What people are saying
Overwhelmingly positive: a satisfying, immersive artillery sim with great sound design and a cat.
Players praise the game's immersive machinery and sound design, calling it "the poster child for good sound design" and noting that you can observe, hear, and feel the machine around you crank and whine. The cat is a beloved feature, with one player saying "you can customize the said cat" and another describing how you can carry them around for cuddles. [6][5][2][20]
Some players find the game too easy or simple for long-term play, with one saying "the game is decent, but far too easy" and another noting "a bit simple for the long haul." Others request co-op or multiplayer, with one player stating I would LOVE to be able to Co-op in this game with up to 4 friends. A few also mention the lack of mid-mission saves as a drawback. [15][19][7][35]

Critics, per Wikipedia
Iron Nest received "universal acclaim", according to review aggregator Metacritic. Writing for PCGamesN, Paul Kelly compared playing Iron Nest to reaching a flow state at a manual job, describing the work of mechanically operating the turret as satisfying and engrossing, and that "It makes hitting that target so much more satisfying knowing that I did everything with my own two hands". Kelly described the game as a test of the player's organizational skills and specifically complimented the implementation of the in-game notepad. Sean Martin of PC Gamer similarly described the mechanics of firing the turret as a ritual that became "strangely relaxing" with practice. Martin further described…

