I was laying down on tall grass using the PVG to take down an Apoc Tank. Using the PVG I expected trouble to come. I hear a few runners but am surprised I am not being shot at. I stand up, and there they were. Two Runners about 2 car lengths away from me looking around as if they couldn’t find me.
I never considered tall grass to be a deterrent if you are laying down, but now I am curious to test it some more.
I’ve been able to creep real close to Machines laying down, it really helps stealth gameplay. Yesterday when I was out hunting FNIX Machines for that EMP challenge a Tank walked past me just 2 meters away where I was lying down in some underbrush.
It also helps stabilizing your shots when sniping. I’m really glad it got added into the game.
American metric system be like :
That is real interesting. My next goal is seeing how close I can get to machines laying down on grass lol.
I was going to put a distance like x efeet and then convert to emeters, but I figured an average car lenght is something a little more universal. 
If this game has the ballistics from theHunter: Call of the Wild, then I would guess the same stealth system is implemented at least on some level.
By the way; tH:CotW is the best hunting game there is 
Palle, I have it! I haven’t had much play with it, though.
Yeah, going prone is great for stealth. Almost too great! I feel like there’s a noticeable divide between prone and standing and crouching; when you stand you’re spotted almost immediately, and then on the other end of the spectrum during prone you are almost invisible.
Thats cool, i was hoping going prone would actually make a difference, going to have to try this out.
Newer guy here, prone has always been in the game for me because I only have 130 hours. It came as totally natural to me that grass would decrease my visibility and the hiding and stealth makes a lot of sense in the game, when you make noise or move fast you get seen. You can move directly below a tank or harv when prone, and I really think having three stances makes a lot of sense in GenZ.
Only thing that really drives me nuts is that certain foliage that is 0% transparent does not block enemy vision, mostly the cut bushes around a church.
So I was proning, using probably the loudest gun in the game, and they were not seeing me. Don’t you guys think they would have zeroed in on my fantastic noise maker?
