Univoyager
SteamAbout Univoyager
The Universe is Yours—Without Limits.
Set in the fourth millennium, you enter a post-apocalyptic era where humanity has abandoned the ruins of the past to forge a new civilization among the stars. From your cockpit, you are free to explore, trade, and combat in a universe rendered at a true 1:1 scale, where every point of light in the sky is a destination you can actually reach.
Core Features
•
Seamless Universe: No loading screens, no "warp" tricks. Transition from landing on a planet’s surface to orbiting a distant star in one continuous journey.
•
True-to-Life Scale: Planets, stars, and the vast voids between them are represented in real-world proportions.
•
Hard Science Physics: Experience a flight model governed by gravity, atmospheric drag, and orbital mechanics.
•
Authentic Star Map: Explore a database of over 100,000 real stars and Solar System bodies calculated using actual or consistent orbital data.
•
Infinite Detail: High-resolution terrain is generated by blending real-world data with advanced procedural algorithms for infinite detail.
•
Different Play Modes: Engage in challenging Missions, follow a narrative-driven Campaign or forge your own path in the enhanced Freefly Sandbox mode.
•
Full Pilot Control: Native HOTAS support with fully customizable digital and analog mapping.
•
Moddable: Game is designed to be moddable, from the assets to the missions.
A Seamless, Real-Scale Reality
In Univoyager, "Real Scale" is the foundation of the game. When you see a moon in the sky, you can fly to it. There are no instances and no interruptions. Take off from a spaceport on Earth and land at an outpost in Alpha Centauri without a single loading screen.
Custom Technology
Univoyager is the culmination of over 15 years of independent development and it is powered by a proprietary, custom-built 3D engine engineered to handle the staggering distances of space allowing for a seamless exploration of space on a truly massive scale.
Realistic Physics - Refined for Fun
Master the art of flight. The engine simulates gravity, collisions, and atmospheric drag, allowing for authentic orbital maneuvers and high-stakes re-entries. While realism is a priority, acceleration and extreme speeds have been tuned to ensure the universe remains traversable and engaging within "human time."
Flight Modes: From Rookie to Ace
Spaceflight is challenging, but Univoyager adapts to any skill level:
•
Automatic Navigation: The ship’s computer manages thrusters to correct trajectories and fight inertia, ideal for flight without atmosphere.
•
Manual Mode: Designed for expert pilots who demand total control. Manage individual thrusters to perform complex Newtonian maneuvers in the vacuum of space.
Freefly Sandbox
The Freefly Sandbox is a single player ecosystem where you define your existence. In this mode, the galaxy is populated by computer-controlled entities and dynamic systems:
•
Dynamic Combat & Interaction: Encounter and engage with computer-piloted adversaries.
•
Communication: Contact and interact with Air Traffic Control towers and other adversaries
•
Economy & Missions: Accept diverse missions, engage in a various trading system, or hunt for commodities.
•
Choose Your Path: Live the life of a law-abiding citizen or embrace the shadows. From merchant and mercenary to the life of a feared pirate.
Procedural Worlds
By combining real data with procedural generation, Univoyager features a portion of the galaxy that is both scientifically grounded and infinitely detailed. Explore millions of worlds with different mountain ranges and terrain, all while keeping the game’s disk footprint minimal. Visit procedurally generated outposts, sprawling cities on Earth, and lonely stations on the edge of the galaxy.
Hardware & Immersion
Univoyager includes full support for HOTAS (Hands On Throttle-And-Stick) setups with deep customization.
Note: Head-tracking and VR support are currently in development and will be included in future updates.
