New Hearthstone Expansion The League of Explorers Announced, Adds 45 New Cards

Today during the BlizzCon 2015 opening ceremony, Blizzard Entertainment announced the next Hearthstone expansion. It's called The League of Explorers and adds 45 new cards and a fresh mechanic called "Discover." The announcement comes as Hearthstone's player base climbed to 40 million users.

You won't have to wait too long to play League of Explorers, however, as its first wing arrives on November 12 across PC and mobile devices. You can buy all of the League of Explorers content for $20, or each of the four wings for 700 gold or $7 each. New wings will be added every week after November 12, with the exception of Thanksgiving week.

Featured in League of Explorers are four new "intrepid adventurers": Elise Starseeker, Reno Jackson, Sir Finley Mrrgglton, and Brann Bronzebeard. There are 45 new cards to collect, too.

The four wings of new cards include "fiendish bosses, puzzling traps, and ancient mysteries for you to discover." There are also new legendary cards to collect. In addition, League of Explorers packs in new class challenges, more game boards, and a new keyword, the aforementioned Discover. It also comes with an "extra-tough" Heroic Mode.

We'll have more details on League of Explorers, including images of the cards, later on.
