Neverwinter Nights 2: Mysteries of Westgate is the first full featured Adventure Pack available from Atari. Set in the infamous Forgotten Realms city of Westgate, players find themselves in possession of a powerful but cursed treasure that threatens to destroy them. Linked to the underworld organization known as the Night Masks, the treasure will draw players into a city-spanning clash between warring factions. Players must choose their allegiance in order to break the curse and ultimately uncover a plot that threatens Westgate itself.

From the creators of the critically-acclaimed Neverwinter Nights module, Darkness over Daggerford, Neverwinter Nights 2: Mysteries of Westgate will feature a non-linear, open-ended single-player campaign with numerous side quests covering more than 15 hours of game play. Atari's new Adventure Pack will also feature 3 new companions; an entirely new underground sewers tile set themed after the seedy underbelly of Westgate; a host of new monsters to do battle with, including some truly epic foes; an exciting new and original musical score; as well as thousands of new lines of professionally recorded dialogue.
