At last night's Blizzard Carnival, Blizzard announced new information on its various games at the Blizzcon Carnival last night. Among them, "Storm Heroes" announced a new arena mode, and joined three new heroes, a variety of new skin. "Storm Heroes" new arena mode demo
The new heroes are Greymane and Lunara, and there is a "double operation: the new hero double-headed ogre Gujar." In the new arena mode, the player will receive three random heroes (including those they do not own). Then choose one of the three heroes to play, and you can pick the hero character. An IMBA model similar to DOTA. "Heroes of the Storm" new hero propaganda video
I believe that everyone should be most concerned about this new "double hero". This hero is very testable to the tacit understanding of the two players, but the hero will not be in the game, only players who bought the Blizzard Carnival tickets can be free. Other players want to unlock this hero must fight two players in the game with this hero to unlock
