Latest IRON NEST Patch Notes and Current Version

Track the latest IRON NEST patch notes and current version through build 1663, including save/resume, mission and medal fixes, accessibility, and memory.

Current verified build

The newest official update verified for this page is Patch 6, version 1.0 (1663), published August 22, 2026. It adds saving when exiting a mission and continuation from that save.

Patch 6 also lists fixes for an Iron Road soft lock, Steam gold-medal achievements, an impossible Iron Road consecutive-kills medal, motion-blur behavior, a cat-related visibility issue, and missing supporter names or credits.

Important earlier launch changes

Patch 4, version 1.0 (1618), corrected mission and medal issues, reduced RAM use, adjusted Phantom Battery balance, and added color-blind modes plus camera and world-space-hint settings. Patch 5, version 1622, fixed application of the color-blind modes and other minor presentation issues while Save & Resume was being developed.

These notes describe listed changes, not a guarantee that every superficially similar bug is fixed. Record the build number and reproduction steps when reporting a current issue.

What comes next

The developer news hub says work continues on polish and future Skirmish modes. Those plans do not have to be present in version 1663, so this article separates shipped changes from roadmap statements.

How to verify after this snapshot

Open Steam’s Update History, compare the newest post’s version number and date with 1663, then read each later changelog in order. Community summaries can help discovery but should not replace the developer announcement.
