IRON NEST: Heavy Turret Simulator — Everything We Know So Far
A complete primer on IRON NEST: Heavy Turret Simulator — the dieselpunk heavy-artillery sim where you operate a 5,000-ton turret. Setting, gameplay loop, ammo, regions, release window and more.
IRON NEST: Heavy Turret Simulator is one of the more unusual war games on the horizon: instead of putting you in the boots of an infantryman, it locks you inside a single, monstrous artillery turret and asks you to actually operate it. It’s brutal, methodical, and unapologetically mechanical. Here’s a grounded overview of everything that’s been shown or confirmed so far — with anything still uncertain clearly flagged as expected.
The one-line pitch
You command a colossal dieselpunk war machine and dominate the battlefield from inside it. Every lever, dial and shot is yours. High Command radios orders down the chain — but the chain ends at your fingertips, and you decide which orders to follow.
The setting
The game is set in an alternate-history Spain in the late 1920s, with the country on the brink of civil war: a monarchy clinging to power while a republican uprising spreads. That backdrop gives IRON NEST its dieselpunk texture — riveted steel, oil and brass, teleprinters and propaganda — without leaning on a real conflict.
How a shot actually works
The core loop is what makes IRON NEST stand out. A single shot is a small procedure:
- Monitor the wire. Calibrate the teleprinter and watch radio traffic for incoming orders and coordinates.
- Turn intel into a plan. Read the intelligence reports and decide on a target.
- Measure the map. Use the tactical map to take measurements from the coordinates you’ve been given.
- Solve the problem. Feed range and bearing into the ballistic calculator to find your firing solution.
- Load and lay. Pick a shell, set the propellant charge, then traverse and elevate the gun by hand.
- Fire — then check your work. Send the round downrange and review aerial photos of the result.
If that sounds closer to a logic puzzle than a shooter, that’s the point. See our first firing solution walkthrough for a step-by-step.
What’s in the box
Based on the Steam listing and demo, the full game is expected to include:
- 30 unlockable ammunition types, from armor-piercing rounds to smoke and chemical shells
- 20 unlockable abilities that expand what your crew and machine can do
- 15 regions across the campaign
- 8 challenge modes plus leaderboards for replay value
- Procedurally generated objectives layered on top of a handcrafted story
- Newspaper reports that reflect the consequences of your fire
Who’s making it
IRON NEST is a two-person passion project from Nick Nieuwoudt and Dominik Latos. Despite the tiny team, it crossed 10,000 wishlists with essentially no marketing budget — a strong early signal for a niche simulator.
Release window
The team is aiming for a Q3 2026 launch, described as expected late July / early August 2026, on PC via Steam. A free demo is already live. We track every update on the news page, and you can read more about timing in our release date guide.
Frequently asked questions
What kind of game is IRON NEST?
It's a first-person, dieselpunk heavy-artillery simulator. Rather than running around a battlefield, you stay inside one colossal turret and operate it by hand — reading intel, calculating a firing solution, loading the right shell, and pulling the trigger on a 5,000-ton machine.
When does IRON NEST release?
The developers are targeting a Q3 2026 launch, which they have described as expected late July or early August 2026. A public demo is already available on Steam. Treat the exact day as unconfirmed until the team announces it.
Is there an IRON NEST demo?
Yes. A free demo launched during Steam Next Fest and remains downloadable from the game's Steam page. It's the best way to learn the firing loop before the full release.
