Hearthstone's next big expansion, Kobolds & Catacombs, is set to launch on December 7. To celebrate, there will be a special kobold themed episode of Critical Role, a fantasy RPG show from Geek & Sundry, on November 30.
The new Hearthstone expansion includes 135 new cards, two new card types called Spellstones and Unidentified items, a new legendary weapon for each nine classes, and a new single-player mode called Dungeon Runs.
Dungeon Runs are a new mode with roguelike elements. Players start with a basic, premade deck and will then encounter a series of bosses. With each victory players will add additional cards to their deck. Defeat all eight bosses with all nine classes and you'll receive a rare card back. But if you lose just once, you start from the beginning with a fresh deck.
As a bonus for logging in when the new expansion drops players can earn one random legendary weapon and three Kobolds & Catacombs card packs for free. As with any new Hearthstone expansion, you can pre-order 50 card packs from the new expansion for $49.99 and unlock a "For the Hoard" card back to your deck.
We played a little of the upcoming Dungeon Run mode at Blizzcon this year before speaking with members of the Hearthstone development team (you can read our extensive interview here). As a single-player mode, Dungeon Runs offer a huge amount of replayability thanks to its ever-changing boss structure. While there are no rare cards or card packs as prizes for completion, Dungeon Runs as a standalone activity are a great way to enjoy Hearthstone outside of online competition.
