Cytus Android

[Alacoque Whitchurch]

Thegameplay of Cytus relies on Active Scan Line, which moves up and down across the screen.[8] The player must tap circular objects, known as Notes, as the Active Scan Line passes over them, following the music. Different types of notes are used: Click Note (a single circular note, that requires tapping the object in time), Drag Note (a continuous track of notes, that requires dragging along the track), and Hold Note (has an extended ribbon meter, requires the note to be held until the meter is filled).

The notes to be hit as the line rises are colored blue and purple (light green in Cytus II), while those as the line falls are colored yellow and green (light blue in Cytus II).[8] Each note provides a score based on its accuracy, which can be "Perfect", "Good", "Bad" or "Miss!". Hitting consecutive notes in a row with either a "Good" or "Perfect" rating will result in a combo, which provides a score boost that increases as the combo rises. At the end of a song, the player is given a score out of 1,000,000, with a minimum of 700,000 required to clear it.[8] The player also receives a letter grade: "Fail" if a song isn't cleared, C at 700,000 points, B at 800,000 points, A at 900,000 points, S at 950,000 points, and Million Master at the maximum 1,000,000.

There is a secondary scoring system, "Technical Points" or "TP". This introduced a new, stricter rating known as a "Rainbow Perfect"[citation needed] denoted by a rainbow outline on the disappearing note effect. TP is calculated purely on note accuracy and is given as a percentage.

The story of Cytus is carried through its 10 main chapters as well as a prologue.[9] The story is told in-game through various cutscenes that are unique to the chapter title songs; individual songs within each chapter are at most only marginally relevant to the plot, except for a limited few. The plot features the disaster and the protagonist's struggle with identity.[9]

The story revolves around the protagonist, Vanessa, who lives in a 22nd-century world where robots with human memories are the only things remaining. While the other living humans are killed by a mutant alien virus that came from outer space. 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. The transfer is interrupted due to limited memory space and her emotions are corrupted. As human emotions are stored in the form of music in "Cytus", by playing the songs, the robots can revive their human emotions. When she revives it, she is sad about it. She tries to write a mini program with Lua to delete her emotions from their memory and starts to travel around the node to delete the emotions from the other robots called "The Operators". While traveling, she found the cyro-pods that store the living humans who survived the alien virus by freezing themselves into the pods. Vanessa tries to awaken the freezing humans and give them a mission to rebuild human society again.

Cytus II, the sequel to Cytus, takes place about seven hundred years after the establishment of the new human society called "The New Age (N.A.)" (as the ending of Cytus). And established A.R.C. to create a virtual Internet space called Cytus (stylized as cyTus). As more and more people used the virtual internet, more and more musicians held concerts on iM, a social networking service. One musician, Aesir (stylized as sir), decided to hold a large virtual concert in Node 08, one of the many nodes in Cytus. Attendees of the event included Paff (stylized as PAFF), a popular singer, Neko Asakura (stylized as NEKO#ΦωΦ), a famous streamer on iM, and Robo Head (stylized as ROBO_Head), an AI robot. A bunch of top musicians performed, but the organizer, Aesir, was nowhere to be seen, even after the end of the event. 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. Tickets for her event sold out quickly. At the event, while Paff was performing Gravity, a song that she performed in Aesir Fest, she collapsed and was sent to the hospital, where she woke up a few days later and started recovering.

While Paff was in the hospital, one of Neko's streams got hacked and DDoS attacked by Aesir. Neko was arrested by Node 08's Administration Bureau because she was suspected of launching a widespread attack on her fans. Meanwhile, Robo Head later discovers that his memory of Aesir was corrupted, and starts data recovery. People wanted to know who was responsible for the hacking. After Robo Head completes data recovery, he learns that Aesir did show up at the event and that they wiped everyone's memory of Aesir after he finished performing, and this is the same attack method on the Neko hacked streams.

