According to 3D Realms veteran and Duke creator George Broussard 'there is no real game to play', adding 'most of what's there are small level snippets, level designer tests, or some fake build out areas for an E3 demo'.

Which comes with the build, source code, and the Unreal Editor used to create the maps. With reports of the game's E3 2001 era build surfacing in recent days, it's already found its way online. Which makes sense when you consider that development began at 3D Realms in the 1990s, with the final product finished and released by Gearbox in 2011. In other news, Babylon’s Fall player count has dropped into the single digits, and Resident Evil Re:Verse may finally be releasing soon.Duke Nukem Forever features one of the most troubled, storied, and talked about development periods in the history of games. However, the leaker was pretty responsive to questions, so we may finally get a chance to see what may have been. The group behind the leak says it’ll be releasing it in June, but this wouldn’t be the first time a Duke Nukem Forever build was dangled in front of people on 4Chan only to have the poster disappear. As of now, we don’t know how functional the build is outside of the few videos and images we’ve seen. The UI is obviously a work in progress, and many of the levels are just blockouts with no enemies or content. All the content shown at E3 2001 is included, and all weapons are functional except for the chainsaw and the freeze gun. The leaker says almost every chapter is present in some form and that a huge chunk is playable. Surprisingly, there’s a lot more material here than one would expect for a game that wouldn’t release for ten more years. We didn’t get much hard info, but a smattering of videos and images responding to user requests easily verified that the leaker is in possession of a build of the game from around E3 2001. The Duke Nukem Forever leak occurred on 4chan’s /v/ board, according to the enthusiast site Duke4.
