Shovel Knight Showdown (formerly known as Battle Mode) is the fifth game in Shovel Knight: Treasure Trove. Since it's only local multiplayer, it is not on the 3DS or PS Vita versions of the game. Shovel Knight Showdown can be also purchased as a stand-alone game.

Shovel Knight Showdown is a platforming fighting game with 20 characters from the Shovel Knight series. There can be up to 4 players (normally) in matches and there are a variety of modes to choose from. All 4 playable characters: Shovel Knight, Plague Knight, Specter Knight and King Knight have the move set from their campaigns translated into Showdown. Other characters get their own new move set, usually catering specifically for Showdown. There is also a unique parry move, where you can block incoming attacks.
