There is a thing in this game where if you run and shoot your gun at the same time, the gun’s bullet spread becomes absolutely horrible and it is basically impossible to aim your gun. So, when shooting, let go of all movement keys including w a s d, and space bar. This will make your aim 10 times better and you will get kills and rank up. I’m a bronze 2 who consistently gets people who run and gun as teammates, thank you for coming to my ted talk.

TL DR: Do not use w a s d, or space bar while shooting your gun, because your accuracy becomes bad
