I practice and I practice but i still aint good enough. Below is a list of what I do.
-I have my own scope (with a dot in the middle) it's very accurate
-I have my own cross hair (green cross hair and the middle is black and thinner
-I put the mouse sensitivity to the max
-I learned to walk when i hear someone in the next room
-I learned all of the maps
-This is my key order
a=tilt head left
s=strafe left
d=walk back
f=strafe right
g=tilt head right
e=walk foward
r=use key
t=reload

Can anyone improve me like maybe a good website that has stuff like how to approach a door or window and stuff like that. I really need better aiming. I also would like indivisual tips to improve my games
