Shovel Knight Showdown (formerly known as Battle Mode) is an upcoming content for Shovel Knight: Treasure Trove. Since it is planned as local multiplayer only it will not be appearing on the 3DS or PS Vita versions of the game. Shovel Knight Showdown is also planned to be released as a stand alone alongside the campaigns.

The mode was officially revealed on August 28th on the IGN website and YouTube channel, as well as on Yachtclub Games' website.
