The latest Hearthstone expansion, Blackrock Mountain, is live and playable today. Following today's release of the Blackrock Depths wing, new content will release each week for the next four weeks.

The expansion is currently available in "all regions" according to the Hearthstone Twitter account. And like the previous Naxxramas expansion, there are multiple ways to purchase it. Each wing separately goes for $7 or 700 in-game gold; all five wings together cost $25.

We recently talked with Hearthstone's developers both about bringing the game over to mobile phones as well as the philosophy behind the new expansion. But the thing most people really want to see are the 31 new cards, which you can find in the gallery below.
