Demo of Artillery Simulator 'IRON NEST: Heavy Turret Simulator' Released on Steam

Independent developers Nick Nieuwoudt and Dominik Latos have released a demo version of 'IRON NEST: Heavy Turret Simulator' on Steam, coinciding with the Steam Next Fest: June 2026 Edition. The game is a first-person heavy turret simulator set in an alternate history of Spain in the late 1920s, where the monarchy did not collapse and World War I did not occur. Players operate a massive four-legged land artillery fortress called the 'Iron Nest,' following orders from high command via radio communication. They must manually calculate ballistic trajectories, measure distances, set propellant charges, and load shells from a selection of 30 types, including armor-piercing, smoke, and gas rounds. The demo includes a Campaign Mode that tells a story indirectly through orders, field reports, aerial reconnaissance photos, and propaganda newspapers, as well as a Challenge Mode with leaderboards. The full version is planned for release in early August 2026, with localization into languages including Japanese in progress. The demo has already received over 1,400 reviews on Steam, earning a 'Very Positive' rating.
