The lights are on
Well,we all agree that Modern Warfare 2 is a great game, right? Campaign is easy enough, but when you get to Online, it's a whole different story. I remember the first time when I played that my final score was 0-15. That was terrible though I did get the accolade participant. I got better eventually, but then realized that others might have the same problems as me. Hope this helps!
SCAR-H: This is like the M4A1 on steroids. A heavy assault rifle with a slowish rate of fire. However, it makes up for damage. This gun is good with the attachments silencer, red dot sight, and FMJ for extra damage.
ACR: Another great heavy assault rifle. This gun has more strengths then the SCAR-H, like mobility, higher rate of fire, and better accuracy. However, this gun has less damage then the SCAR-H. Good attachments: Red Dot Sight, silencer, and grenade launcher.
AK-47: One of the world's first automatic modern assault rifle just went rambo. This is a all powerful gun good in every category. Need I say more? Good attachments, everything. Wonderful gun. It's like death in a can.
