What are Adventure Packs
Adventure Packs are basically new adventures that are made available through online stores or special offers like the Neverwinter Nights 2 Gold Edition. Like the Premium Modules that Bioware had developed and distributed through their own online store, Adventure Packs allow players to enjoy new content and roleplaying experiences.
Unlike Premium Modules, Adventure Packs are entire campaigns rather than just one module and therefore offer hours of gameplay. Thus far they exclusively take place in the Forgotten Realms campaign world.
List of Adventure Packs
The first adventure pack to Neverwinter Nights 2 (NWN2) is Mysteries of Westgate (MOW) , not yet released and currently waiting on the 1.22 release. It was developed by Ossian Studios. This title has been completed and ready for release since Q4 of 2007. The delay is completely due to work on DRM.
Mysteries of Westgate
The story centers around a cursed mask the player looted from some not further mentioned dungeon he visited in the past and his ordeal to get rid of it. The mask itself, a domino mask, is the symbol of the Nightmasks - a band of thiefs that rule the underworld of the infamous city Westgate. After many attempts to free himself of the mask (and the nightmares it torments the player) a great sage points him toward Westgate in order to find a cure.
DRM Used in Adventure Packs
Adventure packs are not going to be released until Obsidian adds DRM to 1.14, which will keep the modules locked and unplayable without purchase.
