Here are the cards in Hearthstone's latest Curse of Naxxramas wing

Lots of Hearthstone: Heroes of Warcraft news today: the next wing of the single-player campaign, a new Ranked Play season, and refunds for those who accidentally paid for content twice.

Hearthstone: Curse of Naxxramas is releasing in timed instalments called wings, and the new Military Quarter arrived earlier today.

The single player campaign offers you the chance to win cards in battles with AI bosses. The Military Quarter is dominated by the Four Horsemen, and offers the following cards on normal difficulty:

For those who prefer the traditional versus mode, there's a new Ranked Play season - Hearthstone's fifth - kicking off.

Climbing the ladder to Rank 20 during August will reward you with the Icecrown card back, which can't be obtained any other way. You should also check in this season because it's your last chance to qualify for the Championship Qualifier Tournament.

As usual, the higher you climb in Ranked Play this season, the more bonus stars you'll receive for next season - which gives you an immediate boost if there are more goodies to give away. Visit Battle.net for more information.

Finally, Blizzard has addressed issues with payment for Curse of Naxxramas content. Some players were double-charged; check your card statement to see if you were affected. If you purchased the content directly from Blizzard, you've been automatically refunded - but if you puchased through iTunes, you'll have to make a claim with Apple.

Visit the Battle.net forums for all the details.

Thanks, TouchArcade, Shack News.
