Is there a way to edit game files in order to disable parts of the HUD, such as the compass and ammo/weapon condition parts, while keeping the aiming reticule?

It's easy to make the HUD totally invisible via settings, but aiming is too annoying for my tastes that way. Would be great to disable everything but that targeting bit.

I'm on 360. I can turn off the HUD, but lose my targeting reticule. Which, is kinda fun and new to play with... and now I don't use the reticule anymore.

It would be nice to have a Laser Dot sight, they've got laser weapons so would of thought they'd have developed something.Ah well don't need reticules for melee weapons. "Now stand still while I cave your skull in with this here bit o lead you giant green lummox"
