Projekt: Passion is an adult visual novel set in an original futuristic world where humanity has spread across the galaxy after abandoning Earth. The story begins with a personal crisis: the protagonist survives an assassination attempt, loses their apartment, and discovers that their partner has vanished. Finding her becomes the starting point for a mystery that may grow into a much larger adventure.
Its play is centered on story and characterization, with dialogue choices that let players shape the protagonist’s personality. Romance is optional: players can pursue one character, several, or none, with potential partners including humans, aliens, and androids. Comedy and drama share space with animated, voice-acted cutscenes, while lore entries offer additional context for those interested in the setting. The game also lists achievements with bonus scenes and images, and animated scenes are among its documented presentation features.
As a single-player visual novel, Projekt: Passion is designed for an individual, story-led experience rather than a shared multiplayer session.
