Hearthstone's first ever expansion pack, Goblins vs. Gnomes, will be arriving next week, Blizzard announced in a press release today.
The expansion will be available across all of Hearthstone's platforms (Windows, Mac, and iPad) in America starting on Monday, Dec. 8. It will expand to Europe, Korea, Taiwan and China the following day, Dec. 9.
First revealed last month during BlizzCon, Goblins vs. Gnomes will add 120 new cards to the digital card game. Blizzard says the new cards can be purchased in packs, crafted individually or won through arena runs, just like current cards. Goblins vs. Gnomes packs will have a different virtual wrapper to differentiate them from regular packs.
Earlier today, Blizzard also announced some upcoming balance changes coming to Hearthstone. It's possible that these changes will be implemented alongside the expansion launch.
