The developers of IRON NEST: Heavy Turret Simulator announced the game will launch on Steam on August 7, 2026. The diesel-punk artillery simulation puts players in control of a 5,000-ton turret in an alternate-history 1920s Spain where World War I never happened and monarchies still rule. Players receive orders from high command and front-line reports, then manually calculate firing solutions using dials and levers, select from 30 shell types, and fire. The demo, available since earlier this year, has drawn over 5,000 user reviews on Steam with 99% positive ratings, earning an "Overwhelmingly Positive" status. During the June 2026 Steam Next Fest, the demo ranked second among the top 50 most played demos. The game's wishlist count has exceeded 500,000. The full release will include a campaign mode and eight challenge modes with leaderboards. The game supports Japanese display.
IRON NEST: Heavy Turret Simulator is set in a fictional late-1920s Spain where European monarchies did not collapse and World War I did not occur. The country is on the brink of civil war between the royalist army and republican rebels. Players operate the Iron Nest, a massive turret, by manually adjusting hydraulic devices, inputting coordinates into a ballistic calculator, and selecting the appropriate shell for each mission. Shell types include armor-piercing rounds for bunkers and smoke shells to cover retreats. After firing, results are shown via aerial photos and newspaper articles, and each shot can affect the story's progression. The game also presents moral dilemmas: orders from headquarters may conflict with local intelligence, and players must decide what to believe. The demo's success-over 5,400 reviews at the time of writing, 99% positive, and a second-place finish in Steam Next Fest's most-played demo chart-has built anticipation. The full version will add eight challenge modes with leaderboards alongside the campaign. The developers have not specified a price.
