IRON NEST: Heavy Turret Simulator

Command a 5,000-ton dieselpunk artillery fortress in alternate-history 1920s Spain. You never see the battlefield — you read teleprinter orders, triangulate coordinates on a paper map, crank the hydraulics, and fire blind. Every lever, dial and shell is yours to manage.

Your IRON NEST Journey

  1. 1

    Beginner Guide

    From your first teleprinter order to your first hit: cockpit layout, station routine, and the standard sequence for a single fire mission.

  2. 2

    Triangulation & Firing Solutions

    How two observer bearings cross into a target coordinate, and how that becomes bearing, elevation and charge. The wall most operators hit in their first two hours.

  3. 3

    Counter-Battery Survival

    What to do when enemy fire direction centres start ranging on you: pre-computed fire plans, bearing-sorted target batches, and using each FDC kill as a working pause.

  4. 4

    Firing Solution Calculator

    Cross two observer bearings, then re-measure from the nest. Shows exactly how far off a shot lands if you copy the observer's bearing straight onto the gun.

What is IRON NEST: Heavy Turret Simulator?

IRON NEST is a first-person heavy-artillery simulator that locks you inside a 5,000-ton dieselpunk mobile gun platform. It is not an action game — you cannot see outside the nest, and you fight using teleprinter tape, a paper map, a protractor and a wall of gauges.

Receiving High Command's orders, plotting targets by triangulation, computing firing solutions, hand-loading more than thirty shell types, repairing hydraulic lines and answering enemy counter-battery fire are all done by you. Set in alternate-history 1920s Spain, with fifteen operational regions, over a hundred medals and procedurally generated objectives for near-endless replayability.

Frequently asked

  • Is IRON NEST multiplayer?

    The 1.0 release ships as a single-player campaign. Developer statements about a second, multiplayer-first title are easy to misread as a promise about this one — treat any co-op roadmap claim as unconfirmed until confirmed in the official FAQ or a developer post.

  • Do I need to be good at maths?

    You need to be careful, not fast. Every calculation is arithmetic you could do on paper; the difficulty is transcription discipline under a clock, which the triangulation drill covers.

  • Will the free demo teach me the real game?

    Yes. The demo runs the same fire-control loop with procedurally generated objectives, so every drill on this site can be practised before purchase.
