Shovel Knight’s first DLC expansion, Plague of Shadows, will be released next week, developer Yacht Club Games has announced.

Plague of Shadows will release on September 17th on all platforms. The DLC adds a new Challenge mode, as well as a new playable character, Plague Knight. The expansion also adds new objectives, enemies, areas, paths, feats, and bosses. The story has been modified, and Plague Knight uses explosions and bomb jumps as a way of getting around.

Plague of Shadows will be free. The DLC expansion has been in the works for some time, and was a stretch goal during the Shovel Knight Kickstarter campaign. Plague Knight is the first of the game’s bosses to be turned into a playable character.

To play as Plague Knight, you will first have to complete the base game as Shovel Knight. If you want to jump into the game as Plague Knight right away, Yacht Club has said that they will release a code that unlocks the character right away.

Shovel Knight is available on PC, Nintendo 3DS, Wii U, PlayStation 3, PlayStation 4, PlayStation Vita, and Xbox One. Plague Knight is not the first extra character in Shovel Knight. Other guest characters have included God of War’s Kratos and the Battletoads.
