Workers are your arms and legs on the cold surface of Mars. They are unmanned rovers that shuttle resources around your base and also handle the construction and eventual scrapping of buildings. Even though they move autonomously, they are an extension of your own self.
You begin with a single worker -- it's equipped with construction drones that can 3D print entire buildings. Each worker requires a hub to operate from: they’ll use the hub to store materials and service the surrounding area. The Landing Site and Worker Hub both serve as centers for workers.
Early concept sketches of the trusty worker!
When we started working on the game, we knew we wanted our workers to replicate the kind of experience The Settlers had. While the little serfs in that game live on the roads, we’ve decided for our workers to live in buildings so they can be protected from inclement Mars weather. After experimenting quite a lot, we found it felt best to add a special building specifically for workers! That’s how we designed the Worker Hub.
Workers are built automatically in Worker Factories as long as there are vacant hubs. You'll need to build many replacements since workers have such a tough life: the harsh Martian climate and solar radiation eventually causes irreparable decay. That’s why it’s important to have factories that constantly create fresh, new workers. In a way, we were loosely inspired by Von Neumann probes -- self-sufficient constructs that can build self-replicating bases or even copies of themselves. While you start Mars with only a single yet capable worker, by the end of the game you’ll command a legion of them!
