After quite a few teasers and an endless parade of card previews, Hearthstone's newest expansion Rastakhan's Rumble has now arrived for both PC and mobile. It brings with it 135 new cards to collect, a Dungeon Run inspired singleplayer event to mess around with, a variety of new mechanics to explore, as well as a brand new keyword by the name of Overkill that gives you benefits whenever you deal more damage than an enemy has health.

You can get a pretty good idea of what all these new mechanics have to offer, as well as what the cards themselves are all about, by visiting the official list. But for now, allow me to share with you the recently posted and rather musical announcement video. Have a gander, the Hearthstone team really knows how to make a catchy trailer:

As for the Rumble Run singleplayer event, it's pretty much exactly what you would expect. You have to select a champion at the very start of the run which defines your class, after which you'll be able to ally yourself with the various Troll Loa in order to enhance your deck and actually stand a chance against some of the tougher bosses. It's a pretty fun game mode, so even if you're not much of a Hearthstone player, I'd highly recommend giving it a couple of tries.
