Duke Nukem 3D Atomic Edition is available to purchase from GOG.com. With your $5.99 purchase, you not only get a Windows XP/Vista compatible download but a multitude of extras: manual, artwork, Duke SMS tones, hi-res wallpaper, and avatar. The Atomic Edition even includes a fourth bonus episode, new weapon, and enemies.
The game itself is considered by many as a humorous take on Doom and by others as a politically incorrect and controversial game. It may be all of these things, but one thing is certain, Duke Nukem 3D is good blasting fun and an all time PC classic.
