Duke Nukem 3D

Duke Nukem 3D is a first-person shooter video game developed by 3D Realms and published by GT Interactive Software. The full version of the game was originally released for MS-DOS in May 1996 as version 1.3d, while the shareware version was released on January 29, 1996. It is a sequel to the platform games Duke Nukem and Duke Nukem II, published by 3D Realms.
