Tower-defence sequel Kingdom Rush: Frontiers just got a bit creepier, courtesy of the Halloween-themed Shadowmoon campaign update.
If battling scorpions and sandpeople wasn't already tough enough, anyone who downloads the free update will find themselves fending off waves supernatural nasties.
Vampires, werewolves, ghosts - all of these evils are about to be unleashed upon your armaments.
Luckily for you, the also update provides you with two new heroes to call upon.
You can now choose between vampire hunter Dante, or Dracolich expert Bonehart, both of whom are a dab hand at dealing with the forces of darkness.
In addition to the new troops, you'll get three new Halloween levels to tackle, and a bunch of new achievements too.
What's more, the game - and the in-app purchases contained therein - is currently available at 66% off the usual asking price.
We were big fans of Kingdom Rush: Frontiers refined take on the tower defence genre. So, if you're interested in keeping the footsoldiers of Satan at bay for a reasonable price, now's the time to get on board.
