Blizzard have announced that Hearthstone: Heroes of Warcraft will be receiving a new single player campaign, titled Curse of Naxxramas.
Revealed at PAX East, Curse of Naxxramas is based off a raid dungeon of the same name in World of Warcraft. For those unfamiliar to Warcraft lore, Naxxramas is the floating necropolis for the powerful archlich Kel’Thuzad that was originally positioned in the Eastern Plaguelands (and later in Northrend during the events in Wrath of the Lich King).
Like the World of Warcraft variant, Curse of Naxxramas will be divided into five wings, with the first being The Arachnid Quarter. A new wing will be available each week, allowing players to battle against more bosses and gain more cards. The final wing will release in the fifth week, where players will battle two notorious bosses for the final reward.
Once a wing is released, its cards are added into the Arena mix for everyone to play with, regardless of whether the player has gone through the adventure.
Blizzard have mentioned that a total of 30 cards can be obtained from the Curse of Naxxramas adventure, where players can add these cards to their decks for either Play or Practice mode. The set of 30 cards are optional to obtain and are not necessary for being competitive at Hearthstone.
In addition to the new adventure mode, class challenges will be introduced. This allows players to test their skills with each class, where they have to win a duel using a predetermined deck. Upon victory, the player is rewarded with one of the 30 adventure cards for that specific class.
Curse of Naxxramas will release at a later time, with the first wing free for all players. The remaining four wings can be purchased with in-game gold or with real money.
