The Iron Nest tutorial is Mission 1, "Calibration Fire," and it exists to teach the firing chain and the first-shot sequence before any real targets appear.

In Calibration Fire you learn to read an order, find the target on your map table from the given coordinates, lay the gun by hand, set the charge, and fire a deliberate calibration shot.

The mission completes with the "Just Calibrating" achievement, and it is the safest place to practice the breech, hydraulic, elevation, and bearing controls without time pressure.

The tutorial introduces the four controls you will touch every mission: turret bearing (traverse), barrel elevation, powder charge, and the shell selection from your supply truck.

Because shells do not randomly spread, the calibration shot in this mission proves the repeatability of the system — the same numbers always hit the same point.

After Calibration Fire, the How To Play page explains the full loop, and Mission 2 Fire and Light builds on it with the "Honour Salute" achievement.

Players stuck in the tutorial should slow down: Iron Nest rewards a careful, checked firing solution far more than fast clicking, and there is no penalty for taking your time.

This page separates documented information from assumptions so players can use it as a reference without treating unverified claims as fact. Check the in-game interface and official announcements when a mechanic, availability detail, or value may have changed after the source was collected.
