The game provides an overland map that is used to move between different areas like towns and dungeons. The party can then explore several regions on the Forgotten Realms continent of Faerûn. The rest of the player's party can also be created, unlike Neverwinter Nights 2, but pre-made characters are available if the player is not interested in complete customization. New character creation options include the yuan-ti pureblood and gray orc races, the swashbuckler class, and the hellfire warlock and doomguide of Kelemvor prestige classes. Players first create a character along the lines of the Dungeons & Dragons 3.5 rules by selecting a variety of traits, such as a race, class, and feats. Storm of Zehir is an expansion of Neverwinter Nights 2 and continues the formula of a role-playing video game played from an overhead third-person perspective.

Reviewers were pleased with new features introduced in the game, like more options for party customization and an overland map, but were not impressed with the game's storyline and technical achievements. Storm of Zehir received mixed reviews from critics. The storyline foreshadows the events of the fourth edition of Dungeons & Dragons and follows the adventures of a group of merchants in the Samarach and Sword Coast areas of the Forgotten Realms campaign setting. Storm of Zehir was inspired by older video games like the Baldur's Gate and Icewind Dale franchises. Like previous entries in the Neverwinter Nights series, Storm of Zehir is based on the paper and pencil fantasy role-playing game Dungeons & Dragons, and uses the game's 3.5 edition ruleset. It was released in late 2008 in North America, Europe, and Australia. Neverwinter Nights 2: Storm of Zehir is an expansion pack for the role-playing video game Neverwinter Nights 2, developed by Obsidian Entertainment and published by Atari Interactive.
