Iron nest: heavy turret simulator achievements

Achievement overview

IRON NEST: Heavy Turret Simulator features 33 Steam achievements in total, and the complete set can be unlocked on your own. The game is a single-player artillery simulation built around taking map measurements from received coordinates, straining the hydraulics, and gunlaying the cannons for destructive fire. There is no multiplayer or co-op, so none of the achievements depend on other players. The game also supports Steam Cloud, which keeps your save and unlock progress synced between machines.

The achievement list is roughly split into two kinds of unlocks. Most progression achievements pop when you finish a named operation in the campaign, while the medal achievements push you to earn gold on all medals within a given operation. Four achievements stand out because their descriptions describe a city's fate rather than a military objective, which suggests some missions have branching outcomes worth exploring.

• Progression achievements
  • unlocked by completing core operations from the early
  Calibration Fire through the late-campaign battles.
• Gold medal achievements
  • one for each of
  15 operations, requiring gold standards across every medal category in that mission.
• City outcome achievements
  • four flavour-heavy unlocks that appear tied to a city being destroyed, spared, subdued, or celebrated.

Tips for completionists

Approach the set in two passes. On the first pass, play through every operation to grab the story and progression achievements and to learn where each target appears. On the second pass, replay each mission to tighten your gunnery and secure gold medals. The Calibration Fire is the ideal place to learn the game's aiming model, since it is short and forgiving enough for experimentation.

1. Clear every operation once to unlock all progression achievements and learn each map.
2. Return for gold medals operation by operation. Use a calibration shell to confirm your solution before firing for effect.
3. Replay for city outcomes after the medals are done, and vary how you complete each mission to trigger the alternate city endings.

The toughest gold medals tend to be in operations with hidden or counter-firing enemy batteries. The Counter-Battery,Blind Fire, and Phantom Battery missions in particular reward careful map measurements and quick reactions. Do not be afraid to restart a mission if your opening shots miss badly, since a single poor salvo can be enough to drop your medal grade.

• Precision beats volume: medal grading rewards clean, deliberate fire over rapid sloppy salvos.
• Restart early: resetting a mission is faster than carrying a flawed run to the end when chasing gold.
• Track your remaining unlocks: with 33 achievements, a simple progress sheet helps you spot which operations still need a perfect run.
