The new card is pretty strong, as card advantages are typically important in Hearthstone.
According to Eurogamer, the expansion will introduce 135 new cards as well as free single-player content which anyone can access for free. In this mode players will face a boss and if they manage to defeat it they will be able to add cards to their hands. Whether players prefer to wield magic or arms in battle, strike from the shadows or head on-or have never given any of that much thought-they'll be able to jump right in, create a deck, and get in on the card-slinging action. Coming with the launch of Kobolds & Catacombs, Dungeon Runs will send Hearthstone players on challenging, high-stakes subterranean adventures inspired by the classic fantasy dungeon crawl.
We're on the eve of another Hearthstone expansion, with Kobolds & Catacombs banging on the dungeon door to be let in on December 7 with a batch of new cards and a brand new mode.
The good news is that Blizzard is giving away a few free packs and cards. Lose and your run is over and you'll have to start all over again. 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.
Log in from next Friday and you'll get one of those Legendary weapons and three new card packs for free.
