Neverwinter Nights 2 Vault has details on the imminent release of a downloadable Neverwinter Nights 2 "Adventure Pack" (thanks Voodoo Extreme). The pack, titled Neverwinter Nights 2: Mysteries of Westgate, is developed by Ossian Studios, creators of the Darkness over Daggerford module for NWN. The add-on is said to offer over 15 hours of gameplay, a new story, new music, and more, and while there's no word on pricing, but the pack is to be released via digital download in autumn 2007, which means within the next two months. Here's a bit:

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.
