Hearthstone: Knights of the Frozen Throne — creating Death Knights and Un’Goro’s legacy

Hearthstone is as alive as a game can be, but it’s about to get a heaping dose of death. The digital card game’s next expansion, Knights of the Frozen Throne, comes out in August for PC and mobile. It’ll add 135 new cards, including some that will turn Hearthstone’s classes into Death Knights, which will give them new powers.

Expansions are Blizzard‘s most important tool for keeping Hearthstone popular. Each time it releases a new set of cards, it gives fans a reason to spend more money in the game (mostly on packs so that they can acquire all of those new cards). But expansions also keep the game fresh. New cards means new strategies and new decks, changing the way everyone plays Hearthstone and starting a new era of deck discovery. For many, Hearthstone is at its most fun right after a new expansion launches.
