The latest addition to the Adventure Mode in Hearthstone is coming later this week and will feature new locations, cards, foes, and card battles to take part in. Called The League of Explorers, this new expansion will retail for $19.99 USD and be released over the course of a month (with one new location per week).

For those addicted (and rightfully so) to the wonderful Hearthstone you'll no doubt snap this up. In addition to the once-off cost The League of Explorers will also be available in chunks, one location at a time for 700 gold or $6.99 USD each.

The League of Explorers introduces four intrepid adventurers—Elise Starseeker, Reno Jackson, Sir Finley Mrrgglton, and Brann Bronzebeard—and invites players to join their journey through a series of exotic destinations, some familiar and some new, to recover an artifact of immense power. These brave explorers will face many perils as they navigate through the Temple of Orsis, Uldaman, the Ruined City, and the Hall of Explorers in hopes of discovering lost artifacts that will lead them closer to the relic. Escaping giant boulders and emerging from all of the locations in one piece will reward adventurers with a combined total of 45 treasured new cards, bringing a slew of new tactics to the game.

Hearthstone is freely available on Windows, Mac, iOS, and Android.
