Atari and Wizards of the Coast has announced that development is complete on Neverwinter Nights 2: Storm of Zehir. Developed by Obsidian Entertainment, the second expansion pack for Neverwinter Nights 2 aims to deliver a thrilling original D&D adventure made even more exciting by a host of new gameplay features.

Neverwinter Nights 2: Storm of Zehir builds on the strong tradition of Dungeons & Dragons computer games by marrying old-school concepts like full party customization and dungeon crawling with new innovations, such as a fully 3D Overland Map feature which allows for free exploration of the non-linear game world.

The 20 to 30-hour campaign in Neverwinter Nights 2: Storm of Zehir introduces new classes, including the fearsome Hellfire Warlock and the daring Swashbuckler, as well as brand-new spells, creatures, and playable races. Fans of the compelling multiplayer features of Neverwinter Nights 2 will be able to play through Storm of Zehir's campaign in the online cooperative mode, while modders can use the included editor to create their own campaigns and Overland Maps to share online.
