This update introduced several features that significantly changed the gameplay experience:

: The update introduced the GPNVG-18 ("quad-NODs") and white phosphor night vision options, which offer a wider field of view for night operations.

: Enemy AI was given a light detection system, meaning they can no longer see perfectly in the dark. They also now "rush" players when only a few individuals remain.

If you are attempting to install this specific build from a compressed .rar file found on a blog or third-party site, be aware that official updates are delivered through Steam. Developers strongly recommend when switching between major versions like v1033 to prevent asset and input issues.

: Added a bolt-action rifle and the ability to mount red dot sights on pistols. Important Technical Note

: Players received new customization options like callsigns, facial hair (full beards), and multiple patch locations on headgear and shoulders.
