Beatmania IIDX 13: Distorted is the 13th game in the Beatmania IIDX series of music video games. It was released in arcades by Konami on October 19, 2005. It was Last Series before Konami Digital Entertainment. The game features a total of 55 new songs, some of which are unlocked over Konami's e-Amusement platform. Distorted's interface is a refresh of Happy Sky's interface, but using a monotone color scheme with orange wireframe patterns in menu backgrounds.
Of note, Distorted was the first arcade version of IIDX to be officially exhibited in North America, making an appearance at E3 2006 alongside GuitarFreaks V2 in response to low sales of the US PS2 version and the debut of a sequel to a game which overshadowed its release, Guitar Hero II. An English build of the next version was ultimately beta tested but not officially released.
Gameplay[]
Beatmania IIDX tasks the player with performing songs through a controller consisting of seven key buttons and a scratchable turntable. Hitting the notes with strong timing increases the score and groove gauge bar, allowing the player to finish the stage. Failing to do so depletes the gauge until it is empty, abruptly ending the song.
The core gameplay remains the same in Distorted, but with several minor additions, such as the ability to change the High Speed setting used in-song by holding down the start button. Double and 2-player notecharts can now be flipped (so that the 1P side would be on the 2P side instead and vice versa). In addition, High Speed 4.5 and 5.0 options have been added.
Also, in Class mode, this version introduces a new grade called "Kaiden", designed for the most skilled, most consistent players in the world. It consists of four out of the most difficult songs available in the version.
