The exact figures for Gold Medals in the IRON NEST: Heavy Turret Simulator are not always visible on the mission screen. The game only displays the medal categories and not the specific numbers. Some of the requirements are also a little unusual, especially Average Accuracy, Triple Kill Time Window, Requisition Spent, and Kills Without Recon.
I checked the available medal requirements and player findings to put the exact Bronze, Silver, and Gold values in one place. I’ve also added useful tips for missions where the normal objective can conflict with a medal requirement.
How Gold Medals Work in IRON NEST?
Each mission may have a number of medals, and each medal has its own Bronze, Silver, and Gold thresholds.
Some requirements are simple. For example, the Allies Killed reward is given for keeping your friendly units alive. Others measure how efficiently you fire, how quickly you can get your first shot off, or how much requisition you use.
The main types of medal you will encounter in the game are as follows.
Allies Killed counts friendly units that die during the mission. It does not matter whether you were the one who killed them or whether another enemy was responsible for it. For Gold, you should aim for 0 allied deaths.
Enemies Killed counts enemy casualties during the mission. To get gold, you need to kill almost all the enemies in the mission.
Consecutive Kill Shots keeps a record of your kill streak. A miss or a non-lethal shell resets the streak to 0, so plan your shots carefully.
Kills-per-Shot Ratio measures the average number of kills you get per shot. In some missions, a minimum number of enemy kills is required before the ratio medal can count.
Requisition Spent works in the opposite direction on most missions. You need to spend less requisition to get the better medal. The exception is the Uncontested Front skirmish, which gives a reward for higher spending.
To get some Gold Medals, you need to fire quickly and keep your shots efficient. When the elevation computer is unavailable, you can still calculate the correct firing angle manually with the formula explained in our IRON NEST manual elevation calculation guide
Recons Requisitioned / Kills Without Recon requires you to kill enemies without buying aerial recon. If you spend requisition on a scout plane, this can invalidate this medal.
Seconds Until First Shot refers to the interval between the mission beginning and the moment you fire. Make it as quick as possible to have the Iron Nest loaded.
The Counter-Battery Time Left is determined by the timer shown above the paper rolls located at the back of the Iron Nest, and the higher the remaining time, the better medal you receive.
Kills With a Single Shell shows how many enemies you can kill with one shell, and it is available in the Uncontested Front skirmish.
Triple Kill Time Window tracks how fast you obtain three kill impacts. Although the precise method used by the game to calculate this statistic is not entirely clear, the listed thresholds are known.
IRON NEST: Gold Medal Requirements For All Missions
Calibration Fire
Calibration Fire has only one medal.
| Medal ID | Requirement | Bronze | Silver | Gold |
|---|---|---|---|---|
| shots_fired_1to3 | Shots fired, equal to or less than | 3 | 2 | 1 |
To get Gold, you must finish the mission with 1 shot or fewer.
The game also checks for zero shots as well, although there is no clear way to finish the mission without firing any shot.
Fire and Light
It also has only one medal.
| Medal ID | Requirement | Bronze | Silver | Gold |
|---|---|---|---|---|
| shots_fired_4to8 | Shots fired, equal to or less than | 8 | 6 | 4 |
For Gold, keep the total number of shots fired at 4 or fewer.
Liberation
Liberation has four medals.
| Medal ID | Requirement | Bronze | Silver | Gold |
|---|---|---|---|---|
| ally_kills_0to2 | Allies killed, equal to or less than | 2 | 1 | 0 |
| avg_accuracy_50to250 | Average accuracy, equal to or less than | 3 | 1 | 0.3 |
| kill_streak_3to6 | Consecutive kill shots, equal to or greater than | 3 | 5 | 6 |
| req_spent_30to100 | Requisition spent, equal to or less than | 100 | 65 | 30 |
At the start of the game, the 30 requisition Gold requirement seems impossible because your available shells cost a lot.
You can return to Liberation later after unlocking cheaper shell types. The DRIL shell is especially useful because it costs only 3 requisition once it has been unlocked.
There is also a helpful method for carrying out this mission: fire a STAR shell to P4, use the scout data obtained to triangulate the position, then use DRIL shells against known enemy positions. The second STAR shell can show additional targets, but do not use it between kills if you are going for the consecutive-kill medal because it can break your streak.
Another important point is the recon order in Liberation. The mission may request you to requisition a recon flight over P4, for 60 requisition points, thus making it impossible to achieve the Gold requisition objective on that mission. Alternatively, you can use one or two STAR shells together with Forward Observers to locate the target without purchasing the plane.
