Blizzard Entertainment revealed that Blackrock Mountain is coming to Hearthstone in April. The newest addition to the Adventure Mode will introduce a slew of new hot-headed bosses to put players’ dueling skills to the test.

The Blackrock Mountain Adventure will throw players in the middle of a war between powerful forces battling for control of the mountain. Duelists will encounter fierce minions, including Dark Iron dwarves, fire elementals, and dragons, before facing off against iconic menaces from the Warcraft universe, such as Ragnaros, the Firelord. Card-slingers who take down these villains will reap a mighty reward: 31 scorching new cards inspired by the legendary mountain and its denizens, bringing a wealth of new tactical options.

Blackrock Mountain, which will be available on PC, Windows and Android tablets, and iPad, will open up one wing per week over the course of a month. As with the game’s first Adventure, it will be accessible for either 700 in-game gold per wing or for £4.99 per wing with the entire Adventure purchasable for £17.49 on PC, Windows and Android tablets and £18.99 on iPad. Preorders (real money only) for Blackrock Mountain will be available starting March 19, and will include an exclusive card back to those duelists ready to take on what lies within the mountain when it opens.
