BioWare's official Neverwinter Nights website has been updated with the following:
Shadows of Undrentide Modules
Neverwinter Vault has launched a top rated SoU modules list showcasing fan created modules made with the Shadows of Undrentide expansion pack. We have updated our 'Modules' sidepanel to reflect this list, and our Modules section has also been updated! Be sure to check out all the great fan created adventures available on NWVault or Stratics!
Hordes of the Underdark Forum
A new Hordes of the Underdark site will be launching in a few months and will provide an early glimpse into this dark and dangerous world of adventure. Until then, you can watch for online and print previews (such as the preview in the Sept issue of Computer Games Magazine) and you can chat about the expansion in the new Hordes of the Underdark discussion forum!
