FILE 02 · DEMO INTELLIGENCE · UNOFFICIAL
The demo and the full 1.0 release are two separate Steam builds. This page holds both files side by side: what each one is officially confirmed to contain, what is only visible in footage, and what nobody has confirmed yet — each line dated and sourced.
LAST VERIFIED 2026-08-10 · DEMO APP 4300500 · PARENT 2950790 · DEM-007
The Iron Nest demo is still listed on Steam as a free demo of IRON NEST: Heavy Turret Simulator and can be installed from that page without buying anything. Use it to try the fire-control loop, the controls, and how the game runs on your own PC. The current official demo page lists two challenge modes, 30 ammo types and abilities combined, 15 regions and 100+ unlockable medals. A launch-period recording published on 2026-06-16 shows four campaign missions: Calibration Fire, Fire & Light, Liberation and Counter-Battery. It also shows Uncontested Engagement leading to a Chill Mode dialog that calls it a replayable sandbox mission. Because the footage has no visible build number and predates a later Demo build, the current-build mission list, complete itemized loadout and any separately named Sandbox mode remain unresolved. In addition, no official source confirms that demo progress carries into the full 1.0 game. Pre-1.0 developer comments about demo scope are kept as historical context only. Every line below carries its evidence level and the date we last checked it.
The demo installs from its own official Steam app page. Steam is the route we verified and the only download route this site links; we do not verify third-party files, launchers or mirrors.
▲ For the lowest-risk install path, use the official Steam listing. We do not link cracked builds, third-party file hosts or unverified download packages.
A complete recording published on 2026-06-16 shows the four campaign mission titles below. No build number is visible, and the recording predates the later Demo build dated 2026-06-30, so this is an observed launch-period sequence rather than a promise about the current download.
Looking beyond this Demo evidence? Use the verified full-game Campaign mission order.
MISSION DETAIL · LAUNCH-PERIOD VIDEO
A guide recording shows an HE triangulation phase followed by Star Shell illumination over the royal palace. The second phase uses impact recon photos to correct the burst position; the recording has no visible build number.
MODE MECHANIC · HISTORICAL DEVELOPER REPLIES
Pre-release developer replies describe three FDCs: destroying one pauses the timer and creates a planning window for the next salvo. A current community guide reports the same mechanic, but the exact current menu title is not officially confirmed.
OBSERVED MODE LANGUAGE
The same recording shows a dialog describing Chill Mode as a replayable sandbox mission with no end or objectives. It does not show a separate main-menu mode named Sandbox.
Each row states what is known about each build, not what is likely. Where the audited official sources do not settle a field, the cell says so instead of carrying an estimate — and the annotation names the evidence that would change it.

The demo uses the same receive-measure-calculate-load-aim-fire loop described for the full game. If deliberate, instrument-led shooting is not your pace, the demo reveals that before purchase.
◆ OFFICIALLY CONFIRMED
Installing the demo is a real test of whether the engine starts and holds a frame rate on your hardware. It is not a benchmark of the full game.
□ NOT OFFICIALLY CONFIRMED
Steam declares full controller support and 15 interface languages for the demo. Use the free build to check real controller behaviour and interface readability on your own setup.
◆ OFFICIALLY CONFIRMED
These are the questions people ask most, and the ones the audited official sources do not answer yet. Each one names the evidence that would close it — send it to us and it gets logged, checked and dated.
No official statement confirms that saves, unlocks or medals move into the full game.
EVIDENCE NEEDEDA developer reply, or a documented test showing demo progress before and after installing 1.0.

