History VideoGame / Cytus

* ShowDontTell: Unlike the other stories, ''Knight'' doesn't really have a lot of text to describe what's happening; much of the story is left to fan interpretation.

* AfterTheEnd: In Timeline, [[spoiler:Taiwan is shown to be recovering two centuries after the earthquake and nuclear disaster of 2059, with plants covering long-abandoned-and-later-repurposed 21st-century buildings.]]

* GodzillaThreshold: Operators, effectively [[BrainUploading robots with human minds uploaded into them]], were met with wide backlash at first due to the moral and ethical questions surrounding them, but when a mysterious virus threatens to wipe out humanity, global health organizations and governments authorize use of Operators if it means preserving humanity, though of course they still have worrying questions about the concept of digital immortality.

* ZeroEffortBoss: The title track of chapter X, ''The New World'', is very long and has all of ''one'' note at the end. Subverted, in that although you just need that one Perfect to get the Million Master rank, it is just as easy to fail by mistiming or missing that note.[[note]]Getting a Perfect yields the full 1 million points, but getting a Good will only get you 630,000 points, which is 70,000 points shy of the clear requirement. A Bad will get you 270,000 points, and a Miss will result in a [[EpicFail zero score for the entire song]].[[/note]]

** ''Cytus 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 andrfoids.

** For whatever reason, hidden charts with a "swipe across the eyecatch" requirement (both alternate versions of "Slit" and "FREEDOM D↓VE", for example) are a lot more difficult to do in ''α'' than in the original smart-device versions.

* GameBreakingBug: The game has sync issues on certain devices. As many rhythm game players know, having the song be out of sync with the chart is very, very ''bad.'' Fortunately, an update allows players to calibrate timing offsets.

* {{Nerf}}: Chapter L had its charts reduced in difficulty in response to player complaints. However, the original charts are still available via {{Easter Egg}}s.

* EarnYourFun: ''α'' starts you with only Chapter 1 and the ''DJMAX'' chapter and requires you to unlock the other chapters, unlike the original smart-device version where (as of the end of the million-downloads campaign) all the main chapters, S, and K are available immediately with the rest as DLC. Specifically, the mainline chapters each require you to get a target number of total high score in the previous chapter, while the branch-off chapters require you to clear a set number of songs in the root chapter or achieve a set number of wins in online matchmaking mode.

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. Instead of chapters being DLC, each has to be unlocked by fulfilling certain conditions in a prior chapter.

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

** ''α'' averts this; instead, all chapters besides Chapter 1 and ''DJMAX'' have to be unlocked by fulfilling specific in-game conditions. It's also notably more expensive than the smartphone versions with all DLC, at 49.99 USD.

** The hidden songs don't have their names shown. They ''do'' have official names[[note]]usually just "Ver.B" or "II" tacked on at the end, but sometimes longer; for example, the two hidden songs on the splash screen for "Entrance" make up the "Precipitation at the Entrance" series[[/note]], but you'll have to look at soundtracks or their artist's websites to learn them, or use the Website/{{Twitter}} and Website/{{Facebook}} share buttons (until an update turned sharing into just posting screenshots). ''α'' on the other hand does show the hidden tracks' titles plainly when you play them

** ''Cytus α'' has a ''VideoGame/{{DJMAX}}'' chapter. Notably, one of the tracks in it, "Super Sonic", is from ''VideoGame/S4League'', making it a double example.

** The beginning of [[VideoGame/{{DJMAX}} "Super Sonic"]] on Hard has drag notes spell out [[VideoGame/S4League "S4"]] at the start of the chart.

** ''α'' averts this; instead, all chapters besides Chapter 1 and ''DJMAX'' have to be unlocked by fulfilling specific conditions. It's also notably more expensive than the smartphone versions with all DLC, at 49.99 USD.

* EarnYourFun: ''α'' starts you with only Chapter 1 and the ''DJMAX'' chapter and requires you to unlock the other chapters, unlike the original smart-device version where (as of the end of the million-downloads campaign) all the main chapters, S, and K are available immediately with the rest as DLC.

* DownloadableContent: Chapters Retro, Prologue, Timeline, VideoGame/{{Deemo}} and Nightkeepers are all separate purchases, at 4.99 USD each. The ''L'' chapter notably costs 9.99 instead, double that of the other DLC chapters. The entire package totals up to 36.93 USD, including the initial game purchase. While the Million Download plan was still in progress, this temporarily applied to chapters V through K as well.

** ''Cytus α'' on Switch. It features a new visual interface, an online multiplayer versus mode, new tracks including from ''VideoGame/{{DJMAX}}'' and the scrapped ''Cytus Omega'', among other things. Unlike other versions of the game, it costs as much as many retail games at 49.99 USD, and everything other than Chapter 1 and the ''DJMAX'' chapter have to be unlocked by playing songs, racking up total high score, or defeating online opponents.

* UpdatedRerelease: ''Cytus Lambda'' for the Vita. For a single purchase, it includes all Chapters from the get-go, with bonus chapters as free updates, as well as Chapter: Prologue, which at the time of release was Vita-exclusive. Unfortunately, it got the axe along with the [=PlayStation Mobile=] service in 2015, meaning Retro, Timeline, and Deemo are not included and the game is no longer available for purchase.

* TrueFinalBoss: Chapter R lists "conflict([=YM2151=] edit)" as the last track in it. [[spoiler:The [[SecretLevel hidden track]] of the chapter is unlocked on this chapter's splash screen; said hidden track is the original "conflict".]]

* {{Crossover}}: One with Rayark's second rhythm game, VideoGame/{{Deemo}} in the form of Chapter D. Deemo got many songs from Cytus in return, including all of Chapter K and Chapter L.

** The hidden songs don't have their names shown. They ''do'' have official names[[note]]usually just "Ver.B" or "II" tacked on at the end, but sometimes longer; for example, the two hidden songs on the splash screen for "Entrance" make up the "Precipitation at the Entrance" series[[/note]], but you'll have to look at soundtracks or their artist's websites to learn them, or use the Website/{{Twitter}} and Website/{{Facebook}} share buttons.

* KaizoTrap: While the pass conditions are lenient enough that you will very unlikely get screwed over from blundering the last few notes, this trope is still in force if you're trying for a full combo, Million Master, or 100 TP run:

** Thought "FREEDOM [=DiVE=]" was sadistic enough? Meet "FREEDOM D↓VE" (yes, with a down arrow), a SecretLevel accessed by swiping down on the former song's eyecatch at the song select screen that has ''2,000 notes'' in its Hard chart. Don't break your device's screen!
