Latest Heroes of the Storm character is controlled by two players simultaneously
Heroes of the Storm has a very interesting new champion.
Cho'Gall is a two-headed character, composed of two brothers sharing one body.
To reflect this in-game, the character is controlled by two players. The one who chooses Cho controls the character's movement, while Gall can trigger the mount ability, which is actually a burst of speed rather than a thing you climb onto.
The two characters have seperate abilities on separate timers, so both players are active and participating. Take Cho'Gall down, and you'll earn two kills - but that won't be an easy task. Blizzard says Cho'Gall is something like a raid boss (which Cho'Gall is, in World of Warcraft).
It's an interesting idea! MOBAs are best when players communicate and work together, and this very powerful hero directly encourages that. Probably not a newb pick, though. Take a look at the video below.
