Iron Bastion

The battlefield never stops. Your bastion fires automatically—but survival depends on the choices you make. Iron Bastion is a modern military tower-defense roguelite built for fast, focused runs. Destroy advancing combat units, spend battlefield credits on tactical upgrades, and select powerful new capabilities as each operation escalates. CHOOSE YOUR THREAT Start as a Beginner, test your command experience, or face the brutal Pro deployment. Each difficulty changes enemy pressure, rewards, and the pace of battle. BUILD A DEADLIER BASTION Improve caliber, reload speed, armor, critical systems, and more during every run. Combine upgrades into a build that can withstand the next wave. ADAPT BETWEEN WAVES Choose one of three roguelite upgrades and reshape your strategy. Every decision changes how your defense platform performs under pressure. SURVIVE AN ESCALATING WAR Enemy strength adapts as the battle continues. Elite threats and increasingly punishing waves prevent a successful defense from becoming comfortable.
