Tavern Brawl mode debuts tomorrow in Hearthstone: Heroes of Warcraft

If you’re a Hearthstone fanatic, tomorrow’s going to be a great day for you.

Blizzard’s digital card-collecting game debuts its Tavern Brawl mode tomorrow. This brings a multiplayer mode akin to the single-player challenges found in Hearthstone’s adventures, Curse of Naxxramas and Blackrock Mountain. It’s a head-to-head mode that challenges players to outwit opponents in special matches. It’s also a key move in that it adds free content to a free-to-play game that could use more — an important component in player retention for online and mobile games.
