Steam’s Latest Military Sim Lets You Load a Massive Cannon for 30 Minutes of Epic Gameplay
June’s Steam Next Fest has been a bit of a letdown for me. Sure, there have been a few standout titles, but sifting through the mediocre offerings to find the gems has felt tougher than ever. Maybe I’m just getting more selective, or perhaps it’s the influx of AI-generated content cluttering the event, but this time around, Next Fest has been a frustrating experience.
However, there’s one game that has made it all worthwhile. To be honest, I didn’t stumble upon it by chance, nor did I dig through the endless list of demos; it’s been sitting at the top of Steam’s trending tab. Plus, the developers have been sending me some entertaining emails about it.
You’ve probably seen the title pop up on Steam recently, so you know I’m talking about Iron Nest: Heavy Turret Simulator. This ultra-realistic cannon-firing simulator, crafted by a two-man team, Nick Nieuwoudt and Dominik Latos, boasts an impressive 99 percent Overwhelmingly Positive rating on Steam.
My earlier rant about the disappointments of Next Fest is relevant because, honestly, if I hadn’t been so underwhelmed by June’s lineup, I might not have given Iron Nest a shot. At first glance, it didn’t seem like my type of game. Sure, firing a massive cannon sounds exciting, but military simulators aren’t usually my thing. Yet, despite my initial reservations, Iron Nest has turned out to be one of the best demos I’ve ever played.
You might be curious about what you actually do in Iron Nest. I wasn’t exaggerating when I said it’s all about firing a massive cannon. More accurately, it’s about loading that cannon. You take on the role of an unnamed Operator working for a shadowy and cartoonishly evil organization called High Command, a faceless military group that communicates orders through an old typewriter.
High Command is blunt in its directives: they provide coordinates or rough location estimates and specify the type of artillery to use. However, there’s also a second typewriter that delivers messages from troops on the front lines, and these messages are often more colorful and sometimes directly contradict the orders from High Command. Iron Nest doesn’t try to trick you into thinking you’re a hero; it’s clear you’re working for the bad guys. Following the orders in the first mission leads to significant collateral damage, including the destruction of an allied hospital near your target. High Command was aware of its presence and didn’t care.
While the setting and the dieselpunk aesthetic are surprisingly engaging, the real star of Iron Nest is, well, the Iron Nest itself. Targeting an enemy isn’t as simple as clicking a map and pulling a trigger. It’s a complex process that involves calculating the enemy’s position and meticulously loading your dual-barreled cannon. Every action in Iron Nest feels tactile and incredibly detailed, making it immensely satisfying.
You start by jotting down High Command’s orders on your clipboard, then chart the range and bearing from the Iron Nest to the target on your oversized gridded map. Next, you input that range into your Ballistic Calculator, which determines how many powder charges you’ll need and the required elevation. After loading the correct shell, you manually rotate your turrets using your bearing data, then input your elevation data… and finally, you can fire your massive cannon.
And that’s just the first mission. Believe it or not, things get even more intricate from there. Sometimes you receive incomplete target data, requiring you to estimate a location by physically drawing on your map. Occasionally, the Iron Nest will malfunction, forcing you to run around and fix things mid-operation. And every now and then, you might find yourself under fire from enemy cannons while trying to determine their position.
It might sound stressful and overwhelming, but I found it surprisingly relaxing. The strict order of operations and the need to engage your brain create a unique rhythm. Plus, every piece of equipment feels tangible. Rotating valves and pulling levers is so satisfying that even making a cup of coffee in the Iron Nest feels like a hard-earned reward.
Iron Nest is all about firing a big cannon, yet you’ll spend 99 percent of your time doing everything but that. It’s fiddly, it can make you feel a bit clueless at times, and it sometimes resembles the grind of a full-time job. But despite all this, it achieved something remarkable: it made me feel smart. Given my past experiences with simulator games, I shouldn’t enjoy Iron Nest, but I absolutely do. With so many incredible games on the horizon, I find myself most excited about diving into a military sim in 2026.
June’s 2026 Next Fest might be the worst one yet, but Iron Nest stands out as the best demo I’ve ever played on Steam. Here’s hoping this doesn’t lead me down a rabbit hole of watching World War I documentaries and painting realistic army figurines.
