It's April 2nd, that means Hearthstone's Blackrock Mountain expansion is now live for all players in the North America. Unfortunately, folks over in Europe and Asia will need to wait until April 3rd for Blackrock to go live. Blackrock Mountain brings players a bevy of new bosses and 31 new cards to play around with. Hearthstone players can expect: "In Blackrock Mountain, Hearthstone players find themselves amid a war between powerful forces battling for control of the legendary mountain. Deep within the mountain's core, duelists go toe-to-toe against fierce minions, including Dark Iron dwarves, fire elementals, and dragons, while facing off against legendary menaces from the Warcraft universe, such as Ragnaros the Firelord. Card-slingers who extinguish these villains will reap a mighty reward—31 scorching new cards inspired by the mountain and its denizens, bringing a wealth of new tactical options to the ever-evolving Hearthstone metagame." The Blackrock Mountain expansion can be purchased right within the Hearthstone app for $24.99, or $6.99 per wing. It is worth noting that Blizzard is currently planning to release and iPhone version of Hearthstone sometime in the Spring.
