About

Remember guarding a little brick base from waves of tanks, winning with one wall still standing, whispering "one more mission" long past bedtime? That war never ended. It grew up, and it has been waiting for you. I defended that base too. So I rebuilt the whole war the way my memories deserved: 140 missions, 19 bosses, battlefields that look like real places. And not a single ad in any of them. The first 8 missions are free: full missions, two boss fights, not a tutorial on rails. Play them like you own them. If it's not your game, delete it and we part as friends. If it is, one tap unlocks the entire war, forever. ONE WAR, FOUR FRONTS: 140 MISSIONS • Steel Crusade: the 80-mission flagship campaign, from first skirmish to final siege • Iron Labyrinth: 30 night missions under fog of war, where you hunt by the light of your own gun • Inferno: 30 missions through a burning hellscape of lava, web and bone • Endless Onslaught: waves that keep coming until you stop BATTLEFIELDS SOMEBODY ONCE LIVED ON Every map is a place, not a grid: rowboats tied up at the piers, wire lines sagging between poles, sandbags and tank traps at the walls, craters and shell casings with wildflowers growing back between them. Warm lamplight along the roads, and on every map one lamp that never lights. Dozens of small details on every battlefield, and the action stays razor-clear through all of it. NINETEEN BOSS FIGHTS The first run, the boss kills you. The second, you notice the pause before its salvo. The third, it's yours. None of them fall to reflexes alone: read the pattern, then break it. WHEN THE LINE IS BREAKING Airstrikes, escort drones, auto-turrets, and a base repair that rebuilds your wall with one tap while the shells are still falling. FOR THE RECORD Game Center leaderboards for your furthest stage, best run and highest Endless wave on every difficulty, built right in with no separate account. 34 medals: the first is called First Blood, the hardest asks for 10,000 kills. Someone reading this will earn it. YOURS. FOREVER. One purchase unlocks the entire war: every mission, every boss, every front, permanently. • No ads, no subscriptions, no accounts • Zero data collected. Check the privacy label • Fully offline: planes, basements, the end of the world The war never nags you for money. It only asks you to hold the line. I made Steel Sentinel alone, because the war I remembered deserved to grow up instead of just getting remade. If you ever guarded a brick base like it was your family, this one is for you. Deploy. Hold the line. Take the war to hell.

What's New in Steel Sentinel

1.1

August 10, 2026

This is Steel Sentinel's first update. If you already own the war, everything below is yours today, free. THE WAR GREW: 100 MISSIONS BECAME 140 Forty new battlefields, built by hand, join all three campaigns: forest ambushes, brick mazes, lake fortresses, chains of islands. Steel Crusade now runs 80 missions, Iron Labyrinth and Inferno run 30 each, the boss roster grew from 8 to 19, and the free missions now hold two full boss fights. GAME CENTER ARRIVES World leaderboards for your furthest stage, best run and highest Endless wave on every difficulty, plus 34 medals: the first is called First Blood, the hardest asks for 10,000 kills. The boards are brand new, so the top spots are still there for the taking. ENDLESS NOW FIGHTS IN WAVES Real wave assaults under a forged WAVE banner, a shield dome while you deploy, and progress that banks the moment a new wave begins. Losing a run no longer costs you the whole night. EVERY MAP CAME ALIVE Piers and rowboats, sagging wire lines, sandbags and tank traps, craters, bones, wildflowers. Warm lamps line the roads, and on every map one lamp never lights. That one is not a bug. Leave it be. Replay an old mission and see what grew where you fought. SHARPENED THROUGHOUT Shells travel faster and read cleaner in flight. Power-ups hold the field longer. The Inferno night floor runs colder so its fire burns hotter against it. And the whole war installs lighter than it did before. Hold the line.
