Iron Blight Patch Notes and Current Version

The newest official Iron Blight announcement checked by this wiki is Patch 1.04, published September 2, 2026. Use this page to see whether a route, puzzle, save, achievement, or combat tip came from an older build. It is a dated patch tracker, not a claim that every installed copy of the game has already updated.

Current guide baseline

Restart Steam after an update before retrying a blocked interaction. Keep a save from before a major machine or route transition; a patch may correct a bug but cannot always repair a state already saved incorrectly.

Patch 1.04 — September 2, 2026

• Added Quit and Save & Quit options.
• Added an option to skip the prologue and allowed the belt inventory to open without obstructing the map.
• Added map objective pins for the Workshop Key and Blowtorch.
• Added line-of-sight checks for mutant melee attacks; crouched footsteps no longer make sound.
• Changed vodka Quick Use so it is only consumed automatically when sickness is critically high.
• Fixed several factory, docks, South District, Prasnova map, and mutant-respawn issues.

Relevant pages: walkthrough, Prasnova route, and difficulty and modes.

Patch 1.03 — August 31, 2026

• Added Prasnova overview-map area labels and improved save triggers in the Dormitory.
• Made sickness and low-health effects more significant and increased sickness cured by vodka.
• Fixed Quick Heal, keybind, elevator, door, puzzle-object-save, and mutant-behavior issues.

Patch 1.02 — August 28, 2026

• Fixed door loading, keybinding, Iron Sights setting, and map-objective localization issues.
• Reduced Headless Mutant sound reactivity and adjusted mutant disengagement.

• Added possible fixes for the Prasnova boat repair and Workshop wire-door blockers.

Patch 1.01 — August 26, 2026

• Fixed the Punch Card's first-attempt failure and several menu, map, save-trigger, flashlight, and interaction issues.
• Fixed achievement awarding for End Of The Line, Recorded, Blightbreaker, Iron Might, and the hidden Red Express condition when the campaign is completed with the relevant modifiers.
• Made Sickness inactive by default on Hardcore and adjusted Kuvalda behavior.

Relevant pages: Punch Card solution, achievement guide, and difficulty and modes.

Launch hotfix — August 24, 2026

The launch hotfix addressed boat activation and disappearance, zombies that appeared to stand after death, and map objectives that failed to load. If a current save still shows one of these symptoms, keep the save, update Steam, and test from a point before the affected event.

How to report a version-specific problem

Include the installed version, map area, objective text, key item carried, and the last interaction before the problem appeared. A clear report helps distinguish an old workaround from a newly introduced issue. For route-specific help, use the full walkthrough or the relevant puzzle guide.
