IRON NEST Gold Medals: 15 Achievements & Known Conditions

Use this local checklist to track all 15 IRON NEST Gold Medal achievements and the known condition categories for each mission. Official achievement mappings, community-reported threshold data, and unknown or conflicted conditions remain separate instead of being presented as one equally certain list.

Looking for IRON NEST gold medal requirements? The checklist covers all 15 official mission achievements and shows known community-extracted conditions where evidence exists. It does not claim a complete current-build threshold set; unknown or conflicted requirements stay labelled instead of being filled with guesses.

Evidence status: The fifteen mission-to-achievement mappings are official-confirmed. Most threshold values are community extraction reviewed from 1.0 (1558), not a current-build verification. Triple Kill, hidden no-recon requirements, White Shells, and several comparison rules remain conflicted or unknown.

Gold Medal achievements and known conditions by mission

Use the mission index below to find each official all-Gold achievement, the known condition categories, and the evidence status. Select No known conflict for rows without a recorded conflict, or Conflicted / unknown for rows that still need a fresh result-screen check. Neither filter means the values were reverified on 1.0 (1622) or the community-reported build 1663.

Gold achievement not unlocking? Check these first

1. Same run versus separate replays: the cited Steam community guide reports that the all-four-Gold-in-one-run achievement bug was fixed in build 1663 and that separate attempts can count. This is a community report, not first-party patch confirmation; if your installed build is older or unclear, capture the result screen before repeating a mission.
2. Comparison direction: confirm whether the requirement means at most, at least, under, or over. A copied comparator can reverse the target.
3. Hidden no-recon condition: some no_recon_with_kills rows may combine no purchased reconnaissance with an undisclosed kill floor. Do not assume that avoiding recon alone is enough.
4. Build mismatch: most candidate thresholds were reviewed from 1.0 (1558). The site's last independently reviewed gameplay baseline is 1.0 (1622), while the cited community guide reports achievement fixes in build 1663. Neither later build label is a blanket verification of the extracted thresholds, so recheck any row that disagrees with the live medal panel.
5. Known conflicts: Triple Kill, High Tide's duplicated field, and White Shells remain unresolved or incomplete. Use the live objective and result screen rather than forcing a disputed value.

The checklist stores completion only in your browser. It does not connect to Steam, upload progress, or claim that a checked mission met hidden game conditions.

Scoring dimensions in the extracted data

Across the extracted data, medals evaluate combinations of:

• shots fired;
• friendly casualties;
• enemies killed;
• consecutive kill shots;
• kills per shot;
• requisition spent;
• reconnaissance use or kills without reconnaissance;
• time to first shot;
• Counter-Battery time remaining;
• Triple Kill timing;
• an internal accuracy or error measurement.

A displayed internal value such as 0.3 should not be rewritten as a percentage until the game UI meaning is confirmed.

Stable examples and disputed thresholds

Calibration Fire is consistently reported as requiring no more than one shot for its extracted Gold threshold. Fire and Light is consistently reported as no more than four shots. Many friendly-casualty goals require zero, but each mission should still be checked individually.

Counter-Battery has stronger support for nine enemy kills than the ten copied by several newer pages. Its Triple Kill time remains conflicted. High Tide data appears to duplicate a consecutive-kills field. White Shells has no reliable complete threshold set.

Some no_recon_with_kills records may require both no purchased reconnaissance and an undisclosed kill count. Secondary pages that insert a fixed number can create impossible or misleading conditions, so this checklist labels those rows rather than filling gaps.

How to verify a mission cleanly

1. Record the game build and selected mode.
2. Capture the medal panel before the run if it displays goals.
3. Complete all candidate Gold conditions in one attempt where practical.
4. Capture the result screen and the Steam achievement state.
5. Record exact comparison direction: at most, at least, under, or over.
6. Re-run one boundary value when a threshold is uncertain.
7. Keep the older build result when a patch changes the requirement.

For mission order and achievement names, see all missions. Use the Mission 3 Liberation walkthrough for the previous operation and the Mission 4 Counter-Battery walkthrough for the two-phase route, timer preparation, and version-sensitive Scout/STAR notes. The broader Counter-Battery mechanics guide retains the Demo history and evidence conflicts.

For current mode availability rather than medal conditions, see the multiplayer and co-op status.

Sources and data quality

• Steam global achievements — official all-gold achievement names and mission descriptions.
• Steam gold medal data guide — primary evolving community data source, with developer participation in comments.
• Ninewiki gold requirements, Treyex gold requirements, and Guidexon requirements — secondary comparison sources; agreement may reflect shared lineage rather than independent testing.

Content review updated August 26, 2026. The threshold data remains tied to the previously reviewed 1.0 (1558) build unless a row is explicitly reverified. The site's last independently reviewed gameplay baseline is 1.0 (1622), while the community guide reports selected achievement behavior from build 1663; that report is not first-party confirmation of the live Steam build or a full threshold recheck. Achievement names are official; thresholds remain community-derived with the listed conflicts.
