Hearthstone: Heroes of Warcraft is an upcoming online collectible card game from Blizzard Entertainment. It was announced in a presentation by Rob Pardo at the Penny Arcade Expo in March 2013. The game is going into beta in summer 2013, with the release sometime during 2013.
Hearthstone is a free to play game set in the Warcraft universe, supported by the purchase of booster packs. It will be initially available on the Mac and PC, with an iPad version available later, and possibly expanding to other platforms after launch. There will be around 300 cards in the game to start, with more added later; booster packs can either be earned in-game or bought for $1/pack. Each pack comes with five random cards, including at least one "rare". Players can choose one of nine "heroes" which are similar to the classes in World of Warcraft. The game is based around 1v1 matches and will operate through Blizzard's Battle.net. There are currently no plans for cards to be traded between players.
