IRON NEST Shell Guide

Choose ammunition by target effect, then confirm charge and firing data before loading.

Evidence map reviewed: Aug 9, 2026

Evidence boundary

Shell labels documented in older guides are treated as version-sensitive; the no-unload rule is confirmed separately by a developer.

Choose by intended effect

The shell is part of the mission solution, not just the final loading choice. The official FAQ describes destructive, utility and battlefield-control ammunition inspired by First World War and interwar heavy artillery.

Common shell roles

  • AP: armor-piercing ammunition for hardened or underground targets. The community basics guide also treats it as a precise option when friendly units are too close for a wide blast.
  • HE: standard high explosive for a single surface target or a tight group.
  • HCHE: a higher-capacity explosive option with a wider effect area in the community guide.
  • SMK: smoke used to screen or force friendly movement when the mission calls for it.
  • STAR: illumination ammunition that reveals an area around its impact and supports night or information-gathering tasks.

The official FAQ additionally names fragmentation, chemical rounds such as phosgene and tear gas, propaganda-leaflet shells and unrevealed experimental ammunition. Availability can depend on progression, mission and version, so this page does not present every mentioned type as immediately unlocked.

Loading checklist

  1. Confirm the target type and objective.
  2. Select the shell using the current in-game label.
  3. Measure the range and choose a powder-charge amount the calculator accepts.
  4. Generate the elevation card before committing the load.
  5. Recheck shell and charge at the final checklist before firing.

Loading is a commitment

A developer answer confirms that a loaded gun cannot simply be unloaded. If the powder amount is wrong, recalculate elevation for the actual charge. Other recovery options are using the second gun, changing to a suitable target, or firing safely before reloading. This is why target, shell and charge should be settled before the loading bridge and ramming sequence begins.

Version-sensitive labels

The AP, HE, HCHE, SMK and STAR abbreviations come from a community guide that spans pre-release and release-era updates. The broad roles are useful, but the live requisition console remains authoritative for the names, unlock state and mission availability in your build.
