Hearthstone: Heroes of Warcraft will be getting its first expansion next month. Focusing on the rivalry between Warcraft's Goblin and Gnome races, the expansion is called, appropriately, Goblins vs Gnomes.
First previewed last month, the expansion features over 120 new cards. These include the new Mech minion type. Mechs can be both neutral and class-specific.
There will be specific Goblins vs Gnomes available in the in-game shop when the expansion launches in December. The pricing will be the same as expert-tier card packs.
