Hearthstone‘s next expansion is putting on its best faux-Jamaican accent for a big blue throwdown. Launching in December and unveiled at BlizzCon today, Rastakhan’s Rumble tells the story (through the act of card-battling) of a once-in-a-generation tribal contest. Trolls from around Azeroth are assembling to beat each other black and (more) blue in order to impress the Loa spirits and King Rastakhan in a big arena rumble. It’ll also feature its own new solo campaign mode. Check out the cheerful musical trailer below – a staple for new Hearthstone announcements.
