Divide By Zero DOS Games: Orion Conspiracy & Guilty.

Divide By Zero was a British studio celebrated for witty, story-heavy point-and-click adventures on DOS. Working with publishers like Psygnosis and Domark, the team delivered a string of cult favourites: Innocent Until Caught, its two-protagonist sequel Guilty, the darker sci-fi mystery The Orion Conspiracy, and the whimsical caper The Gene Machine. Built on the studio’s own Interspective engine, these games mix sharp dialogue with puzzle-driven exploration and cinematic art to create memorable worlds.
