Hearthstone’s latest expansion, ‘Mean Streets of Gadgetzan,’ coming early December

Hearthstone’s latest expansion, Mean Streets of Gadgetzan, has been announced during the Blizzcon opening ceremony.

The expansion will arrive in the game next month, adding 132 new cards.

Themed around the Gadgetzan trading outpost of the Warcraft world, the expansion is along the more lighthearted lines of Goblins vs Gnomes.

The expansion will also add tri-class cards across three theme crime families. A few cards in the set will be available to three different classes, including a legendary leader.

The icon under the mana cost indicates which family the card belongs to, and changes color to show which classes it is available to?—?in this case Warlock, Priest and Mage.

Kazakus also includes a brand new mechanic to create brand new custom spell cards, choosing from a series of Discover choices.

More cards will be revealed in the Hearthstone developer panel later today.
