Shovel Knight: King of Cards is the fourth and final game in the Shovel Knight series of platforming games, released on December 10, 2019.
Story
In a land of magic and adventurers, there is peace. And under peace, new pastimes have flourished. In particular, a card game called Joustus has rose to fame and with it, word of a grand tournament. Whoever can defeat the three judges shall be declared the King of Cards. The would-be king, King Knight, sees this as his chance to achieve his dream and become royalty. The journey for card supremacy has begun...
Gameplay
King Knight, unlike the other characters who have an array of movement options, only has one which can lead into a few different things. King Knight can perform a shoulder charge that, when it hits an enemy or part of the level, leads into a leaping pirouette that can bounce off of enemies and blocks. Upon bouncing off an enemy or block at least once, you can then perform another shoulder charge. The shoulder charge can also be cancelled into a roll, which does not launch you into the air.
This game brings back the world map from Plague of Shadows, and Shovel of Hope. Instead of the Armour Outpost or the Village, King Knight has the Glidewing, an airship that carries him and his companions to their destinations. From here, you can purchase items (this time called Heirlooms), new armours, and gain new abilities.
The world map also has the Houses of Joustus, where you can play the card game that they're named for. However, all the games of Joustus are completely optional, unless you want some extra gold.
While Spectre of Torment has a darker tone, King of Cards is significantly more light-hearted.
