Out of the sewers and into the streets, the rightful King of the Rats is here at last. Rodent-hating citizens of Manhattan won't be prepared to see his Scrap Grenade bouncing down Broadway, nor for his Swarm of Rats biting at their heels. By donning his Royal Pestments, the Rat King shakes off incoming damage, allowing him to bravely lead the charge into battle. His loyal subjects will feel awed and inspired when they see the great Banner of Rattania waving in the middle of combat, and those who oppose him will rue the day they ever thought they could overthrow the king. - "Oh the rats are taking over, baby!"

The Rat King is available to play now! Have a great weekend and keep those votes coming, as our next hero will be joining us on Tuesday at 2pm PDT. We'll see you then!
