The expansion for Hearthstone has been officially launched by Blizzard. Kobolds & Catacombs will introduce 135 new cards and card types that will also include a single-player game mode. The game will also give players some freebies.

When players log into the game, they can get their hands on a random Legendary Weapon card, which is a new type added from the expansion. You will also get three free Kobolds & Catacombs card packs when you log in, to get you started. In a press release by Blizzard, the company said that:

"Kobolds & Catacombs takes Hearthstone players into the bowels of Azeroth, where the dastardly kobolds have been boring tunnels for thousands of years and hiding away scores of ancient treasures." The press release also said that, "Hearthstone players will discover powerful new cards among these riches, including a Legendary Weapon for each class—one of which everyone who logs in to Hearthstone starting today will receive free." 

Regarding additions to the solo content, Kobolds & Catacombs includes the Dungeon Run mode that does not require players to own any cards and are inspired by "the iconic fantasy dungeon crawl, and they're never the same experience twice."
