About the Game
A brutal dieselpunk heavy-artillery simulator where you dominate the battlefield through a colossal war machine. Every lever, every dial, and every shot is under your control. High Command may send its orders, but the chain of command ends at your fingertips. They don't carry consequences. You do, Operator.
MAKE EVERY SHOT COUNT.
The teleprinters are calibrated to monitor local radio traffic. One delivers TOP-PRIORITY directives from High Command. The other relays direct calls from the frontline. Remember: every piece of information can determine the success of the entire operation.
Transform intelligence reports into a battle plan, get aerial photos that reveal the outcome of your actions, and watch your barrels reshape the landscape. The map isn't here just for measurements. It's also your window to the battlefield. Make no mistake. You can move the markers, but the scars remain.
Hammer the measurements, crank the numbers, and watch the ballistic calculator grind toward firing solutions. Drive the charges higher to blast shells across the horizon, or dial it back to arc them deliberately into enemy emplacements.
Beware: the machine may fail. You must not.
Breach bunkers with armor-piercing rounds, screen friendly withdrawals with smoke, and ████ █████████ with phosgene gas. It never happened if there are no witnesses. Every shell is forged for a single purpose, and whatever you choose will echo across the battlefield long after the smoke clears.
Haul the elevation wheel and watch the guns climb under your command. Match it with the exact propellant charge, or a surgical strike will turn into an avoidable mess. Precision is everything because neither flawless paperwork nor the finest propaganda will erase your guilt.
Drag the heavy lever and feel the entire structure shudder beneath your feet. A machine like IRON NEST doesn't spin on a whim. It takes time to swing that much iron with grace. Skilled Operators use that time to handle other tasks. After all, the coffee machine on your desk is there for a reason.
Pull the trigger, and let thousands of tons of machinery answer your call. Feel the turret recoil and watch the frontline crumble under the weight of steel. Once the dust settles, only silence remains, hanging heavy in the air, and the moment new orders arrive, it all begins again.

Setting
The campaign is set in alternate-history Spain in the late 1920s, on the brink of a civil war. In this timeline, the monarchy still holds power, and a republican uprising is spreading across the country.
The Team
IRON NEST is a two-person passion project from Nick Talmers (development) and Dominik Latos (propaganda). With 20+ years of combined experience and a lifelong obsession with artillery, interwar machinery, and dieselpunk, we're building the game we've wanted to play for years.
Nick has dreamed of IRON NEST for over a decade, and after meeting through developer-publisher collaborations, we decided it was time to bring this heavy spider-turret simulator, dripping with steel and power, to life.
Acknowledgements
The response has exceeded our wildest expectations. Thank you (truly) for every wishlist, message, and bit of support. It means even more because Heavy Turret Simulator is just the first step in the IRON NEST universe.


IRON NEST: Heavy Turret Simulator is a first-person heavy-artillery experience that blends tactical problem-solving, complex war-machine management, and strategic decision-making into a genre of its own. The inspirations behind the game range from 1990s anime and Cannon Fodder to Nick’s passion for engineering and artillery. Also, we would like to acknowledge PVKK, which, in our view, helped shape the genre in which IRON NEST proudly stands.

Roadmap, Reports & Resources
Remember, the first and most important place to stay connected with us has always been, and always will be, our Discord. That’s where Nick runs the game’s open development on a daily basis, discuss what’s happening behind the scenes, and stay in touch with Operators directly.
We also recommend checking our regularly updated FAQ thread on the Steam Community Hub, where you’ll find answers to the most frequently asked questions.
And if you’d like to share a suggestion, report a bug, or flag something that should be improved in the localisation, please head over to our dedicated Bug & Feedback Hub, also here on Steam.

As for what comes next, Nick is currently focused on the mentioned MID-MISSION SAVE SYSTEM that so many of you have requested. Then, starting August 24, gamescom begins. And both of us will be heading to Cologne.
We highly recommend keeping an eye on our socials, because we’re planning to organize a small meet-up with you somewhere on site. And once we’re back, of course, we’ll continue improving IRON NEST and move forward with the additional Skirmish Modes, as outlined in the roadmap.
Once Again: Thank You
High Command’s Propaganda Division is running out of ways to communicate this, Operators. Your reviews, feedback, and support continue to go far beyond anything we ever expected.
We know some of you may wonder why we keep repeating this in almost every announcement, but we simply don’t know how not to. Nearly 10,000 reviews, with 98% of them positive, is something we never imagined we would see. Thank you for making this possible.

Every time we think the front has reached its limit, you push it even further.
GLORY TO THE OPERATORS!

DAY ONE FRONTLINE REPORT
The opening hours of IRON NEST have been nothing short of extraordinary. Thousands of you have reported for duty, taken your stations, sent in field reports, and filled the Steam front with your reviews.
We’ve been reading your reports, and Nick is already working through them.
Today’s update is the first reinforcement to reach the front, shaped directly by your feedback. Thank you for every dispatch from the field, Operators. Please keep them coming through our dedicated 🔻 HUB // Reports, Feedback & Localization 🔻 thread here on Steam Community Hub. Every contribution helps.
As promised, launch was only the beginning! High Command is here for the long campaign, with frequent updates, patches and reinforcements ahead...

The support you showed us before launch already went far beyond our wildest expectations. But what happened after release is something we can barely put into words. We’ve said it before, and we’ll say it again: if games were judged by the strength of the community standing behind them, IRON NEST would be unmatched anywhere in the world.
Thank you for being here with us, Operators.
GLORY TO THE OPERATORS!
Nick & Dominik
