Yacht Club Games has promised that 2016 will be big for Shovel Knight, as they plan to finish up all the game's content by the end of the year. This content includes two more playable campaigns—one for Specter Knight and one for King Knight. No information about when these campaigns will be released is available yet, though Yacht Club Games is working on both simultaneously in order to reduce the wait. We do have a small bit of footage from the King Knight campaign, however.
It's not much, but what is there looks pretty great! Check out the small clip below!
