Duke Nukem Wiki

Loading screen from version 1.2

Duke Nukem 3D v1.2 is a leaked prototype of Duke Nukem 3D. Although the leak did not occur over the Internet, its existence was first confirmed by 3D Realms in 1996 and was independently confirmed by Richard "TerminX" Gobeille in 2014.

Statement by 3D Realms

The file "README.TXT" included with version 1.3d of Duke Nukem 3D explains that, despite the public appearance of having skipped from version 1.1 to version 1.3, there was in fact a version 1.2 that was leaked in advance of the official release. The full statement reads as follows:

What's new in Duke Nukem 3D v1.3D?
* Why version 1.3D and not 1.2? There was a minor leak of version 1.2, so
we bumped the version number. V1.2 is NOT official and if you have it,
delete it, it's illegal, and get v1.3D.
* The major addition to v1.3D is that the full version of the game is done as

Independent confirmation

In 2014, Richard "TerminX" Gobeille signed a non-disclosure agreement and was given an archive of project development data for Duke Nukem 3D. In the Duke4 forums, a user asked whether a shareware version 1.2 ever existed, and Gobeille responded by posting a screenshot of the loading screen from the non-shareware version 1.2. He proceeded to explain minor details about the game's contents and how it compared to the final release.


There are no known screenshots or videos from version 1.2, and because the leak did not occur over the Internet, the game's contents are only known to Gobeille and the original developers. However, Gobeille has shared the following information about the contents of the game:

  • Overall, version 1.2 is nearly identical to the final release.
  • The "Quick Kick" function for the Mighty Foot works like in versions 1.4 and 1.5, without the double-kick glitch from version 1.3d.
  • Battlelord Sentry sprites use palette 19 instead of palette 21.
  • Stadium is significantly different (possibly corresponding to this leaked screenshot by Gobeille). By comparison, the commercial release reverted to one of the earliest builds of the level, circa 1994.
  • The Overlord uses its original design from pre-release screenshots, with a machine gun in its crotch.
  • Hotel Hell includes a giant mirror along the wall beside the front desk of the hotel, allowing the player to see the Battlelord Sentries before coming around the corner.
