Players of Hearthstone can now preview the cards included in the upcoming premium expansion for the game, Goblins vs Gnomes. All GvG cards are now available in the game’s Arena, allowing players to experience what’s in store with the expansion a week ahead of its release.
To ensure that every player has a chance to see the new cards, Blizzard is awarding one free Arena run to all Hearthstone players who log into the service before December 8.
Additionally, if you’re already in the middle of an Arena run that won’t be finished before December 8, don’t worry—just make sure to log in during the pre-launch period, and you’ll be good to go.
