IRON NEST: Heavy Turret Simulator has 33 official Steam achievements: 14 campaign-completion achievements, 15 achievements for earning gold on every medal in a named operation, and four spoiler-sensitive city outcomes. This checklist gives each mission one canonical tracking row without pretending the short Steam descriptions reveal hidden medal thresholds.
2950790 Steam achievements list. Community layer: A current gold guide reports categories and thresholds, but exact requirements remain community-reported until reproduced on the current public build. PATCH 1.0 (1577) is the testing baseline for replay state.Mission checklist
The missing White Shells completion achievement is not a gap to fill with a fictional name. The official Pride of Castile condition is enough to verify that White Shells has an all-gold achievement.
Four city outcomes — spoiler warning
The official list also contains four outcome achievements:
- A City Silent — official text establishes a city wiped from the map.
- A City in Celebration — official text establishes a city that comes out to meet you.
- A City Subdued — official text establishes a city that kneels and calls it peace.
- The Road Not Taken — official text establishes a city spared and a different road.
Those descriptions prove distinct outcomes, not the exact trigger chain. Hospital, civilian, friendly-fire, shell-class, and mission-choice explanations remain in the spoiler-marked Endings guide and require controlled saves. Do not infer causation merely because two events occurred in the same run.
Medal categories seen in current reports
Current community gold guidance uses categories such as allies killed, average accuracy, kill streak, counter-battery time, enemies killed, kills per shot, no recon, requisition spending, first-shot result, and triple kill. These labels are useful when transcribing a result screen. They do not prove that every category appears in every operation or that a reported threshold is current.
How to use this checklist
Finish each operation once for understanding. Check its completion achievement after the newspaper and save transition. Photograph every in-game medal row, then choose one missing category for the next replay. Keep shell, route, and other variables stable while changing the suspected requirement.
After confirming individual medals, combine the verified sufficient behaviors in a clean run. Capture the internal all-gold result and the Steam achievement separately. The platform notification confirms the achievement; it does not expose the hidden arithmetic.
Use a simple local record: operation, patch, mode, attempt, shots, requisitions, recon/abilities, allies affected, targets/effects, elapsed boundaries, medal rows, newspaper, and Steam result. Do not upload a raw save or edit achievements to fill the list.
Patch and save safeguards
PATCH 1.0 (1547) fixed an incorrect or duplicate High Tide newspaper and record. PATCH 1.0 (1558) fixed save corruption and inability to enter missions after a crash. PATCH 1.0 (1577) fixed mission events not resetting on replay plus turret position/movement state between missions.
Research on older behavior can misidentify a threshold when the real cause was stale mission state. Update, start from a normal menu transition, dismiss the result newspaper, and let Steam Cloud synchronize. Follow Saves and Cloud before any ending or gold experiment that risks progression.
What remains unverified
The exact medal names and numeric thresholds for all fifteen operations, whether all four medals always register simultaneously, the exact no-recon distinction, timer start/end points, requisition accounting, hidden collateral rules, and the full city-outcome trigger graph still require hands-on current-build testing. Community values are leads, not official constants.
