About Project Vesperi
Project Vesperi is a branching sci-fi narrative set in 2083. You play as Doctor Evelyn Roth, a UNE astrobiologist searching the solar system for signs of life. When an anomaly is found on Venus and an intruder emerges, you decide how far Evelyn will go to secure it.
The mission on Venus
Earth’s natural resources have dwindled, and the Unified Nations of Earth has launched missions across the solar system to search for life on planets and moons. Abandoned terraforming experiments on Venus created a traversable pocket with reduced pressure and heat, where the UNE founded Geyser Canyon Station. The mission is known as Project Vesperi, and its discovery may shape how humanity responds to what could be its greatest find.
Choices and consequences
Your decisions affect how the station’s characters view and treat Evelyn, which characters she meets, and how the story ends. Exploring the world can reveal new paths and unlock conversation choices. How you approach conflict determines each character’s fate, and every character can live or die.
The story has over ten different endings, with variations shaped by your decisions. It is designed to be replayed, with choices throughout the narrative affecting the outcome.
