Duke Nukem

Duke Nukem is a 1991 platform game developed and published by Apogee Software for MS-DOS. The 2D, multidirectional scrolling game follows the adventures of fictional character Duke Nukem across three episodes of ten levels each. The game's first episode was distributed as shareware. The name was briefly changed to Duke Nukum to avoid trademark issues. Duke Nukem was followed by the similarly-styled Duke Nukem II, in 1993. The series made the jump to 3D graphics with Duke Nukem 3D in 1996, which became the most popular of the three games.
