Apparently Dark Elixir will be used to buy new hero unit's, you need a town hall level 7 to buy the collector for dar elixir, which you can see in the image above. Below is a sneak peak of 2 new hero units in action, also apparently hero units don't die, they need time to regain health before they can attack again.



In the video you can also see some new walls, the walls there are either level 9 or 10, both walls will be in the new update, the other walls are here in a photo Supercell posted on Facebook




The new update will also show you troop donation numbers for your clan, so make sure you're generous!



The coming update is looking pretty big at the moment, and is probably coming very soon!
