If you’ve been eagerly awaiting the expansion for Blizzard’s card-collecting game, Hearthstone, your wait is over. The content patch is live and available now.

With “more than 120 new cards,” Blizzard says, “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.”

If you log into the game between now and December 19, you’ll also get three free Goblins vs. Gnomes card packs.
