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.

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.
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.
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.

BIG GUN
[h1] “Not a doubt, not an option, not a thought - an Iron Nest review” [/h1] Cool, sure. Great sound design, awesome immersion, beautiful music, a great feeling that of sending huge shells across kilometres of terrain to demolish your hated enemy. But then you look deeper into what’s going on, and realize you’re not playing the game. The game is playing you. What is it that makes it cool to play tactical military games? Gather information on the battlefield based on partial sources, consider your options, choose what seems to be the best option at that moment, see the consequences of your action and readjust accordingly. All of which do not exist here. First. [b] Information[/b]. You know everything. Bearings and ranges are always exact. Every time your shells land, you get a perfect picture of the situation. Troops usually don’t move, which means the exact information you get once is useful for the following 20 minutes. A +/- 0.5° error at these ranges is insignificant. Especially with such big blast radii for the shells. Just pick a bigger shell and you’ll be good. Second. [b] Precision[/b]. In a dieselpunk 1920s fictional world, with multiple dozens gauges everywhere in the nest, with valves popping open and filling your cabin with smoke, you’re telling me your guns work perfectly 100% of the time with 0% deviation from your intended point of impact? Never ever do they miss your shot. I never missed a single shot, in 10 hours of gameplay, except for two human errors. The machine never misses. Gauges don’t mean anything. Accuracy is not an issue. Three. [b] Variables[/b] [i](or lack thereof)[/i]. Valves may open and release smoke in your cabin: not a problem, it does nothing. I survived half an hour with smoke everywhere and without the gas mask. Targets may be in the hills or on the sea: not a problem, altitude doesn’t matter. You may send an LE shell, very light and small blast radius, or an HCHE, very powerful and heavy: not a problem, all shells fly exactly the same. You are operating an artillery piece, it must mean there’s ballistic trajectories, that change based on gun elevation, and that there’s an optimum angle for max distance? Nope, not a problem. The gun is a linear equation. I didn’t solve it, others solved it, and it’s so damn simple a 10 yo kid could do it: range to target / max range with selected charges = gun elevation / maximum elevation (which is 60). That’s it. That’s a proportion. A linear proportion. You know the calculator in game where you put the bearing and range and powder charges and shell type and target type and all that? Yeah, meaningless. It is not meant to solve a mathematical problem too complex for you. No. It is meant to hide the stupidly easy operation you can do in your head on the fly for every shot. It is meant to trick you into thinking this is a game about artillery and not a banal mathematical equation. Sorry, proportion. Multiply and divide. No thinking required. That’s the real problem of the game. After nearly 100 shots of hitting my targets with zero issues, I started thinking the game was too easy. Then I thought: “It can’t be, I’m not [i] that [/i] good at artillery stuff. I’m not doing incredible calculations, I’m just following what the machine tells me. I’m just a good listener”. That’s when it all made sense. I wasn’t doing anything. I was just listening and obeying, listening and obeying. This is a perfect game for this society, where nobody thinks and they just listen to whatever the unknown depths of “The Algorithm” spit in their face (whatever algorithm that may be, like the calculator here). If you just start thinking for a single moment, you realize you just paid to be hired by a machine to do what it tells you to do, simply because it can’t do it itself. That’s not playing a game. This is not a game. I’m not a genius. I was just following orders. That’s how fascists grow up. Stop following orders. Don’t buy this game. You’re not playing this game. The game is playing you.

There is simply nothing else like this and if there is, I want to know what! The visuals and the audio are absolutely top notch. The story is compelling enough. The gameplay is where it might fall flat for some. I absolutely love it but would freely admit that it can be repetitive at times. The gameplay loop of: Identify targets, draw target lines, feed angle and bearing to computer, load powder, adjust angle of turret and guns, fire and repeat is incredibly engaging. The different steps play out differently, the tools you use in the game feel meaty and real. They clunk when they should clunk and hiss when they should hiss. Ultimately it's lot of clicking to pull levers, set dials spinning and other fiddly bits, hoping that you drew lines to the right place on a map. If that sounds satisfying to you, then this is an absolute must have.
You have to manually open shutters every time. They automatically close every time you fire a shot. But hey, you have a useless feline on board instead, isn't it great. Game is OK overall.
Really wanted to like this, but several times I've loaded into missions where the bearings and distances are wildly off and don't line up, so no clues where to launch.
