Atari today announced that a Neverwinter Nights 2 expansion pack titled Mask of the Betrayer is on the way. Developed by Obsidian Entertainment, which also handled development of the original game, the expansion pack will feature a new campaign, as well as new feats and spells, races, monsters, weapons, items and more. Neverwinter Nights 2: Mask of the Betrayer will be released this Fall.

In Neverwinter Nights 2: Mask of the Betrayer, players are transported back to the Forgotten Realms shortly after the events detailed in the original Neverwinter Nights 2. Following the climactic battle against the King of Shadows, the player awakens alone and stranded deep beneath the earth. Surrounded by a horde of evil spirits, the player embarks on an epic adventure that reveals his true destiny. [...] "Neverwinter Nights 2: Mask of the Betrayer's engrossing campaign will conclude the storyline that began in the original Neverwinter Nights 2 and focus on combat, exploration and classic D&D dungeon-crawling," said Feargus Urquhart, CEO, Obsidian Entertainment.
