Curse of Naxxramas: A Hearthstone Adventure Launched, Video Released

First Hearthstone: Heroes of Warcraft single-player adventure features fun new cards and frightfully challenging foes
Curse of Naxxramas: A Hearthstone Adventure, a single-player mode for Hearthstone: Heroes of Warcraft, is now available in North America and Europe, for Windows, Mac, and iPad, Blizzard Entertainment announced. The Arachnid Quarter, the first of the Adventure's five sinister wings, is now available - free for a limited time - to all Hearthstone: Heroes of Warcraft players who step into the necropolis during the Curse of Naxxramas launch event, taking place now through early September.
A new wing of Naxxramas will open each week, and access to these four additional wings may be purchased for 700 gold per wing or $6.99 per wing. Players can earn the in-game gold needed to unlock the next wing by completing various quests or emerging victorious from the game's Arena mode - or they can choose to unlock the next available Naxxramas wing using real money.
