Anyone else wanna train with me?

Put a dot in the middle of your screen~

Uh i WOULD help you but my ps3 internet doenst work for some reason, but ill give you hints on how increase ur accuracy.
#1 ALWAYS stop moving before you shoot, if your still moving while you shoot ur going to shoot so far off its practically backwards
#2 6+ sensitivity you need to be able to play with a fast enough sensitivity
#3 point directly at your target before you shoot (you aim before or as you shoot)
#4 shoot as soon as you see the cross hairs
#5 practice and get better timing on when to shoot, better stopping to shoot reactions, better accuracy.

Add me

ill help u

basically u gotta get ur aim on the dude before going in scope. Have it on him then u go in and shoot.
Remember u shud always MOVE. There is a lotta recoil so u might hit.

Get into a lobby with friends and slowly crank up your sensitivity. It's important to do it slowly so you get accustomed to it. Other than that, just before you set off your shot, make sure you're not moving. Shooting while you're moving will bring down your accuracy a lot. By moving, I mean walking/running. Also, if you miss your first shot, lie down on the ground before you shoot another, it'll be harder for others to kill you.

All my friends play mw3...

People still play mw2? Just practice in a private lobby with friends and put your sensitivity to 9 or 10
