It hasn't been released on any platform yet. Yacht Club is still designing it.

thanks. king knight's picture was on the design for shovel knight: treasure trove. that way i thought there was a way to get him...

besides... i still have hard mode for ALL THREE campaigns. i beat all 3 once is what that means just in case u don't know.

Don't worry, he's coming. Knowing Yacht Club, they won't release his campaign until it's perfect, but they had said in one of their articles for Specter of Torment that they were hoping to release both King Knight and Battle Mode later this year.

i know! i read that. its just that i thought they perfected it early since king knight was on the icon, too.
