Project Vesperi is a branching adventure game set in the year 2083, when Earth's depleted resources have forced humanity to search for signs of life in the Solar System. You play as Dr. Evelyn Roth, an astrobiologist with the UNE, stationed in Geyser Canyon on Venus, where abandoned terraforming experiments have created a habitable zone in one of the Solar System's most hostile environments. When a mysterious anomaly is discovered and an intruder emerges, you must make crucial decisions that will determine how far Evelyn will go to secure her discovery and protect humanity's potentially greatest discovery.
