History VideoGame / Cytus

''[[http://www.rayark.com/g/cytus/ Cytus]]'' is a RhythmGame developed for [[UsefulNotes/IOSGames iOS]], UsefulNotes/{{Android|Games}}, UsefulNotes/PSVita[[note]]Although the Vita version has been more or less discontinued with the closure of the [=PlayStation Mobile=] service[[/note]] and UsefulNotes/NintendoSwitch by Rayark.

An UpdatedRerelease of the original game by [=FlyhighWorks=], ''Cytus α'', was released for UsefulNotes/NintendoSwitch in digital format on April 25, 2019, and in physical format in Japan on the same day with the North American version to follow on May 14 and the European/Australian version to come at a future undetermined date. ''α'' includes the option to play with buttons (much like on ''VideoGame/{{VOEZ}}'' and ''VideoGame/{{Deemo}}'' on Switch, also Rayark games ported by FHW), an online matchmaking versus feature, an updated visual interface, and new songs including a ''VideoGame/{{DJMAX}}'' crossover chapter and an ''Omega'' chapter that includes songs from the cancelled ''Cytus OMEGA''. Instead of chapters being DLC, each has to be unlocked by fulfilling certain conditions in a prior chapter.

* BonusBoss: All secret songs (except "Saika ver.B") are level 9 on Hard. "Conflict" and "L2 ver.B" especially stand out in difficulty.
** ''Freedom Dive'' has a bonus chart from version 10 onward, accessed by swiping down over the title.

* DifficultySpike: As befitting of a chapter based on three noticably difficult tracks from Chapter VII, the whole of the chapter features fiendishly hard charts even by the standards of level 9 charts. In fact, the original charts are all rated level 9, even on Easy, and they are so difficult that Rayark released an update with easier sets of charts.

* YouGottaHaveBlueHair: Iris and Meteor from Chapter K and L, respectively. Several songs have characters on their artwork who qualify as well.

** ''Alive'' is the main story of the game, featuring a world where humanity has been wiped out by a virus and people undergoing voluntary BrainUploading to live on as androids.
** ''Knight'' is based off of the eyecatch for the Chapter V track "Holy Knight", and shows two childhood best friends becoming separated, with one becoming a knight and the other becoming the queen of a rivaling nation, with tragic results.
** ''Timeline'', composed by the [[https://vgo-online.com/ Video Game Orchestra]], tells the history of UsefulNotes/{{Taiwan}} and then continues into the future to tell a GreenAesop.
** ''L'' is based off of ICE's "L" series of existing tracks, including "L" and "L2" from Chapter VII, and is about a conflict between the heavens and Earth and two boys who end up caught in the big picture.

* ZettaiRyouiki: As a queen and the "Lord of Crimson Rose", Rosabell boasts Grade A.

* GreenAesop: In 2057 ("Protest"), the government of Taiwan, faced with a an energy crisis coupled with tech corporations' demand for energy, falls back onto nuclear energy rather than alternative sources, resulting in protests across the country. This leads to disaster two years later ("Catastrophe") when a major earthquake destroys the nuclear power plant and causes radioactive material to spread throughout the country, forcing mass evacuations from the capital city of Taipei. Eventually, natural fauna grows back after two centuries of human non-interference and nature is allowed to thrive in the area once again ("Rebirth").[[note]]It should be noted that nuclear energy is actually one of the ''cleanest'' forms of producing electricity. What happens when a nuclear power plant goes wrong, however, is a different story.[[/note]]

* FakeDifficulty: The original Hard charts have ''extremely'' slow scanlines, making it quite difficult to read the chart. This is because the tracks are actually very slow, each at less than 80 BPM; the scans are already running at double speed. The original Easy charts and the new charts are using ''quadruple''-speed timelines for readability.

** The "TP" system, which was implemented in repsonse to players complaining that the game's Perfect window is too wide. When you get a Perfect, you will get one of two different splashes: a Perfect with a green-and-orange splash, and a Perfect with a black splash; the former gives out more TP (100% of per-note TP) than the latter (70%). A Good will give out 30%, and anything less gives out 0%. TP is not combo-based, so where you make mistakes is irrelevant.

* TakeThat: "Phubbing" is a criticism of modern smartphone culture, discussing the phenomenon of people constantly being on their smartphones even when they're together with friends and family. Given that the game is primarily played on smart devices like Rayark's other games, it doubles as SelfDeprecation and a [[TakeThatAudience Take That to the player]].

* TimeAbyss: The two girls you see in every track's eyecatch? They're actually aliens who record the timeline of Taiwan, and do so for millions of years, everything from the Penglai Movement to the 23rd century AD and beyond.

* FaceHeelTurn: The Forbidden Codex did ''something'' to turn Rosabell into a malicious power-hungry monarch.

* {{Retraux}}: Chapter R: Retro, as the name suggests. It consists entirely of chiptunes[[note]]With one exception: the original version of "Conflict", which is a SecretLevel[[/note]]. Each song has a pixel art eyecatch.

** "Genesys" from the ''Million'' chapter shows Iris and Rosabell working together as detectives to solve a murder case, specifically that of VideoGame/{{Deemo}}.
