I’ve been playing halo since the OG days. Infinite is awesome and is unique in a lot of ways IMO. That being said, I SUCK at this multiplayer. Yes its new and I didn’t get into the initial beta, but man, I have been messing with my aiming controls and I just can’t seem to get it down. Does anyone have any tips or things that can be done to make it easier? I feel like its too sensitive no matter what I do.
A lot of practice definitely. Try out the weapon drills. My aim got a lot better after practicing some time in the drills, so hopefuly it can be the same for you! 
As a PC player, some disagree but every PC player knows we have the disadvantage here. IDK why ur using (i assume controller) but there isnt aim assist so aiming is a mess…need like 1 sensitivity
They decreased or removed a lot of the bullet magnetism and aim assist. I can’t play on 10 sens anymore I’m all the way down to 3 its not great…
I prefer the aiming in this game, makes the game more challenging and fun. Reminds me of halo 3 especially the sniping
The aim assist for me is strong. And the sensitivity is a bit off for controller on console
Aim assist locks on to players and then the moment you get shot while the aim assist is sticking to the player or they barely step out of the reticle the aim assist will unsnap off target and cause your reticle to fly way off target.
The point is we should compete with km users in some game mode.The aiming has to be improved.I have seen many KM players kill players with AR between half of the map.It’s disgusting.
