Explore Mission ModesThe Firing Loop at a Glance
IRON NEST turns one firing task into a chain of operator decisions. The developer FAQ describes the broad sequence:
Receive the order through the teleprinter.
Identify the information needed for the shot.
Measure the target on the tactical map.
Enter the measured values in the in-game fire-control interface.
Choose ammunition and prepare the loading sequence shown in the game.
Set the gun's elevation and horizontal direction.
Fire, then review the mission result and any new information.
This field manual explains where each system fits. It does not replace the current in-game interface or promise a particular shot or mission result.