positive · reviewer's own thumbsView post →I think I would have had straight A+ in math class in school if they just told me I was calculating a white phosphorus artillery trajectroy to take out rebels. Fun game. - No performance issue on a laptop. - Has a cat - You can customize the said cat - Elementary school level math required
positive · reviewer's own thumbsView post →Awesome game, only thing i believe its missing its to make it co-op, i cant stop wanting been able to yell commands to my friend xD, overall this game has me hooked and i know for sure that my wife isnt fond of it hahaha
positive · reviewer's own thumbsView post →I'm a Marine Veteran, specifically an 0844 Fire Direction Control man. This game is not too far off how actual calculations for artillery are done - really impressed and brings back memories of conducting fire missions. To the developers, excellent work - very satisfying for someone who's done this in a real world scenario (the coffee maker at the start menu is a brilliant detail - the FDC runs on coffee!)
positive · reviewer's own thumbsView post →Played during next fest, absolutely fantastic. You can observe, hear, and feel the machine around you crank and whine and click when you do anything mechanical in the game. You enter a flow like state walking through the firing mission and I have NEVER had a more satisfied feeling than pulling the final lever to get the best THUNK/BOOM in all of gaming. As a bonus, the main menu also has an espresso machine. 10/10.
positive · reviewer's own thumbsView post →WHAT!? YOU GOTTA SPEAK UP! NO, THEY SAY IT'S NOT SERVICE RELATED! This game is the poster child for good sound design. The deafening shots and every metallic creak make the Iron Nest feel incredible. Overall it scratches a very specific itch if you love big machinery and doing repetitive procedures efficiently. As the levels go on you learn new ways to triangulate and you get your own workflow that feels really good.
positive · reviewer's own thumbsView post →I would LOVE to be able to Co-op in this game with up to 4 friends, so we could man all battle stations!
positive · reviewer's own thumbsView post →Mistakes were made, that hospital looked just like a terrorist and it shouldn't have been there in the first place.
positive · reviewer's own thumbsView post →They have called the 'tism, the 'tism answered, and now they have one of the best 'tism communities ever assembled. The game is essentially an autism simulator in the best kind of way, press buttons and pull levers and turn wheels. And, blow stuff up in the process. One of the very few true gems in development in recent history, not to mention done by a single dev! GLORY TO CASTILE!
positive · reviewer's own thumbsView post →Dear developers, Please stop making the game easier. Seriously. I don’t want the game to calculate the gun elevation for me. I WANT TO DO IT BY HAND. Give me the projectile mass. Give me the muzzle velocity. Give me the air resistance coefficient. Give me gravity. Give me the barrel length. Give me whatever cursed equations you are using. I want to sit there with a calculator, a piece of paper, and absolutely unnecessary confidence, calculating the firing angle myself. I want to miss the…
positive · reviewer's own thumbsView post →I bought the game as soon as it came out, and I know the next few hours will be fantastic. Thanks for the Ukrainian localization. Good luck, Iron Nest operators.
positive · reviewer's own thumbsView post →step 1: calculate trajectory step 2: load shell and powder charges step 3: aim and fire step 4: realise you loaded one too many powder charges step 5: watch helplessly as the shell you just fired sails right over the enemy and nails an entire friendly battalion
positive · reviewer's own thumbsView post →The games is simply amazing. Bonus points for the cat, i enabled the option in the menu so it can come upstairs and sometimes i have to chase it away since it likes to sleeps on the map. 10/10 super realistic
positive · reviewer's own thumbsView post →Hard to find such a polished, original, and clever game. The hard work of two persons, and you can sense the love that was poured into it. A blast, a must, the fame is deserved.
positive · reviewer's own thumbsView post →The game is decent, but far too easy. It’s good for a couple of evenings. My friends described it as something really challenging, where you’d have to use mathematical formulas to calculate things, but in the end, it mostly comes down to repetitive tasks. Only in one mission do you actually have to calculate the elevation angle of the gun yourself, and even that is about elementary-school level. If you have even a basic understanding of how to calculate values from one another or how to draw a…
positive · reviewer's own thumbsView post →There is a giant horn Not only are you operating a giant turret, but it also has a very loud horn. 10/10
positive · reviewer's own thumbsView post →Highly recommend this game to couples, or duos who communicate well together. Have one person on the keyboard feeding info to the second person with a notebook and pen, then completely ignore the in-game clipboard function, and pass info like bearings and distance back and forth as needed. Feels like being on a real firing crew!
positive · reviewer's own thumbsView post →Good game BUT it really need to be able to save game during missions as a single mission can take anywhere from 30 minutes to 1 hour.
negative · reviewer's own thumbsView post →Never thought calculating firing solutions would be fun and even kind of addictive.
positive · reviewer's own thumbsView post →A fun little game about slinging shells, but a bit simple for the long haul. It's worth the asking price though. Following will just be some personal grievances. In other "thinking under pressure" games (so something like Papers Please), you usually have a ramp-up in complexity as the game goes on, but Iron Nest has little more to introduce once you've seen your first moving target. Most missions are just testing efficiency with no time component, meaning that you're just doing light puzzles.…
positive · reviewer's own thumbsView post →So, there's a cat and you can do so much with them. You can carry them around for cuddles, you can shoo them when they get a little annoying, sometimes they'll roll over and sleep and you can stare at the little toe beans. One time, the cat purred and it was very cute which was great until I found out you could customise the cat! You can make them a heckin' chonky boi with big squishy cheeks and even give them a tiny little hat! It's very adorable. + it comes with a whole extra side quest…
positive · reviewer's own thumbsView post →Man sees giant turret Man buys game Man enters turret Man presses button Man fires cannon BOOOMMMMM Man is happy.. 10/10. this game is the best heavy artillery simulator ever made, the atmosphere is awesome, the giant machinery feels powerful, and finally firing the cannon is incredibly satisfying. GLORY TO CASTILE!! GLORY TO HIGH COMMAND!! GLORY TO THE OPERATOR!! GLORY TO CAT!! ALL HAIL THE IRON NEST!!
positive · reviewer's own thumbsView post →Shooting and hitting targets feels rewarding and every piece of machinery feels incredible to operate. I recommend to give it a try but I wish I could play this game in VR.

unlabelledView post →Absolutely peak game, GLORIOUS developers,, if you like artillery and you are at least a bit autistic about it, you have to try this, regional pricing too... Mmm absolute Peak, the only thing better is if there was not only multiplayer planned for multiple nests, but for multiple people in the same nest, but to be fair devs said they plan it as a different game, and from game dev perspective I'd agree, so 11/10

