Games] and MAGES., occasionally in collaboration with Nitroplus. The series, which began with Chaos;Head NoAH in 2009, spans seven main visual novel entries and several side visual novel entries.

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 single 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. In some cases (particularly in the Chaos; titles), thriller is also a primary theme. It is also worth mentioning that while some entries in the series are relatively light in terms of their imagery, Chaos;Head and Chaos;Child sometimes feature heavy depictions of gore.
