Blizzard moved their free-to-play card battling game “Hearthstone: Heroes of Warcraft” to open Beta yesterday. Players can download the title for PC and Mac here, and begin playing instantly. Any decks purchased in game during the open beta will be available once it launches, and will also give the user extra items and cards in the final build. If you like fantasy and you like cards give this a shot. You can bet BSR will be playing.
