Im pretty bad at this game

before anyone says anything, I don’t hate this game. In fact I think it’s a great game. The fact is is that no matter what I do, I can never go into enemy territory without dying. I’m always dying to the most basic enemies and the weapons I use only do moderate damage. I use the most powerful weapons I have and I still suck. In games like this I’m usually pretty gung-ho and like shooting up enemies, but here u find myself trying to stay away from conflict. are there any tips you guys can give me to up my playing experience? Or do I just have to ”get good”?
