Yacht Club Games has tweeted a note saying that the last campaign of the Shovel Knight Treasure Trove Saga, King of Cards, has entered the alpha.

King of Cards promises to be bigger and grander than all the campaigns before with all new levels, card battles, and multiple worlds. The game is also on track for release on the Switch and 3DS in the second half of this year.

Happy to share we have reached "alpha" on Shovel Knight: King of Cards!

King Knight's quest is big! All new levels, card battles, multiple worlds… and we played it all from start to finish!