Soon after, a new band, Crystal Punk, created their new account and hosted their first major event. Paff was originally going to attend, but her health did not improve. Neko was acquitted a few weeks later by the Administration Bureau. Paff left the hospital and was reported missing by Monophonic Entertainment. Her real identity, Aroma White, was also released by the company. This sparked protests outside of Monophonic's headquarters regarding the location of Paff. The lead singer of Crystal Punk, Cherry, was inadvertently injured while entering the building's headquarters. Cherry was discharged from the hospital a few days later.

Not long after, the entire iM system was being affected by a data corruption bug. Eventually, iM was attacked by Aesir, preventing anyone from logging in and scrambling messages so readers could not see them. The attack led to Xenon (real name: Simon Jackson) being arrested on charges of doing everything that Aesir did: delete memories and attack the virtual Internet. Xenon pleads no contest to these charges, and he is sent to prison.

After Paff is located by her sister, Helena, Paff discovers that she has the memories of two people: Aroma White and Kaori Minamiya. Years earlier, her career started through a talent show at her school where the winner would sign a contract with an entertainment company. On the way to one of her events, she was seriously injured in a car accident. Aroma was sent to the hospital in critical condition. Noah, Helena's husband, was able to save Aroma by transplanting her memories into that of another body, Kaori. Through that, Paff could sing songs none of her family heard of, but she could not remember before the car accident. Paff goes to Node 03 along with Neko and Hayato, a reporter, to learn more about her past.

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. Architects also can feel emotions that humans can feel. Ivy (serial number: OPCI_2501_IV) was attempting to wake another Architect, Vanessa (serial number: OPCI_2501_V), through the Cytus platform. Ivy woke up 500 years after "the decommission", or when Architect robots were deactivated after human society was recovered from the "Ender Virus" (also known as Alien Virus from Cytus). She needed to collect memories of Ivy and Vanessa in order to wake her up. 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. Ivy wants to find a way to save Vanessa.

After Ivy establishes contact with Vanessa, she encounters and captures Noah and asks him to transfer Vanessa's memories to that of an empty Architect unit to attempt to wake her up. Noah is unsuccessful and injured, and the empty unit is damaged beyond repair. As a safety measure, Ivy sets up a firewall in an attempt to prevent Vanessa from hacking or compromising any other Internet-connected devices.

Meanwhile, two members of Crystal Punk, Cherry and ConneR, break Xenon out of jail. In Node 03, Paff and Neko encountered Robo Head and met Nora. Nora is the leader of Kyuu Hou Hai, one of many gangs that prevail in Node 03. Nora explained to Paff that she has the ability to see into OS space. 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. Kyuu Hou Hai was attacked a few days later by drones. The group successfully fights off the drones, but Cherry gets shot in the process. These same drone attacks also destroyed Joe's cafe.

Cherry was placed on life support in Kyuu Hou Hai. Nora guaranteed that she would recover successfully; however, the electricity at Kyuu Hou Hai blacks out. While backup power can reenergize lights and doors, the life support Cherry is on fails, and she dies. The band she created is disbanded as none of the other members knew how to sing well.

After a successful investigation in Node 13, ConneR determined that Ivy was likely the culprit of the drone attacks. He, Nora, and the rest of the group return to Node 08 to stop the destruction of humanity. After encountering Ivy at A.R.C., a technology company, they learn that Vanessa is causing the chaos. Soon after, Vanessa hacks the weather system and reprograms it to extreme weather to spread a virus, triggering the end of humanity. Noah attempts to disrupt Vanessa's signals by sending an electric shock to damage the robots, electrocuting himself in the process. Ivy successfully goes into the Library at A.R.C. and successfully encounters Vanessa following the advice of another Architect, Rin, to talk to her calmly to snap Vanessa out of the attitude of desiring to destroy humanity. Not long after, the A.R.C. 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. But they fail to kill Vanessa, causing her to release the virus, which wipes out all of humanity except the players and Paff, who are immunization to the Ender Virus, and traps them into OS Space forever, and brings back the beautiful world.
