IRON NEST Heavy Turret Simulator is an artillery simulator in the style of dieselpunk, in which you have to control a huge 5,000-gun battle tower in the alternative history of Spain in the 1920s, which is on the brink of civil war. You manually control every aspect of this colossal machine adjust the scales, rotate the guidance wheels, calculate ballistics, and choose from 30 types of ammunition, including armor piercing shells, smoke screens, and gas shells. The game combines tactical decision making with practical control of mechanics: you intercept radio communications, study aerial reconnaissance photographs and perform fire missions based on orders from the supreme command or requests from the front line.
