Purified Steel

Unstable buildings were once massive air purifiers, collecting the dangerous fabric fumes and turning them into fresh oxygen for ironclad city,thanks to train wagons arriving from multiple train tracks full of green prototypes working all day for this continuous cycle.

During the great Iron and Fire war, all these buildings were bombed by junkers JU87-Stukas piloted by the tremendous armed schemers, to weaken enemy units, making them unstable and often even dangerous explosion zones.
