~Weapon degradation adjuster.
~Real time in game or slower time.
~Bullet stopping power effects against AI = staggers the AI.
~Bullet Penetration. Penetration causes damage through walls. Damage taken or delivered through walls is slightly decreased based on material, distance, and objects hit. Example: 95% dmg through door, 80% dmg through wall, 60% dmg through wall and cabinet.
~Character/AI foot steps noise level adjuster. Also, an AI voice level adjuster. Both are too loud. Greatly decrease the number of AI voice instances. I understand it makes the game easier/ more enjoyable, but simply who tf would really taunt you in a life or death situation or war zone? Maybe the rare dumb ass but no.
~Noise affected by walls/muffled.
Secure container/pocket(s) maybe? I'd try but I don't have much experience. or maybe some system where u keep ur primary and secondary weapons/ attachments but lose ur backpack etc?
Niche, and maybe won't be used as much as people might anticipate, however it would be a fun experience, however a VR MOD would be pretty dope!
