Need some help

I dont want to buy anything

Well then you most likely aren't going to get a bypass unless you have friends in high places.

So basicly, these hacks for dayz are made for nothing, because you need to buy a bypass, and i hear survivalhack 3.7 is detected

Yes survival hack is detected, 3.7 is at least, and you need a bypass to use the hacks on here. They aren't released because if people release them they are patched almost instantly.

Ah, Maybe someone could send me it, I wouldnt leech it

No, yeah, these hacks are made for nothing and don't work, that's why there's so many hackers on DayZ, right?

You can use menus and scripts with a cheat engine that you don't have to pay for on non BattleEye servers, but there will be tons of hackers. Check here for more info about bypasses, menus, etc.
