Every gold medal in Iron Nest Heavy Turret Simulator requires you to destroy all enemy targets within the mission’s time limit while keeping your turret’s hull integrity above 50%. You enter the mission, pick your turret loadout, and fight through waves of ground and air units; the medal is awarded at the results screen if you meet those two conditions. Below is the full breakdown of how the medal system works, what affects your chances, and how to plan for each mission type.
How the Medal System Works
Iron Nest Heavy Turret Simulator grades each mission on three criteria: completion time, damage taken, and accuracy. Gold requires you to finish under the par time for that mission, lose no more than 50% of your hull, and maintain at least 70% shot accuracy. The game tracks these stats automatically, and the results screen shows a gold, silver, or bronze emblem based on your performance. Silver typically allows up to 75% hull damage and 50% accuracy, while bronze only requires you to survive to the end.
The par time varies by mission and difficulty. On Normal difficulty, most missions have a par time between 8 and 12 minutes. Hard missions give you less time and tougher enemies, while Nightmare missions require near-perfect execution. The game does not show the exact par time before you start, but you can estimate it from the mission briefing’s suggested loadout and enemy count.
Mission Types and Their Specific Requirements
Each mission type has its own gold medal threshold, and knowing them helps you prepare. The main categories are:
- Defense missions: Hold a fixed position against waves. Gold requires you to destroy all enemies before the final wave timer expires, usually 10 minutes.
- Escort missions: Protect a slow-moving convoy. Gold demands the convoy takes no more than 20% damage and you finish within the 12-minute limit.
- Boss missions: Single powerful enemy. Gold requires you to kill the boss in under 6 minutes while taking less than 30% hull damage.
- Swarm missions: Hundreds of small, fast enemies. Gold needs you to eliminate 95% of the swarm and finish before the 15-minute cap.
These are the general patterns, but the exact numbers can shift with game updates. Always check the mission briefing for the specific medal conditions listed under the rewards tab.
Loadout Choices That Help You Earn Gold
Your turret’s weapon loadout directly affects your ability to meet the gold criteria. For most missions, a balanced setup works best:
- One rapid-fire cannon for infantry and light vehicles.
- One high-damage sniper or railgun for heavy armor and bosses.
- One anti-air missile launcher if the mission includes aircraft.
Upgrade your reload speed and heat dissipation first, because downtime is your biggest enemy. Accuracy upgrades are also valuable, as they reduce spread and help you hit the 70% accuracy threshold. Avoid using explosives on small targets—they waste ammo and lower your accuracy score.
Common Mistakes That Cost You Gold
Many players miss gold because of a few recurring errors. The most common is focusing on damage output over accuracy. Spraying bullets everywhere might kill enemies, but it tanks your accuracy stat. Another mistake is ignoring the minimap—enemies that flank you can damage your hull without you noticing, pushing you below the 50% threshold. Finally, some players try to finish too fast and skip enemies, which fails the “destroy all targets” requirement. Always prioritize clearing the field over speed.
Also, don’t forget to repair your turret between waves if the game allows it. Some missions have repair stations that restore hull integrity; using them can save a gold run.
How to Read Your Results Screen
After each mission, the results screen shows three bars: Time, Damage, and Accuracy. Each bar has a colored marker indicating the gold, silver, or bronze threshold. If your time bar is in the gold zone but your damage bar is in silver, you get silver overall. The medal is determined by the lowest of the three criteria. So even if you finish fast, one bad hit can drop you to silver. The screen also shows your total score, which is a weighted sum of the three factors, but the medal is what matters for unlocks.
Comparing Gold Requirements Across Difficulties
Gold on Normal is significantly easier than on Hard or Nightmare. On Normal, you can often finish with 30 seconds to spare and still get gold. On Hard, the par time is roughly 20% shorter, and enemies deal 50% more damage. Nightmare cuts the par time by 40% and enemy damage is doubled. The accuracy requirement stays the same across difficulties, but the faster enemy movement makes it harder to hit. If you’re struggling, practice on Normal to learn enemy patterns, then move up.
Costs and Unlocks Tied to Gold Medals
Earning gold medals is the primary way to unlock new turrets, weapons, and cosmetic skins. Each mission has a set of rewards: bronze gives you a small amount of credits, silver gives you a weapon blueprint, and gold gives you a unique turret chassis or a rare mod. Some missions require you to earn gold on all previous missions to unlock the next area. There is no in-game currency cost to attempt a mission, but failing costs you time and maybe repair credits if you lose your turret.
Safety and Fair Play Notes
Iron Nest Heavy Turret Simulator is a single-player game, so there’s no competitive safety concern, but be aware that some mods or cheats can corrupt your save file. The game’s anti-cheat system may flag modified stats, and using third-party tools could result in losing your progress. Also, the game has a built-in pause feature—use it if you need to step away, as leaving the game running can cause your turret to take damage while you’re away.
Frequently Asked Questions
Do I need to get gold on every mission to unlock the final boss?
Yes, the final boss mission is locked until you earn gold on all previous missions in the campaign. Silver or bronze will not unlock it.
Can I replay a mission to improve my medal?
Absolutely. Replaying missions is encouraged, and your best medal per mission is saved. You can replay any mission from the mission select screen.
Does the difficulty setting affect the gold medal requirements?
Yes. Higher difficulties have shorter par times and tougher enemies, but the gold rewards are the same. Some players prefer to earn gold on Normal first, then challenge Hard for extra credits.
What happens if I finish the mission but my hull is below 50%?
You will not get gold, even if you destroyed all enemies and finished under the time limit. You’ll receive silver or bronze depending on how much damage you took.
Is there a way to see the exact par time before starting a mission?
Not directly. The game only shows a vague “time limit” in the briefing. However, community guides and your own experience will help you estimate it.
Does accuracy include shots that miss due to enemy dodging?
Yes, any shot that doesn’t hit a target counts as a miss. Enemy dodging is part of the challenge, so you need to lead your shots and time your fire.