The video shows HE Shell, AP Shell, Star Shell and Powder Charges as examples. The complete item list and the ammo/ability split are still not published.
EVIDENCE NEEDEDA complete requisition/loadout capture from the current demo build.
Steam declares controller and accessibility categories, but real remapping, subtitle and text-scaling behavior is not verified here.
EVIDENCE NEEDEDCurrent-build options captures plus a short controller/remapping and readability check.
No evidence supports a performance-parity claim between the demo and the full game.
EVIDENCE NEEDEDSame device, same settings, same scene, recorded for both builds.
Try the demo if you are new to turret and fire-control simulation, or you are unsure whether the pace suits you.
Try the demo to check performance, controller support or text readability on your own machine before buying.
You already own the full game and want an item-by-item omission list. The official pages publish headline counts, not a complete manifest.
You are here for multiplayer, console or VR. The current Steam products are listed as single-player Windows builds; announced future plans are tracked on the roadmap.
For current Iron Nest multiplayer and co-op status, use the multiplayer guide. Console and VR plans remain on the full roadmap.
Setup and orientation only. This is not a mission solution, and none of it is written from our own play session — mission-level guides will live on their own pages when they are ready.
Use the Steam demo app linked here. This site does not verify or link third-party files, launchers or mirrors.

Steam lists 15 interface languages plus declared accessibility categories. Check the in-game options against your own readability needs.
Steam declares full controller support; verify controller or mouse-and-keyboard behaviour in the options screen before an engagement.
The official loop is orders, map measurements, firing-solution calculation, ammunition and charge selection, elevation, rotation and firing.
Ranging and correcting once is more informative than firing quickly several times.
That figure is evidence for your own hardware only, not proof of full-game performance parity.
A screenshot with a visible build number and capture date makes an observation auditable.
DECLARED BY THE STORE PAGES
System requirements, supported languages and controller support are published per app. Read the demo page and the full game page separately — the two builds do not necessarily share one specification.
WHAT ONLY YOU CAN MEASURE
Frame rate on your hardware, whether the interface text is readable at your distance, whether your controller maps the way you expect, and how long a session stays comfortable. We publish no performance comparison between the two builds, because no evidence supports one.
□ NOT OFFICIALLY CONFIRMED
Yes. The demo is a free Steam demo app and needs no purchase. The full game is a paid product; check its official Steam store page for the current price and discounts because they vary by region and over time. We last checked the listings on 2026-08-10.

It runs the same heavy-turret fire-control loop as the full game. The current official demo page lists two challenge modes, 30 ammo types and abilities combined, 15 regions and 100+ unlockable medals. The exact current campaign slice and complete itemized loadout remain unconfirmed.

A launch-period recording published on 2026-06-16 shows four campaign missions: Calibration Fire, Fire & Light, Liberation and Counter-Battery. It has no visible build number and predates a later Demo build, so the current Demo mission count is not officially confirmed.

Launch-period footage shows Uncontested Engagement opening a Chill Mode dialog that describes it as a replayable sandbox mission with no end or objectives. The footage and audited official sources do not show a separate menu mode named Sandbox.

Developer replies dated 2026-02-24 and 2026-03-03 described Challenge Mode with three FDCs: destroying an FDC paused the timer so the player could plan the next salvo. A current community guide reports the same mechanic. Because the developer replies predate the Demo release and no current menu capture is in the audited evidence set, the exact current menu title is not officially confirmed.

No. The demo is a separate Steam app, and third-party Steam metadata records a different depot and public Build ID for each app. The full game launched as a single-player 1.0 release on 2026-08-06. They share the core loop, but the exact demo campaign slice is not published.

There is no official confirmation that it does. We found no transfer statement on either store page or in the announcements, and no source that rules it out either, so this stays not officially confirmed.

Yes, as a first check that the engine runs on your hardware. It is not proof that the full game performs identically — no source supports a parity claim between the two builds.

We have not played either build ourselves. Everything here is read from official pages, dated footage or player reports, and labelled accordingly — a streamer’s recording is never written up as our own test.
Stated on an official Steam page, announcement or current developer reply.
Two or more independent records agree on the same conclusion.
Observed in dated third-party platform metadata. Useful for technical records, not gameplay conclusions.
Visible in recorded footage of a dated build. Not a developer promise, and not our own play session.
Reported by players. Used to find questions, never as the only basis for a fact.
A pre-1.0 or superseded statement kept for context. It does not override the current build.
No answer was found in the audited official source set as of the last-checked date.
Sources disagree. Both readings stay on the page until an official source settles it.
