Hearthstone expansion Goblins vs Gnomes coming this December

120+ new cards for PC, Mac, and iPad

This trailer for Goblins vs Gnomes, an expansion for Hearthstone: Heroes of Warcraft hitting next month, sure is fun. I like it when videogame trailers are basically just songs.

The expansion will add more than 120 cards, including the new Mech minion type, which you can buy in-game using gold or real-world currency. Start saving! They’ll be available in Goblins vs Gnomes-specific packs that are priced the same as Hearthstone expert card packs.

Blizzard also plans to roll out a spectator mode alongside the expansion. Once live, the feature will be enabled by default so be sure to turn it off if you’re fearful of friends’ prying eyes.