Join Greb at 5pm BST tonight at www.twitch.tv/iggymaid for an indie game showcase on an extended stream starting with Iron Nest! It has multiple chaotic games lined up for you all to enjoy ♥ All shares today can help us out a ton, thanks!
unlabelledView post →This game needs workshop integration for making custom scenarios! Great experience, didn't get boring at any moment. Nearly every mission has a gimmick spicing up the gameplay, for example I enjoyed very much the level where the distance calculator is broken. Sound design is VERY good, all these mechanical sounds are pleasant to hear.
positive · reviewer's own thumbsView post →Reaching for a colon likely means you're not confident that the name you've chosen does the job. Go back to that. (You are allowed to have a tagline that makes the game easier to search for, like Iron Nest: Heavy Turret Simulator, which has that in its Steam name but not in its key art.)
unlabelledView post →Digital crack, that's what this is. Anyone remember that old Basic game about two gorillas bombarding each other with bananas? This is a way more advanced version of that, one that will keep you glued to the monitor for hours if you aren't careful.
positive · reviewer's own thumbsView post →Glory to Arstozka! Wait, that's not who we're fighting for? It's Castille? Oh, okay. Glory to Castille! In all seriousness, as somebody from the artillery branch of an IRL military, this game is awesome. It scratches my artillery 'tism very well. I especially love planning out fire mission schedules, that's awesome. Open this game, do some math. Feel big brain while making big holes in the ground.
positive · reviewer's own thumbsView post →Iron Nest has the bones of a great game, but there is just not enough meat on it so far First off, if you want to experience the heavy war-machinery operation fantasy, Iron Nest delivers it, the machine is slow and chunky, the audio design is stellar. You can feel and hear the weight of every motion, every load, every shot. I enjoyed parts of the game. I love the war map, calculating distances, triangulating, measuring, it feels great. I love the occasional, but not constant time pressures.…
negative · reviewer's own thumbsView post →i love the game, its honestly so well polished, i will say that making this multiplayer or at least a multiplayer mode would be so cool. prox chat and job responsibilities between friends ensures good communication and strategy. i just think this could be cooler with 2-3 players
positive · reviewer's own thumbsView post →TL;DR: Best artillery sim mechanics I've played. Sabotaged by a memory leak and zero mid-mission saves. I bought this game to escape my math and physics classes, and somehow ended up paying fifteen bucks to sit in a claustrophobic dieselpunk metal box doing raw trigonometry. You spend ten minutes measuring angles on a map, arguing with a ballistic calculator, and sipping coffee while petting a gray and white cat with little gray paws who could not care less that you are about to vaporize a…
positive · reviewer's own thumbsView post →Who knew basic math with big booms would be this fun! Plotting a shot for a target you can't see and hitting it feels dreamy good. 10/10 for this absolute gem!
positive · reviewer's own thumbsView post →Very enjoyable for a game about math, triangulation, and trajectories. Immersive with interesting lore, lots to unpack and go at your own pace; of course: When there's no counter-battery.
positive · reviewer's own thumbsView post →Iron Nest is fascinating, I can see why people kept asking if I was gonna play it. The kind of tactile interactions with cranks and levers are exactly the kind of thing I love, definitely give this a look if you like that as well.
unlabelledView post →Its like a giant fidget toy, but with a higher probability of breaking the Geneva Convention Seriously though, this game is great, its realistic enough to be engaging and fun, but not too much to be absolutely punishing 10/10 Glory to Castille!!!!!!
positive · reviewer's own thumbsView post →If you or your kids find basic geometry or arithmetic hard or dull or unengaging, get yourself or them this game. It is a perfect educational tool about angles and simple numbers. To be included in every primary curriculum. Well done, devs!
positive · reviewer's own thumbsView post →Yeah, Iron Nest looks cool, I enjoyed the demo, but I've not picked up the game yet, I'm adamant about wanting to finish Routine first. I don't want more half-played games I'm annoyed at myself because I didn't finish.
unlabelledView post →Just...fun. My ADHD Autistic brain absolute loves the loud clanky sounds of shoving shells in, marking the map and getting my shots right, ALL of it just combines into a genuinely pleasant experience. Highly recommend.
positive · reviewer's own thumbsView post →Worth every penny of $20. Well polished. Simple. Runs well. Quality every indie dev should strive to produce.
positive · reviewer's own thumbsView post →Only in the game Iron Nest can you snipe the RMS Lusitania with an 800mm, high capacity-high explosive round going 700 meters a second, (Mach 2) with a blast radius leaving a half kilometer wide crater in the ocean. War crimes have never felt so fun :D

