I was struggling a bit until I saw this comment (below). I used his settings as a baseline and adjusted the dead zones as needed since my elite has some drift. The biggest thing is do not aim down sight in CQB. Hip fire while aiming for the head, jump, and melee just as you’re about to run out of ammo.The aiming in Halo is just awful. Either it’s too fast and the crosshairs moves right past opponents, or too slow and I’m killed before ever taking a shot. I’ve messed with the settings all day to no avail, and found that this is a pretty popular issue right now.Remember, frags are OP, pistols are deadly from range if you can get head shots, and finish off your assault rifle spray with a well timed melee. If you have an elite controller, try jumping/hip firing while engaging in CQB.
I don’t expect to be up there with guys who play 10 hours a day, but I had 0 kills and 18 deaths in the last match. I am not that bad.
It sounds like you’re having issues with the dead zones which for some reason default at 12. Lower that a bunch. Then also lower your acceleration to 1 or 0. Then adjust your sensitivity as needed.