There are also reports that the Liberation gold-medal achievement may require all four Gold medals in one attempt. This is not clearly confirmed, but players have managed to get all four during the same run.
Counter-Battery
Counter-Battery has four medal requirements.
| Medal ID | Requirement | Bronze | Silver | Gold |
|---|---|---|---|---|
| three_kill_window_30to90 | Triple kill time window | 90 or less | 45 or more | 10 or more |
| counter_battery_100to260 | Counter-battery time left, equal to or higher | 100 | 200 | 260 |
| req_spent_30to100 | Requisition spent, equal to or less than | 100 | 65 | 30 |
| enemy_kills_6to10 | Enemies killed, equal to or more | 6 | 8 | 9 |
The listed Triple Kill Time Window values appear to contain an error in the game’s medal data. The mission documentation currently shows 90 or less for Bronze, 45 or more for Silver, and 10 or more for Gold.
The Gold enemy-kill target is also 9, not 10, despite the 6to10 medal ID suggesting otherwise.
For the Counter-Battery medal, keep the timer as high as possible. Do not wait around once the mission starts.
Iron Road
Iron Road has four medals.
| Medal ID | Requirement | Bronze | Silver | Gold |
|---|---|---|---|---|
| ally_kills_0to2 | Allies killed, equal to or less than | 2 | 1 | 0 |
| kill_streak_5to20 | Consecutive kill shots, equal to or greater than | 5 | 10 | 20 |
| kill_shot_ratio_0.8to2_10kills | Kills per shot, with at least 10 enemy kills | 0.8 | 1.5 | 2 |
| no_recon_with_kills | Kills without recon | — | — | — |
The most difficult part here is the 20-kill streak. You need to chain 20 lethal hits without missing or firing a non-lethal shell.
There was also some confusion about the number of targets in Iron Road. Player testing found 19 obvious enemy targets, including the five targets that leave the train after it reaches waypoint A, as well as the infantry and other targets in the town.
It doesn’t mean that you have to eliminate a fellow ally in order to meet the requirement. The exact number of targets can vary depending on what the mission spawns and on how the events play out.
Siege of Cartagena
| Medal ID | Requirement | Bronze | Silver | Gold |
|---|---|---|---|---|
| ally_kills_0to2 | Allies killed, equal to or less than | 2 | 1 | 0 |
| enemy_kills_6to15 | Enemies killed, equal to or greater than | 6 | 11 | 15 |
| no_recon_with_kills | Kills without recon | — | — | — |
| req_spent_50to180 | Requisition spent, equal to or less than | 180 | 100 | 50 |
To get Gold, you need 15 enemy kills, no allied deaths, and no recon for the relevant medal.
Spend requisition 50 or less for the Gold requisition medal.
The Gorge
| Medal ID | Requirement | Bronze | Silver | Gold |
|---|---|---|---|---|
| ally_kills_0to2 | Allies killed, equal to or less than | 2 | 1 | 0 |
| kill_streak_4to10 | Consecutive kill shots, equal to or greater than | 4 | 7 | 10 |
| enemy_kills_10to30 | Enemies killed, equal to or greater than | 10 | 20 | 30 |
| kill_shot_ratio_0.8to2_10kills | Kills per shot, with at least 10 enemy kills | 0.8 | 1.5 | 2 |
For Gold, you need 30 enemy kills, a 10-kill streak, and a 2.0 kills-per-shot ratio.
The ratio also requires at least 10 total enemy kills, so getting a good ratio with a few targets is not enough.
Rock of Gibraltar
| Medal ID | Requirement | Bronze | Silver | Gold |
|---|---|---|---|---|
| ally_kills_0to2 | Allies killed, equal to or less than | 2 | 1 | 0 |
| enemy_kills_1to2 | Enemies killed, equal to or greater than | 0 | 1 | 2 |
| no_recon_with_kills | Kills without recon | — | — | — |
| req_spent_10to30 | Requisition spent, equal to or less than | 30 | 20 | 10 |
Gold requires 2 enemy kills, 0 allied deaths, no recon for the relevant medal, and only 10 requisition or less.
The no-recon medal appears to be unreliable at the moment, so do not be surprised if the result does not match what you expected.
