Extra Mode is a special mode of play found in Mungyodance 2 and Mungyodance 3: The Third Rave. It allows players to play through songs with scripted modifiers designed for the song. It is powered by the system in StepMania originally made for Nonstop courses.
In Mungyodance 2, a screen with a large banner in the center, a speed modifier selector, and a difficulty value display is shown in Extra Mode. Songs that haven't been unlocked yet that have Extra Mode modsets can be played in Extra Mode.
