After playing the game for quite a while now ive come up with a few Mod ideas
-NVG's/Binoculars We desperately need these asap
-Visibly holstering weapons across your chest
-Helmet Equipping animations/gas mask overlay/rain effects on visor
-Tarkov Style mag loading Like in ESP
-Gun checks/inspections
-Better Flashlight Brightness
-Tinnitus Effects from explosions
-PDA Animations
Ill Add more as I think of them but this is the main mods I think that could really help the game as a whole for not only immersion but overall QoL improvements
-Hardcore mode aka needing sleep water and food
-smoking animations
-portable sleeping rolls or the ability to make your own shelter
-crafting of ammo/meds
-ability to see and or scan enemies to see what faction they belong to
