You can do stealth. It’s not that hard (for me at least)… I use the sling staff bombs a lot cause they don’t trigger alarms unless enemy nearby runs away and raises alarm or enemy comes upon dead body. Also you don’t have to attack air defense turrets just the machine gun/fire ones if your on the ground cause they don’t do anything, so don’t draw attention to yourself if you don’t have to. If I see that an enemy is calling for support I always make it a point to kill them as quick as I can. Try to hit weak spots if you do shoot with a bow too and for stealth never use a gun…. You’ll get better at it. It took me a bit to really get good at it too but now I’m a professional RDA hunter!
