Shovel Knight: Plague of Shadows is the second campaign of Shovel Knight and a parallel story to Shovel of Hope. It stars the loony alchemist Plague Knight in his quest to craft the Ultimate Potion from the Essences of his fellow knights of the Order of No Quarter.
Originally, Plague of Shadows was playable only after either beating Shovel Knight's own campaign (later rebranded as Shovel of Hope), or by inserting a special input based cheat code in the title screen, but with the upgrade of the original release to the Treasure Trove compilation, this is no longer the case, and the cheat code has been completely disabled; currently, unlike the other campaigns and Shovel Knight Showdown, Plague of Shadows is the only game of Shovel Knight: Treasure Trove that lacks a standalone re-release, being instead only playable inside the compilation and not in any way present in the standalone release of Shovel of Hope.
