If you’ve wanted a single-player mode in the digital trading card game Hearthstone, then we have some good news. Blizzard announced Curse of Naxxramas, a single player adventure mode, at PAX East today.

Naxxramas is a floating cemetery from Warcraft's extensive lore, and players can use their favorite deck to battle the creepy bosses in the five different wings of Naxxramas. Similarly to the arena mode, there is a cost to entering Naxxramas’ wings, which can be paid with either in-game gold or real money, though how much it will cost is currently unknown.

The wings unlock one week at a time, over the course of five weeks, and entry into the first wing is free. At the end of each wing, Players earn a new legendary card. Curse of Naxxramas is adding a total of 30 new cards to Hearthstone. 

The bosses themselves have new abilities, minions, art, and speech options from the already established characters in Hearthstone. There is also different challenges for entering as specific heroes that earns players class-specific cards.
