One operator.
Five thousand tons of steel.
IRON NEST is a dieselpunk heavy-artillery simulator in which one operator controls a colossal war machine. Every lever, map mark, powder charge, shell, and firing decision is handled manually.
Receive intelligence through teleprinters and spotter reports, measure the tactical map, calculate firing solutions, load the guns, and correct each shot while enemy forces attempt to locate the turret.
