Liquid nitrogen gets a little complected. Here is my advice. The best Sci-fi is based in reality as much as possible. It makes your story much more believable. Now I have see some pretty cool water cooled guns. Water absorbs a tremendous amount of heat much better than Liquid nitrogen can. How about having her guns attached to her own artificial circulatory system. Only she can fire them without them malfunctioning, and she can use the extra heat generated by the guns to increase her own ability to function during combat.
