Build, automate, and defend a living steam-powered fortress. Design intricate pipe networks to route steam and water to turrets, factories, and massive mech steam warriors, where pressure and efficiency mean the difference between survival and collapse. Manage villagers to mine minerals, pump water, smelt ores, and craft custom turrets while relentless enemy waves test your engineering and tactical skill. Every system is interconnected — from boilers to battlements — turning your base into a roaring, mechanical war machine.
