Blizzard reveals the newest expansion coming to Hearthstone: Heroes of Warcraft, entitled Mean Streets of Gadgetzan, with 132 new cards and brand new tri-class cards on the way.

BlizzCon offered Blizzard fans a deluge of goodies and update news, and the developer didn't neglect its hit card game, Hearthstone. Blizzard revealed that Hearthstone will be receiving a new expansion, focused on a popular area in World of Warcraft.

Hearthstone: Heroes of Warcraft will be receiving its fourth expansion later this year, entitled Mean Streets of Gadgetzan. The expansion is based upon the desert outpost of the same name in World of Warcraft, and will feature three major crime syndicate groups: the Grimy Goons, Jade Lotus, and Kabal. Each syndicate will host multiple classes, with the Grimy Goons being home to the Hunters, Paladins, and Warriors, while Jade Lotus takes the Druids, Rogues, and Shamans, and Kabal hosts the Mages, Priests, and Warlocks.

Mean Streets of Gadgetzan is also taking a new turn on things, introducing nine tri-class cards. Each clan will feature three tri-class cards, including one Legendary. Unlike prior single-class specific cards, these cards can be used with any of the three hero classes designated by the crime group they belong to. The 132 individual cards released in the expansion will be available as in-game drops via Arena matches, but players can also pick them up with in-game gold or real world currency. A card set booster pack of 50 cards is also available for pre-order now for $49.99, and is set to unlock on December 31st.

This expansion comes hot on the heels of Hearthstone's last add-on, One Night in Karazhan, which was released back in August. Mean Streets of Gadgetzan will be the third add-on for the game and second expansion just this year, showing that Blizzard is making the best of Hearthstone's tremendous popularity and success. Hearthstone received excellent reviews on release, and has since gone on to make a whopping $20 million in revenue per month. While the World of Warcraft physical card game released by Blizzard flopped in comparison to other established card games, its digital counterpart has been a boon for the developer, turning into a massive hit just like World of Warcraft and Overwatch.

The release of Mean Streets of Gadgetzan could potentially shake up the competitive scene for the game, especially with the new tri-class cards in play. However, fans of the game shouldn't fret, as Blizzard has proven that it's willing to make changes as needed, even if it means nerfing specific cards. Given that it ended up making some tweaks to Hearthstone's last add-on, chances are any overpowered cards from Mean Streets of Gadgetzan will see some alterations following its release.

Mean Streets of Gadgetzan will release for Hearthstone later this year on the PC, iPad, and Android and iOS mobile devices.
