You take pride in a set of principles that you follow at all times. The specifics can vary, but they always involve “honorable” behavior. You will do nearly anything – perhaps even risk death – to avoid the label “dishonorable” (whatever that means to you).
The point value of a particular Code of Honor depends on how much trouble it is liable to get you into and how arbitrary and irrational its requirements are. An informal Code that applies only among your peers is worth -5 points. A formal Code that applies only among peers, or an informal one that applies all the time, is worth -10 points. A formal Code that applies all the time, or that requires suicide if broken, is worth -15 points. The GM has the final say! A couple of examples:
Code of Honor (Pirate’s): Always avenge an insult, regardless of the danger; your buddy’s foe is your own; never attack a fellow crewman or buddy except in a fair, open duel. Anything else goes. This is also suitable for brigands, bikers, etc. -5 points.
Code of Honor (Gentleman’s): Never break your word. Never ignore an insult to yourself, a lady, or your flag; insults may only be wiped out by an apology or a duel (not necessarily to the death!). Never take advantage of an opponent in any way; weapons and circumstances must be equal (except in open war). This only applies between gentlemen. A discourtesy from anyone of Status 0 or less calls for a whipping, not a duel! -10 points.
