As Blizzard Entertainment announced last month, the first Hearthstone expansion of 2018 is The Witchwood, and it’s available now on PC and mobile devices.

“The Witchwood brings a spooky Azeroth fairy tale to life in a uniquely Hearthstone way,” said Mike Morhaime, CEO and co-founder of Blizzard Entertainment. “We can’t wait to see players sink their teeth into all the new cards and start shifting their deck-building strategies around Echo and the other new mechanics.”

The Witchwood, which is named after the spooky forest surrounding the werewolf region of Gilneas, adds 135 new cards to Hearthstone. A new keyword mechanic, called Echo, allows certain cards to be cast multiple times, provided players have enough mana.

In two weeks the new single player adventure mode, Monster Hunt, will become available, as players journey into the titular forest. More details will follow.

The new expansion also kicks off the 2018 Year of the Raven. Each calendar year brings three new major expansions to Hearthstone’s Standard format, while retiring older sets. In this case, the 2016 expansions Whispers of the Old Gods, One Night in Karazhan, and Mean Streets of Gadgetzan are now only playable in Wild, which includes every released card for Hearthstone.

To celebrate the expansion’s release, Hearthstone players can receive three Witchwood card packs and a free random Legendary card just for logging in.

Hearthstone is available on PC, Mac, iOs and Android. It’s rated T for Teen.
