An [[AdventureGame Adventure]] VideoGame created by French studio Creator/QuanticDream. Yes, that's the one behind ''VideoGame/{{Fahrenheit}}'' and ''VideoGame/HeavyRain'', and is a game often forgotten to be mentioned in previews, reviews and discussions about ''Heavy Rain'' and Quantic Dream's work.

The plot concerns [[NoFourthWall you]], or more specifically, your soul. You buy a video game that allows your soul to enter another world; the eponymous city of Omikron.

Said city is a terrifying {{Dystopia}} where all human activity is planned by a monolithic super computer named Ix. Ultimately, the player finds out that the reason they are in the city is... well... not what they initially expected. The plot has players go from working for the government to working with a terrorist group to ultimately working their way though a GovernmentConspiracy that shows TheManBehindTheMan is quite horrifying.

A GenreBusting game that incorporates fighting, {{FPS}} and {{RPG}} elements alongside its adventure, Quantic Dream calls the game a [[{{Pun}} "Soul Playing Game."]]

Is now available DRM-free on [[http://www.gog.com/game/omikron_the_nomad_soul GOG.com]]

Also notable for featuring a soundtrack by Music/DavidBowie and regular Bowie collaborator Gabrel Reeves. Bowie also voices two characters in the game: the revolutionary philosopher Boz, and the lead singer for the subversive rock band, the Dreamers. As a result, following David Bowie's death, Square-Enix made the game available for free for a week in tribute.

!!This Game Contains Examples Of...

