The Science Adventure Series, or SciADV Series for short, is a collection of stories originally in the forms of Visual Novels. They all span among other different forms of media (such as anime, manga, light novels, drama CDs, and stage plays), whilst sharing a single universe. Each main entry has its own relatively self-contained story, but they are all united by some common themes and threads, and some characters return in later entries.
The world of SciADV is a world much like our own, with bustling cities and people going about their daily lives. However, unbeknownst to the general populace, the sinister group known as the Committee of 300 lurks in the shadows, controlling various powerful organizations and leading them in their mission to establish dominion over the world and reduce its human population to a manageable billion. Their goal: to create a utopia without wars or conflict, a world where the human mind is enslaved to their collective will. The various stories follow different groups of ordinary people who nevertheless get themselves entangled into the Evil Plan of a Committee-controlled organization, and find themselves with the daunting task of fighting a conspiracy that towers over them and everyone they know.
The series is part of the collaboration between Japanese visual novel developer nitro+ and video game manufacturer 5pb. Currently, the Science Adventure series covers six visual novels that are the mainline entries, though there are oodles of side material (manga, audio dramas, etc.) and fan discs that act as companion pieces to the mainline entries. The series is planned by Chiyomaru Shikura, the CEO of 5pb., music composed by Takeshi Abo and Zizz Studio, written by Naotaka Hayashi along with other writers, and features character designs by artists including Mutsumi Sasaki and Huke.
Another series of visual novels (and other media) by the same creators exist under the 'Science Visual Novels Series' (or SVN) name and is made up of Occultic;Nine and Anonymous;Code. They exist in a different shared universe than the SciADV Series (though the SciADV games do however exist as their fictional game versions in this universe). Or so we were originally told until Shikura held a livestream in 2017 stating that "SVN" isn't a separate series, but rather it's the Western nickname he made up for SciADV, alongside the fact that the O;N visual novel removed all the S;G references in its script.

Tropes common to all instalments in the SciADV Series:
- The Anime of the Game: Each game has received or is receiving an anime adaptation.
- Big Bad: The Committee of 300 are the overall villains of the series, as they plan to reduce humanity to a population of one billion and unite the remainder under a single totalitarian utopia where peace is maintained through the eradication of free will. Every individual Big Bad has some kind of connection to them, direct or otherwise.
- Dystopia: What the Committee of 300 intend to create in the future and what the main characters of each game are trying to stop, whether they know it or not.
- Idiosyncratic Episode Naming: Every installment uses a semicolon between two words.
- The Illuminati: The Committee of 300 serve this role, as they control organizations across the world, and aim to create a One World Order.
- The Man Behind the Man: "The Committee of 300" has been pulling the strings behind all the antagonists in each game.
- Greater-Scope Villain: The always offscreen Committee of 300, who plan to reduce humanity to a population of one billion and unite the remainder under a single totalitarian government. Although they are directly responsible for Project Noah, Project Mars, Project Atom and SERN's Z-Program, they only act by proxy and are never shown or identified.
- Science Fiction: As the title suggests, the primary genre for each game, using real scientific concepts and theories, but also crossing over into fictional territory, using non-accurate science.
- Shared Universe: Constant references, Continuity Nods and characters appear between each installment, some more obvious than others.
- Thematic Series: The stories all take place in the same world, and all of them deal with a group of characters taking down a conspiracy, but minus 2 of the entries, each entry rarely reference the stories outside of their specific duology (for example, you'll rarely see Steins;Gate making references to the Chaos; entries), the main unifying factor is the Overarching Villain, the Committee of 300.
