The people in your outfit that you rely on to do everything in this town.
In vehicles or managing an operation, your crew members make it all happen in your outfit. They can be put in charge of deliveries that will help you move goods around town. They can be armed with weapons to deal with recalcitrant hooligans or to send a message to a rival outfit.
Your capacity for crew members can be increased by expanding your territory and gaining control of additional buildings.
Look for businesses where owners owe you favors and know, know someone who might be a good crew member. Be sure to make sure that their traits match up with the jobs you have in mind for your potential crew member.
