Thumb & Pylon vs Iron Bastion

Your thumb is the power supply. Tap the core to make charge. Spend the charge on towers. Then keep tapping, because the towers drink it — and every tap that pays for a gun is a tap that is not scoring you points. That is the whole game: working out, wave after wave, what you can afford to stop doing. 34 LEVELS, FOUR ACTS Each one built around a single new idea, and each one asking you to survive it before moving on. The first teaches you to tap. The last assumes you remember everything since. NINE TOWERS, AND NONE OF THEM ARE UPGRADES OF EACH OTHER An Arc Node takes one target at a time. A Thermal Vent catches a whole pack at once. Some towers never fire at all — they sit among the others and make them faster, or cheaper to run. Where you put a tower matters more than how many you own. DAEMONS THAT PAY THEIR WAY Buy something that makes charge for you and your thumb gets a rest — or gets to score instead. Knowing when to stop tapping and start automating is half of it. BOSSES THAT DO NOT DIE POLITELY Ten hazards arrive on the backs of things built to break a line that was working. You will rebuild more than once. CLIMB THE BOARDS A leaderboard for every level, and one for your total across all of them. You see the top twenty and exactly where you stand — even if that is a long way down. PLAY ANYWHERE No connection needed. Underground, mid-flight, anywhere at all. Your scores catch up when you do. NO ADS. NO PURCHASES. NO SIGN-UP. Just the game.

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.
