Science Adventure[a] is a series of science fiction visual novel video games developed by 5pb., Nitroplus, and Chiyomaru Studio. The first entry in the series, Chaos; Head, was released in 2008, and is followed by Steins; Gate, Robotics; Notes, Chaos; Child, Steins; Gate 0, and Robotics; Notes DaSH, and the upcoming Steins;???. The series also includes the two Science Visual Novel[b] games Occultic; Nine and Anonymous; Code, six spin-off games based on Chaos; Head, Steins; Gate, and Chaos; Child, and other media including anime, manga, light novels, audio dramas, and stage plays.
The main games and their spin-offs all take place in the same fictional universe. Chaos; Head and Chaos; Child focus on individuals with reality-altering powers, while the Steins; Gate games focus on time travel. The player can affect the course of the story by making certain choices: in Chaos; Head and Chaos; Child this is done by choosing what kind of delusions the player characters experience. The choices in the Steins; Gate games and Robotics; Notes are made via messages set by the player via an in-game cell phone and tablet computer, respectively.
The series is planned by Chiyomaru Shikura, the CEO of 5pb., composed by Takeshi Abo and Zizz Studio, written by Naotaka Hayashi along with other writers, and features character designs by artists including Mutsumi Sasaki, Huke, and Tomonori Fukuda. The developers aimed to make the series set within reality, as Shikura felt it made it more relatable and believable. The series has been commercially and critically successful both in Japan and internationally, selling more than expected for the genre and helping to establish 5pb. as a game developer.
