As of about an hour ago, Hearthstone’s single player adventure expansion, Curse of Naxxramas has launched to all players of the game.

The expansion will be downloaded upon opening the game launcher, and during the launch event which will last through to sometime in Early September (although a concrete end date hasn’t been announced) the first wing of the expansion, The Arachnid Quarter, will be available free to all players who have already unlocked all 9 of the playable Hero classes in the game.

The expansion has a further 4 wings to play, which can be purchased with in-game gold (700 per wing) or with real money (5.99 EUR/ 4.99 GBP per wing). Blizzard is also offering package deals to buy more than one chapter at a time for a slightly reduced price.

If you want to go fight the bosses and undead hoardes though, wait a little while. Currently both the North American and the European servers have been experiencing problems that are causing them to crash as the servers are being taxed with the player surge. We will update when both servers are back to normal.
