The Hearthstone team has revealed the game’s upcoming Madness at the Darkmoon Faire expansion, and everything we’ve heard so far suggests it could be the game’s most meaningful expansion yet.

The upcoming expansion will also feature the usual number of new cards (135). Among the new cards are the return of the “Old Gods” Legendaries (C’thun, N’Zoth, Yogg-Saron, and Y’Shaarj) who each produce some potentially game-changing effects when played. There’s also a new keyword called “Corrupt” which basically allows you to upgrade a corrupted card by playing a card that costs more than it does. Interestingly, Blizzard has announced that they will supplement that set by releasing 35 card mini-expansions between the release of Darkmoon Faire and the debut of Hearthstone‘s next full set sometime in 2021.

The expansion itself looks like a lot of fun, but the real draw here is how the release of this expansion will coincide with the release of many of the features that Hearthstone fans have been requesting for years.

The highlight of those features is the addition of a new game mode called Duels. Essentially a PvP take on Hearthstone‘s popular Dungeon Runs, Duels sees two players create a starter deck of eligible cards that they’ll be able to expand via rewards offered at the end of every match. Players will be able to participate in a free “Casual” version of the mode that will be released later today for those who pre-order the upcoming expansion, but Blizzard is also developing a “Heroic” version of the mode (featuring buy-ins and rewards) that is scheduled for release on November 17.

Additionally, achievements are finally coming to Hearthstone via an expanded profile page that more accurately measures your progress. Achievements will include everything from winning a game in a certain way to reaching specific in-game milestones.

Honestly, the Hearthstone team has done a fantastic job over the last year or so of taking fan feedback to heart by not only adding the most requested features but by updating the game in a timely fashion that addresses concerns of creative complacency. Everything we’re hearing about this upcoming expansion suggests that trend will continue into 2021.
