Back in March, Blizzard finally released the long-awaited 'Hearthstone: Heroes of Warcraft' for the Mac and PC. Then a month later, the company responsible for games like Diablo III, World or Warcraft and many others, launched Hearthstone on iPad as well, promising an iPhone version to be coming later. Blizzard announce today, Hearthstone would be getting its first expansion 'Curse of Naxxramas' on July 22nd. Although there was no word on the iPhone version of the game, the expansion will work cross-platform on iPad as well as desktop. Via Blizzard's Blog: "Are you prepared to face the horrors lurking within the dread necropolis Naxxramas? Curse of Naxxramas: A Hearthstone Adventure is just about ready to open its gates to the world. There’s a whole host of undead monsters inhabiting the halls of Naxxramas, ready and waiting to defend their lair against Hearthstone’s heroes. If you . . . somehow . . . manage to defeat them, you’ll be rewarded with ghastly new cards for your Hearthstone collection! Curse of Naxxramas goes live in the Americas region for Windows®, Mac®, and iPad® on Tuesday, July 22, starting with the Arachnid Quarter, the first of five creepy wings that will be released weekly after the gates are opened. The Arachnid Quarter will be free to play during the Curse of Naxxramas launch event, which will last roughly a month. Those brave enough to step foot into the Arachnid Quarter during the launch event will unlock it permanently for free." Blizzard will allow folks playing the card battle game to play through the first wing, known as 'The Arachnid Quarter'. After that, players can choose to buy each of the other wings in the game for $6.99, or 700 in-game gold. As a player myself, I can tell you that gold take a pretty long time to get, and normally used for buying card packs. Hearthstone: The Heroes of Warcraft is currently available to play on the iPad and iPad Mini. Due note, the game is very processor heavy and has some trouble running smoothly on my iPad Mini 1st gen. However, Hearthstone is free-to-play and players should have no problem battling their way up without spending any money on in-app purchases.
