After reading playahata's guide, i decided to try 1. Jesus christ it's like being born again. Just don't look up too far, because it takes a few seconds to get back down. If you mind going to far, it actually kicks ass for brs. I'm a level 44, and have over 2000 games played so don't think it's for noobs. Even walshy plays on 1.
I play on 10, in every game I play. Funny thing is, nobody ever believes me when I say that. Luckily it can be proven in Halo 3
I played on 10 for a while, then backed down to 7 because it just got annoying. I can BR a lot better because when someone comes from behind I just jump, spin, pop a grenade, and headshot.
I play on three default. I've never changed it and never will because it is easy to aim with every weapon and it is quick enough to turn around quickly if someone is behind you.
Ok For Team Swat and MLG I use 2 and for team snipers I am just now switching from 1 to 6 and Im deciding which one fits me the best. I am kind of debating between 5-7. But ya Im getting used to the new one
It helps a lot with your game if you just find one sensitivity that suits you. What happens when you pick up a sniper in game and your sensitivity is to high? It will make you better.
I've always played Halo with 10 sensitivity. The only thing that has changed is the button layout for me on Halo 3 when I switched from default to bumper jumper.
2.5 the .5 comes from the dashboard. There is an option where you can change your controller sensitivity(goes for all games not just Halo 3) It actually is pretty well and comfortable to play with =P
