* PolishedPort: The [[Main/UpdatedRerelease Noah version]] for the Xbox 360 and [=PS3=] counts, with new routes and HD resolution. The Xbox 360 version in particular is uncensored unlike later releases of the Noah version, even the PC port of Noah.

* AdaptationDisplacement: More people know about the anime than the game it was based on.

* IdiotPlot: Most of the plot consists of Takumi trying to get away from everyone who could help him due to his paranoia.

* ParanoiaFuel: The fact that the main character is paranoid, everything is seen from his perspective [[spoiler:and he is not real (though one could easily argue that he is both real in some sense and not real in some sense).]]

* CompleteMonster: [[spoiler:[[CorruptCorporateExecutive Norose Genichi]], head of the NOZOMI Group,]] is a sneering, arrogant maniac who specializes in the MindRape of young girls. Operating as TheChessmaster to get the heroes, superpowered beings called Gigalomaniacs, to do what he wants to further his ends, [[spoiler:Norose]] orchestrates the gruesome New Gen Murders specifically to destroy the protagonist Takumi's sense of self and make him break down. He previously experimented on [[spoiler:Sena]]'s family, using her mother as a test subject in creating matter from artificial delusions. He forced a woman who had lost her baby to have a new one from her delusions until he decided he'd gotten enough information and ended the experiment, causing the woman to lose her mind and stab her eyes out, which Norose found quite amusing. He later has [[spoiler:Takumi's sister Nanami]] kidnapped to lure out Takumi. His ultimate goal is to [[spoiler:extract Takumi's DNA and use it to power [[MindControlDevice Noah II]], which he will use to control all humanity. Finally, he causes a destructive earthquake with the device before betraying and killing his two co-conspirators so he can rule by himself]]. While [[spoiler:Norose]] claims he has good intentions, he is [[NotSoWellIntentionedExtremist nothing more than a petty tyrant]] with a god complex seeking to enact his designs on [[StrawNihilist a world he sees as having no point]] by hurting those in his way.

* AdaptationDisplacement: While the Visual Novel isn't entirely obscure, odds are that if someone talks about ''Chaos;Head'', they're referring to the anime, not the Visual Novel.

* IdiotPlot: Most of the plot consists of Takumi trying to get away from everyone who could help him due to his paranoia.

* JerkassWoobie: Takumi isn't made out to be the most appealing protagonist; he's an antisocial, cowardly otaku who at first is really only concerned about maintaining his lifestyle. At the same time he's put through a fair amount of trials, accused of murder, and pretty much thrust into plot pretty forcefully. Not to mention [[spoiler: finding out he's a delusion]].

* ParanoiaFuel: The fact that the main character is paranoid, everything is seen from his perspective and [[spoiler: he is not real]]

* CompleteMonster: Norose is a sneering, arrogant, sadistic bastard with a [[AGodAmI god complex]] who specializes in MindRape, especially of young girls. What he did to Sena's family (and most especially the amusement he felt about it) was so far over the MoralEventHorizon that it begs belief and that was one of the ''first'' things that the audience knew about him!

* JerkassWoobie: Takumi isn't made out to be the most appealing protagonist; he's an antisocial, cowardly otaku who at first is really only considered about maintaining his lifestyle. At the same time he's put through a fair amount of trials, accused of murder, and pretty much thrust into plot pretty forcefully. Not to mention [[spoiler: finding out he's a delusion]].

* CompleteMonster: Norose.

* CompleteMonster -- Norose.
* IdiotPlot -- Most of the plot consists of Takumi trying to get away from everyone who could help him due to his paranoia.
* MoralEventHorizon -- Norose's treatment of Nana when [[spoiler:Rimi comes to rescue her]]. You can only really go downhill from there.
* ParanoiaFuel -- Where do I even begin?
** The fact that the main character is paranoid, everything is seen from his perspective and [[spoiler: he is not real]]

* CrowningMomentOfAwesome -- [[spoiler: At the end of the AA/A routes, Takumi gets killed by the BigBad and after a series of questions concerning his identity and status as a delusionary being, starts regenerating no matter how many times he's killed until he finally destroys Noah II]]
* HighOctaneNightmareFuel -- Plenty of it - this is a Nitroplus game, after all.
** A sample: all the New Gen murders in the game have mysterious elements, particularly the second, in which the dead man has [[spoiler:an eight-month old fetus sewn into his stomach; given the age of the fetus, it had to have been removed from the mother's body before birth.]] It is eventually shown, in flashback, exactly [[spoiler:who the mother is]] and how this happened. This troper REALLY wishes it hadn't been.
** Two more: [[spoiler: what happened to Sena's mother]] and during Takumi's last battle with Norose, he [[spoiler: is put under a delusion that he has been melted into a puddle ''with only his eyes remaining.'']] Eeep.
