Obsidian's announced a new add-on for D&D RPG Neverwinter Nights 2, titled Storm of Zehir.
The expansion will see players "travel the Sword Coast and Samarach using the open ended exploration of the new Overland Map," takes in a plot "in the aftermath of the defeat of the King of Shadows," and involves "evil, shapeshifting, serpentine Yuan-Ti."
You can't say fairer than that. Storm of Zehir will include 15 hours of play and new classes, spells, creatures, and playable races.
More on Blue's. There's no date on there, as far as we can see.
