Science Adventure Series

The Science Adventure (科学ＡＤＶ, Kagaku Adobenchaa) series is a collection of stories that span among different forms of media, sharing a single universe. The series is part of the collaboration between Japanese visual novel developer nitroplus and video game manufacturer 5pb. Currently, the Science Adventure series covers five visual novels, and various other media.

Plot
Each of the stories comprising the Science Adventure series covers an individual set of characters in a different setting (Chaos;Head and Steins;Gate both occur in Tokyo, but in different times), tackling a different metaphysical concept for each story (the power of the mind for Chaos;Head, time travel for Steins;Gate, and robotics and augmented reality for Robotics;Notes). However, these stories occur on the same world and have a connection with each other. Currently, a mysterious organization called the Committee of 300 has been mentioned to have a great influence to the antagonists of each story, and the relevance of this organization to the greater story to be told by the series is yet to be revealed.

Anime adaptations and chronological order:
This order isn't recommended upon your first viewing. As with the Monogatari series, the recommended viewing order for first time viewers is release order. Extra Note: The anime isn't recommended. Read the visual novel instead. If you truly wish to consume that part of the Science Adventure story in anime form, watch Chaos;Child Episode 0 instead. Note: Episode 23 will repeat some of Steins;Gate 0's Episode 23. The canonicity is also widely debated, and may be disputed by Holy Day of Scourge. This is widely regarded as non-canon and entirely skippable. As with Chaos;Head, this anime isn't recommended either. That said, after reading the visual novel, watching episode 10, 12 and the Silent Sky OVAs is recommended though.
