Announced moments ago by executive producer Hamilton Chu during the BlizzCon keynote, Mean Streets of Gadgetzan is set in a city "where gangs rule the streets." I hear it's "full of swindlers and cheats."

This thieves' paradise will add three new classes to the card combat game. These include the brute mobsters, the Grimy Goons, the sneaky assassins syndicate Jade Lotus, and a rogue spellcasters legion The Kabal.

The Grimy Goons have a card that offers a "piranha launcher" attack. Yes, it's a gun that shoots sharp-fanged fish, naturally. The Lotus' Assassin gains a stealth ability by slaying someone, and the Kabal's Talonpriest gives friendly minions a health boost.

Each new class will have its own leader. For example, the Kabal's leader is Kazakus, a character capable of crafting spells. If your deck has no duplicates you get to create a custom spell by merging other spells together.
