IRON NEST: Heavy Turret Simulator · published 12 Aug 2026, 17:19 UTC · build 24642854

All newsPlayers around this dateRead on Steam

Operators,

Tomorrow at 17:00 CEST, IRON NEST will be just one week old.

The response has honestly taken us by surprise. Your reviews, reports, feedback, and sheer amount of support have gone far beyond anything we expected.

The least we can do in return is make sure your reports keep reaching High Command.

Changelog


Version 1.0 (1618)

FIXED:

  • Fire On Call mission breaking if you kill all targets before the assault is declared
  • The final 2 medals in Rock of Gibraltar mission being unobtainable
  • Incorrect dates on several newspapers
  • Cursor locked in the main menu


IMPROVED:

  • Reduced RAM usage (15% of reported crashes were caused by out-of-RAM issues)
  • Phantom Battery mission balance


ADDED:

  • Colour Blind Modes (3 currently available - High Command awaits your feedback!)
  • Camera tilt customization slider while walking
  • Toggle to turn on/off world space input hints
  • Camera shake customization slider


Pevious patches: [Patch #3] • [Patch #2] • [Patch #1]

Steam Reviews: High Command Appreciates Your Feedback


We’d really appreciate it if you took a moment to leave a Steam review for IRON NEST. Nick is trying to read every field report and reply whenever he can, so even if we can’t answer every Operator, know that your feedback is reaching High Command and helping shape what we improve next.

Field Briefing: Roadmap, Reports & Resources


The first and most important place to stay connected with us has always been, and always will be, our Discord. That’s where Nick runs the game’s open development on a daily basis, discuss what’s happening behind the scenes, and stay in touch with Operators directly.

We also recommend checking our regularly updated FAQ thread on the Steam Community Hub, where you’ll find answers to the most frequently asked questions.

And if you’d like to share a suggestion, report a bug, or flag something that should be improved in the localisation, please head over to our dedicated Bug & Feedback Hub, also here on Steam.


As for what comes next, our main focus in the coming days will be continuing to polish Heavy Turret Simulator and address the issues you report. At the same time, Nick is already laying the groundwork for the new Skirmish Modes promised in the roadmap, so expect High Command to declassify some of its orders regarding this matter soon.

Tune In to High Command Communications


Every loyal citizen of Castile is hereby requested to stay tuned to High Command’s propaganda channels for all official broadcasts, field reports, deployment updates, and other news from the front: Discord, Twitter, YouTube, Facebook, bilibili, Instagram.

More than 400,000 Operators have now reinforced the IRON NEST


What started as a dream shared by two people has become something far bigger than we ever imagined. Thank you for giving that dream a chance, and for standing with us.

GLORY TO THE OPERATORS!

Nick & Dominik
