Neverwinter Nights: The Shadows of Undrentide is the 20-hour expansion to the original take. This PC release from Atari, BioWare, Wizards of the Coast and Floodgate Entertainment is rated Teen for blood and violence. The original Neverwinter Nights is necessary to play this expansion.

Those who thrilled to the adventures of the original Neverwinter Nights title will doubtless be excited for this title, and with good reason. While sporting the same game mechanics, Shadows adds new character classes, including five prestige classes, new mobs, weapons, feats, skills, and spells. The game also comes with the new Neverwinter Aurora Toolset Wizard, and includes three new tilesets. Players can create their own adventure within the Neverwinter Nights universe.
