[1] An arcade version titled Cytus: Omega in collaboration with Capcom was revealed at JAEPO in February 2015[2] and was set for location testing in July 2015,[3] but was ultimately canceled on 30 March 2018.

[8] The player must tap circular objects, known as Notes, as the Active Scan Line passes over them, following the music.

Cytus II has three to six difficult levels—Easy, Hard, Chaos, Glitch, Crash, and Dream—with difficulty ratings ranging from 1 to 15.

Later, she determined that she was one of person who entered memory transfer services powered by ExtenLife to extend their life and live with her loved ones.

While traveling, she found the cyro-pods that store the living humans who survived the alien virus by freezing themselves into the pods.

As more and more people used the virtual internet, more and more musicians held concerts on iM, a social networking service.

By browsing through iM and each character's private "OS logs", players can unlock new songs and gain insight into the story of Cytus.

Later, Paff and her media company, Monophonic Entertainment, announced the date for her annual event, PAFFCON.

Neko was arrested by Node 08's Administration Bureau because she was suspected of launching a widespread attack on her fans.

The lead singer of Crystal Punk, Cherry, was inadvertently injured while entering the building's headquarters.

Years earlier, her career started through a talent show at her school where the winner would sign a contract with an entertainment company.

Unknown to the other characters, an Architect, or an intelligent AI android that assisted with the reconstruction of human society, attacked Neko's stream and iM.

Ivy finally woke Vanessa up through OS space, a space in Cytus where people can meet and interact; however, because of a video that another Architect, Ilka, showed her before the Decommission, Vanessa's core was corrupted, changing her from thinking about helping with humanity to finding a way to end humanity.

As a safety measure, Ivy sets up a firewall in an attempt to prevent Vanessa from hacking or compromising any other Internet-connected devices.

Nora had used this ability before, but it left her vision trapped in OS space, leaving her unable to see in the real world without technology.

At one point, when entering OS space, Paff encounters Vanessa and discovers her intent to eradicate humanity.

While backup power can reenergize lights and doors, the life support Cherry is on fails, and she dies.

Noah attempts to disrupt Vanessa's signals by sending an electric shock to damage the robots, electrocuting himself in the process.

Armed Forces find Ivy and kill her, forcing Paff, Neko, Nora, Xenon, ConneR, Robo Head, and the player into a final battle to inject a virus that they created earlier through OS space into Vanessa, ultimately killing her and restoring the peace that precedes.

During the final battle, Paff calls out to the player for help sharing the burden of the virus in OS space.

Joe rebuilds his cafe that was destroyed in a drone attack, Neko gives up from game streamer to walking in a musician career path and finds the foundation to help victims in Vanessa events, Xenon's sister is successfully recovered from OS space, and the world bring back into a peace without Vanessa.

But it causes you to fall into a coma for a long time and your consciousness is still driving into the OS space for 10 years (since the release of the first Cytus game).

PAFF and Vanessa told to players that the future is in our hands and we can change it, and it will be a "new beginning" of Cytus's world.

But when she starts to go live from the memorial to the victims in Node 08, Vicky's interview is interrupted by protesters to publicize their broadcast in iM to show the darkest side of A.R.C, the Cytus, and the Architects.

In the credits roll, E00200 will see that the people who watched the broadcast are also talking about this topic until one message that E00200 received "What will you choose..?".

[14] This version, along with a revamped interface, added two new chapters, extra story elements, and an online Battle Score mode.

[18][19] As of April 2021[update], Cytus ranks #8 in the iOS App Store's "Music" category in the United States.

Ryan Craddock of Nintendo Life gave the game a "great" 8 out of 10, praising the game's mechanics as "something particularly satisfying about dancing around the screen playing a musical version of whack-a-mole", but that its higher price compared to Rayark's other titles Deemo and Voez meant that "Rayark has almost shot itself in the foot with its previous releases.

[25] Multiple Cytus soundtracks have been released both on iTunes and as physical CDs, featuring playable music and background composition from the game.

[30] The Cytus II soundtrack consists of music by indie composers from the United States, Japan, South Korea, and Taiwan.
