The city of Newton in 2087 runs on Trance, a neural network people plug into rather than face the world outside. An AI called ZOEA monitors everything. Three characters move through this: a Trance-addicted woman who rarely leaves her apartment, a government security agent, and a geneticist whose past is catching up with him. Technobabylon is a point-and-click cyberpunk game with the bones of a police procedural, built on the Gemini Rue engine and equally interested in the ethics of surveillance as in its conspiracy plot.
