Duke Nukem is a video game series named for its main character, Duke Nukem. Created by the company Apogee Software Ltd. (now 3D Realms) as a series of video games for personal computers, the series expanded to games released for various consoles by third-party developers. The first two games in the main series were 2D platformers, while the later games have been a mix of first-person and third-person shooters.