* AIIsACrapshoot: Ix, Omikron city's MasterComputer, is literally controlled by the BigBad, [[spoiler:Asteroth, ruler of Hell]].
* AnotherDimension
* BeneathTheEarth: You eventually find your way down to Omikron's spacious catacombs.
** AncientTomb
* BigBad / ManBehindTheMan: [[spoiler:Astaroth.]]
* BladderOfSteel: There is no pause function. Consulting your computer may look like you're pausing, but time continues ticking (and pedestrians and cars continue moving) while it's pulled up. And you can't even consult your computer during the fighting or FPS segments, or while you're swimming. (Granted, you could take a break by saving and shutting the game off--but if you don't have any [[SaveToken magic rings]], then you're completely out of luck.)
* BrainUploading: Boz, the philosophical leader of The Awakened, exists as a consciousness hiding in the master computer. [[spoiler:In the final cutscene, he plans to research how to get his body back.]]
* BureaucraticallyArrangedMarriage: Select Omikronian citizens, as explained by in-game documents, are paired together and wed by the government. Choices for would-be couples are based upon their physical and mental compatibility with one another to produce the best offspring.
* CallARabbitASmeerp: The ubiquitous wrist-mounted personal computers are called "sneaks", and taxi cabs are called "sliders".
* CityOfCanals: Lahoreh, one of the districts of Omikron.
* CoolSword: Barkaya'l, [[spoiler:which is empowered by the souls of all the ancient sorcerers of Omikron (minus one), and as such is the only weapon powerful enough to kill the BigBad.]]
* CutsceneIncompetence: [[spoiler:At the beginning, Kay'l asks you to take care of his body, but this is ultimately impossible. If you keep him alive all the way through the fight against Chief Gandhar, a random Meca will shoot him dead in a cutscene immediately after.]]
* CyberPunk: Omikron.
* DecoyProtagonist: [[spoiler:Kay'l. He's played up in promotional material as the main character, with the intro showing him involved in sequences that come long after his death.]]
* DialogueTree
* DomedHometown: Omikron, to protect it from an ice age that has engulfed the planet.
* DugTooDeep: [[spoiler:While digging the foundations of Ix's palace, the construction workers accidentally unearthed the cage where the BigBad was imprisoned, thus allowing it to extend its influence upon the world once again.]]
* {{Dystopia}}: Omikron.
* EverythingIsOnline: An odd usage where almost any physical object can be digitized and stored on a hard drive, so that your personal computer serves as your inventory.
* FightUnscene: [[spoiler:While the Nomad Soul fights Asteroth, the Awakened incite a revolution and successfully overthrow the whole Omikron government. You don't see any of that battle, and only get to hear about it after the fact.]]
* FirstPersonShooter: Some segments of the game are played as an FPS.
* FissionMailed: [[spoiler:The first two times you lose a fist-fight against a demon, you'll body-hop into a random passer-by, then the game will continue as normal. On the other hand, all of those fights are winnable--and oddly enough, after those two times, getting killed by a demon results in a regular Game Over instead.]]
* GovernmentConspiracy: [[spoiler:Omikron and every organization within it (apart from the terrorist group) are controlled by malevolent demons; the king of whom wants to torture your soul for eternity in order to fuel his attempt at mulitverse-conquest. The trusts, Ix and [[EvilChancellor Legatee Reshev]] are all their puppets.]]
* GrandTheftMe: A core game mechanic. Your "nomad soul" can inhabit and control the bodies of certain special people.
* HoistByHisOwnPetard: While imprisoned, you use this method to escape. [[spoiler:When the jailer attacks with an electric torture beam, you reflect it back at him with a metal bowl.]] Your character even {{lampshade|hanging}}s it in the dialogue immediately after.
* InventoryManagementPuzzle: You only have 18 total inventory slots on your person, which is often barely enough to carry all your weapons, mandatory quest items, and powerups. However, you do have access to dozens of stationary computer terminals throughout the world with limitless storage space; you'll be detouring a bunch to unload all those badges and keys you don't need anymore.
* IShallTauntYou: When you get captured, you escape your jailer by taunting him until he electrocutes you.
* IrrelevantImportance
* JustifiedSavePoint: Saving is accomplished preserving your soul at in-universe save points, using [[SaveToken magic rings]] [[spoiler:left behind by the Renegade Sorcerer]].
* LaResistance: The Awakened are the only ones who know the truth about Omikron's government and fight back against its tyranny.
* LastFertileRegion: Jahangir Park.
* MegaCorp: The government-linked trusts, Khonsu and Tetra. Fitting for the CyberPunk setting of Omikron.
* MinorCrimeRevealsMajorPlot: [[spoiler:Kay'l and his partner were investigating a serial killer who mauled their victims, only to begin to suspect that this murderer was no mere human... In fact, once it's figured out that it is actually a demon, this leads your character to uncover that Omikron is [[GovernmentConspiracy actually ruled by a shadow government controlled by evil demons]].]]
* TheMole: You and Jenna get captured after the Tetra factory mission because one of the other Awakened sold you out. When you escape, you have to snoop around to find the mole. [[spoiler:It's Namtar. Not only is secretly a member of the Omikron government, but he's a demon himself.]]
* NeverTrustATrailer: The AttractMode is styled like a movie trailer, but features some aliens that never appear in the game itself. [[spoiler:And to better hide that Kay'l is just the DecoyProtagonist, the trailer features him in scenes that come long after his mandatory death in the actual story.]]
* NoFourthWall: One of the earliest examples of this trope in video games. The game begins with a police officer from another world asking ''you'' to transfer your soul into his body. It only gets more demented from there.
* NoGearLevel: When you get captured by the government, they don't take away your computerized inventory--but they do lock it down, so you can't access any of your weapons or gear. A trip to the nearest computer terminal is enough to unlock your inventory and get everything back.
* OptionalSexualEncounter: Once near the start of the game. Kay'l's wife climbs into bed, and you can climb in with her.
* PamphletShelf
* PeaceAndLoveIncorporated: The Omikron government, which uses thought modifiers.
* PermanentlyMissableContent: [[spoiler:After Kay'l dies, you lose his ability to access most parts of the Security Headquarters. Everything necessary for the main quest is still open, but the optional missions and side content can be lost forever if you don't complete them before his death.]]
* ThePlace: The game is named for Omikron, the great city where the majority of the plot happens.
* PlaceBeyondTime: The original wielder of Barkaya'l remains in a realm of suspended time. He can't fight Astaroth himself, saying he would crumble to dust if he ever left.
* PlayerHeadquarters: They get changed a couple of times.
* PointOfNoReturn: Be sure to stock up before going on the path to confront the BigBad.
* PopulationControl: According to in-game documents, the Omikron government employs this to manage limited space and resources within the dome. Couples in Omikron are encouraged to have two children, then sterilized after the birth of the second. The punishment for having more than two children is never spelled out, but considering how oppressive the government is, it can't be pleasant.
* RedLightDistrict: Qalisar.
* RPGElements: The game includes fighting, FirstPersonShooter and {{Adventure}} segments, with skill at all these segments being determined by the stats of the body you are currently inhabiting.
* SacrificialLamb: [[spoiler:Poor poor Telis.]]
* SaveBothWorlds: Both Omikron and ''the real world''!
* SaveGameLimits: Saving your game uses up magic rings. If you run out of rings, you can't save again until you find more.
* SaveToken: The game had special rings you had to find. You could use them either to save or to get a suggestion.
* SdrawkcabName: [[spoiler:Namtar is just "Ratman" backwards, [[YouDirtyRat foreshadowing that he's not to be trusted]].]]
* SoulJar: The player's soul may inhabit the body of several characters. Also, [[spoiler:the sword Barkaya'l contains the souls of many powerful magicians.]]
* TakeUpMySword: How you obtain the CoolSword.
* TomeOfEldritchLore: The Book of Nout.
* UrbanSegregation: The city of Omikron is divided into four districts, each with its own style of architecture and fashion. People aren't allowed to move freely between them, but instead need special passes to do so.
* WhatHappenedToTheMouse: One of the powers necessary to get through the game is the Reincarnation spell, which basically lets you abandon your current body and take over a new one, without getting the old body killed. When you do this, the old body mysteriously vanishes. Where does it go? Did it die? Does anyone notice or care that you're possessing and then losing these people? Who knows?
* WideOpenSandbox: An early 3D example, you can explore the city of Omikron freely between (and often also during) missions: buy some stuff, read books, listen to music...
