Instead of building a deck and defeating individual bosses - like in the One Night in Karazahn adventure - players are given just 10 cards and have to defeat eight random bosses in a row, earning new cards after each fight.
The debut trailer for Kobolds and Catacombs emphasized exploring dungeons and finding loot. If you manage to lose, you lose your deck and get to start over with a new hero.
"It's essentially a Hearthstone roguelike and it's our most replayable single-player content ever", Brode explained.
Up until the expansion is released, eager treasure seekers can pre-purchase Kobolds & Catacombs card packs in a special 50-pack bundle for a one-time price of 49.99 United States dollars (one purchase per account) on Battle.net and in Blizzard's game shop, and receive a sparkling, jewel-encrusted "For the Hoard!" card back for free.
Be careful though, because it seems losing a single battle will spell the end of the Dungeon Run. Such cards will pull a minion from your deck and put it directly into play on the board. The upcoming expansion, titled Kobolds and Catacombs, is Team Five's love letter to classic fantasy dungeon crawling gaming.More news: Daylight saving time: 5 tips for a smoother switch Sunday
The most important feature of any collectible card game is how it sets itself apart from other, similar games, and more importantly, if the game's developers can continue to introduce new and unique mechanics.
Cards shown off include Marin the Fox, a character who has a chest filled with "crazy cards" like one that will fill your hand with all of the next card you draw.
Kobolds & Catacombs will launch for Hearthstone sometime in December.
Blizzard pointed out a new keyword as well called Recruit. There are also new class-specific legendary weapons for each of the nine classes. As they progress, they'll bolster their decks with cards looted from defeated bosses, including some immensely powerful treasures exclusive to Dungeon Runs. These legendary weapons will have incredibly powerful effects-the one we saw during the presentation, the priest weapon Dragon Soul, will summon a 5/5 dragon every time the priest casts three spells.
