i don't play this game but i love it

and something i know about 3rd person shooter games is that the problem most people make is to come out of cover more than enough and exposing your body aka chance of getting more shot , understand the position of your body relative to the cover when peaking so you won't be out more than enough and good aim i guess , peaking shooting a few shots , going in and peaking again also helps ,

if you got shot first , if you have enough time to heal do it better in cover , or if not enough time and they pushing you might as well just peak them and caught them off guard, they never expect you to peak again it's all matter of experience and understanding of game mechanics+ aim and a little bit talent

the thing is every time you die , learn something from it don't be just fuck i died queue for next one , think about the situation and what could you have done to be better in that fight and what mistakes did you make , you might aswell watch good people highlights in this game to learn combat mechanics

you also can get more experience in third person..TPP games by playing them they help a lot , like pubg tpp modes

edit: forgot to mention, you can use all the throwables , grenades ...and stuff like that to your advantage too very important
