The new expansioon for Hearthstone: Heroes of Warcraft, Blackrock Mountain, pits players against a host of iconic foes across five challenging, magma-packed wings. Players who can see it through the end will be rewarded with a host of new cards to add to their collection.

In Blackrock Mountain, Hearthstone players find themselves in 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 can conquer these villains will reap a mighty reward, 31 new cards inspired by the mountain and its denizens, bringing a wealth of new tactical options.

“Adventure Mode challenges players to think outside of the box and come up with creative new strategies,” said Mike Morhaime, CEO and cofounder of Blizzard Entertainment. “After the new bosses and unique mechanics in Blackrock Mountain put their skills to the test, we can’t wait to see how players use all the new cards in their decks.”

The first wing of Blackrock Mountain, Blackrock Depths, is now open to challengers, with one additional wing opening each of the following weeks throughout April. Each of the Adventure’s five wings is available for purchase separately for 700 in-game gold per wing or for £4.99 per wing on PC, Windows and Android tablets, and iPad. Or alternatively a complete Blackrock Mountain bundle package is also available for £17.49 on PC, Windows and Android tablets and £18.99 on iPad.
