First off I would like to say that I think all shooters should have same controls, it would make it easier to switch from game to game.

MW2 is the only console game I have played for a while now [partly due to the fact I can only play on weekends due to school] and there is no control scheme that is the same as MW2 in reach, from what I saw on this site.

They should have a control set that is the same as MW2, or at least make it so you can customize your own set.

all games aren't like each other dude, that's just ignorant thinking.
it really depends on the controller settings too, like i use bumper jumper, even though it's not as useful as it was in halo 3, but the controlls work for me.
if you need to revert back to the h3 default controlls, go to the "Recon" setting

I do agree that they should let us map the controls however we want. Not just Halo Reach, but all games nowadays. There's no reason not to, and PC gamers have gotten to do it for the better part of a decade.
