You can edit SPECIAL stats, skill points, armor class, damage resistances, hit points, add/remove perks, and probably a handful of other things as well that I just don't remember offhand anymore. Pretty much anything that appears on your character sheet can be changed.
Please give some straight forward info on how to cheat through this game.
