Hearthstone: Kobolds & Catacomb’s Dungeon Runs is a win for Blizzard

Hearthstone’s new Kobolds & Catacombs expansion launched today for PC, iOS, and mobile. But the 135 new cards aren’t the most interesting thing to come to Blizzard’s free-to-play hit. Along with the new set, Blizzard has also released Dungeon Runs. This is a new single-player mode that has you picking a class with a pre-made, weak deck, and fighting a series of bosses. After a win, you get to add more cards to your deck. Sometimes you’ll pick a powerful spell or minion only available in this mode, and sometimes you’ll choose between three different packs of three cards that have some kind of synergy. Sometimes you get to choose one of each.

Your goal is to beat eight bosses before dying. If you do lose, you have to start over again. It’s one of the best things Blizzard has ever added to its digital card game, and it’s free.
