Honestly, I don't know, I'd suspect you'd have to adjust the actionmaps.xml file, but, honestly, a 360 controller just doesn't have enough buttons to be used for MWLL. 3 weapons groups MINIMUM, zoom, coolant dump, eject, power up/down, auto-power down override, PTT (if you use it) all of the targeting buttons.... the list goes on. I'm sure someone here can give you the actionmaps to edit, but I'd suggest sticking with either K&B, or, even better, a joystick.
