Atomic Edition was eventually followed by the EDuke patch in 2000, the Megaton Edition in 2013, and the 20th Anniversary Edition in 2016.
From the Manufacturer: The Atomic Edition and Plutonium PAK (both version 1.4) supplanted version 1.3d of Duke Nukem 3D on November 27, 1996. On December 12, 1996, another patch, this one unnamed, was released to upgrade version 1.4 of the game to version 1.5, but this merely fixed bugs and did not introduce any new content. Both versions 1.4 and 1.5 are officially known as the Atomic Edition.