positive · reviewer's own thumbsView post →Played it during NEXT Fest on recommendation from friends. My thoughts; -Simple but well designed. Thankfully, factors such as Coriolis effect and atmospheric state do not need to be calculated for gameplay. -Art direction and sound design amazing. From the handwheels that spring steam when the guns fire, to the war horn, the rhythmic beat of the counterbattery timer ticking as you plot solutions, devs nailed this right out of the gate. -Feedback accepted from the demo build. Stuff like the…
positive · reviewer's own thumbsView post →I played the demo during Next Fest, I played it on release and I found myself incredibly satisfied with Iron Nest no matter what. I don't know what it is about Iron Nest but to put my feelings about the game in the fewest words possible: I BLOODY DAMN WELL LOVE IT AND I WHOLEHEARTEDLY RECOMMEND IT. (Yes, the emphasis is mine.) Iron Nest is a game roughly set around World War 1 to the Interwar period, in the kingdom of Castile within an alternate history Spain, and you're the sole operator of…
positive · reviewer's own thumbsView post →Castile has provided me with walking heavy machinery to protect us from enemies. Castile has provided me with means to rain hell on ones that dare to rebel against the great Castile. With Castile selfless support it is my duty to selflessly support Castile and its mission. Castile made it very easy on me considering a fantastic polish regional pricing for a machine, that provides lots of fun. Glory to Castile
positive · reviewer's own thumbsView post →I followed the game before release, read the Discord and Steam discussions, and the developer was always very open about the game’s intended scope and what it was not trying to be. This isn’t a complaint about false advertising. It’s more of a warning for people who see “Heavy Turret Simulator,” all the machinery, and the Overwhelmingly Positive rating and assume there is a deep artillery simulation underneath it. There just isn’t. IRON NEST is very good at giving you the feeling of…

positive · reviewer's own thumbsView post →Another 'Steam Deck Verified' game where the developers have clearly never even tried to play their own game using a controller. Background menus continue to be interacted with while a different menu is on top (eg: map zooms in and out while scrolling the clipboard), among a dozen other issues that would have been found within 10 minutes of playing. It's not a small oversight, it is --IMPOSSIBLE-- for the developers to have played their own game using a controller and shipped it saying…

positive · reviewer's own thumbsView post →Iron Nest has an interesting concept. The game revolves around triangulation - essentially very basic geometry using coordinates and information from spotters/intelligence to work out where to aim your cannon. It's a neat mechanic at first, and figuring it out during the first couple of missions is actually quite satisfying. The problem is that you nail the mechanic after about two missions… and that's basically 95% of the game. The core gameplay loop is: Get coordinates/intel → do some…

positive · reviewer's own thumbsView post →its overwhelmingly positive so pretty much everyone knows its great. But for those who like this kind of gameplay (playing with maps, maths, drawing, calculating), another game called "MAP MAP" is another indie hidden gem.
positive · reviewer's own thumbsView post →ah yes, i can't believe they copied iron lung by placing you inside a metal vehicle, having a gridded map, and using iron in the name jokes aside, this game goes hard. every shell feels like nuclear bomb, and the steps to learn are quite intuitive and pretty clearly explained. i love the crunchy style with its shell loading animations, typewriter commands, and angle adjustments. to me, the atmosphere feels very much like papers please, a game which i love, and is something you might think as…
