IRON NEST Heavy Turret Simulator
Your complete guide to IRON NEST: Heavy Turret Simulator — the dieselpunk artillery sim where you command a colossal turret in an alternate-history Spain on the brink of civil war. We chart every shell, system, region and firing solution.

From a two-person team, IRON NEST: Heavy Turret Simulator is a first-person dieselpunk artillery sim. You don't run the battlefield — you dominate it from inside one enormous war machine, reading intel, solving ballistics and pulling the trigger on thousands of tons of steel.

Orders come from High Command, but the choice is yours. Newspaper reports turn your fire into a grim story.
