Actual working SNEAK mechaniks

[Maa22LT]

So i saw that many dislike how bad is sneaking, but I understand why, looking at the direction zombies are created in. Still I think it is possible to make sneaking-stelth gameplay emersive but still balanced.

Suggestion: impliment wind for sound and smell. For sound part you need  to monitor wind direction (in storm, mid+ rain or anything similar this efect is canceled out). Also make zombies smell blod, smell is caried with wind, but slower than sound, so its more important around ur base and places where you stay for longer. You can null this effect bay washing or using some aromatic plant(quick fix remedy). 

I don't know how hard this would be, so no big hopes for this one
