Chaos Head

Based on a Japanese visual novel developed by 5bp and Nitro+, Chaos;Head is a delusional murder mystery story, with strong elements of gore, psychology and science fiction. The game uses a feature called a "delusional trigger", which allows the player adjust the ‘realness’ or ‘surrealism’ of the perspective of the main character, which directly affects the storyline.

The main character, Takumi is a troubled young man who struggles to distinguish reality from his delusions, while being pursued by the perpetrator of a series of bloody murders, (or so he thinks). His travels take him in and around Shibuya, Tokyo and his adventures bring him in contact with various scientific themes such as the concepts of matter, antimatter, and the Dirac sea.

Development

Chaos;Head is a collaborative production between 5pb. and Nitroplus with additional assistance from Red Flagship. The original concept art and scenario came from two 5pb. staff members, Yukihiro Matsuo and Naotaka Hayashi respectively. The character designer was Mutsumi Sasaki and Choco handled the product's design. 5zizz studio contributed the music to the game and Nitroplus handled the development and production of the game. Chaos;Head was temporarily named as Gigalomaniacs (ギガロマニアックス) when it was first announced.
