Cytus Wiki
Cytus II Banner

The interconnected internet platforms have become more substantial than any country or corporation. Humans have redefined the “net” and how we interact with it.

As technology develops, the virtual world is now capable of replacing the real one. Using a device installed behind the ear, humans can now easily sync to the virtual world.

Thus, life is now completely different than the past centuries. The center of this change is the virtual internet space –- cyTus, the world’s largest virtual city.

In the real world, it is a giant server located in the stratosphere and powered by solar energy. In the virtual world, it’s a place where 70% of the Earth’s population is living their second life.

In the future, humans have redefined internet development and connections. We can now easily sync the real world with the internet world, changing life as we have known for thousands of years.
In the mega virtual internet space cyTus, there exists a mysterious DJ legend Æsir. His music has an irresistible charm; people fall madly in love with his music. Rumor has it that every note and beat of his music hits the audiences in the depths of their souls.

One day, Æsir, who had never shown his face before, suddenly announced that he will be holding the first mega virtual concert —— Æsir-FEST and will invite a top idol singer and a popular DJ as opening performances. The instant the ticket sales began, an unprecedented rush occurred. Everyone wanted to see Æsir's real face.

On the day of the FEST, millions of people were connected to the event. At one hour before the event started, the previous world record for most simultaneous connection was smashed. The whole city was on its feet, waiting for Æsir to descend from the skies...

Game Features[]


Cytus II uses the same mechanics from Cytus, including Click, Drag, and Hold notes. However, three brand new types of notes were introduced: Flick Notes, Special Hold Notes, and Click Drag Notes, as well as Tap and Slide notes from Deemo in certain difficulties. The player has to follow the notes on the white scan line that goes up and down the screen. The scan line can now increase or decrease its speed midway according to the beat, allowing for a more unique experience. Hitting the notes will increase score and, if accurately so, Technical Points.

Songs and Artists[]

Cytus II includes songs by composers from all across the world, Japan, Korea, the US, Europe, Taiwan and more. Through the characters, players get to play songs from different genres including pop, electronic, hardcore, art-core, punk rock, ethnic, rock, classical, pop punk, jazz, Arabian and oriental.

Cytus II currently has 567 songs from various artists. Songs can be accessed by selecting different characters, each with a unique music style, or bought through the Black Market function.

Level System[]

Every character in Cytus II has a level system to unlock new story messages, songs, and difficulties.

Dependent on performance in a particular song experience is rewarded.

Additional experience is given when completing a chart for the first time.


Cytus II has seven difficulty levels: EASY, HARD, CHAOS, GLITCH, CRASH, DREAM, and DROP with the later five being newly introduced in the game franchise. With dozens of different charts currently featured in the game, the rich array of content suits players of different skill levels, allowing them to experience exciting challenges and enjoyment. CHAOS, GLITCH, CRASH!, DREAM, and DROP are difficulties which introduce new game mechanics apart from the ordinary ones and are more difficult in general. These seven difficulties are general classifications for each chart and are further defined by a 1 - 15 numerical system, except CRASH!, which uses Greek Letters.

More information about the difficulty systems can be found here.

  • Chaos: Flick notes, infrequent multi-finger gameplay, and Click-drag notes.
  • Glitch: Teleporting scanline, frequent multi finger gameplay and complex note patterns.
  • CRASH!: Frequent three finger gameplay, up to nine simultaneous hold notes, half scanline, invisible scanlines, and incredibly complex note patters.
  • Dream: Gameplay switches between Deemo and Cytus; Piano mode features tap piano notes and drag piano notes. Charts are a combination of the Deemo Chart and the Cytus Chart.
  • Drop: Gameplay switches between Deemo II and Cytus; Piano mode features tap piano notes and drag piano notes. Charts are a combination of the Deemo II Chart and the Cytus Chart.
  • Easy: 1 - 6
  • Hard: 4 - 10
  • Chaos: 8 - 15
  • Glitch: 12 - 15
  • CRASH: a, β, and γ.
  • Dream: 8-15
  • Drop: 11-15
    • It has been argued by the community that the numerical system should be expanded beyond 15, as with the introduction of the Glitch difficulty the actual difficulty of level 15 charts varies wildly.
