Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions.V light is electromagnetic radiation with wavelengths shorter than visible light. UV can be separated into various ranges, with short-wavelength UV (UVC) considered germicidal UV. At certain wavelengths, UV is mutagenic to bacteria, viruses and other microorganisms.
1 Duke Nukem is an homage to the 80s/90s action heroes like Arnold Schwarzenegger, Sylvester Stallone, Bruce Willis, Bruce Campbell, Kurt Russel, Clint Eastwood, John Wayne, Roddy Piper and many other iconic heroes from that time.
The character was redesigned into the present tough guy incarnation by George Broussard and Allen Blum for the 1996 game Duke Nukem 3D. In the dozen or so Duke Nukem games since Duke Nukem 3D, this incarnation of the character has been constant, and voiced by voice actor Jon St. John. A sequel to Duke Nukem 3D, Duke Nukem Forever, had been in development hell since at least 1997.
