Hearthstone single-player expansion out now

Blizzard has officially launched Curse of Naxxramas, the single-player expansion for Hearthstone.

Naxxramas will give players access to five different 'wings', where there'll be progressively harder boss fights, new cards and a new game board.

The first wing, Arachnid Quarter, is accessible for free during its first month of availability.

Then it will be priced at the same level of the other wings, either £4.99 GBP or 700 in-game gold each.

However there is an option to purchase all five wings together for a reduced price of £17.49 GBP.