Dead Reckoning
| Medal ID | Requirement | Bronze | Silver | Gold |
|---|---|---|---|---|
| ally_kills_0to2 | Allies killed, equal to or less than | 2 | 1 | 0 |
| kill_streak_3to6 | Consecutive kill shots, equal to or greater than | 3 | 5 | 6 |
| enemy_kills_6to15 | Enemies killed, equal to or greater than | 6 | 11 | 15 |
| req_spent_30to100 | Requisition spent, equal to or less than | 100 | 65 | 30 |
For Gold, finish with 0 allied deaths, get 6 consecutive kills, kill 15 enemies, and spend less than 30 requisition.
Fire on Call
| Medal ID | Requirement | Bronze | Silver | Gold |
|---|---|---|---|---|
| ally_kills_0to2 | Allies killed, equal to or less than | 2 | 1 | 0 |
| enemy_kills_10to30 | Enemies killed, equal to or greater than | 10 | 20 | 30 |
| kill_shot_ratio_0.8to2_10kills | Kills per shot, with at least 10 enemy kills | 0.8 | 1.5 | 2 |
| no_recon_with_kills | Kills without recon | — | — | — |
To get Gold, get 30 enemy kills and a 2.0 kills-per-shot ratio, while keeping all allies alive and avoiding recon for the relevant medal.
High Tide
High Tide currently has an unusual medal setup.
| Medal ID | Requirement | Bronze | Silver | Gold |
|---|---|---|---|---|
| kill_streak_3to6 | Consecutive kill shots, equal to or greater than | 3 | 5 | 6 |
| three_kill_window_30to90 | Triple kill time window | 90 or less | 45 or more | 10 or more |
| avg_accuracy_50to250 | Average accuracy, equal to or less than | 3 | 1 | 0.3 |
| kill_streak_3to6 | Consecutive kill shots, equal to or greater than | 3 | 5 | 6 |
Yes, Consecutive Kill Shots appears twice.
That looks like a mistake in the current mission data. For now, the duplicate requirement does not create an additional challenge, so you have one less unique requirement to worry about.
The Average Accuracy stat is also not fully understood. The listed Gold value is 0.3, but the game’s normal shot accuracy display uses percentages. The internal stat may be measuring something different from the accuracy percentage shown during the mission.
Blind Fire
| Medal ID | Requirement | Bronze | Silver | Gold |
|---|---|---|---|---|
| req_spent_50to180 | Requisition spent, equal to or less than | 180 | 100 | 50 |
| kill_streak_3to6 | Consecutive kill shots, equal to or greater than | 3 | 5 | 6 |
| enemy_kills_5to20 | Enemies killed, equal to or greater than | 5 | 10 | 20 |
| no_recon_with_kills | Kills without recon | — | — | — |
For Gold, kill 20 enemies, reach a 6-kill streak, spend 50 requisition or less, and avoid recon for the relevant medal.
Phantom Battery
| Medal ID | Requirement | Bronze | Silver | Gold |
|---|---|---|---|---|
| no_recon_with_kills | Kills without recon | — | — | — |
| enemy_kills_6to10 | Enemies killed, equal to or more | 6 | 8 | 9 |
| avg_accuracy_50to250 | Average accuracy, equal to or less than | 3 | 1 | 0.3 |
| counter_battery_100to260 | Counter-battery time left, equal to or higher | 100 | 200 | 260 |
Gold requires 9 enemy kills, 0.3 or less Average Accuracy, and 260 seconds or more remaining on the counter-battery timer.
Final Harvest
| Medal ID | Requirement | Bronze | Silver | Gold |
|---|---|---|---|---|
| ally_kills_0to2 | Allies killed, equal to or less than | 2 | 1 | 0 |
| no_recon_with_kills | Kills without recon | — | — | — |
| enemy_kills_10to30 | Enemies killed, equal to or greater than | 10 | 20 | 30 |
| first_shot_fast_with_kills | First shot time, with enemy-kill requirement | 120 | 80 | 50 |
To get Gold, you must have 30 enemy kills, no allied deaths, and fire your first shot within 50 seconds.
Load your first shell immediately when the mission starts. You can aim while the loading animation is running, so there’s no need to spend the first few seconds trying to align your shot before you start to load.
White Shells Endings
Instead of just requiring medals, the White Shells mission has four possible endings.
Player testing has clarified that you do not always need the exact shell originally listed for an ending. What matters is the shell category and the place where the shell lands.
Ending 1 – Peaceful Shell
Use a peaceful shell, such as:
- Propaganda
- Smoke
- STAR
The shell doesn’t need to strike a target. It only needs to land inside the city borders.
