When the Curse of Naxxramas expansion is released, you can play Hearthstone by your lonesome. Check out the new details about the solo adventure here.

Game Director Eric Dodds and Executive Producer Hamilton Chu spoke to IGN and revealed details concerning the new cards in Curse of Naxxramas, how players will be able to take on challenges and how the addition of the expansion will change the meta game.

The first unique thing about Curse of Naxxramas will be that you won't receive random cards as rewards. Instead, defeating bosses and challenges will net you specific cards to add to your arsenal.

"There's no randomness at all," Dodds said. "So when you do battle with a specific boss, you get a specific card that is associated with that boss. And then, when you complete a wing and have defeated all the bosses for the wing that's when you get the special legendary that's at the end of that wing."

Speaking of, the only enemies you'll face are boss characters and not just random NPCs of varying class types. In other words, there are no equivalents of "trash mobs" like the ones found in the World of Warcraft version of Naxxramas. You'll face 15 bosses, 9 class challenges and a few legendaries. This means you'll earn about 30 cards, one for each boss, one for each cleared wing, one per class challenge and then another legendary for the final boss, though whether or not this final boss is the last challenge in the expansion is unconfirmed.

We'll let you know when a release date and prices have been set for the Curse of Naxxramas content. Until then, hone your skills in Hearthstone and cobble together the best deck that you can!
