Blizzard Entertainment have announced that Curse of Naxxramas: A Hearthstone Adventure will be making it’s way to fans soon. Very soon, actually as the content will be making it’s way to Windows, Mac, and iPad on July 23 in Europe. It will see monsters of Hearthstone inhabiting the halls of Naxxramas, defending against the heroes of Hearthstone. If you can defeat them, you will be rewarded with new cards for your collection. The first wing of this content to be released – Arachnid Quarter, will be free to play during the launch event, which will last about a month. Those brave enough to step foot into the Arachnid Quarter during the launch event will unlock it permanently for free.
