The Science Adventure Series (SciADV, 科学アドベンチャー, 科学ADV, Kagaku Adobenchaa) is a series of visual novels planned by Chiyomaru Shikura and developed by 5pb. Games and MAGES., occasionally in collaboration with Nitroplus. The series, which began with Chaos;Head Noah in 2009, now spans seven main visual novel entries. The series also consists of other material, such as anime adaptations, light novels, and manga.
Spike Chunsoft currently holds the English-version publishing rights for the series outside of Japan. Previous rights holders included PQube Games and JAST USA.
Common elements[]

Each entry in the Science Adventure Series is part of a continuous, interconnected narrative. This means that the events of one title may be referenced in another, or even affect the other title’s events in their entirety. In the same way, a given character may appear in more than one of the entries, either physically or by other means.
At their cores, the titles of the series utilize science, conspiracy, and mystery as their main themes. A mysterious organization known as the Committee of 300 often influences the actions of the antagonists and malignant forces in the series, but the true extent of their influence is not fully known.
It is also worth mentioning that while some entries in the series are relatively light in terms of their imagery, Chaos;Head Noah and Chaos;Child sometimes feature heavy depictions of gore.

- Occultic;Nine: Originally released as a series of light novels written by Chiyomaru Shikura, it eventually received an anime adaptation and, later, a visual novel adaptation for the PlayStation 4, PlayStation Vita, and the Xbox One.

An expanded version of the visual novel, tentatively titled Occultic;Nine: New World, was tentatively planned to release in 2019 as DLC for pre-existing versions of the game and as a full release for the Nintendo Switch, before being delayed to an unknown date. According to Chiyomaru Shikura, this version of the game will expand the story and supposedly connect it to the Science Adventure Series.
- Anonymous;Code: Originally released on July 28, 2022 for the PlayStation 4 and Nintendo Switch. The story takes place in the distant future of 2037 and follows protagonist, Pollon Takaoka. He has the special ability to "save and load" at certain points in the story, which allows him to return to crucial past events. According to Chiyomaru Shikura, Anonymous;Code serves as the "culmination of the Science Adventure Series."
- Steins;???: An upcoming thematic sequel to Steins;Gate and Steins;Gate 0; It will have the same relationship to those visual novels that Chaos;Child has to Chaos;Head Noah. Its full title has not been announced yet.

Plot[]
- Chaos;Head Love Chu Chu! is the direct sequel to Chaos;Head Noah and a parody of visual novels in the romantic comedy genre. It is referred to as an "Exploding Delusions ADV," and continues the story where Chaos;Head NoAH left off.
- Steins;Gate: My Darling's Embrace is a Steins;Gate spinoff visual novel in the romantic comedy genre. It occurs in the Delta Attractor Field.
- Steins;Gate: Variant Space Octet (not to be confused with 8-bit ADV Steins;Gate), is a text adventure-styled visual novel.

- Steins;Gate: Linear Bounded Phenogram is a Steins;Gate spinoff visual novel comprised of several side stories. The visual novel takes a unique approach in that many of its stories feature characters other than Rintaro Okabe as protagonists.
- Steins;Gate 0 is a midquel to Steins;Gate, and is integral to understanding how the true ending of the original title was made possible. Rintaro Okabe returns as the protagonist of this title, but the game also features the first-person perspectives of other main characters.
- Chaos;Child Love Chu Chu!! is the direct sequel to Chaos;Child and a romantic comedy-themed visual novel. The game's plot, while largely focused on romantic and comedic interactions between the protagonist and his companions, also features more serious plot developments that take place after Chaos;Child's events.
- Robotics;Notes DaSH is the direct sequel to Robotics;Notes, and takes place half a year after the first title’s events.
- Steins;Gate 0 Elite will be a fully-animated remake of the visual novel using footage from the anime adaptation.
