Not much has changed with the rules for Dead of Night second edition, but one area that I’ve tweaked are the characters themselves. Victims in Dead of Night still have attribute pairs, specialisations and survival points, same as ever, but players can also choose a bad habit or two.
Think of a bad habit as a horror movie cliche personal to that character. So a character might have the bad habit “sneaks out for a cigarette at every opportunity”, and when they sneak off for a fag when they should be guarding the camp, they earn a survival point. It’s a simple enough rule, and hardwires in certain behaviours to each character.
