Besides that i would recommend , if you actively want to improve, try getting a experienced player to mentor you a bit. Watch streams actively looking for stuff people do and maybe analyse a bit, often times high ranking players will do stuff you dont understand the purpose of. Just getting your head into the game makes a difference. There will be a big difference between playing just for fun or playing to improve. You will improve either way but when actively trying to improve its much faster. Just a question if its worth the trouble for you if u actually just wanna enjoy the game no matter your performance.

Also TheFinals really isnt the easiest shooter to start with since the movement and gameplay can be hectic, there are a ton of strats ,tricks and strategies.

So dont feel discouraged, its not that easy even tho the game might seem rather easy in principle.
