Blizzard just announced that "Hearthstone's" first adventure pack, "The Curse of Naxxramas" has a release date of July 22nd.

Curse of Naxxramas' first chapter, the "Arachnid Quarter," will be available for free to everyone who logs in during the release date event. The expansion will be released in five chapters distributed on a weekly basis.

After the event ends, the Arachnid Quarter will join the other wings in costing 700 gold, or $6.99. Bundle options are also available for savvy consumers.

Keep in mind that purchasing Curse of Naxxramas wings in bundles does not open or grant access to those wings faster than the one-wing-a-week schedule, but it does ensure that you'll be able to dive into the next challenges as soon as they unlock.

If you play Naxxramas during the launch event and decide to purchase the remaining wings with real money, you'll only have to purchase the 4-Wing bundle to access the remaining wings once they become accessible.

If you unlock additional wings with gold and wish to purchase a wing bundle at a later time with real money to unlock any remaining wings, you can still take advantage of the bundle pricing. For example, if you enter the Arachnid Quarter during the launch event and unlock it for free, then purchase the second wing with gold, the remaining three wings can be purchased with real money at the 3-wing bundle price listed above.

The adventure pack boasts 30 brand new cards, nine of which are class specific. Players will be given the chance to traverse the depths of Naxxramas, doing battle with familiar bosses from the iconic Warcraft raid. Curse of Naxxramas features both normal and heroic modes, and besting all of the bosses on the heroic setting awards players with a unique card back.

Until now Blizzard had only promised we'd be venturing into the cursed ziggurat sometime this month, so it's good to know there is a specific release date.
