Chaos;Head Noah, stylized as ChäoS;HEAd NoAH, is a visual novel that was developed by 5pb. and Nitroplus. The title was released in Japan by 5pb. on February 24, 2022. Some versions were censored to meet platform content requirements. It was localized into English by Spike Chunsoft and was released internationally for the Nintendo Switch and PC on October 7, 2022.


Japanese censorship[]

  • The Android, iOS, PlayStation 3, and PlayStation Portable versions were censored in order to receive a CERO rating of D (ages 17 and up) and be released on those platforms.
    • A Sequence in the "Crying Sky" Ending Route of Takumi experiencing all of the New Gen Murders was omitted due its gory and violent content.
  • Though the Nintendo Switch version received a CERO rating of Z (ages 18 and up), its content matches the other CERO D releases, instead of the PlayStation Vita and Xbox 360 versions, in which the CERO Z content appears to be the least censored. This is most likely due to the game being paired with its sequel, Chaos;Child, on the Switch Release, which also has a CERO Z rating.

International censorship[]

  • The listing for the PC version was removed from the Steam platform before its release date, reportedly due to its violent and sexual content,[1] but it was put back up again after public backlash.
  • All Japanese censorship applies

Where to find it uncensored[]

  • The PlayStation Vita and Xbox 360 versions in Japan are uncensored.
  • A Group of Fan Translators, The Committee of Zero, released a patch for the PC and Switch Versions that can be downloaded for free and restores all of the censored Content.
