I have been playin halo 4 for a while now. My two major concerns are i received code and redeemed it but i did not receive anyhting. Then the auto aim or whay ever it is. Is throwing off my gameplay. I can be in a middle of a battle and some one walks through scope and it automatically jumps on them which in the end denies the kill i had been working for? Also alot of lag to tell u the truth i hate loosing and if i empty a whole clip of pistol ammo at close range at an opponents head i expect him to go down... if im in the middle of an assassination the person should not disappear while being killed to turn around and punch me
