Beatmania IIDX 4th Style

In IIDX games, players recreate the musical score of songs available to them through the use of a DJ simulating controller. The player must coordinate their hands in order to hit the correct keyboard buttons, spin the turntable, or a combination of both in correspondence to color coded notes that approach the judgement bar displayed on screen.
