It’s almost time to dig up their buried copies of Shovel Knight. The platformer’s free Plague of Shadows update will release for all platforms and regions on Thursday, September 17, developer Yacht Club Games has announced.

Shovel Knight: Plague of Shadows puts players in control of Plague Knight, the alchemist foe from the original release, in an altered version of the game’s main quest. Plague Knight has his own unique set of abilities (bomb jumps, explosives and alchemy) that differ from protagonist Shovel Knight’s, but he doesn’t posses the titular shovel that Shovel Knight uses to bounce on enemies, which meant Yacht Club had to rearrange some level design components. But the developer didn’t stop there: it also added in entirely new areas and bosses. Finally, the new Challenge Mode will task gamers to complete speed runs, boss rematches and more.

In XBLA Fans’ review, Jill Randolph awarded the game a “Buy It” score, noting that “Shovel Knight will try your patience from the start, but it will also suck you in and provide hours of quality gaming.”
