Blizzard just announced Hearthstone's third adventure that - surprise! - comes out next week.
The League of Explorers comes out on Thursday, 12th November 2015. As a Hearthstone adventure, you play against computer-controlled opponents with unique powers and cards. If you beat them, their cards are yours.
The League of Explorers contains four wings, each with an assortment of bosses (the first wing comes out next week - the others follow). There are also nine new class challenges (here you use a special pre-built deck). Win, and the new class cards are yours.
There's a new game board, and a new mechanic: Discover. This lets you dig up cards and select the one you need the most.
Trailer is below.
