Cytus is a mobile rhythm game developed by Rayark Games. The gameplay is similar to DJMax Technika and osu. Weeks ago, Cytus official page posted a picture with “Chapter K” title on it, which also indicates that Chapter K will be updated in the near future.
As we know, Cytus had a “Million Download Plan”, for every 100,000 downloads they will release a new chapter. Cytus has completed five hundred thousand million downloads target in early March of this year.
Some official sources said that Chapter K, will feature Holy Knight related songs (maybe their style will be similar to it). But we must wait for their complete announcement for more detailed track and more info.
