you cant realy sneak
they dont die in one hit so you will attract attention even if you got the chanch they will shoot at you through trees insted of going to cheack out the noise so you cant draw then to you and the are allerted by noise so no mater where you hide the find you. only way that might work is to crawl slowly and then you cant hide fast anough.
so ther is no way to sneak around you can get in but only because when you die only you come back everon you killed will stay dead but it is till a realy agrovating not at all fun
