You know the drill by this point.
Hearthstone: Curse of Naxxramas’ third wing, the Military Quarter, is now available to purchase for $6.99 or 700 gold. Within the Military Quarter, you’ll face off against Instructor Razuvious, Gothik the Harvester, and the Four Horsemen. As before, class challenges and the Heroic difficulty await once you finish the quarter.
So what are you waiting for? Go explore the Military Quarter! I’ve attached the cards that you’ll obtain after completing the wing after the break.
