Up, and was developed separately from the main series with the intent of getting players who normally play 4-panel dance games to try 5-panel dancing. The game utilizes a heavily modified build of StepMania 4 for its engine and was purchasable as a cabinet or as an upgrade for existing Pump It Up machines running MK6 or MK7 hardware.
