Release Date

Blackrock Mountain Adventure will release on April 2nd, 2015.

Pricing Information

Blackrock Mountain will unearth its secrets over the course of 5 weeks. Starting with Blackrock Depths, each wing opens one week at a time with a new wing opening each week, until all five wings are open.
Each wing within Blackrock Mountain can be purchased with in-game gold or real money, following the same pricing as Curse of Naxxramas. Each wing can be purchased for 700 gold or $6.99 USD. Blackrock Mountain bundle pricing is also available – the bigger the bundle, the bigger the discount! Purchasing wings in bundles does not unlock Blackrock Mountain wings faster than the one-wing-a-week schedule, but it does ensure that you’ll be able to dive into the next challenge and earn new cards as soon as they unlock.
