Starbase Simulator is a solo-focused sandbox project built in Unreal Engine 5, created by indie developer Ashtorak. It lets players design, test, and pilot their own modular spacecraft in a physics-based environment. Centered on orbital mechanics and realistic movement, the simulator focuses on experimentation rather than combat, narrative, or multiplayer, making it ideal for hobbyists who enjoy building and problem-solving in space.

Build and test modular spacecraft

At its core, Starbase Simulator is about assembling functional starships from modular components. Players can configure engines, thrusters, and structures to see how their designs behave under realistic physics. The emphasis is on trial and error—acting as a virtual prototyping lab for creative ship concepts. Without missions or PvE encounters, the experience leans toward exploration of mechanics rather than delivering traditional game progression.

Learning curve and community support

The simulator keeps its interface minimal, which makes it approachable for testing ideas but challenging for new players with no background in modular design or orbital systems. Despite its simplicity, it performs well even on modest setups. An active Discord community helps fill the gaps, offering shared designs, troubleshooting tips, and feedback directly to the developer. Ongoing updates reflect the creator’s responsiveness to suggestions, keeping the sandbox fresh.

Final thoughts

Starbase Simulator is not a conventional game—it’s more of a creative tool for spacecraft enthusiasts and physics tinkerers. Without objectives, combat, or multiplayer, it caters to a niche audience interested in experimentation over action. For those who love testing designs and exploring orbital mechanics, it offers a rewarding sandbox in the stars.
