Extra features include a story mode during which the player plays as multiple characters, a Fatality training mode (allowing players to practice executing finishing moves), the Challenge Tower, tag team fighting, and an online mode. The Challenge Tower mode is a single-player option that includes 300 specific challenges of various difficulties providing currency rewards upon completion; players have the option of using in-game currency to bypass other difficult challenges, completing them later. Among the various challenges are "Test Your Might" (rapidly pressing buttons and using specific timing to destroy blocks of varying difficulty), "Test Your Sight" (following an object hidden under a cup or skull and revealing the object after a shuffle), "Test Your Strike" (destroying a specific block in a stack) and "Test Your Luck" (fighting under certain conditions, such as no jumping ). The four-player tag-team feature is an original feature, allowing two players to play together. During tag gameplay, two new types of attacks become available. The first of them is the "tag assist" attack, in which the off-screen character temporarily jumps in and performs certain attacks during the active character's combo. The other is the "tag kombo", in which the active character performs a combo that is finished by the off-screen character as they enter the fight.
