Has anyone noticed any noticeable changes when using the alternate-fire mode for the 'Merica? Pressing R rotates the "barrels" of the gun, but the only difference seems to be that the flamethrower will shoot from the bottom half of the gun, instead of the top-half. Am I missing something here, or is the alternate-fire mode for the 'Merica only a change in where the flamethrower shoots from?
