This guide lists the hidden Gold medal requirements for missions in IRON NEST: Heavy Turret Simulator, which are not clearly explained in-game. Gold medals generally demand stronger accuracy, fewer allied casualties, limited spending and more efficient kills.

– Calibration Fire: fire no more than one shot.
– Fire and Light: fire no more than four shots.
– Liberation: kill no allies, maintain 0.3 average accuracy or lower, achieve six consecutive kill shots and spend 30 requisition or less.
– Counter-Battery: complete a triple kill within 10 seconds, retain 260 counter-battery time, spend 30 requisition or less and kill at least nine enemies.
– Later missions add similar Gold targets, typically requiring no allied deaths, 15–30 enemy kills, limited or no reconnaissance, and stringent requisition limits.
