Survive the Depths of the Outer Sol System

Sol Survivor is a highly immersive multiplayer space-survival sandbox that challenges you to establish a permanent foothold in the freezing, distant reaches of our solar system. Whether you are venturing out as a solo explorer, hosting a private world for your friends, or joining an existing crew via Steam lobbies, your primary mission is transformation. Begin your journey with a fragile, bare-bones EVA (Extravehicular Activity) work site and gradually engineer it into a massive, fully functional orbital habitat.

Master Modular Space Station Construction

Experience deep engineering gameplay as you construct your station piece by piece. Sol Survivor emphasizes modular building mechanics, allowing you to design complex structures using habitat panels, octagonal tubes, pressurized endcaps, and high-tech utility systems. You are not just placing pre-made assets; you are designing a living, breathing station. From intricate wiring and pipe routing to installing power grids, lighting arrays, and interactive control screens, every system you build is designed to be physically persistent, allowing your base to grow and evolve over time.

Advanced Zero-G EVA and Movement

Navigation in Sol Survivor is built on realistic Newtonian physics. Master the challenges of zero-gravity movement as you maneuver through the vacuum of space. With sophisticated suit controls, thruster damping, and construct-anchoring mechanics, you must learn to navigate your surroundings with precision. Our physics-based system ensures that players and objects remain physically anchored to your station, creating a grounded and tactile survival experience that rewards skill and spatial awareness.

Persistent Multiplayer Worlds

Unlike transient match-based games, Sol Survivor is built for longevity. Our world-hosting system allows you to create persistent saved worlds that remain exactly as you left them. Whether you are collaborating on a mega-structure or maintaining life-support systems, your progress is saved and ready for whenever your crew logs back in. With integrated Steam lobby support, managing your squad, joining friends, or setting up secure private servers is seamless and intuitive.
