Hearthstone: Heroes of Warcraft’s third Blackrock Mountain wing, Blackrock Spire, is now live

Hearthstone: Heroes of Warcraft is now out on phones, and you can use your pocket-sized devices to take on the latest add-on for the card battler.

Publisher Blizzard has just unlocked Blackrock Spire, which is the third part of the Blackrock Mountain downloadable content. This gives you three new bosses to fight against as part of the continuing solo adventure. This is just one of the ways that Blizzard is keeping fans of its first free-to-play and mobile game coming back for more, and it’s working as Hearthstone is one of the top-grossing apps on iOS and Android. The developer is selling this new episode for $7, but you can buy the entirety of Blackrock Mountain for $25 — that will save you a few bucks over purchasing each wing separately.
