Shovel Knight was revealed earlier this week as an assist trophy for Super Smash Bros. Ultimate. For those hoping to play as the character himself, though, Rivals of Aether announced that he would join their game soon as a premium DLC.

This makes 21 appearances for Shovel Knight in games not named Shovel Knight, and 14 of them are playable. Dan Fornace llc (makers of Rivals of Aether) and Yacht Club Games (creators of Shovel Knight) announced the premium DLC today. It costs $4.99 and will come with a Troupple Pond stage from his 2014 game.
