Unofficial Field ManualWhat Is IRON NEST?
IRON NEST: Heavy Turret Simulator is a dieselpunk heavy-artillery simulation about manually operating a colossal war machine. Gunnery sits inside a larger strategic structure. The Operator receives orders, records useful information, works with the tactical map, uses the in-game ballistic calculator, prepares the turret, fires, and reviews the operation.
This homepage keeps that overview brief. Start Here explains the complete sequence. The system guides cover map reading, ballistics, and the fire-control handoff in more detail. Missions separates the story Campaign from the replay-focused Challenge Missions, where the developer describes varied targets, progression, unlockable ammunition and reconnaissance abilities, and Steam leaderboards.
Game Facts at a Glance
Steam lists Nick Nieuwoudt and Dominik Latos as the developers and publishers. The Windows release arrived August 6, 2026 and is currently listed as single-player. Multiplayer for Heavy Turret Simulator has been announced for the future, but there is no confirmed release date. Steam also carries a separate Windows single-player demo, released June 15, 2026.
On July 10, 2026, the developer announced IRON NEST as playable on Steam Deck and linked a feedback form. That is a dated developer statement. It is not a performance assessment by this site.

Tools for the Current Task
The browser-local Mission Checklist is a simple memory aid for the operating sequence. It records the stages you mark in that browser; it does not read the game or decide whether a setup is correct. Use it when you have moved between stations and want to see where you paused.
The Mils to Degrees Converter handles pure angle arithmetic under a selected convention. It contains no target, ammunition, map, or ballistic data. Reviewed game material uses degrees and does not document mil input, so the converter cannot produce an IRON NEST firing solution.
Choose Your Route
Open Start Here for a compact explanation of the operating sequence. Tactical Map covers map reading and measurements. Ballistics separates elevation, bearing, distance, and powder charge, while Fire-Control Computer focuses on the handoff from map work to gun preparation.
Choose Missions for a Campaign-versus-Challenge overview. Visit Demo for the separate Steam listing and the limits of the available comparison. Patch Notes summarizes dated developer posts, and Troubleshooting organizes developer-listed issue information. Each route handles one question, so you can leave the homepage as soon as you find the right path.

The developer FAQ starts the loop with teleprinter orders. Notes carry relevant details into tactical-map work. Map measurements then enter the in-game ballistic calculator, whose named output is required gun elevation. Ammunition and powder charges are prepared before turret elevation and rotation, arming, and firing.
The operation continues after the shot. Objectives are completed, then a newspaper reviews the mission and wider events before the next assignment. A requisition console supports progression between assignments. For the expanded version, use Start Here; the homepage only gives the sequence enough context to choose the next guide.
Current Status
The reviewed Steam release is version 1.0 and currently single-player. Steam Workshop support is being seriously considered, and the developer says preliminary tools may be in development. Workshop support has not been promised, and no implementation date has been given.
The August 10, 2026 US listing paired the $19.99 standard price with a $14.99 introductory offer, a 25% reduction. Its label gave August 20 as the end date. Regional prices can differ; Steam shows the live amount.
Latest from the Developers
The latest item in the frozen August 10 Steam News snapshot is IRON NEST - PATCH 1.0 (1577), published August 10, 2026. The developer lists fixes for cursor behavior, replay and turret resets, localization, and other identified issues. The post also notes work on error reporting, resource use, some crashes, crater visuals, and an ultrawide stopwatch-offset setting.
Patch Notes collects these dated records, links the original posts, and summarizes the changes attributed to each build.
