About this game
From Student Demo to Indie Release
When we first shared the Project Vesperi Demo, the completed project was intended to be a free release similar in scope and quality to what we accomplished as students. Since graduating, we decided to expand and polish the project into becoming a more complete movie-length branching narrative game. As a result, Project Vesperi will launch at a small indie price, while the Student Demo will remain free as a snapshot of our original student work. We hope this better clarifies things, and we thank you for your understanding!
About the Game
FORGE YOUR OWN PATH
Dive into Project Vesperi to experience this movie-length sci-fi branching narrative. Play again and again to discover over ten different endings with variations based on the decisions you make throughout the story.
MAKE CHOICES THAT MATTER
You play as Doctor Evelyn Roth, a UNE astrobiologist dedicated to searching for potential signs of life across our solar system. When an anomaly is found on Venus, you will decide how far she’ll go to secure it when an intruder emerges.
FACE THE CONSEQUENCES OF YOUR ACTIONS
Your decisions as Evelyn will shape how characters in the station view you and act. Every choice, no matter how small, affects your ending and the characters you meet. Exploring the world will further impact your narrative gameplay experience, as you’ll find new pathways and choices to unlock during conversations. Depending on how you approach conflict, each character’s fate will be in your hands. Your choices matter, as every character can live or die.
DETERMINE THE FATE OF HUMANITY
The year is 2083. Earth’s natural resources have dwindled. The Unified Nations of Earth have launched missions across the solar system to search for signs of life on planets and moons. On Venus, abandoned terraforming experiments created a safe pocket of reduced pressure and heat. In this traversable zone, the UNE founded Geyser Canyon Station. This mission is known as Project Vesperi. On one of the least hospitable planets in our solar system, you must decide how humanity will react to what may be the greatest discovery ever made.
FROM STUDENTS TO INDIE DEVELOPERS
Featuring lifelike performances, rich world-building, and tense action sequences, Project Vesperi was developed within our student scope against all odds as a short impactful narrative game built from the ground up to be replayable. This game was made possible by a team full of college students and supportive collaborators who believed in our passion, and we couldn’t be more excited to finally be launching Project Vesperi on Steam.
Enter this turbulent near future and determine the fate of those on Venus and humanity in Project Vesperi. Thank you, and we hope you enjoy!
