Demo of Artillery Simulator 'IRON NEST: Heavy Turret Simulator' Released on Steam
The demo's strong early reception and the game's niche focus on manual artillery operation-requiring players to handle everything from ballistic calculation to shell loading-suggest a growing audience for hyper-detailed simulation games that eschew direct battlefield visibility.

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.
The game's dieselpunk aesthetic draws inspiration from the battleship Bismarck, the Schwerer Gustav railway gun, the main guns of the Iowa-class battleships, and early French autoloaders, according to the developers. Players operate a 5,000-ton turret, using levers, handles, and dials to measure artillery strike points and set propellant charges.
The story is set in an alternate Spanish Civil War between monarchists and republicans. Players piece together fragmented information from orders, field reports, aerial reconnaissance photos, and wartime propaganda newspapers. The full version will feature 20 unlockable abilities and 15 regions. The demo includes 8 challenge modes with algorithmically generated targets.
Localization into languages including Japanese is in progress with community support, but the demo version still has untranslated parts and areas needing correction. The developers recommend playing in English for now. The full version is scheduled for release in early August 2026, in the third quarter of the year, and will support Japanese.
