Iron Nest Patch #4 Fixes Softlocks, Lowers RAM Usage, and Adds Accessibility Options

Iron Nest update v4 addresses mission softlocks, fixes unobtainable medals, and reduces RAM consumption by 15 percent. New features include color blind modes and customizable camera sliders.

Patch #4 for Iron Nest: Heavy Turret Simulator arrives to resolve critical mission softlocks, introduce accessibility settings, and curb memory-related crashes.

Bug Fixes and Progression Blocks

The Fire On Call mission no longer breaks if players eliminate all targets before the assault formally begins. The final two medals on the Rock of Gibraltar mission are now obtainable, newspaper date errors are corrected, and the main menu cursor lock has been resolved.

Performance and Balancing

Overall RAM usage is reduced to prevent out-of-memory crashes, which previously accounted for 15 percent of reported errors. Additionally, balance adjustments were made to the Phantom Battery mission.

New Customisation and Accessibility Features

Three color blind modes are now available, alongside a walking camera tilt customization slider, a camera shake customization slider, and a toggle for world space input hints.

Why this patch matters

Patch #4 tackles stability head-on while adding long-requested quality-of-life toggles and fixing broken achievement tracks.
