and also a mad scientist) to Dr. Proton, the main antagonist of Duke Nukem. The side scrolling element also pays homage to the original. Duke's primary enemy in the game was originally supposed to be his old nemesis Doctor Proton, but this was changed to avoid possible continuity clashes with Duke Nukem Forever. (though in the end Forever does not feature Proton at all, the DLC for Duke Nukem Forever called The Doctor Who Cloned Me featured the return of Proton.) Development In 1996, George Broussard was interviewed about future 3D Realms projects: he said that a Duke Nukem side-scroller called Duke Nukem Forever was in production and was supposed to come out by Christmas 1997. The project was later cancelled, with the name Duke Nukem Forever reassigned to the true Duke Nukem 3D sequel.

This has been detailed a few times online by 3D Realms' webmaster Joe Siegler in their online forums,. In a June 2006 forum post, Siegler said of the situation: Sometime after the bankruptcy, the official website for Duke Nukem: Manhattan Project was allowed to lapse and as was registered by a domain squatter. Fortunately, before all the materials were lost, Joe Siegler was able to recover a copy of the contents of the official Duke Nukem: Manhattan Project website from a former ARUSH employee, and now hosts the former contents on the 3D Realms Website. In late February 2009, the online gaming distribution site GOG.com announced some Apogee Software titles as being available in the future for sale on their site. On this list was Duke Nukem: Manhattan Project. Reception The PC version received "generally
