Blizzard Entertainment announces the North American release of the Goblins & Gnomes expansion for Hearthstone, adding more than 120 new cards to Blizzard's virtual-card strategy game:

Goblins vs Gnomes throws players in the middle of the epic rivalry between Azeroth’s audacious goblin engineers and their equally “adventurous” gnomish counterparts—and these pint-sized tinkerers are ready to stir up trouble. Their incredible inventions and mechanical monstrosities are marvelous to behold … but when Hearthstone players deploy them in a duel, the results can be quite unpredictable.

Goblins vs Gnomes card packs are available in-game now for gold or real-world currency, priced the same as Expert card packs from the original Hearthstone: Heroes of Warcraft set. Players can also win Goblins vs Gnomes cards as rewards in the Arena or craft them using Arcane Dust earned from disenchanting cards in their collection.
