Steelpolis is more than just a train - it's the last hope of a crumbling empire, and you're in charge. I've been waiting for Steel Artery ever since it first popped onto my radar back in 2025, and it's finally pulled into the station. The self-branded 'train city builder' bears closest resemblance to the likes of colony sims in the vein of Rimworld and Oxygen Not Included. The big difference is that you're on a moving train. Boasting gorgeous pixel artwork and the need to exert careful influence on an autonomous, self-satisfying population, it's a rich simulation that will look different with every playthrough.
