IRON NEST: Heavy Turret Simulator launched on Steam on August 7, 2026, as a single-player first-person artillery simulation. The game is set in an alternate-history 1920s Spain, and its demo had strong pre-release demand.
IRON NEST: Heavy Turret Simulator is a dieselpunk artillery simulation developed and published by the duo Nick Nieuwoudt and Dominik Latos. Set in an alternate-history Spain in the late 1920s, the game places the player inside a 5,000-ton-class walking fortress called the Iron Nest. The player manually operates every lever, dial, and button, from reading telegrams and plotting targets on an operations map to inputting ballistic calculations and adjusting barrel angle and gunpowder. Over 30 shell types are available, including armor-piercing, smoke, and gas rounds.
The game launched on Steam on August 7, 2026. Prior to launch, a demo had been available since June 2026, coinciding with the Steam Next Fest. The demo drew over 5,000 user reviews with 99% positive ratings, earning an "Overwhelmingly Positive" status, and ranked second among the top 50 most played demos at the June 2026 Steam Next Fest. The wishlist count exceeded 500,000. The full release includes a campaign mode and eight challenge modes with leaderboards, and the game supports Japanese display.
Coverage emphasizes the game's niche focus on manual artillery operation and limited visibility, which rewards patience and precision. The developers say rotating the massive fortress takes considerable time, which gives the game its feel. The Steam page quotes Kotaku, which called the game "absurdly precise but satisfying." The game is single-player only, with future multiplayer planned.

GameBusiness.jp interviews Nick Nieuwoudt and Dominik Latos, developers of the diesel-punk artillery simulation IRON NEST: Heavy Turret Simulator. Released for PC on August 6 at 1,980 yen, the game puts players inside a giant walking cannon, measuring targets and choosing from 30 shell types. Nieuwoudt cites the original Crysis as his favorite game and Katsuhiro Otomo's "Cannon Fodder" as a major influence.
Nick Nieuwoudt, co-developer of IRON NEST: Heavy Turret Simulator, says the most moving feedback came from veterans who told him the game captures the real work of fire direction commanders and gunners. One said it helped them face PTSD-related memories. The diesel-punk artillery game, out on PC since August 6 at 1,980 yen, is built as a psychological simulator rather than a mechanical one, with the player choosing among thirty shell types.

IRON NEST: Heavy Turret Simulator, a first-person artillery simulation game, launched on Steam on August 7. Developed and published by the duo Nick Nieuwoudt and Dominik Latos, the game is set in Spain during the late 1920s, in an alternate timeline where World War I never happened. Monarchists hold power while republican uprisings spread, pushing the country toward civil war. The player operates the land-based artillery fortress IRON NEST, a 5,000-ton-class turret controlled through levers, dials, and buttons. Every step of the firing process is manual: reading telegrams from headquarters and the front lines, plotting targets on an operations map, inputting measurement values into a ballistic calculator, and adjusting barrel angle and gunpowder amounts. Over 30 shell types are available, including armor-piercing and smoke shells. Rotating the massive fortress takes considerable time, which the developers say gives the game its feel. The Steam page quotes Kotaku, which called the game absurdly precise but satisfying. The game is single-player only, supports Japanese, and a demo version is available.