Ending 2 – Non-Lethal Shell
Use a non-lethal shell, such as:
- Tear Gas
- Other gas-type shells
Again, the shell does not have to hit an enemy. A landing inside the city borders will trigger the ending.
Ending 3 – Destroy the Allied Artillery
For this ending, you need to destroy all Allied artillery.
This one does not follow the peaceful/non-lethal/lethal shell grouping used by the other endings.
Ending 4 – Lethal Shell
Use any lethal shell, such as:
- DRIL
- HE
- AP
- Other lethal shell types
The shell can hit any location inside the city borders. It does not have to directly hit a target.
Skirmish – Challenge – Counter Battery Timer
The Counter Battery Timer challenge currently has these known requirements:
| Medal ID | Requirement | Bronze | Silver | Gold |
|---|---|---|---|---|
| no_recon_with_kills | Kills without recon | ? | ? | ? |
| first_shot_fast_with_kills | First shot time + enemy-kill requirement | 120 | 80 | 50 |
| kill_shot_ratio_0.8to1.5_20kills | Kills per shot, with at least 20 enemy kills | 0.8 | 1.2 | 1.5 |
| kill_streak_5to20 | Consecutive kill shots | 5 | 10 | 20 |
The exact Kills Without Recon values are still unknown.
For Gold, aim for a 1.5 kills-per-shot ratio, kill at least 20 enemies, and maintain a 20-kill streak.
Skirmish – Chill – Uncontested Front
| Medal ID | Requirement | Bronze | Silver | Gold |
|---|---|---|---|---|
| kill_shot_ratio_0.8to1.5_20kills | Kills per shot, with at least 20 enemy kills | 0.8 | 1.2 | 1.5 |
| kill_streak_5to20 | Consecutive kill shots | 5 | 10 | 20 |
| req_spent_high_150to600 | Requisition spent, equal to or greater than | 150 | 350 | 600 |
| single_impact_kills_2to5 | Kills with a single shell, equal to or greater than | 2 | 3 | 5 |
To aim for Gold, you need to spend at least 600 requisition, reach a 20-kill streak, maintain a 1.5 kills-per-shot ratio, and kill 5 enemies with a single shell.
So don’t try to save requisition on this mission.
Quick IRON NEST Gold Medal Reference
The most important Gold targets are:
| Mission | Gold requirements |
|---|---|
| Calibration Fire | 1 shot or less |
| Fire and Light | 4 shots or less |
| Liberation | 0 allies killed, 0.3 accuracy stat, 6-kill streak, 30 requisition or less |
| Counter-Battery | 10-second triple-kill window, 260+ counter-battery time, 30 requisition or less, 9 kills |
| Iron Road | 0 allies killed, 20-kill streak, 2.0 kills/shot with 10+ kills |
| Siege of Cartagena | 0 allies killed, 15 kills, no recon, 50 requisition or less |
| The Gorge | 0 allies killed, 10-kill streak, 30 kills, 2.0 kills/shot |
| Rock of Gibraltar | 0 allies killed, 2 kills, no recon, 10 requisition or less |
| Dead Reckoning | 0 allies killed, 6-kill streak, 15 kills, 30 requisition or less |
| Fire on Call | 0 allies killed, 30 kills, 2.0 kills/shot, no recon |
| High Tide | 6-kill streak, 10-second triple-kill window, 0.3 accuracy stat |
| Blind Fire | 50 requisition or less, 6-kill streak, 20 kills, no recon |
| Phantom Battery | 9 kills, 0.3 accuracy stat, 260+ counter-battery time, no recon |
| Final Harvest | 0 allies killed, 30 kills, first shot within 50 seconds, no recon |
| Counter Battery Timer | 20-kill streak, 1.5 kills/shot with 20+ kills, first shot within 50 seconds |
| Uncontested Front | 20-kill streak, 1.5 kills/shot with 20+ kills, 600+ requisition, 5 kills in one shell |
Some of the medal values are clearly the result of incomplete or wrong mission data. High Tide has a duplicate kill-streak medal, Counter-Battery seems to have an incorrect description for a triple kill, and the Rock of Gibraltar recon medal might not function properly. If a medal fails to activate even though you have met the stated requirement, keep these problems in mind.
When the requirements for a mission are very strict, wait to carry out those missions until you have obtained cheaper shells; specifically, the DRIL shell can make some of the early Gold requirements seem much more realistic.
