Duke Nukem 3D features the adventures of the titular macho Duke Nukem, voiced by Jon St. John, who fights against an alien invasion on Earth. Along with Wolfenstein 3D and Doom,Duke Nukem 3D is considered to be responsible for popularizing first-person shooters, and was released to major acclaim. Reviewers praised the interactivity of the environments, gameplay, level design, and unique risqué humor, a mix of pop-culture satire and lampooning of over-the-top Hollywood action heroes. The game’s violent nature, erotic elements, andportrayal of women incited controversy. In “Episode One: L.A. Meltdown“, Duke fights his way through a dystopian Los Angeles. At a strip club, he is captured by pig-cops, but escapes the alien-controlled penitentiary and tracks down the alien cruiser responsible for the invasion in the San Andreas Fault. Duke discovers that the aliens were capturing women, and detonates the ship. Levels in this episode include a movie theater, a Red Light District, a prison, and a nuclear-waste disposal facility. The game features a wide variety of enemies; some of which are aliens and other mutated humans. The LAPD have been turned into “Pig Cops”, a play on the derogatory term “pig” for police officers, with LARD emblazoned on their uniforms. As is usual for a first-person shooter, Duke Nukem encounters a large number of lesser foes, as well as bosses, usually at the end of episodes. Like Duke, these enemies have access to a wide range of weapons and equipment, and some weaker enemies have jet packs.
