IRON NEST Patch 9 adds Ground Truth skirmish mission

Patch 9 for IRON NEST: Heavy Turret Simulator introduces Ground Truth, the second free mission for the game’s Skirmish mode. The scenario puts players in a fire-support role for Castilian infantry, with enemy anti-aircraft positions hidden across the city and frontline reports serving as the main source of targeting information.

The update also addresses a set of issues affecting presentation, controls, and an achievement. The developer lists a wrong date in the Iron Road newspaper, Cyrillic field-report text overflowing its page during long missions, and a trigger-console animation that could leave the console unable to fire. The gold medal achievement in Phantom Battery has also been corrected.

Mission and patch details

Ground Truth is included in version 1.0 (1742). According to the announcement, it is the second free Skirmish mission released as part of the current content expansion. It follows Guarding the Strait, which the developer says remains available.

The new mission is built around acting on information from frontline observers. With reconnaissance photographs unavailable because of hostile anti-aircraft batteries, players need to use those reports to identify concealed targets and direct their shots. The stated objective is to provide accurate artillery support to infantry fighting in the city.

Patch 9’s fixes cover more than visual polish. The Cyrillic text correction concerns reports that could become difficult to read when they extended beyond the paper on longer missions. The trigger-console fix targets an animation issue that could prevent firing. The Phantom Battery achievement change resolves a condition that previously made the gold medal unavailable without killing friendly units.

The announcement also provides a short roadmap update. A Ballistic Calculator upgrade is planned for November, followed by another free Skirmish mission in December. The developer says PlayStation, Xbox, and Nintendo versions are in development, but does not give release dates. It additionally notes two DevGAMM award nominations and says the game has received more than 15,000 Steam reviews.

What this means if you are considering the game

For players looking at IRON NEST for its artillery-focused missions, the patch adds another free Skirmish scenario rather than a separate paid add-on. Ground Truth emphasizes interpreting reports from the front and choosing fire targets, while the accompanying fixes address text display, firing controls, and a medal requirement.
