The sequel, Duke Nukem II, is more than four times larger and took advantage of 256-color Video Graphics Array (VGA) graphics, Musical Instrument Digital Interface (MIDI) music, and digitized sound.

The name was later determined not to be trademarked, so the spelling Duke Nukem was restored for Duke Nukem II and all successive Duke games.

When Apogee learned that the name 'Duke Nukem' might have already been trademarked for the Duke Nukem character from the television series Captain Planet and the Planeteers, they changed it to Duke Nukum for the 2.0 revision. The original game has three episodes, the first distributed as shareware. It is a two-dimensional platform game for the IBM PC and features 320×200, 16-color EGA graphics with vertical and horizontal scrolling. The original game, Duke Nukem, was released in 1991.
