When the sovereign smelters of the North collapsed in Year 44, warfare ceased to be an enterprise of sweeping cavalry movements or delicate diplomacy. The conflict coalesced into an unyielding war of mechanical attrition along the jagged scars of the Great Basin. Heavy mechanized squads known colloquially as Boiler Brigades were assembled from reconditioned industrial tractors, mining pile-drivers, and salvaged iron bridge girders.
In Ironclad: Trenchbreaker, you enlist as a junior boiler-marshal assigned to the 14th Irregulars. Every sortie requires meticulous calculation of fuel ratios, replacement rivets, and high-tensile track pins. As your combat chassis suffers localized armor damage, internal fire hazards, and pneumatic line ruptures, survival hinges on your ability to perform field repairs under direct battery bombardment.
Between combat excursions, pilot squads retreat to mobile rail repair caravans. Here, players forge custom heat exchangers, weld scavenged railway track armor onto their hulls, and customize gear-ratio transmissions to match hostile terrain—from mud-drowned riverbeds to jagged slag deposits.
