Once known as Blizzard All-Stars, the new MOBA title from Blizzard Entertainment has been renamed as Heroes of the Storm ahead of its public reveal at BlizzCon 2013. The name was first rumored to be a possible World of Warcraft expansion some months back.
Seen below is the first trailer back when it was Blizzard All-Stars. For those who did not know, characters from Blizzard games will be playable here, in the veins of Dota 2 and League of Legends. There is currently no official confirmation of the game mechanics.
