Story
You are at the frontier of human-charted space in a small mining ship, tasked with expanding humanity's footprint amongst the stars. To succeed, you’ll need to collect resources, automate production, expand your base of operations, and research new technologies. You start out with a single mining ship in a resource-rich asteroid belt. Use your scanners to find the best places to mine, and then refine the resources on your ship. Build a space station to set up a permanent base of operations which you can begin to expand and automate. Onboard your stations, the factories you build are the heart of your industrial operation . Build machines, connect them with conveyor belts, and plan your production lines to keep everything flowing at full efficiency. Once that's running, that same logic extends across systems - automated supply routes between stations , and a fleet that keeps everything provisioned while you focus on expanding your operations. Every ship and station is yours to design, inside and out . Module by module, you decide cargo capacity, reactor placement and weapons - whatever the situation calls for. Save designs to use again, share them with friends, or build...
