In any situation that the GM feels is stressful, he will roll 3d. On a 6 or less, you have a flashback. The GM will roll whenever you miss a Fright Check or make the roll exactly, and whenever you fail a self-control roll for another stress-related disadvantage.
Make a self-control roll when faced with the “need” to break unreasonable laws; if you fail, you must obey the law, whatever the consequences. If you manage to resist your urges and break the law, make a second self-control roll afterward. If you fail, you must turn yourself in to the authorities!
