Iron nest: heavy turret simulator wiki

About the game

IRON NEST: Heavy Turret Simulator is a dieselpunk heavy-artillery game developed and published by Nick Nieuwoudt and Dominik Latos. It launched on Aug 6, 2026 and sells for $14.99. Blending Action, Indie, and Simulation genres, it puts you inside a colossal war machine and makes you do the math: read incoming coordinates, take map measurements, work the hydraulics, and gunlay each shot before pulling the trigger.

"Take map measurements based on the received coordinates, strain the hydraulics, and gunlay the cannons to unleash devastating blows."

This is strictly a single-player experience. There is no co-op and no multiplayer, so every ranging shot, wind correction, and counter-battery duel rests entirely on you. The game ships with 33 Steam Achievements,Steam Cloud saves, and Family Sharing, plus full controller support including DualShock and DualSense controllers.

Key features to know before your first mission:

• Coordinate-driven gunlaying: You receive target coordinates, then measure the map yourself before setting elevation and traverse.
• No timed input pressure: The game is explicitly playable without timed input, so slow, deliberate calculation beats speed.
• Missions with real stakes: Campaigns range from Calibration Fire and Counter-Battery to sieges like Siege of Cartagena and Rock of Gibraltar.
• Accessibility options:Color Alternatives and Custom Volume Controls help with visibility and audio comfort.
• Surround and stereo sound: Audio cues matter when spotting incoming fire on the battlefield.

Getting started

Your first hours in IRON NEST are about learning one core ritual:receive coordinates, measure the map, align the gun, strain the hydraulics, and fire. The game never forces a timer on you, but it does reward precision, and the medal system tracks how cleanly you execute every mission.

Use this checklist for your first session:

• Start with Calibration Fire. It teaches the full firing sequence and unlocks the Just Calibrating achievement when you land the calibration round.
• Practice reading the map and correlating received coordinates before touching elevation or traverse. Measurement mistakes are the most common cause of a wasted shell.
• Spend a few missions building muscle memory for the hydraulic and gunlaying controls before attempting gold medals.
• Verify your PC against the minimum requirements before diving into long missions. A dedicated GPU is strongly recommended.

On the hardware side, the minimum specs target an average of 30 FPS at 720p on low settings using an Intel Core i5-4460 or AMD FX-8350,4 GB RAM, and Intel UHD or AMD Vega 8 graphics. For a smoother experience, the recommended specs call for an Intel Core i5-8400 or AMD Ryzen 5 2600,8 GB RAM, and an NVIDIA GTX 1060 6GB or AMD RX 580 8GB. Both tiers require 5 GB of storage and a 64-bit operating system with DirectX 10.

After your first successful fire mission, shift your focus to the medal system. Achievements like Duty Fulfilled(gold on all medals in Calibration Fire),Iron Discipline(gold in Fire on Call), and Master Gunner(gold in Phantom Battery) demand consistent, careful shooting. Replaying earlier missions with fresh eyes after you understand the ballistics will get you further than rushing into new operations half-trained.
