Hearthstone's expansion announcement at Blizzcon this year may have been expected, after all, updates to the game have started hitting with regularity. But the big difference this time is way the team is changing up its approach to single-player content. At the show, we talked with lead mission designer Dave Kosak and lead UI designer Max Ma to learn how exactly the new Dungeon Run will work, and to get a few early tips for what sounds like a challenging new mode. In addition, we learned the codename for this expansion before it was revealed to the world!

And in case you missed any other Hearthstone announcements at the show, here are all of the cards revealed so far and the new intro trailer. We also have a roundup of all the biggest Blizzcon 2017 news, from Overwatch's new hero to World of Warcraft's next expansion.
