Blizzard announced yesterday their first ever expansion pack Goblins vs. Gnomes will launch across all platforms in the U.S. starting December 8. The game will expand to Europe, Taiwan, China and Korea starting December 9.
First revealed last month during BlizzCon the expansion will add 120 new cards to an already impressive collection. Cards can be acquired through arena runs, purchased in packs or crafted individually much like your standard cards. The new packs will have a unique virtual wrapper to differentiate from regular packs. Alongside the expansion will be a number of balance changes including having the mana cost increased by one to three notorious cards; Soulfire, Gadgetzan Auctioneer and Flare.
You can see all the newly announced cards on the Hearthstone Facebook page or at HearthPwn.com. For anyone new to the game you can begin playing for free today at us.battle.net/hearthstone
