The final campaign, King of Cards, will launch in early 2018 and there will be new Shovel Knight series amiibo!
Spoilored for massive.
Shovel Knight: King of Cards is the last campaign in the Shovel Knight: Treasure Trove saga and is sure to become the crown jewel of the series. Players shoulder bash, spin jump and swing their scepter as King Knight to greedily conquer bite-sized levels over four new worlds. In between stages, players demonstrate their strategic genius by competing against other knights in a new card game. By tapping three new amiibo figures* based on King Knight, Plague Knight and Specter Knight while playing Shovel Knight, players can unlock exclusive armor sets, new challenge stages and the ability to summon fairy companions to accompany players on quests. Shovel Knight: King of Cards launches on Nintendo Switch in early 2018. The launch date for the new amiibo will be announced in the future.
I will surprised if they release King of Cards on Wii U. I would not be surprised if they ditched it, but I definitely would not be adverse to buying another copy of the game just to get access to it. It's that damn good.
