This Iron Nest walkthrough covers the full 15-mission campaign in order, from the Calibration Fire tutorial through to the branching finale White Shells.

Mission 1 Calibration Fire teaches the firing chain and the first-shot sequence and grants the "Just Calibrating" achievement on completion.

Mission 2 Fire and Light grants "Honour Salute" (gold "Marksman's Honour"), Mission 3 Liberation targets five infantry positions and an armored ammo depot ("For Their Own Good").

Mission 4 Counter-Battery is the timed reply mission ("First Reply"), Mission 5 Iron Road is "All Clear" (gold "Crowned in Brass"), Mission 6 Siege of Cartagena is "Breakout" (gold "Naval Commendation").

Mission 7 The Gorge is "Cold Start" (gold "Valour Under Fire"), Mission 8 Rock of Gibraltar is "Flying False Colours" (gold "Order of Merit"), Mission 9 Dead Reckoning is "Steady Hands" (gold "Quiet Precision").

Mission 10 Fire on Call is "The Gun Answers" (gold "Iron Discipline"), Mission 11 High Tide is "Beachhead Denied" (gold "Coastal Defence Medal"), Mission 12 Blind Fire is "Nothing Was There" (gold "Unshaken").

Mission 13 Phantom Battery is "Mirror Image" (gold "Master Gunner"), Mission 14 Final Harvest is the night mission "In the Dark" (gold "Night's Precision"), Mission 15 White Shells ends the campaign.

White Shells is the only mission that branches: the shell you choose over the final city triggers one of four ending achievements and the gold "Pride of Castile" medal.

Each mission reuses the same deliberate firing loop, so the walkthrough focuses on target-finding, bearing, and which shell solves the objective rather than on combat reflexes.
