Duke Nukem (1991 Video Game) - Sequels

Sequels

Duke Nukem was followed by Duke Nukem II in 1993, featuring the same hero still without the dark sunglasses, and later Duke Nukem 3D in 1996. A third sequel, Duke Nukem Forever, was announced in 1997. Plagued by various developmental problems and delays, the game would later be picked up by Gearbox Software and released in 2011, fourteen years after the game was announced and twenty years after the first game was released. In a DLC (downloadable content) for that game, titled "The Doctor Who Cloned Me", Dr. Proton made his return.

Several spin-offs were developed for consoles only, such as the PlayStation titles Duke Nukem: Time to Kill and Duke Nukem: Land of the Babes, and the Nintendo 64 game, Duke Nukem: Zero Hour. In 2002, Duke Nukem: Manhattan Project was released to commemorate the 10th anniversary of Duke Nukem. It uses a 3D engine and elements from Duke Nukem 3D, but with the side scrolling style of the first two titles.
